Residential Roofers

The roof is perhaps the single most important protective element of any home. When you choose Certified Inc. for your roof installation, you receive a detailed analysis of your current roof and expert roofing specialists who can answer any question you might have throughout the installation process. We offer the following types of roofs:

  • Asphalt
  • Flat
  • Cedar Shake
  • Synthetic Slate

If you are dealing with a dilapidated, old roof, we will work with you to determine the best roof replacement options for your home. We’ve seen it all when it comes to weather damage in Maryland, Virginia, and Washington, DC, so we’re ready for anything!

Residential Gutter Services

Gutters are an essential protective element for all homes. They protect your roof, siding, and foundation by controlling the flow of rainfall. Gutters typically last decades, but depending on the material and level of maintenance, they will eventually need to be replaced. Certified Inc. installs the following 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 your home protected with a new set of gutters.

Residential Window Replacement

Windows are a little-known way to make serious cuts on energy costs while also improving your Maryland home’s exterior and adding valuable natural light to the interior. 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 is an important aesthetic element that adds beauty and value to the exterior of your home. Trim elements include:

  • Window and door moldings
  • Shutters
  • Decorative and functional louvers
  • Decorative masonry and stucco work
  • Balustrades
  • Overhanging eaves
  • Surrounds
  • Fascias
  • Cornices
  • Trellises
  • Copper trim
  • Half-timber work

Trim helps to keep your home looking fresh and well-kept. If it is damaged or rotting, it could spread to other parts of your house and create further problems. If you need any or all of your trim replaced, Certified Inc. is the team to call to get your home spruced up.

Residential Siding Contractors

Siding affects not only your home’s structural integrity but also its curb appeal and energy efficiency. Siding typically has a long lifespan, but natural causes can wear it down. 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 blistering, rotting, or loose, Certified Inc. can help protect your home AND make it beautiful with new siding!
