Building a new home or adding on to your existing one? Grand Isle 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 Grand Isle build.
Material options include architectural asphalt shingles, standing seam metal, corrugated metal, and flat membrane systems. Each has different pros, cons, and price points. We help you choose based on your budget, aesthetic preferences, the pitch of your roof, and the climate demands of LA.
Our New Roof Installation Process
Project Planning
Meet with our Grand Isle 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.
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.
Professional Installation
Our Grand Isle 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
Final quality check against manufacturer installation requirements. Building inspection coordinated through our Grand Isle office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.

Why Choose Grand Isle Roofing & Maintenance for New Roof Installation?
Builder Coordination
We work directly with your GC on scheduling, staging, and inspections. On-time delivery and clean work that doesn't slow down the rest of the build.
Full Manufacturer Warranty
Factory-certified installation means your new roof warranty is fully backed from day one. No gaps, no exclusions from improper installation.
Ventilation Design
We calculate intake and exhaust per IRC R806 for every new install. Balanced ventilation extends roof life and cuts energy costs. Most contractors skip this step.
