For the vast majority of attic ventilation projects in Michigan — adding ridge vents, installing soffit vents, or upgrading to a balanced ridge-and-soffit system — no building permit is required, since the work doesn’t alter the home’s structure, electrical, or HVAC systems.

The exceptions are powered attic fans (which require an electrical permit because they tie into your home’s wiring) and any retrofit that involves cutting new soffit framing or modifying load-bearing rafters. In those cases, EverNew handles the entire permitting process for you — pulling the permit with your municipality, scheduling the inspection, and providing the signed-off paperwork on completion. You never have to call the city or fill out a form yourself.

The only way to determine exactly what your home needs is through a full roof and attic inspection. After that, we provide a clear, itemized quote so you know exactly what’s required.

Most homes benefit from a properly balanced ridge and soffit ventilation system, especially when airflow has been restricted over time. In some cases, improving ventilation is straightforward when existing components are working correctly. Other homes require more involved upgrades, particularly when soffits are blocked, damaged, or the roof has multiple sections that disrupt airflow.

Ice dams form when warm attic air heats the roof deck, melting snow that refreezes at the cold eave. A balanced system keeps the deck the same temperature as the outside air, so snow melts evenly off the roof instead of damming up at the gutter line.

NFVA stands for Net Free Vent Area — the actual open square inches of airflow a vent provides (a perforated soffit panel might be 10″×16″ in size but only deliver 6 sq in of NFVA). Code requires a 1:300 NFVA-to-attic ratio, split 50/50 between soffit intake and ridge exhaust. Atlas, GAF, and Owens Corning warranties all depend on it.

Yes. Zero-down financing with low monthly payments is available with approved credit. Many homeowners pair ventilation with a roof replacement or shingle upgrade — the combined project usually unlocks better financing terms.

Poor attic ventilation often shows up as premature shingle deterioration, ice dams along your roofline in winter, excessive heat buildup in summer, or moisture and mold growth in your attic space. If you’re noticing any of these warning signs, an EverNew ventilation assessment can identify the problem and map out the right solution for your home.

Yes. Most shingle manufacturers require proper attic ventilation as a condition of warranty coverage. If your intake and exhaust airflow is out of balance, heat and moisture buildup can cause shingles to fail prematurely and give the manufacturer grounds to deny a warranty claim. Getting your ventilation assessed before or after a roof replacement protects your investment from the inside out.

Absolutely. A properly ventilated attic reduces heat buildup in summer, which takes significant strain off your cooling system and lowers monthly energy costs. In winter, balanced airflow prevents warm air from escaping through your roof deck, helping your home maintain temperature more efficiently year round.
