Building a new home or adding on to your existing one? Cohagen 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 Cohagen build.
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.
Our New Roof Installation Process
Project Planning
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
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.
Expert 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 Cohagen office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.
