New construction means we start with a clean deck and build the roofing system properly from the first layer. Cosmopolis Roofing & Maintenance has installed new roofs on hundreds of new builds across Cosmopolis, from custom homes to spec builds, from room additions to detached structures.
Our New Roof Installation Process
Plan Review & 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
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
We schedule the building inspection and walk the roof with the inspector. Your manufacturer warranty gets registered the same day the roof passes inspection. You receive warranty paperwork within a week.

Why Choose Cosmopolis Roofing & Maintenance for New Roof Installation?
Builder Coordination
We work directly with your GC on scheduling, staging, and inspections. On-time delivery and clean work that doesn't slow down the rest of the build.
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.
Code Compliance
Every installation meets IRC building code and local Cosmopolis amendments. Proper underlayment, ice barrier, and fastener patterns documented for inspection.
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 WA climate.
