Greenwood Premium Roofing provides professional roof ventilation in Greenwood, IN for residential and commercial properties across the Johnson County side of the Indianapolis metro. Nearly every ventilation problem we find on this stock is an intake problem being treated as an exhaust problem. Adding another vent to the top of a roof that cannot breathe at the bottom makes the situation worse, not better, and it is the most common upsell in the trade.
Here is why. A roof needs about half of its net free area down at the eave and the other half up at the ridge. Give it exhaust without matching intake and the ridge vent still has to draw air from somewhere, so it pulls it from inside the house through every ceiling bypass: the light cans, the bath fan housing, the hatch, the plumbing chases.
That is a heating bill and a moisture problem at once. Warm indoor air carrying moisture arrives on the cold underside of the sheathing, and by February you have frost on the nail shanks, then meltwater dripping on the insulation, and a homeowner convinced the roof leaks in dry weather. We see it every winter on houses whose roofs are perfectly sound. Dark, slightly furry sheathing across a whole plane is the same story told louder.
The fix is dull and it works. Open the blocked soffit runs, fit baffles so blown insulation stops burying the intake at the top plate, add continuous vented soffit where there is only a token panel, and size the whole thing against the attic floor area rather than guessing. One in three hundred is the ratio we work to. Where the soffit is too shallow, edge intake vents cut into the first course work.
Two details are specific to exposed sites like these. A ridge vent on a high, unsheltered ridge should be an externally baffled type, because an unbaffled one takes wind-driven rain and dry snow straight into the attic. And gable vents left open alongside a ridge vent short-circuit the flow, so the ridge draws from the gable and the soffit does nothing. Box vents mixed into a plane with a ridge vent do the same thing.
We are also happy to remove things. Powered attic fans on a house with poor intake drop the attic pressure and drag conditioned air out of the house through the ceiling, so you pay to run the fan and pay again to replace the air. Taking one out and correcting the intake is usually the cheaper and better job, and we will recommend it. Few roofing upgrades ever show up on a heating bill, and this one does.
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 roof ventilation
The difference between roof ventilation that lasts and roof ventilation 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 roof ventilation
Quality here is not a matter of opinion — it is written down. The roof ventilation 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.
Every roof ventilation project in Greenwood gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
