Modified Bitumen Installation in Bloomington, IL
Flat and low-slope sections need something different from standard shingles, and that’s where modified bitumen comes in. We install this reinforced asphalt system — built with modifiers for flexibility and waterproofing — on commercial and residential structures across the 61704 area.
Local Roofing Conditions
Cold winters bring ice dams, and summer hail and wind storms are just part of the deal in central Illinois. Modified bitumen holds up well on the low-slope roofs common near Illinois State University and downtown, where standard shingles usually don’t last. Any material change goes through the City of Bloomington’s permit process, and that includes an inspection for ventilation compliance.
What Installation Involves
Ponding water, granule loss, or a low-slope section that just won’t stop leaking — that’s usually what gets someone looking into this system. We check the deck condition first, then install the membrane with proper flashing so water has nowhere to get in. Leave that kind of leak alone long enough and you’re dealing with attic moisture and deck rot.
Track Record and Credentials
We’ve completed hundreds of roofing projects since we started, and we carry full licensing and insurance along with manufacturer certifications for modified bitumen systems specifically. Workmanship warranties on this work run multiple years.
