When you're building new in Greenland, the roof is one of the most important decisions you'll make. It protects everything underneath it for the next 30-50 years. Greenland Roofing & Maintenance helps you choose the right material, designs proper ventilation, and installs it to manufacturer specifications.

Our New Roof Installation Process

1

Design Consultation

Meet with our Greenland 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.

2

Preparation

All materials verified against your approved proposal. Color, brand, quantity, everything double-checked before install day. No substitutions without your approval.

3

Certified Installation

Our Greenland 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.

4

Final Inspection

Final quality check against manufacturer installation requirements. Building inspection coordinated through our Greenland office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.

New Roof Installation FAQ

Critical. Improper ventilation causes premature shingle aging, ice dams in cold weather, and excessive attic heat in summer. We calculate intake and exhaust per code requirements. Balanced ventilation extends roof life and reduces energy costs.

Synthetic underlayment meeting ASTM D6757 across the full deck. Ice and water shield per ASTM D1970 at eaves, valleys, and all penetrations. These layers are critical. They're your last line of defense if the shingles fail.

One to three days for most residential projects. Standard homes are typically done in one day. Larger custom builds or complex multi-material roofs take two to three days. We coordinate timing with your GC.
