Full-Service Roofing | Decatur, IL
From quick fixes to major projects, Decatur Roofing & Maintenance has been the roofing contractor Decatur homeowners call for 22 years. Here's a rundown of what we offer.
Roof Replacement
Owens Corning Duration with SureNail technology or CertainTeed Landmark with NailTrak for reliable fastening in high-wind zones. Both meet ASTM D3462 and carry Class A fire ratings per UL 790. In Illinois, we recommend the high-wind versions rated to ASTM D7158 Class H, which is 130 mph wind warranty. Full system install qualifies for Owens Corning Preferred Protection or CertainTeed SureStart Plus warranty.

Improper step flashing is the leading cause of roof leaks at wall-to-roof transitions. Step flashing needs to be woven between shingle courses with each piece extending 4" above the shingle exposure. We see Decatur homes where the last roofer used continuous L-flashing or just caulked the gap. That always fails. We tear it out and install proper step flashing with a kick-out diverter at the bottom per IRC R905.2.8.3.

Storm damage is time-sensitive. Most insurance policies in Illinois require claims within 12 months. We do a free inspection, document every damaged area with photos and measurements, and help you file the claim. If the adjuster approves it, we handle the repairs at the insurance-approved price.

New construction roofing in Decatur starts with getting the design details right before materials arrive. Roof pitch, attic ventilation needs, snow load requirements, and local code amendments all affect material selection and installation methods. We coordinate with your general contractor or architect to ensure the roof system matches the building specifications.

Metal roof repairs are usually sealant failures at transitions, loose panels from improper installation, or rust spots on older galvanized systems. Our Decatur crew repairs all metal types. Not every issue needs a full replacement. Sometimes a sealant touch-up or panel re-securing solves it.

Designer shingles like GAF Camelot II, Owens Corning Berkshire, and CertainTeed Grand Manor mimic premium materials. Slate, cedar shake, heavy wood. They cost 30-50% more than standard architectural shingles but the curb appeal is worth it for higher-end Decatur homes. Full manufacturer warranties included.

Flat roofs don't actually drain themselves. That's the challenge. Water ponds, UV breaks down the membrane, and eventually it leaks. We install and repair TPO, PVC, EPDM, modified bitumen, and built-up roofing systems designed for zero-slope conditions in Decatur.

For commercial kitchens and restaurants in Decatur, PVC membrane is the only option that resists animal fat and chemical exposure from rooftop grease exhaust. We install IB Roof Systems and Duro-Last PVC with heat-welded seams and custom accessories. Modified bitumen with SBS or APP polymer-modified asphalt for high-traffic commercial roofs. Two-ply systems with 20-year NDL (No Dollar Limit) warranties from Johns Manville or Firestone.

Seamless aluminum in 5" K-style is the standard for Decatur residential. We use 6" K-style on larger homes, steeper pitches, or roof areas with high water volume. Downspouts are 2x3" on 5" gutters and 3x4" on 6" gutters. Matched to handle the flow.

Buying or selling a home in Decatur? A roof inspection from a licensed contractor beats whatever the home inspector saw from the driveway. We check every component, give you a remaining-life estimate, and flag anything the buyer or seller should know about.
Get a Free Quote →Emergency Roof Repair
Our trucks carry 20x30 reinforced tarps, 2x4 lumber, plywood sheets, pipe boots, ridge cap shingles, flashing stock, roofing cement, and neoprene screws. We show up ready to secure your roof, not ready to schedule a follow-up appointment.
Get a Free Quote →Skylight Installation
We install three types of skylights: fixed (sealed, just for light), vented (opens for airflow. Great for bathrooms and kitchens), and tubular (flexible tube through the attic. For tight spaces where a standard skylight won't fit). Each serves a different purpose.
