Greenwood Premium Roofing provides professional flat & low-slope roofing in Greenwood, IN for residential and commercial properties across the Johnson County side of the Indianapolis metro. Low slope on a Greenwood house is rarely the whole roof. It is a porch, a room over the garage, a bay, or the flat-topped dormer on a 1990s two-story, and those few square feet account for a startling share of our leak calls.
The reason is simple. Below about two in twelve, water no longer runs off faster than wind and surface tension can push it back up under a lap, so a shingle stops being a waterproofing product and becomes a decoration. Shingles laid on a one-in-twelve porch will leak. It is not a workmanship question, it is what the material is. Two and a half in twelve is where we start being comfortable with shingle at all.
The right materials for these areas are self-adhered modified bitumen, a fully adhered EPDM sheet, or heat-welded TPO where the area is large enough to justify bringing a welder. All three give you a continuous membrane with no laps depending on gravity, and all three can be flashed up a wall and terminated properly instead of caulked. Fully adhered EPDM is the quietest of the three and the easiest to repair years later.
The failure point is almost never the middle of the low-slope area. It is the transition where the membrane meets the shingle field above it. That joint wants the membrane carried well up under the steep-slope underlayment, a metal transition with a hemmed drip, and counterflashing where it meets a wall. Sealant at that joint is a twelve-month repair sold as a permanent one.
Drainage on these small areas is worth arguing about. A porch roof with a scupper that discharges onto the shingles below will strip granules in a stripe you can see from the yard, and a room-over-garage roof pitched back toward the house wall will pond against the siding. We would rather re-slope with tapered insulation than replace the same membrane twice. Scuppers get a proper conductor head rather than an open hole in the wall.
On genuinely flat residential decks we will also tell you when the honest fix is framing rather than roofing. If the deck sags enough to pond an inch of standing water after every rain, no membrane on the market fixes that permanently, and money spent on the membrane before the structure is money spent twice. Sistering the joists or adding a tapered layer is the honest repair, and we quote it that way.
Our licensed and insured team brings the right materials and equipment to every job — ASTM D7158 Class H wind-rated laminate shingles, six-nail fastening set on the common bond line, full starter strip run up both rakes, not only the eaves, hemmed aluminum rake metal and eave drip edge, self-adhered ice barrier at the eave line, synthetic underlayment fixed with capped fasteners — and backs the work with a written workmanship warranty. We serve Greenwood and nearby communities including Franklin, Bargersville, New Whiteland, Whiteland.

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 D7158 Class H wind-rated laminate shingles, six-nail fastening set on the common bond line, full starter strip run up both rakes, not only the eaves, hemmed aluminum rake metal and eave drip edge, 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 Greenwood 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 Johnson County side of the Indianapolis metro means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Greenwood Chooses Greenwood Premium Roofing
- ✓We scope the windward plane and the sheltered plane as two separate questions, and price them that way, because on an exposed Greenwood lot they are not in the same condition.
- ✓We establish whether your address is inside the Greenwood city limits or in unincorporated White River or Pleasant Township before quoting, because it decides which building authority signs the work off.
- ✓We photograph creased tabs individually. A folded shingle that dropped back into place has already failed, and it is the finding most often walked past on a Johnson County roof.
- ✓We will not coat, seal or rejuvenate a steep-slope asphalt roof, and we turn that work away several times a season rather than sell something that cannot reach the failed bond line.
The standards behind flat & low-slope roofing
Quality here is not a matter of opinion — it is written down. The flat & low-slope roofing work we do in Greenwood follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
