Building a new home or adding on to your existing one? San Gabriel Roofing & Maintenance handles new roof installation from decking to ridge cap. We work with your general contractor or architect to coordinate scheduling, material selection, and code compliance for your San Gabriel build.

Our New Roof Installation Process
Plan Review & Consultation
Meet with our San Gabriel project coordinator to select materials, review color options, and confirm the installation scope. We work with your GC or architect to ensure the roof spec meets the overall building design.
Material Delivery & Staging
We coordinate delivery timing with your GC so materials don't sit exposed longer than necessary. Our staging crew organizes everything on the roof deck for efficient installation the next morning.
Certified Installation
Our San Gabriel crew installs every layer to manufacturer specifications: underlayment, ice and water shield, drip edge, starter strip, field material, hip and ridge caps, and ventilation. Every fastener placed per the manufacturer nailing schedule.
Warranty Registration
After installation: quality inspection, building department sign-off, manufacturer warranty registration, and cleanup. Your new roof is warranted from the day it passes inspection.
