A new roof installation is your chance to get everything right from the start. No compromises, no working around someone else's mistakes. Mantee Roofing & Maintenance installs new roofing systems on new homes, additions, detached garages, carports, and covered patios throughout Mantee.
Whether it's GAF Timberline HDZ, Owens Corning Duration, CertainTeed Landmark, or a standing seam metal system, our Mantee crews install it the way the manufacturer requires. Factory-certified installation means your warranty is fully backed from day one.
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.
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.
Warranty Registration
Final quality check against manufacturer installation requirements. Building inspection coordinated through our Mantee office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.
