Putting off a minor roof or significant roof repair in almost every case leads to property damage that could have been avoided. Left unattended damage to ceilings, walls, insulation, structural components, and more is all but a forgone conclusion. 

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.
