Peoria Roof Pros provides professional flat & low-slope roofing in Peoria, IL for residential and commercial properties across the central Illinois River valley. Most low-slope work in Peoria, IL is not a flat commercial building. It is the back half of an older house: a rear addition, a porch deck, a shed dormer roof over a kitchen that was added in 1948 and has been patched ever since.
Those roofs share one problem and the bluff makes it worse. A low-slope rear addition on a hillside lot drains toward whatever is behind it, and behind it is the hill. There is often nowhere for the water to go, so it sits, finds the wall junction, and comes in at the ceiling line where the addition meets the original house. It sits, finds the wall junction, and shows up at the ceiling line inside.
The fix is usually not a bigger membrane, it is a slope. We build tapered insulation crickets to move water to a real edge and then take it away with a scupper and a leader rather than letting it sheet off onto the hillside. Getting the water off the roof is the cheap part. Getting it away from the foundation is where the job is won.
For the membrane itself, we use fully adhered EPDM on small residential decks because it handles movement and detailing around old brick better than anything else at that size. TPO goes on larger fields where the reflectivity pays. Two-ply SBS modified bitumen still has a place on roofs that get walked, because it takes traffic that a single-ply will not. Rear additions here also tend to be where the air conditioner sits, so somebody walks that roof.
Torch-down over a wood deck on a hundred-year-old bluff house is something we decline. There is usually knob-and-tube in a wall somewhere, dry board sheathing underneath, and no good reason to bring an open flame into that building. Self-adhered and cold-applied systems get to the same place without the risk. Cold-applied and self-adhered systems reach the same place without an open flame near dry lath.
The honest downsell here is real. A ten-year-old EPDM deck with one bad seam and no ponding needs a seam repair and a walk-over next spring, not a replacement. We will do the seam, take photographs of the rest and tell you roughly how many years you have. Nobody needs to spend four figures to fix eighteen inches of failed lap.
Our licensed and insured team brings the right materials and equipment to every job — ASTM D3161 Class F laminated shingles specified above the bluff rim and not below it, six fasteners per shingle where the standard schedule calls for four, high-wind starter strip cemented along the eaves and both rakes, hot-dipped galvanized drip edge screwed to the deck rather than hand-nailed, half-inch OSB re-decking laid over 1x6 board sheathing with skip gaps, 24-gauge standing seam panels roll-formed off site when a lot has no lay-out room — and backs the work with a written workmanship warranty. We serve Peoria and nearby communities including East Peoria, Peoria Heights, West Peoria, Bartonville.

Materials, equipment and how we do flat & low-slope roofing
The difference between flat & low-slope roofing that lasts and flat & low-slope roofing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with ASTM D3161 Class F laminated shingles specified above the bluff rim and not below it, six fasteners per shingle where the standard schedule calls for four, high-wind starter strip cemented along the eaves and both rakes, hot-dipped galvanized drip edge screwed to the deck rather than hand-nailed, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Peoria job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the central Illinois River valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Peoria Chooses Peoria Roof Pros
- ✓We look up the elevation and lot grade at your address before the appointment, because on the Peoria bluff the ground around the house predicts the cost of the roof better than the roof does.
- ✓The fastening specification changes by exposure zone. Six nails per shingle and cemented starter at both rakes on the plateau rim, and the standard schedule down on the valley floor where that load never arrives.
- ✓Staging is a named line item. Where the debris trailer sits, where material lands, and how far it is hand-carried are on the first page of the bid rather than found on tear-off morning.
- ✓We refuse coatings over steep-slope shingles outright, and we refuse tile conversions with no structural engineer's letter naming the load.
