35 Roofing Companies in Nampa, Idaho

Of the 12 companies we track in Nampa, 3 have an active contractor license located in public records, 9 are registered business entities, and 6 operate from a commercial rather than residential address. Idaho issues roofing-contractor licensing at the state level, so an active state license is the baseline credential to confirm before hiring. A company not appearing with a license here isn’t proof it’s unlicensed - some jurisdictions don’t publish - so verify directly, and always confirm liability and workers’ comp insurance before work starts.

The roofers we track in Nampa have been in business a median of 8 years, by their state formation date. The longest-operating is Western Roofing, in business since 1990 (36 years); 1 was formed less than two years ago. A verifiable formation date and registered agent on file is one of the clearest lines between an established local company and a transient operator.

Roofing demand in Nampa is driven less by storms than by snow load, ice dams, and freeze-thaw cycling. Ice-and-water shield at the eaves plus strong attic ventilation are the key defenses against ice dams. Of the 12 companies we track, 6 hold a manufacturer certification for these systems.

6 of the 12 roofers we track in Nampa hold at least one manufacturer certification (GAF, Owens Corning, CertainTeed, TAMKO, IKO, Malarkey). The most common here is CertainTeed, held by 3 companies - versus 56% certified across Idaho. Certification means the manufacturer vetted the contractor and lets them back your roof with stronger, longer material-and-labor warranties. Not required to install a roof, but a real signal of training and standing.

Across the 12 companies we track in Nampa, the average rating is 4.7★, combining Google, BBB, and Yelp. 10 appear on more than one platform and 9 have owners who actively respond to reviews. Look for steady, recent, multi-source ratings over a handful of old five-star reviews on one site - any single platform can be cherry-picked.

Roofing is a high-fall-risk trade, so safety history matters. Of the 12 companies we track in Nampa, 1 has at least one federal OSHA violation on record in the past 10 years, and 11 have none. We show any recorded violation - citation, severity, and penalty - on each profile. A clean record isn’t a guarantee, but repeated serious violations are a real red flag.
