Get answers to common questions about roofing services in O Fallon, Illinois.
For a standard single-family home in O'Fallon, a full asphalt shingle roof replacement typically ranges from $8,500 to $15,000. The final cost depends heavily on your roof's square footage, pitch, the complexity of the job (like valleys and dormers), and the quality of materials chosen. Illinois' seasonal weather means labor costs can fluctuate, and it's wise to get 3-4 detailed, written estimates from local, licensed contractors for an accurate price.
The ideal windows are late spring (May-June) and early fall (September-October). These periods typically offer the mild, dry weather needed for proper installation and material adhesion. Summers can be hot and humid, which can make shingles overly pliable, while late fall and winter bring unpredictable rain, snow, and cold temperatures that can delay work and affect installation quality.
Yes, the City of O'Fallon requires a building permit for a full roof replacement. A licensed roofing contractor will typically pull this permit, which ensures the work complies with the 2021 International Residential Code (IRC) adopted by Illinois and O'Fallon's local amendments. This includes requirements for proper underlayment and wind resistance, which is crucial given our region's potential for severe storms and high winds.
Always verify an Illinois roofing license, local liability insurance, and worker's compensation. Check for a physical local address and strong reviews on platforms like Google and the Better Business Bureau. Ask for local references in O'Fallon or nearby neighborhoods to see past work. A reputable contractor will provide a detailed, written contract outlining materials, scope, timeline, and warranty information.
The most frequent issues are wind damage to shingles, ice dam formation in winter, and damage from hail during our spring and summer thunderstorms. Preventative measures include scheduling annual spring and fall inspections, ensuring your attic has proper ventilation to minimize ice dams, and keeping gutters clean. After any major storm, have a professional inspect for granule loss or cracked shingles that aren't always visible from the ground.
