Building a new home or adding on to your existing one? Diagonal 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 Diagonal build.

We install to manufacturer specifications and local Diagonal 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

1

Project Planning

Meet with our Diagonal 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

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.

3

Professional 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.

4

Warranty Registration

We schedule the building inspection and walk the roof with the inspector. Your manufacturer warranty gets registered the same day the roof passes inspection. You receive warranty paperwork within a week.

Why Choose Diagonal Roofing & Maintenance for New Roof Installation?

Code Compliance

Every installation meets IRC building code and local Diagonal amendments. Proper underlayment, ice barrier, and fastener patterns documented for inspection.

New Construction Specialists

We install new roofs on new builds every week. Our Diagonal crews know the pace, the coordination, and the quality standards that new construction demands.

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.

Full Manufacturer Warranty

Factory-certified installation means your new roof warranty is fully backed from day one. No gaps, no exclusions from improper installation.

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.
