Our New Roof Installation Process
Design Consultation
We analyze your plans for pitch, square footage, ventilation needs, and code compliance. You get a detailed proposal with material specs, timeline, and fixed pricing before any work begins.
Pre-Installation Setup
Materials delivered and staged on-site the day before installation. Shingle pallets, underlayment rolls, flashing stock, ridge vent, and fasteners, everything confirmed against the project spec sheet.
Certified Installation
From underlayment to ridge cap, every layer installed in the correct sequence by certified crews. A project manager is on-site for new construction installs to ensure quality at every stage.
Final Inspection
After installation: quality inspection, building department sign-off, manufacturer warranty registration, and cleanup. Your new roof is warranted from the day it passes inspection.
