Which Roof Has The Best Fire Protection?

Fire is one of the most powerful elements on Earth. We use it for cooking food, creating art, creating electricity, and so much more. However, while fire has the potential to create, it also has the power to destroy.

Wild forest fires have destroyed major ecological environments, and they’re a pretty common occurrence in Maryland. On average, the Maryland Forest Service responds to about 123 wildfires that burn more than 1,780 acres of forest, brush, and grasses. The state’s fire departments respond to over 5,000 wildfire incidents per year.

In suburban areas, freak accidents and lightning strikes are common causes of fire outbreaks. In areas where buildings are right on top of one another, fires have a greater chance of spreading from one building to another.

While the fire department is there to help put out all these fires, there are some things that you can do to help.

Fire-resistant roofing is a great way to protect your home and property from fire damage. If you live in an area prone to fires or lightning strikes, it is highly recommended that you invest in some fire-resistant roofing materials.

To help you determine which roofing material offers you the best protection, you’ll be pleased to know that roofing materials are graded according to their fire resistance. These are some roofing materials with the best fire protection:

Slate Roofing

Slate roofing is one of the most premium roofing materials on the market today. It has a Class A fire rating, which means that it is non-combustible and can withstand severe fire exposure.

A slate roofing system offers your home the best protection from the elements and, with the correct upkeep, can last you more than 200 years.

However, slate is quite a heavy roofing material, so it’s advised to consult with your roofer about the compatibility of your home before you install a slate roofing system.

Metal Roofing

Metal roofing also has a Class A fire rating. However, this premium roofing material is much lighter and more affordable than slate roofing.

Metal roofing is a highly energy-efficient material too. It has a high UV reflective rate, protecting your home from UV damage and keeping your home cool in the summer months.

The roofing material is available in different materials like copper, zinc, steel, and aluminum, and you’re free to style your roofing system according to your aesthetic. Once your metal roof has reached the end of its lifespan, you’ll be happy to know that you can recycle your old metal roofing panels.

Clay and Concrete Tiles

Clay and concrete tiles create highly durable, Class A roofing systems. While this beautiful roofing system provides your home with incredible protection and curb appeal, they need to be installed by professionals for you to benefit from the Class A fire rating.

This is because the clay or concrete tile has a barrel shape. This barrel creates a gap between the roofing material and underlayment. These gaps need to be plugged to prevent the fire from burning your roof and house down.

The 5 Most Popular Roof Shingle Colors in 2022

A brand new roof is a big investment that will last a long time.  With most asphalt shingle roofs lasting 20 to 30 years, when it’s time to invest in a new roof, you want to choose something that’s on trend but that also has a timeless appeal.

Shingle Color Trends in 2022

Home design trends are ever-evolving, and roof shingle colors are no exception to that rule.  Unlike the paint in your bedroom or kitchen, though, your roof color isn’t quite so easily changed, so you’ll want to make sure your new roof color is perfect right from the start.  The most on-trend shingle colors in 2022 are:


Does black ever really go out of style?  The answer to that is no.  When it comes to a new roof, you can never go wrong with black shingles.  A black roof will always give a distinct yet neutral look that will complement any other exterior design choices.  Black is also a timeless color which is a plus when you’re looking at a 20+ year commitment.

Light Brown

Light brown shingle colors such as sand and taupe are hot in 2022.  As homeowners are falling in love with a more natural look, these lighter, warmer colors are increasing in popularity.  Light brown shingles are the perfect companion for the wood and wood-look exteriors that more and more people are opting for, lately.  Plus, lighter roofs have the added benefit of being more energy efficient because they reflect more UV rays!

Dark Brown

Like light brown shingles, dark brown shingle colors like autumnal brown and tree bark are an excellent complement to natural toned exterior designs. Far from blending into the background, these colors offer a striking balance for off-white, beige, and tan siding giving a modern edge to the natural look.


