Interlock Roofing Guides

The best roofing for your city’s climate

Every climate stress-tests a roof differently — hail on the Prairies, freeze-thaw and ice dams around the Great Lakes, relentless moisture in the Pacific Northwest, salt-driven storms on the Atlantic coast, and wildfire out West. These guides rank the real options for each metro against the threats it actually faces, using Interlock’s live install record, verified GuildQuality reviews, and third-party certification standards.
