New construction means we start with a clean deck and build the roofing system properly from the first layer. Portage Roofing & Maintenance has installed new roofs on hundreds of new builds across Portage, from custom homes to spec builds, from room additions to detached structures.
Our New Roof Installation Process
Design Consultation
We analyze your plans for pitch, square footage, ventilation needs, and code compliance. You get a detailed proposal with material specs, timeline, and fixed pricing before any work begins.
Preparation
All materials verified against your approved proposal. Color, brand, quantity, everything double-checked before install day. No substitutions without your approval.
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.
Warranty Registration
Final quality check against manufacturer installation requirements. Building inspection coordinated through our Portage office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.

About Our Portage New Roof Installation Services
Proper ventilation is the most overlooked element in new roof installation. We calculate intake and exhaust requirements per IRC R806 based on your attic square footage. Balanced ventilation (soffit intake matched to ridge exhaust) keeps your attic cooler in summer and drier in winter, extending roof life and reducing energy costs.
Call (877) 349-1553 for a free consultation on your new build. We review plans, recommend materials, calculate ventilation, and provide a detailed proposal. Whether you're building a custom home or adding a 200 square foot covered patio, Portage Roofing & Maintenance has the experience to do it right.
