CertainTeed
Reviewers report mixed experiences with General Roofing. Several customers describe positive interactions, praising specific team members like Shane, Luis Gomez, and Juan Gomez for thorough work, responsiveness, and going above and beyond expectations. Some reviewers report satisfaction with roof repairs and maintenance that have held up through severe weather, and note the company's long family history. However, other reviewers express significant dissatisfaction, describing failed repairs that leaked immediately after completion, unresolved issues with workmanship that deteriorated within years, and difficulty obtaining follow-up service or communication. One reviewer reports being given "the run around" with no return phone calls after promised repairs. The company has responded to some negative reviews, attributing issues to maintenance requirements or disputed service scope, though some reviewers remain unconvinced and report hiring other contractors to redo work.
