A roof on a new structure is the chance to get every layer right without working around old problems.
Call (717) 802 8110New Roof Installation for Mechanicsburg homes
New roof installation covers roofs on additions, sunrooms, detached garages, and other new structures. With no old roof to remove, the focus is on building a complete, well detailed system from the sheathing up.
Where an addition meets an existing house, the connection is a common trouble spot. Tying the new roof into the old one cleanly is one of the most important parts of the job.
Projects that need a new roof
- A home addition or bump out under construction
- A new detached garage, shed, or workshop
- A covered porch or patio roof
- A dormer added to create living space in an attic
The process
How new roof installation works, step by step
- 1
Plan early
Roof slope, overhangs, and ventilation are easier to get right before framing is finished.
- 2
Check the deck
The sheathing should be sound and flat before roofing begins.
- 3
Build the layers
Underlayment, metal edges, flashing, and the roofing material go on in order.
- 4
Tie in and finish
Transitions to the existing house are flashed and the site is cleaned up.
Matching an addition to the main roof
Most homeowners want an addition to look like it was always there. That means matching shingle style and color where possible and lining up eaves and ridges thoughtfully.
When the main roof is old, a perfect match may not be realistic. In that case it can make sense to think about the whole house, now or later.
Common questions
Should a roofer be consulted before framing?
It can help. A short conversation about slope, overhangs, and ventilation can prevent problems that are hard to correct once the roof is built.
Can a low slope addition use shingles?
Shingles need a minimum slope to shed water. Below that, a flat roof membrane or certain metal systems are the usual choice.
