Delaware Roof Pros provides professional flat & low-slope roofing in Delaware, OH for residential and commercial properties across Delaware County and the Olentangy corridor. Most low-slope roofing in this city is small. A covered porch, a bay projection, a shed dormer, a sunroom bolted onto the back of a 2004 colonial. Two or three hundred square feet at a pitch too shallow for a shingle and too fussy for whoever built it.
The most common failure we find is a shingle laid at two or three in twelve because it matched the main roof visually and nobody checked the minimum pitch. Below that figure a shingle is decoration with fasteners in it, and sooner or later every one of them lets water through the headlaps in a driving rain. The homeowner is then told the roof is old, which is rarely the real problem.
On a small porch roof the right answer is usually self-adhered modified bitumen rather than a TPO patch. It handles the transition up under the main roof's courses cleanly, it takes foot traffic, and it does not need a welder on a two hundred square foot job where the seam count is low and the detail count is high. TPO earns its place at scale and on genuinely open fields, not on a bay with four inside corners.
Where the low-slope section drains onto or under a steep slope, the transition detail is the whole job. Membrane run up the main roof deck and under at least two courses, mechanically fastened along the top edge, with the steep-slope underlayment lapped over it rather than butted to it. Get that wrong and the roof leaks at the one place nobody thinks to look at.
Ponding gets treated here as a design fault rather than as a maintenance item. Standing water on a small roof means the deck sagged or was never sloped in the first place, and adding membrane over a low spot simply gives the water something newer to sit on. Tapered insulation or a sistered rafter costs a good deal more and has the singular advantage of actually fixing the thing.
We do not recover a low-slope roof that already carries two layers, and we will not quote a coating as a substitute for a tear-off when the insulation underneath is wet. There is a moisture survey for that question, and it is cheap next to the cost of being wrong about it.
Our licensed and insured team brings the right materials and equipment to every job — ASTM D1970 ice barrier membrane, step flashing woven at sidewalls, counterflashing folded into a ground-in reglet, synthetic underlayment printed with fastener grids, ASTM D3161 Class F seal strips, H-clipped 7/16-inch OSB decking — and backs the work with a written workmanship warranty. We serve Delaware and nearby communities including Powell, Sunbury, Galena, Ashley.

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 D1970 ice barrier membrane, step flashing woven at sidewalls, counterflashing folded into a ground-in reglet, synthetic underlayment printed with fastener grids, 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 Delaware 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 Delaware County and the Olentangy corridor means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
