Definitely worth it. by Greg Thomas on 10/29/2025 A tree branch damaged my roof during a windy night. NorthStar Roofing arrived early next morning and fixed everything quickly. They even cleaned the debris. I couldn’t ask for better service.

Thank you! by Rochelle Rosales on 6/24/2025 Our garden house roof had a minor puncture from a fallen branch. They patched it cleanly, sealed edges, and inspected the whole roof for hidden damage. Looks good as new. Appreciate the honest service.

Thankful for the tidy work. by melanyd on 6/24/2025 Our back porch always dripped at the gutter end cap. They removed the cap, resealed it properly, and adjusted the slope so water flows out fully. No more drips on our chairs! Thankful for the tidy work.
