New construction means we start with a clean deck and build the roofing system properly from the first layer. Knightsen Roofing & Maintenance has installed new roofs on hundreds of new builds across Knightsen, from custom homes to spec builds, from room additions to detached structures.
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.
Preparation
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.
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.
Inspection & Warranty
Final quality check against manufacturer installation requirements. Building inspection coordinated through our Knightsen office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.
