What We Do | O Fallon Roofing & Maintenance Roofing Services
O Fallon Roofing & Maintenance offers a complete range of roofing services in O Fallon and Victoria, Alpha, Brighton, Coffeen, Elizabethtown. Every job gets the same attention. Big or small.
Roof Replacement
We replace roofs. It's what we do more than anything else. Our O Fallon crews average 15-20 complete tear-off and replacements per month. That kind of volume means we've seen every situation: steep pitches, multiple layers, rotted decking, improper ventilation from the last guy. We fix all of it and install a roof system that's warranted for decades.

Most roof leaks in O Fallon come from one of five places: pipe boots, step flashing at walls, valley flashing, damaged shingles, or failed seals around skylights. We find the actual source. Not just the drip point in your ceiling. And fix it right. Water travels along rafters and sheathing before it drips, so the leak location and the damage location are often 10 feet apart.

Not all storm damage qualifies for a full replacement. Hail might only damage one slope. Wind might only lift shingles on the windward side. We document exactly what's damaged and let the insurance company make the call. Honest documentation gets claims approved. Inflated claims get denied.

New construction underlayment per IRC R905 and ASTM D226 (felt) or ASTM D6757 (synthetic). Ice barrier per ASTM D1970 required at eaves in climate zones with average January temperature below 25°F. We install ice and water shield regardless. It's cheap insurance against ice dams and wind-driven rain. Drip edge per IRC R905.2.8.5 on eave and rake edges. Proper starter strip with factory sealant for wind resistance from day one.

Standing seam metal is the longest-lasting residential roofing material you can install. 40-60 year lifespan, virtually zero maintenance, and it sheds hail and debris better than any shingle. Our O Fallon metal crews install residential and commercial standing seam, corrugated, and metal shingle profiles.

Shingle color matters more than you think. Dark shingles absorb heat. Great for cold Illinois winters, harder on cooling bills in summer. Lighter colors reflect heat. Algae-resistant granules prevent black streaking. We bring shingle samples to your O Fallon home so you can see them against your siding and trim.

EPDM (rubber roofing) has a 50+ year track record as a flat roofing membrane. We install fully adhered EPDM with taped or glued seams over polyiso insulation. It's a great option for O Fallon building owners who want proven performance at a lower cost than TPO or PVC.
Get a Free Quote →Commercial Roofing
Your commercial roof has HVAC units, exhaust fans, plumbing vents, and satellite dishes punching through it. Every penetration is a potential leak point. We install prefabricated curbs, custom-welded flashings, and pitch pans that handle foot traffic and thermal cycling without failing.

Clogged gutters cause fascia rot, soffit damage, and foundation erosion from concentrated water runoff. That's not a marketing scare tactic. We see the damage on every other gutter replacement in O Fallon. Properly sized gutters with adequate downspout capacity move water away from the house. We calculate capacity using rainfall intensity data for O Fallon: roof area x pitch factor x rainfall rate in inches per hour. Standard 5" K-style handles 5,520 square feet of effective roof area.

Roof inspections are free for O Fallon homeowners. No strings, no obligation to hire us for repairs. If your roof is fine, we say so. If it needs attention, you get an honest assessment of what's going on and what it'll cost to fix.

Storm, wind, hail, or fallen tree. We've handled every kind of roofing emergency in O Fallon. First priority is always preventing further water damage to your interior. Second priority is documentation for insurance. Third is the permanent fix.
