Brennan Roofing in Michigan
Brennan Roofing specialists handle roof repair and full roof replacement for homeowners across Michigan under one fixed rule: the price goes on paper before any work starts, and that number does not move at the door. We’re part of the Garrison Partners family, which means every job runs to The Garrison Standard. Michigan weather punishes roofs hard. Ice dams in February. Wind-driven rain off the lakes. Freeze-thaw cycles that work shingles loose by March. Homeowners here have learned the hard way that a roofer who shows up late, or not at all, costs more than any bid. We’re built for people who are done with that.
Why Michigan Homeowners Choose Brennan Roofing
Michigan homeowners call us because they’ve been burned before. A crew no-shows. The price jumps once the old shingles come off. The job gets done, but nails end up in the flower bed and nobody answers the phone afterward. We run a different operation. Every Brennan technician is background-checked and uniformed, so you know exactly who is on your roof. Every job carries the 365-Day Done Right Promise: if a repair or installation fails within a full year, we come back and make it right at no charge. That’s not a verbal promise. It’s written down. We install materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and we explain the real differences between them in plain words so you choose with confidence, not pressure. The Garrison Code governs the whole thing: show up inside the window we gave, put the price in writing before any work starts, do it by the book the first time, leave the site clean and squared away, and stand behind the work for a full year. That’s the standard on every Brennan job in Michigan, no exceptions.
