Flat Roofing in Raleigh, NC
Yes — we do flat roofs. Simple Construction Roofing installs, replaces, and repairs flat roofing systems across Raleigh and the greater Triangle. From TPO and EPDM membranes on commercial buildings and apartment complexes to the low-slope sections on homes — porches, additions, and garages — our crew handles the details that make or break a flat roof: heat-welded seams, watertight flashing around every HVAC unit and vent, and drainage that actually drains.
Flat roofs fail differently than pitched roofs. Ponding water, separating seams, and flashing breakdowns around rooftop equipment are the usual suspects — and they’re exactly what we look for on every free flat roof inspection. Pictured below: a recent full TPO flat roof replacement we completed at The Ferguson Properties on Hillsborough Street in Raleigh.
Flat Roof Systems We Install
TPO (thermoplastic polyolefin). Our most common flat roof install. The bright white membrane reflects North Carolina’s summer sun, cutting cooling costs on the building below. Seams are heat-welded into a single watertight sheet, and a properly installed TPO roof lasts 20–30 years.
EPDM (rubber roofing). The proven black rubber membrane — a workhorse on older commercial buildings and a smart, cost-effective choice for many low-slope applications. Expect 25+ years with basic maintenance.
Flat roof repair. Not every flat roof needs replacing. We repair ponding-water damage, re-weld failing seams, rebuild flashing around HVAC curbs, vents, and pipe boots, and clear or correct roof drains. If a repair will honestly buy you years, we’ll tell you. If the roof is done, we’ll tell you that too.
Why Raleigh Buildings Need a Flat Roof Specialist
Flat roofs in the Triangle take a beating: standing water after summer downpours, 90°+ heat baking the membrane, and winter freeze-thaw working at every seam. The details matter more here than on any pitched roof — one bad flashing job around a rooftop unit becomes a leak inside the building. Our crew photographs and documents every penetration, curb, and drain before we start, and we don’t leave until water flows where it should.
We work on commercial buildings, multi-family properties, and residential low-slope roofs throughout Raleigh, Wake Forest, Cary, Durham, and the surrounding communities we serve.

Flat Roofing FAQs
How long does a flat roof last?
A professionally installed TPO roof lasts 20–30 years, and EPDM often goes 25 years or more. Lifespan depends on installation quality, drainage, and maintenance — the three things we focus on.
What is the best flat roofing material for North Carolina?
For most Triangle buildings, TPO. The white reflective surface handles our hot summers, resists UV damage, and lowers cooling costs. EPDM is a strong choice for budget-conscious projects and older commercial roofs.
How much does a flat roof replacement cost in Raleigh?
It depends on the roof’s size, the number of penetrations (HVAC units, vents, drains), and whether old material needs to come off. We give free, no-pressure inspections with a straight written quote — call (919) 576-9420.
Can you repair my flat roof, or does it need to be replaced?
Often we can repair it. Failed seams, damaged flashing, and isolated ponding damage are all fixable. If the membrane is brittle across the whole roof or the insulation underneath is saturated, replacement is the honest answer. Our free inspection tells you which one you’re dealing with.
Why is water ponding on my flat roof?
Flat roofs aren’t perfectly flat — they’re built with a slight slope toward drains. Ponding usually means clogged drains, settled insulation, or a slope problem. Water that stands more than 48 hours after rain accelerates membrane breakdown and voids many manufacturer warranties. We can diagnose the cause and fix it.
