When you're building new in Downey, the roof is one of the most important decisions you'll make. It protects everything underneath it for the next 30-50 years. Downey Roofing & Maintenance helps you choose the right material, designs proper ventilation, and installs it to manufacturer specifications.
We install to manufacturer specifications and local Downey building codes. That means proper underlayment per ASTM standards, ice and water shield at eaves and valleys, correct nailing patterns, and ventilation sized to the space. Every component documented for your warranty registration and building inspection.
Our New Roof Installation Process
Plan Review & 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.
Preparation
All materials verified against your approved proposal. Color, brand, quantity, everything double-checked before install day. No substitutions without your approval.
Expert 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.
