Roofing New Construction
On a new home, new construction roofing means we coordinate with the builder on deck inspection, flashing at walls and windows, ventilation and the order of trades. Starting with a fresh deck lets us install underlayment, leak barrier and edge metal exactly to specification. We also confirm that bath fans, kitchen hoods and dryer vents exit through the roof or walls with proper flashing rather than ending in the attic, a detail that is easy to overlook while a house is going up. Our shingle installation in Oxford page covers product choices for new homes and replacements alike.
Tying an Addition Into an Existing Roof
The joint between old and new roofs is where many additions leak. We weave or flash the new section into the existing roof, extend leak barrier across the connection and match shingle color as closely as possible. When the existing roof is near the end of its life, we may suggest replacing both at once for a uniform look and a single warranty.
- Matching pitch and overhangs so the addition looks original.
- Valley and wall flashing where new meets old.
- Ventilation planned for both attic spaces.
Porches, Patios and Outbuildings
Covered porches often have lower roof pitches that need a membrane or metal instead of shingles. Detached garages, workshops and pavilions may suit exposed-fastener metal. If you are planning a covered porch addition, we can handle the framing and roofing under one plan.
Working Close to Home
Because our office is in Oxford, we can visit during planning, check in during construction and come back easily after the job if questions arise. Learn about our full range of local roofing services on the Oxford roofing contractor page.
Common Questions
Can you match new shingles to my existing roof on an addition?
We get as close as possible, but weathered shingles rarely match new ones perfectly. If the difference would be noticeable, we discuss replacing the whole roof for a uniform finish.
Do you work with builders on new homes in Oxford?
Yes. We coordinate schedules and details with builders and homeowners on new construction.
What roofing works on a low-slope porch?
Below the minimum pitch for shingles, we recommend a membrane or metal roof. We measure the slope and suggest the right system.
Is Tekton Exteriors licensed and insured?
Yes. We are a licensed and insured exterior contractor based in Oxford and can provide proof of coverage.