As we’re swiftly diving into the 2020s, designs are becoming bolder and shingles in shades of blue such as denim, navy, and sky blue are growing in popularity.  Gone are the days of boring and safe grey shingles.  Blue shingles can offer everything from bold contrast to whimsical comfort depending on the color of the shingle and the way it is paired with the siding and fascia.  The desire for these azure shades is only expected to grow throughout 2022 and beyond.


Yet another incoming shingle color that is expected to see an increased demand in 2022, green hues like forest, hunter, and moss offer a unique look that is both rich and inviting.  Green shingles perfectly complement warm, natural exteriors while still setting your home apart from the crowd.

Why Does Roof Color Matter?

When it comes to exterior home design, roofs often get the short end of the stick.  Roof tend to be looked at only for their function and their aesthetic is overlooked.  And while a neutral roof may not be a big deal in the overall design, a roof color that doesn’t match the rest of the home will stick out like a sore thumb.  The roof is one of the most visible parts of the exterior of the home, after all!  A well-designed roof offers many benefits to a homeowner.

  • Boost Curb Appeal

A mismatched roof can really kill the curb appeal of your home.  Integrating your shingle color into the overall design of your exterior will make all the difference for a beautiful, cohesive exterior.

  • Increase Value

A brand new roof offers a huge return on investment, and choosing an on-trend shingle color will be sure to have potential buyers drooling over the home if you’re in the market to sell or will help you maintain the value of your home if you’re planning to stay for a while.

  • Save Money

Believe it or not, your roof color can help you save money on cooling costs, particularly if you live in a warm climate.  Lighter colored roofs reflect more UV rays than darker colored roofs instead of absorbing them by means of something called the albedo effect.  This effect has been proven to offer significant energy savings over time.

  • On Trend Design

When it comes to home design, particularly for a home you hope to sell one day, staying on trend is imperative.  Balancing new trends with timeless appeal when choosing the color of your shingles will keep your home beautiful for years to come.

Choosing the Right Shingle Color for Your Home

Choosing a shingle color isn’t as simple as picking your favorite color and running with it.  It’s important to choose a color that meshes well with the rest of the design elements of the exterior of your home.  Some of the most important things to consider when deciding on the best shingle color for your home are:

  • Home’s Architectural Style
  • Warm or Cool Design
  • Location and Neighborhood
  • Climate
  • Siding Material and Color
  • Fascia and Gutter Colors

Pro Tips to Determine the Best Roof Color

The most important factor in determining the best roof color for your home is making sure you choose a color that makes a cohesive design with the rest of the elements of your home’s exterior.


Appropriately pairing your siding and shingle colors is a big deal when it comes to designing the exterior of your home.  The design choices made can entirely change the look and feel of the home.  When choosing your shingle colors, you’ll want to consider your existing or new siding color and decide how you want them to interact with your roof color.


With all the talk of color, it’s important to remember the role that textures play in exterior design choices.  Like colors, you’ll want to make sure that the textures are complementary while also making sure that the quality of the materials is the same.

Soffit, Fascia, and Trim

Accessories can make or break a design, and roofs are no exception to that rule.  Soffit, fascia, and trim are an excellent place to utilizing both contrasting and complementary design elements to fully pull the exterior of the home together.

How Long Should A New Roof Last In Columbia?

We know that you need a roof over your head, and we want to make sure that you’re only covered with the best. At Certified Inc. Roofing, our excellent workmanship is only outdone by the quality of our roofing services, in which every project gets dedicated attention from start to finish. We’re confident when people call us “the best” because not only do we offer friendly customer services but also fair prices without sacrificing value or integrity.

We know that installing a new roof can bite a large chunk out of your savings, and it is a significant investment, but it is also something that you wouldn’t want to do too often. Most roofing systems can last up to 30-40 years, sometimes even longer when properly cared for and maintained. Minor maintenance may be a short-term bother, but it is much less of a problem than repairing major roofing issues or replacing the entire roofing system.

