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.

Posted on Trina CornellTrustindex verifies that the original source of the review is Google. We had severe hail damage to our roof and siding from the spring storms of 2025. Gallagher Bros. Construction was recommended to us as a great company to use. We truly had a great experience working with Rex and the work crews that came to replace our roof and siding. Both projects, with the roof in November and the siding in February, were completed within the span of two days. Both jobs were done extremely well! The best part about working with Gallagher is their work with the insurance companies. They worked on our behalf to help us get the maximum amount of money we needed from our insurance to pay for the work completed. Everything was handled professionally from start to finish - and we could not be happier with the work completed! We will definitely be recommending Gallagher Bros. Construction to anyone that needs their services - and we would love to work with them again if the need arises!Posted on Joe ChickTrustindex verifies that the original source of the review is Google.
