Our New Roof Installation Process

1

Plan Review & Consultation

We review your building plans, discuss material options, and calculate ventilation requirements. Roof pitch, attic space, local code amendments, and your aesthetic preferences all factor into the recommendation.

2

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.

3

Expert Installation

Installation follows IRC building code and manufacturer requirements. Proper overlap, correct fastener patterns, sealed penetrations, and balanced ventilation. Our crews are factory-trained and know the installation manuals by heart.

4

Inspection & Warranty

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.
