New Roof Installation in Washington County, PA

Washington County keeps building, from new subdivisions in Peters Township and North Strabane to additions on older homes in Washington and Canonsburg. A new structure needs a roof that is installed right from the deck up, because that is the one time every layer is easy to reach.

Rail Roofing Group installs roofs on new homes, additions, garages and commercial buildings. We work with homeowners, builders and general contractors.

What goes into a new roof

• Inspection of the roof deck before anything is installed
• Ice and water protection at eaves, valleys and other areas where water collects
• Underlayment over the full deck
• Drip edge at eaves and rakes
• Flashing at every wall, chimney, valley and penetration
• Ventilation planned so the attic stays dry
• Shingles installed to the manufacturer's instructions

Tying an addition into an existing roof

The place where a new roof meets an old one is where additions most often leak. The new section has to be flashed into the existing roof and wall, the shingle lines have to work with each other, and the valley between them has to carry water off rather than into the seam.

We look at the existing roof as part of the estimate, so you know whether it is in good enough shape to tie into or whether part of it should be redone at the same time.

Working with your build schedule

On new construction the roof is usually what gets the building dried in, so timing matters to everyone who comes after. Tell us where the project stands and when the framing will be ready, and we plan the installation around it. For larger commercial projects a team member scopes the job in person.

Roof Installation: common questions

Do you work with builders and general contractors?

Yes. We install roofs for homeowners building on their own and for builders and general contractors managing a project.

Can you add a roof to an addition on an older house?

Yes. We tie the new roof into the existing one and check the condition of the old roof during the estimate, so the seam between them does not become the next leak.

Do you install roofs on commercial buildings?

Yes, residential and commercial. Large commercial projects are scoped in person by a member of our team before we quote.