The durability and lifespan of your roof are dependent on several factors, including environmental conditions, exposure to the elements, and the quality of installation by your roofing professionals.

Living in Columbia means that your roof is regularly exposed to things such as hurricanes, tornadoes, severe storms, and more. These environmental conditions can significantly impact the lifespan of your rooftop and lead to its accelerated degradation.

Let’s take a look at which roofs last the longest in Columbia and thus be easier on your pockets.

Asphalt Shingle Roofing

Asphalt shingle roofing is one of the most common roofing materials in Columbia. It is a popular option due to it being relatively cheap and easy to install. However, their lifespan can be anywhere between 10-30 years. Asphalt shingle roofing systems suffer during the severe weather conditions experienced in Columbia. Their lifespans may be shortened as a result.

Metal Roofing

Metal roofing is believed to be the most environmentally friendly roofing material available. The metal roofing is often made from 100% recycled materials. Not only is the roof eco-friendly, but it is also cost-effective as it has a lifespan of 30-50 years, and with proper maintenance, you can stretch this lifespan to nearly 70 years. Metal rooftops are best suited to Columbia’s climate. They can survive just about any storm, so you don’t have to worry about your roof suffering severe storm damages.

Flat Roofing

Flat roofing systems are known for being durable and highly weather-resistant. Commercial building owners prefer flat roofing systems due to their easy installation and maintenance. Flat rooftops have a lifespan of about 20 years, but their lifespan can be affected by things like environmental influences and foot traffic. Flat rooftops tend to be severely affected by hail and stagnant water. It is thus important to have functioning gutters with your flat rooftop.

4 Benefits of Asphalt Shingle Roofing

Asphalt shingles are one of the most popular roofing materials in the US. They’re found on about 70% of American homes, and their numbers keep growing year by year.

If you’re considering installing an asphalt shingle roofing system for your home, but you’re not quite sure what all the hype is about, well, then carry on reading as we detail the benefits of a professionally installed asphalt shingle roofing system.



If you have an aesthetic preference in mind, you’d be happy to know that asphalt shingles are available in just about any color scheme that you can imagine. They allow homeowners to customize their rooftops in any which way they please.


Easy Installation

Asphalt shingles are practically available in every roofing and hardware store across the country. If you decide to start your roofing project tomorrow, you wouldn’t have to wait weeks for an order to arrive the way you would have to wait for materials like tile or metal.

Installing an asphalt shingle roofing system takes about one to two days, so your daily routine won’t be drastically interrupted by your roof installation project.



For those of us with limited financial means, an asphalt shingle roof is the most affordable option on the market. If you need to replace your roofing system urgently, this material is perfect for you.

The material’s versatility affords homeowners various price points, and because of their popularity, many roofers offer fantastic discounts, upgrades, and sometimes even free repairs.


Environmentally Friendly

Keeping the environment in mind, asphalt shingles have become an eco-friendly roofing option. These roofing materials can be recycled to create new roofing shingles as well as be incorporated into the asphalt mixtures used to create roads and sidewalks.

Advantages and Disadvantages of Metal Roofing

Metal is a high-performing roofing material. Its weather resistance, durability, and longevity have made it a favorite amongst commercial business owners for years. Homeowners have often been reluctant to install a metal roofing system on their houses due to its reputation of being incredibly loud and dull. However, the roofing material has developed in leaps and bounds over the years and has become a leading roofing option for residential and commercial purposes.

Metal roofing systems are tough and durable. They also work well for people seeking a contemporary look, but they have their drawbacks too. Read on to find out more about the advantages and disadvantages of metal roofing.





Metal roofing is often praised for its weather resistance and sturdiness. The roofing material can withstand most weather conditions and offers homeowners long-lasting protection from the elements. They’re able to resist wind speeds of up to 140 mph, their high reflectance shields your home from harmful UV rays, and they’re capable of shedding large snow loads quickly.


