Flat and commercial roofing covers low-slope systems (TPO, EPDM rubber, modified bitumen, built-up roofing) on the kinds of buildings a pitched-roof crew usually doesn't touch: strip malls, warehouses, apartment buildings, schools, and additions with a low-slope section. It's a different trade from residential shingle work. The membranes, seaming methods, drainage requirements, and code rules (insulation R-values, fire ratings, wind uplift) are all specific to flat systems, and installing them wrong shows up fast as ponding water and leaks around drains, seams, and parapet walls.
Middletown has 5 businesses listed in this category. That's a small enough pool that picking the wrong one has real consequences: a bad flat roof can mean water intrusion into ceiling tiles, electrical systems, or inventory before anyone notices, since low-slope leaks often travel sideways before they drip.
What to look for before you hire
- Manufacturer certification for the specific membrane system (TPO, EPDM, or modified bitumen) they plan to install, since it affects whether the material warranty is valid.
- Commercial general liability and workers' comp coverage sized for the job, not just a minimum policy.
- A real drainage plan, not just "we'll re-cover what's there." Ponding water is the most common cause of early failure on flat roofs.
- References from similar buildings, ideally other commercial or multi-family properties, not just houses.
- A written scope covering tear-off vs. recover, insulation, flashing details, and warranty terms (material warranty vs. workmanship warranty are two different things).
Our scoring weighs licensing, insurance, verified experience with commercial/low-slope systems, and how contractors respond to real customer feedback, so you're not relying on a single star rating.
