Building a new home or adding on to your existing one? Grinnell 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 Grinnell build.
Our New Roof Installation Process
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.
Pre-Installation Setup
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.
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.
Final Inspection
Final quality check against manufacturer installation requirements. Building inspection coordinated through our Grinnell office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.