Low Maintenance

Why deal with the headache of maintenance when you don’t have to? Metal roofing is not only durable but also practically indestructible. If rust and oxidation are your concern, we recommend steel or copper as they both come equipped with natural protective layers that will ward off any corrosion for years on end without a single touch-up.



A large percentage of homeowners are two-minded about installing a metal roofing system because they believe that the roofing material only comes in one shade and one style. You’d be happy to know that due to metal’s malleability, you can have metal shakes, shingles, as well as tile and slate metal imitations installed on your home. You can hone in on the strength and durability of a metal roof while enjoying the benefits of other more expensive roofing materials.




Initial Cost

The initial cost of a metal roof might scare homeowners away, but it is a long-term investment. It has a lifespan of more than 50 years and requires minimal maintenance, making it the most cost-effective in the end.


Require A Specialist

To get the most out of your metal roofing system and ensure that it lasts as long as possible, you would require a metal roofing specialist to install your rooftop. Inexperienced roofing contractors may take shortcuts or not know what to do should when a problem arises. Using a non-specialized roofer may also impact your material’s warranty and your roofing insurance.



While metal is a highly durable material, if you live in an area that experiences golf ball-sized hail, chances are, over time, your roof may be covered with dents. But it’s important to note that any roofing system will suffer significant damage when exposed to such big hailstones, and rather than having huge holes through the ceiling, which you’re likely to experience with any other roofing material, one or two small but annoying dents is easier to deal with.

Why Is My New Roof Leaking?

Investing in a new roofing system can be quite exciting but pretty expensive at the same time. A new roof installation can give your home a new look and feel, adding significantly to your home’s curb appeal.

But installing a new roof is not just about visual aesthetics; it’s also meant to give your home the strength and durability necessary to withstand whatever mother nature throws at it.

By installing a new roof, it’s natural to expect all these advantages from your new roof. Therefore, there’s probably nothing more frustrating than experiencing roofing issues, like leaking, shortly after installing your new roof.

A new roof that’s leaking is a combination of poor workmanship and cheap materials. This is why it’s important to not go for the contractor that underquotes you, they could be inexperienced, unsure how long roofing installation takes, or the best materials to use.

At Certified Inc. Roofing, we will always provide you with a thorough roofing quote, transparent advice, and professional roofing services. If your new roof is leaking, don’t hesitate to call Certified Inc. Roofing.


Why Your New Roof Is Leaking


Your Shingles Were Incorrectly Installed

If your shingles are not accurately installed, there may be gaps between the roofing materials that will allow water to get in and soak through. If you’re unlucky enough for rain or snow to come by during this time, then these poorly installed shingles can easily fall off with no hope whatsoever, leaving a gaping hole where one was originally supposed to keep out the precipitation.

Your roofing materials need to be correctly installed and tightly fastened onto your roof for you to reap the benefits.


Your Flashing Isn’t Properly Installed

The point of roof flashing is to guide water away from critical points in your roofing system. These areas include the area around your chimney, skylights, and vents.

If it is not installed correctly, this may lead to water seeping into your home and damaging its interior.


Your Gutter System Is Faulty

Your gutter system is one of the most important features on your roof that help to protect your roof and home from water damage. If your gutter system hasn’t been installed improperly or is clogged due to a build-up of dirt and debris, there may be an increase in standing water on your roof. This often leads to leaking.

When installing a new roof, always make sure that your gutter system is in working order.


Your Roof Deck Is In Poor Condition

There may be leaking in your home due to your roof deck being in poor condition. If you’ve just had a new roof installed and there’s still leaking occurring, the chances are that your shingles were installed on a dysfunctional roof deck.

Roofers should be sure to inspect your home’s roof deck before installing the new material on it.

How To Make Your Roofing System A Little More Eco-Friendly

The green movement is on the rise with Americans learning more and more ways to reduce their carbon footprint. Even if you’re not ready to make a drastic lifestyle change, there are still many simple adjustments that everyone can easily incorporate into their everyday lives such as recycling aluminum cans instead of throwing them in landfills or replacing an old light bulb with one made from LEDs which will last much longer than traditional incandescent bulbs.

