Flat Roof Options — Simplified
Flat Roof Options: Compare Five Plans
Compare the owner-supplied roof plans by materials, proposed warranty and included services. Confirm the approved assembly, current price, warranty eligibility, inspection term and start date in your written proposal. A product rating is not a guarantee for every roof or storm.
Materials, tradeoffs, warranties & price
Compare the complete membrane system, total thickness, liquid-flashed detailing, warranty coverage, included service protections and exact price change from the Protector base.
