After an in-home visit and the project quote is accepted, most roofs are installed within 1-2 weeks. The installation of your roof generally takes 1 day.

A Leak-Proof Roof

Your roof is more than just shingles. We carefully inspect and install the entire roofing system that exceeds local building code to keep your home insulated, beautiful, and secure.

Each part of a roofing system is designed to bolster a weak point of your roofing architecture, reinforcing areas which are susceptible to leaking.

01
Wood Deck

A solid wooden base is needed for nailing and creating a strong foundation for the layers of your roof. Removing old roofing materials allows us to address problems such as rotten wood or cracked boards, leaving a strong deck to install your new roof onto.

02
Flashing

Flashing is used to seal and protect joints in a building from water penetration by directing the flow of water away from vulnerable areas. Varieties of flashing which may be used include step, apron, and counter flashing.

03
Leak Barrier

Ice & Water Shield is a 100% watertight membrane that protects your home from extreme weather events that try to drive rain into your home. It is installed at the eaves, valleys, chimney, vents, and skylights, ensuring your roof is completely sealed and protected.

04
Deck Protection

Synthetic underlayment provides an extra layer of protection between your shingles and roof deck. This water resistant layer is lighter and stronger than traditional felt, keeping your roof durable as it wicks moisture away.

05
Drip Edge

Drip edge is an added layer of waterproofing installed around the roof line. This piece of aluminum ensures no damage occurs beneath shingles by sealing and protecting the roof deck from water rollback and driving rains.

06
Starter Shingles

Pre-cut starter strip shingles speed up installation while helping prevent shingle blow-off. These shingles include factory-applied adhesive strips, which ensure enhanced wind resistance and a uniform finish to your roof.

07
Lifetime Shingles

Shingles are vital and the first line of defense in keeping your home protected from the forces of nature. All of our shingles are covered by a Lifetime Warranty, so you can have peace of mind knowing your home is protected.

08
Attic Ventilation

A ridge vent along with ridge cap shingles are installed to help remove excess heat and moisture from your attic. These variables could cause premature aging of your roofing system, but attic ventilation works to prevent this.

Lifetime warranties from the best.

We meet the highest standard in continual training to offer you manufacturer backed warranties. All our roofing projects include a transferrable lifetime warranty.

My husband and I met with Pat Jewell and he was such a pleasure to work with. Very knowledgeable and kind. We felt comfortable with this company.
We are very pleased with the work that Capitol Improvements did and we would highly recommend and use them again in the future.

Seth and install team were organized and project went smoothly. Entire team was responsive and kept in touch throughout the process.
They replaced my roof including skylights in April 2023 and I am very satisfied. Melinda as my first contact was very professional and got me on the schedule quickly.
It was easy to work with Pat to get a quote. We did both a roof on our house and our shed, we also had new gutters put on our den. The crew was very hardworking and efficient.