The embracing of environmentally conscious lifestyles has become increasingly common among US citizens who want to find new tips and tricks about how they can live sustainably while reducing waste simultaneously.


Today, we’ll break down how your roofing system can help you reduce your carbon footprint.


Installing Recycled Asphalt Shingles

Recycled Asphalt Shingles (RAS) is a new roofing material on the market. Developed by GAF, RAS is made up of 15% recycled asphalt materials that were sourced from tear-off roofing processes.

Every year, 12 million tons of asphalt roofing waste end up in landfills. By installing a RAS roofing system, you would not only be making your roofing system a little more eco-friendly, but you would be reducing the amount of asphalt waste produced every year.


Metal Roof Installations

Metal roofs are certainly the eco-friendly roofing system worth considering. Not only is metal made from recycled materials, but it can be easily recycled once your current roof reaches its end of lifespan – which is in like 30 – 50 years.

Metal reflects UV light better than any other material out there meaning you’ll spend less on energy bills and enjoy more natural heat protection for those cold winter months ahead.


Collect Stormwater

Usually, when an area experiences significant rainfall, this rain is efficiently transported away from your home via your gutter system. This water then flows into the nearest drain and is then taken away by the municipal stormwater pipes.

However, what if we told you that you could collect this water and use it for things like watering your garden or washing your car. Using this water, you can reduce your water bill and help save the planet at the same time.


Invest in Solar Panels or Solar Shingles

Solar panels or solar shingles are a great way to power your home with the sun’s energy. Embracing this clean form of renewable electricity in our homes can reduce how much we rely on heavy and polluting fossil fuel-powered plants, which produce billions of tons worth of carbon dioxide each year.

The federal government offers homeowners who have installed these technologies nearly $2000 in tax breaks as well. That means that not only will you be saving money from installing them but doing your bit to save the environment as well.

4 Non-Aesthetic Factors to Consider For Your New Columbia Roof

When you’re choosing a roofing material for your home, there’s a considerable spread of factors to take into consideration. Of course, you want a visually pleasing roof, but there’s so much more to your roof than its aesthetic value. You should take into account durability, as well as the weather conditions it is likely to endure.

Many homeowners don’t even know where to begin when it comes to these things, though. At roofing company Certified Inc. Roofing, we’re here to share a few important things to consider when choosing materials for your roof.



Not many people take the importance of their roofing materials into account, but it is relevant. A lightweight roof can significantly decrease roofing installation costs. Choosing a lighter material than your current roofing material can prevent you from having to shell out too much for a replacement. The best lightweight options are asphalt shingles and metal roofing. These materials are durable, so you won’t need to worry about further work for some time.



Your roof must be able to stand up to the elements. Durability should be one of your most important considerations when choosing a material. The best material choice depends mostly on where you live in the country. Strong winds, extreme temperatures, insect infestations, torrential downpours, and risk of fire are possible anywhere in the United States.

Homeowners should opt for a roofing system that can tolerate all kinds of weather but is also optimal for the unique climate challenges of their region. The best performing materials are tiles made from clay and concrete along with metal roofing.



Because roofs are exposed to the elements, they will wear down over the years. Winds will tear shingles off, and animals can get in and cause damage. Flashing can go missing, and tiles can break. All these issues will need to be promptly remedied to protect your roof and your home.

You should periodically check your roof to see if it requires any repairs, especially after storms. Expect to spend money on maintaining your roof throughout the years. You can shave off some of the costs by choosing a low-maintenance roof. Metal roofs are a winner here, along with asphalt shingles. Both choices can stand up to the elements and remain functional while still being a highly attractive roofing material to set off your home.


Energy Efficiency

Your home’s roof directly impacts how energy-efficient your home is. To keep heating and cooling costs low, you’ll want a highly reflective roofing material. Also, consider how well ventilated your roof is.

