Roofing Installation & Replacement

The roof over your head is the single more important protective element of your Olney home. When you choose Certified Inc. for your roof installation, you will be working with roofing specialists with years of experience who can answer any question you might have throughout the installation process. We offer the following types of roofs:

If your roof is old and leaking, we will work with you to determine the best roof replacement options for your home or building. We will create a detailed analysis of your current roof to determine the best replacement method. We’ve seen it all when it comes to weather damage in Maryland, so we can handle anything!


Gutters are an essential protective element  to prevent rain damage on your home or building. They do so by directing rainfall away from the core of the building, which also keeps your foundation protected. Gutters typically last at least a decade, but depending on the material and level of maintenance, they will eventually need to be replaced. Certified Inc. installs the follow types of gutters:

  • 6” aluminum
  • 6″ copper
  • 5″ aluminum
  • 5″ copper
  • Half round

If your gutters clog or leak frequently, it’s time for them to be replaced! Let Certified Inc. help keep you protected with a new set of gutters.


Windows provide exterior aesthetic enhancement while providing important natural light to the interior of your Olney home or building. They can also help save on energy costs! Vinyl windows are a great option because they are low-cost and low maintenance, while also boasting high durability and energy efficiency. They are naturally insulating, so you won’t lose your heat to draftiness. Certified Inc. installs Atrium and Simonton brand windows so no matter which you choose, you know you will be installing a quality product with quality service.


Trim might be purely aesthetic, but it can provide an extra zest or unique feel for your home or building. Trim elements include windows, shutters, fascias, and more. It helps to keep your building’s exterior looking fresh and well-kept. If it is damaged or rotting, the rot could spread to other areas and create further problems. If you need any or all of your trim replaced, Certified Inc. is the team to call to get your exterior spruced up.


Siding offers structural integrity and can enhance your energy efficiency. it also boosts curb appeal. Siding lasts a long time but eventually wears down from natural causes. If your siding is damaged, loose, or discolored, a replacement may be in your future. We install the following types of siding:

  • Vinyl siding
  • HardiePlank siding
  • Cedar siding

If your siding is damaged or rotting, Certified Inc. can help protect your home AND make it beautiful with new siding!
