O'Fallon Roofing Services You Can Count On

Roof Replacement

When a roof is beyond repair, we provide complete replacements using high-quality materials built to withstand Missouri's unpredictable weather. This is one of the most requested services from homeowners searching for a reliable O'Fallon roofing contractor.

Roof Repairs

Some roofs need targeted repairs instead of a full replacement. We address leaks, missing shingles, and structural trouble with lasting fixes. If repairs aren't the right call, we'll guide you toward a full replacement.

Shingles

We install durable, attractive shingles in various colors and styles as part of our O'Fallon roofing. Our shingle roofs not only look great but offer strong protection year-round.

Metal Roofing

A smart choice for homeowners looking for durability and energy efficiency. Metal roofs handle storms, sun, and snow without wearing down.

Commercial Flat Roofing

We also handle low-slope and flat roofing systems for business properties. Our team installs and replaces long-lasting commercial roofs that protect your investment.

Storm and Hail Damage

Storms can be brutal in O'Fallon. We specialize in full replacements after storm and hail damage, guiding you through repairs and even insurance claims when needed.

Gutters

A good roofing system needs good gutters. We install seamless, clog-resistant systems that direct water away from your foundation.

Siding

Fresh siding boosts curb appeal and shields your home from wind, rain, and temperature changes. We offer several styles to match your home's design.

Ben, the Sales Rep was great, providing a free estimate on my roof for damage that occurred from hail in May, 2024. Ben was not pushy and was straight forward in what he and BrandonJ would do in getting my roof replaced that had resulted in 85% damage. Ben met with my insurance adjuster who was on the roof less than 10 minutes. Ben took pictures of all damage prior to meeting with adjuster and showed me everything that was damaged. Adjuster agreed the damage was extensive and insurance gave me a new roof and chimney cap. Installation was flawless, and cleanup impeccable. I highly recommend BrandonJ, and ask for Ben.

Damon was very professional and helpful through the entire process. Couldn't ask for better after storm damages. Wade with the siding crew was awesome as well — very timely and professional with how busy they have been.

Robert Cape Jan 13, 2026

Everyone was so nice! Great to work with. Handled everything for me with the insurance. They definitely go above and beyond. Project manager Wade was awesome! Always got right back to me and handled everything promptly. Left my house and yard in tip top shape. Highly recommend!

Tracy Niznik Perkins Jan 13, 2026

Worked with Billy and Dylan to replace my roof. They were very professional and worked with me to get the exact color and style for my house. Worked very well with my insurance company. Very happy with the results.

Kay Griffin Jan 10, 2026

We had our roof replaced, a minor gutter repair, and siding on the west side of our home replaced. The folks at Brandon J were friendly and did quality work. If a problem came up (and we only had one) they took care of it and made it right. Would certainly recommend them to others.

Tom Bander Jan 9, 2026

Brandon J did an excellent job replacing our roof, gutters, and siding after storm damage. Our project managers were communicative and transparent especially in the current challenging sourcing market. They also go to bat for you in dealing with insurance companies. Highly recommend!

Thomas Cannon Jan 8, 2026

Dylan came out to inspect my roofing and fascia. He communicated well, explained what caused my issue, how he could help, and was kind and very professional.
