Frequently Asked Roofing Questions In Decatur, Illinois

Labor Costs

How much does roofing labor cost in Decatur, Illinois compared to nearby areas? In Decatur, roofing labor typically runs about $1.25 to $2.25 per square foot, or $40 to $70 per hour, roughly 5 to 12 percent lower than Champaign and Bloomington, and 15 to 25 percent lower than the Chicago metro. Smaller nearby towns may be marginally cheaper by about 5 percent.

Weather & Climate Considerations

How does Decatur, Illinois's weather affect roof lifespan? Decatur, Illinois averages about 40 inches of rain, about 22 inches of snow, typical winds near 10 mph and strong summer sun around 2,200 hours annually, and Lake Decatur raises summer humidity, so moisture, freeze-thaw, wind uplift and UV accelerate shingle granule loss, ice dams and flashing failures, shortening roof life.
What is the most common cause of roof damage in Decatur, Illinois? In Decatur, Illinois, the most common cause of roof damage is severe spring and summer thunderstorms, especially hail and straight line winds, with occasional tornadoes, heavy wet snow and freeze thaw cycles adding risk, while aging roofs and poor maintenance worsen storm impacts.
What is the best time of year to replace a roof in Decatur, Illinois? In Decatur, Illinois, best time to replace a roof is late spring through early fall, primarily May to early June and September to October, when temperatures are moderate and storms less frequent. Avoid winter freezing, heavy spring thunderstorms, and peak summer heat. Watch for strong prairie winds and scheduling around harvest traffic.

Insurance & Storms

How common are storm-related roof claims in Decatur, Illinois? Storm roof claims in Decatur, Illinois are moderately common, peaking April through July during hail and strong wind storms. Macon County sees frequent hail events, and tree lined neighborhoods near the Sangamon River increase falling branch damage to older asphalt roofs. Tornado strikes are rarer but cause major claims, so document and report damage promptly.
What natural disasters in Decatur, Illinois cause the most roof replacements? In Decatur, Illinois, near Lake Decatur, severe hail and tornadoes from late spring and summer storms cause most roof replacements. Straight-line winds during derecho-style events also strip shingles. Ice and heavy snow cause occasional failures, while inland tropical remnants worsen leaks.
