Building a new home or adding on to your existing one? Johnston 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 Johnston build.
Our New Roof Installation Process
Design Consultation
Meet with our Johnston 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.
Preparation
All materials verified against your approved proposal. Color, brand, quantity, everything double-checked before install day. No substitutions without your approval.
Professional 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.
Final Inspection
Final quality check against manufacturer installation requirements. Building inspection coordinated through our Johnston office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.

Why Choose Johnston Roofing & Maintenance for New Roof Installation?
Material Selection Guidance
Shingles, metal, flat systems. We install all of them and help you choose based on your budget, design, and the demands of IA climate.
New Construction Specialists
We install new roofs on new builds every week. Our Johnston 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.

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