Most roof work gets booked when it rains. Ventilation is the opposite — it’s the dry-weather job that helps keep winter damage from getting started. Heat and moisture trapped in a hot attic are a leading cause of Michigan ice dams, and ventilation is one part of controlling them — alongside sealing the air leaks that let warm house air up, and insulation that does its job. Bathroom air dumped into an attic causes stains and frost that look exactly like leaks. We fix the roof side of all of it, across Wayne, Oakland, and Macomb counties.
We fix roofs. We don’t sell roofs. Ventilation and exhaust hookups are roof work — so they’re ours.

What’s included
Balanced intake and exhaust: ridge vent $26 / lin ft, soffit vents $95 / vent, baffles $38 / bay, roof vent or turbine repair $425 – $650 — the published price book, as written.
A solar-powered vent fan mounted on the roof that pulls hot air out of the attic. It runs on sunlight — no wiring into the house, no electrician needed. Price agreed in writing before work begins.
Bathroom and dryer vents terminated through the roof with a proper roof cap — reroute $550 – $850 as published. Kitchen exhaust vents through the roof too, priced in writing at your estimate.
Ventilation works as a pair. Cool air comes in low, through the soffits, and hot air leaves high, through the ridge or roof vents — baffles keep insulation from choking that intake at the eaves. When any leg of that system is missing, attic heat melts roof snow unevenly, the meltwater refreezes at the cold eave, and you get an ice dam. That’s why our ice dam guide treats ventilation as part of the root-cause fix — together with sealing the air leaks from the house below and insulation that isn’t blocking the eaves — not an extra.
From the price book: ridge vent repair $26 / lin ft · soffit vent installation $95 / vent · baffle installation $38 / bay · roof vent or turbine repair $425 – $650. Book it in dry weather this fall and winter has one less way in.
A solar attic vent is a fan we mount on the roof that moves hot attic air out whenever the sun is up — which is exactly when the attic is hottest. Because it runs on sunlight, there’s no wiring into the house and no electrician needed: we set it, flash it into the roof, and it runs itself. It pairs with the intake side — soffit vents and baffles — so the air it pulls out is swapped out with cooler air from below. For solar attic vent installation, the price is agreed in writing before work begins.
Plenty of bathroom fans and dryer vents around Metro Detroit were never hooked up properly — the duct just ends in the attic, dumping warm, wet air onto cold roof decking. The result looks like a roof leak: ceiling stains, a musty mold smell, even frost inside the attic in winter. It isn’t the roof leaking; it’s the house breathing into the wrong room. We reroute the duct and terminate it through the roof with a flashed roof cap — bathroom / dryer vent reroute $550 – $850, as published. Kitchen exhaust vents go through the roof the same way; that hookup is its own line, priced in writing at your estimate before work begins.
Our boundary, in plain words: we do the roof side — the vent cap, flashing, and the duct connection through the roof. We don’t do electrical work; if the fan itself needs wiring, that’s an electrician — the roof part is ours.

Questions
Usually a few causes working together: warm, moist air leaking up from the house, insulation that’s thin or blocking the eaves, and attic air that can’t move — not enough intake at the soffits or not enough exhaust at the ridge. Warm attic air melts snow unevenly (that’s the ice dam), and summer heat trapped in the attic cooks shingles from underneath. Ventilation is the part we fix from the roof side — the intake and the exhaust — and we’ll tell you plainly if air leaks or insulation look like part of your problem too.
It’s published in our price book: ridge vent repair $26 / lin ft, soffit vent installation $95 / vent, baffle installation $38 / bay, and roof vent or turbine repair $425 – $650. Solar attic vent installation is priced in writing after review, before work begins.
No. A solar attic vent runs on its own solar panel — no wiring into your house and no electrician. We install the roof side: the vent itself, properly flashed into your roof. Our boundary is simple — we do roof work, not electrical work. If something inside the house needs wiring, that’s an electrician, and we’ll tell you plainly.
Yes, it’s a problem: every shower pumps warm, moist air into your attic, where it feeds musty smells, attic frost, and ceiling stains that look exactly like roof leaks. We reroute bathroom and dryer vents and terminate them properly through the roof — published at $550 – $850. Kitchen exhaust vents through the roof are the same idea; that one is priced in writing after review, before work begins.
No — a photo is a clue, not a diagnosis. We can’t determine the cause or guarantee a fix from a photo alone. Tell us what’s happening with your roof. We’ll review the information and contact you about the next step.
Short answer: Maybe — what matters is balance, not just more vents. A roof vents as a system: cool air comes in low through the soffits and hot air leaves high through the ridge. If intake and exhaust aren't balanced, adding vents in one place alone doesn't fix it.

Short answer: If your roof has ridge vents up top, it almost always needs soffit vents down low too — that's the intake half of the system.
MDRR installs soffit vents ($95 per vent, per our price list). Tell us what's happening with your roof. We'll review the information and contact you about the next step. (586) 698-7094.
Short answer: Both are fans that actively pull hot air out of the attic. A power vent runs on house electricity; a solar vent runs on its own small solar panel.

Short answer: Yes — kitchen range air should vent outside through the roof, never into the attic.

Short answer: Usually that's a good sign — it means heat is staying inside your house instead of leaking into the attic.

Short answer: Yes, dark shingles absorb more sun and run hotter — but color alone isn't the whole story. Ventilation matters more.

Short answer: Musty usually means moisture is getting in and staying there — poor ventilation, a small leak, or damp insulation.

Short answer: Warm air escaping into the attic melts roof snow, and the meltwater refreezes at the colder eaves — that ridge of ice is the dam.

Short answer: You usually notice the effects first — a very hot attic, moisture, or shingles aging fast — because the vent itself is on top of the roof.

Short answer: If your attic floor insulation is thin, patchy, or old, probably — but insulation alone doesn't fix ventilation problems.

Short answer: Both point at the same thing — warm house air leaking up, and an attic that can't breathe.
