Roof Repair & Replacement in Monticello, IL

"Hail punched through half our shingles last spring. Dahlgren Roofing & Maintenance handled the entire insurance claim — met the adjuster, filed the supplement, and we paid nothing out of pocket besides the deductible."

"We went with the Owens Corning Duration shingles in Driftwood. The ridge vent and intake ventilation they installed dropped our attic temperature noticeably. Energy bill went down that first summer."

"I called about a small leak and expected a hard sell on a full replacement. The inspector showed me it was just a cracked pipe boot — $300 repair instead of a $12,000 roof. Honest company."

GAF Master Elite Certified

Only 2% of roofing contractors in the country hold GAF Master Elite certification. That gives Monticello homeowners access to the Golden Pledge warranty: 25 years on workmanship, 50 years on materials. It's the strongest warranty in the industry.