Certain materials like ceramic or clay tiles can also provide an extra layer of insulation through the air pocket they create. Metal roofing solutions are an excellent choice for reflectivity, and asphalt shingles are ideal for helping your attic stay cool.

How To Winterize Your Roof

Your roof is all that stands between you and an icy winter chill. It’s exposed to Mother Nature’s worst, and that affects more than just your internal climate. Ice-cracked gutters and HVAC inefficiency can cost you precious funds, so winterizing your roof will not only keep you cozy, but it will save you money as well. Your strategy should include:


Fixing Weak Spots

Your roofing system is only as effective as its weakest points. The elements will exploit any route they can find into your house, so your winterization plan will need to identify loose or worn shingles. Pests are just as destructive, so any signs of intrusion must be dealt with before a minor invasion becomes a permanent infestation. If you have a tile roof, we’ll perform a manual inspection for visible damage, both outside and in.


Cutting Back Tree Branches

Even the smallest of limbs can do lasting damage to your shingles. They can cause dents upon impact and put your roof under more pressure than it can withstand. When healthy limbs are torn down by the wind and rain, they can cause even more destruction, so this stage of your strategy will include all branches small and large, old and young.



Roofs and gutters are prone to algae and mold, which, in turn, produce toxins and allergens when they spread to your interior. As the temperature drops, that growth can make its way through your roof and into your shingles, where algae sets down roots. Debris’ effect on your gutters is just as drastic. Blockages allow water to pool, causing bulges and ice dams. That can lead to cracks in freezing temperatures, which can expose your roofing. Your gutters also preserve your insulation and foundation. When they aren’t intact, both can slowly disintegrate, ultimately setting your entire house off-center. Your gutters must be cleared before the first snow of the season.


Checking Attic Insulation

One of Mother Nature’s easiest routes into your home is through your attic. This space forms a barrier between your roof and the rest of your home, so insulation failures can wear heavily on your HVAC system. It’s almost impossible to keep your home warm when your attic insulation isn’t doing its job correctly, so when we winterize, we make sure everything is functioning as it should. Attic insulation is prone to moisture and mold, so we’ll remove damp materials before ensuring that your loose-fill materials are distributed well. Then we’ll add or replace insulation to fill the gaps. This is one of the easiest ways to cut your utility bills, so it’s important to reach ENERGY STAR’s recommended R-levels for the Mid-Atlantic region.


Roof Inspection

Roofing deaths account for almost 100 of the 5,250 annual work-related fatalities, so doing your own inspections is a serious hazard. If you’re an avid handyman, it’s tempting to fetch a ladder and spend the morning checking tiles, but it only takes one misstep to create a medical crisis. Even professionals keep roof walking to a minimum, but visual inspections remain the only way to track damage accurately. If you haven’t had a roof inspection in the last year, it’s time to schedule one. Your roof should be inspected a minimum of twice a year, ideally before spring and fall.

  • Joist – The structure underneath a flat roof that holds the sheathing.
  • Rafter – A slanted structural piece on which sheathing is nailed.
  • Rake – A gabled roof’s slanting edge that extends past the house.
  • Ridge – The top horizontal line that connects to sloped planes, typically at the top of the roof.
  • Sheathing – Sheathing is nailed to the rafters, and shingles or tiles are secured to it to finish the roof.
  • Shingle Flashing – This type of flashing sits under the shingle and is bent to the edge of the wall or chimney to prevent leaks.
  • Slope – The slope, which is also called the pitch, is the incline of the roof measured in rise per 12 inches of horizontal distance.
  • Soffit – These boards sit on the bottom side of the roof to enclose the part that hangs over the edge of the house.
  • Square – A square is equal to one hundred square feet of the roof.
  • Underlayment – This material sits on top of the sheathing and beneath the shingles.
  • Valley – This is an angle where two sections of the roof come together at less than 180 degrees.
