Shingle Repair & Replacement
Missing a few shingles after a windstorm? Noticing cracked, curling, or granule-bare shingles? These aren’t just cosmetic issues—exposed areas leave your roof deck vulnerable to water damage and rot.
Gallagher Bros stocks common shingle types and colors, allowing us to make many repairs quickly. When your shingles are discontinued or hard to match, we’ll find the closest option and blend the repair to minimize visible differences.
When to repair vs. replace: If your roof is under 15 years old and damage is localized, repair usually makes sense. If you’re seeing widespread deterioration or your roof is approaching 20+ years, we’ll give you an honest assessment of whether repairs will hold or if replacement is the smarter investment.
Roof Repair FAQs
Should I file an insurance claim for roof damage?
It depends on the damage extent and your deductible. We recommend calling us first for a free inspection. We’ll assess the damage honestly and help you decide whether a claim makes financial sense.
Can you match my existing shingles?
In most cases, yes. We stock common shingle types and have access to a wide range of products. For discontinued shingles, we’ll find the closest match and install repairs to minimize visual differences.
Do you work with all insurance companies?
Yes. We’ve worked with State Farm, Allstate, American Family, Farmers, USAA, and virtually every other major carrier. We know their processes and documentation requirements.
EXCELLENT Based on 663 reviews Posted on Google Austin EverettTrustindex verifies that the original source of the review is Google. Had roof and gutter system including facia and soffit replaced. Thanks to the crews that had to deal with the terrible heat to complete the tasks. Also thanks to Scot Hollrah for his expertise in answering my questions and managing the project to completion.Posted on Google jill steigerTrustindex verifies that the original source of the review is Google. Great experience and workmanship. Highly recommend. Curtis was great to work with. Besides giving my grandma a bid on the roof and gutters, he got a bid for the ceiling damage inside and worked with her insurance company to get it all approved.Posted on Google Joan WidmannTrustindex verifies that the original source of the review is Google.

We used Gallagher Bros for roofing replacement in the past. When it came time to replace our cedar siding we knew we could work with Gallagher Bros Construction. They advocated for us with our insurance company and had the expertise to install LP composite siding rather than vinyl. Bob, Chris, and Carlos were wonderful to work with and always very responsive. They were detail-oriented and several of our neighbors have commented on the high quality of work. We couldn’t be happier with the results.Posted on Google Donna ToedebuschTrustindex verifies that the original source of the review is Google. Great service. Bob was easy to work with.
