Nearly five decades of roofing experience taught us one thing about homeowners: nobody should have to Google their own contractor’s proposal. This glossary covers the terms, materials, and concepts that come up most often across every stage of a roofing project — from the first inspection to the final warranty. Written in plain language, organized for easy reference, and updated regularly based on the real questions we hear from property owners across eight states.
