O Fallon Roofing Experts

Replacing your roof isn't just about shingles. We install ice and water shield in the valleys and along eaves, synthetic underlayment across the whole deck, new drip edge on rake and eave, starter strip, and ridge vent. That's how a roof lasts 30 years in Illinois.

Missing shingles cause water intrusion through the exposed underlayment and decking. We don't just replace the missing shingle. We check the deck for moisture damage with a Protimeter pin meter, replace any compromised underlayment, and weave new CertainTeed Landmark shingles into the existing pattern.

Wind damage doesn't always look obvious from the ground. Lifted shingles, broken seals, exposed nail heads. You can't see any of that without getting on the roof. Our O Fallon inspector does a full 27-point inspection, free of charge.

Atlas Pinnacle Pristine shingles with Scotchgard algae protection. Ideal for Illinois humidity. We also install Tamko Heritage laminated shingles for budget-conscious builds and Malarkey Vista AR with Flexor SBS polymer-modified asphalt for high-wind zones. Your installer should match your material choice to your climate, not just your budget.

Standing seam metal roofing with Kynar 500/Hylar 5000 PVDF finish. The coating that keeps color for 40+ years without fading or chalking. We install Sheffield Metals and McElroy Metal panels in 24-gauge Galvalume steel with concealed Z-clips. UL 2218 Class 4 impact resistance. UL 790 Class A fire rating. Wind uplift tested to ASTM E1592. The only roof you'll ever need in O Fallon.

Asphalt shingle roofing is the most common and cost-effective roofing system in O Fallon. Our crews install 15-20 shingle roofs a month. We know the product inside and out. Nailing patterns, exposure measurements, hip and ridge details.

A flat roof that's ponding water is a flat roof with a problem. We install tapered insulation systems to create positive drainage to your scuppers or interior drains. No more standing water after rain.

Our 27-point roof inspection covers: shingle condition, granule loss, nail pops, lifting tabs, ridge cap integrity, valley flashing, step flashing at walls, drip edge, pipe boot seals, vent function, soffit ventilation, gutter pitch, downspout capacity, fascia condition, decking (from attic if accessible), and visible signs of moisture in the attic. Written report with photos emailed same day.

Most emergency roof repairs in O Fallon are storm-related. High winds rip off ridge caps and shingles. Fallen limbs puncture the decking. We respond fast, tarp the damage, and coordinate the permanent fix. Including insurance paperwork if applicable.

We install, replace, and repair skylights in O Fallon homes. Fogged glass, cracked frames, persistent leaks around old skylights. We fix it all. Sometimes replacing a 20-year-old skylight is cheaper than trying to repair it.
