Absolutely. A 4/12 pitch roof in our climate requires a balanced ventilation system per the 2015 Michigan Residential Code. Inadequate intake and exhaust lead to heat and moisture buildup in the attic. This excess moisture condenses on the underside of the roof deck, promoting mold growth and prematurely aging the shingles from underneath. Proper ventilation maintains a dry, temperature-moderated attic, which is essential for shingle longevity, energy efficiency, and preventing ice dams in winter.

Given Corunna's 115 mph ultimate design wind speed zone and moderate hail risk, Class 4 impact-resistant shingles are a financial necessity, not just an upgrade. They are engineered to withstand the 1.0 to 1.25-inch hail common during our May-August peak storm season. This directly prevents granular loss and cracking that lead to leaks. For insurers, this dramatically lowers the probability of a weather-related claim, which can justify premium discounts and ensures your roof remains functional after a typical severe storm, protecting your investment.

A standard visual inspection from the ground or a walk-over can miss critical sub-surface issues, especially with architectural shingles that may hide problems. We supplement visuals with infrared moisture detection, which maps thermal differences to identify trapped moisture within the decking or insulation. This is vital for Corunna homes, where decades of minor leaks can rot the CDX plywood from underneath without visible surface warning. This diagnostic tech provides a complete system assessment, ensuring we address the root cause, not just the surface condition.

Roofs in Corunna City Center, built around 1971, are now 55 years old and have exceeded their design life. The original architectural asphalt shingles installed over 1/2 inch CDX plywood decking have endured decades of Michigan's freeze-thaw cycles and UV degradation. This repetitive expansion and contraction weakens the asphalt and compromises the nail seals. When the decking itself has been exposed to minor, undetected moisture over half a century, its structural integrity can degrade, leading to widespread failure that appears sudden but is the result of long-term environmental stress.

The decision hinges on long-term energy goals and roof readiness. Traditional architectural shingles are a proven, cost-effective solution. Solar shingles integrate energy generation, benefiting from Michigan's net metering and the 30% federal Investment Tax Credit available in 2026. However, they require a structurally sound deck and a compatible roof plane. For a 1970s-era home, we must first ensure the CDX plywood deck and framing can support the system. A hybrid approach—a FORTIFIED traditional roof with conduit pathways—future-proofs for later solar panel addition.

Yes, a roof upgrade is one of the most effective ways to counter the 18% premium trend in Michigan. By installing a roof that meets or exceeds the IBHS FORTIFIED Home standard—which Michigan insurers recognize—you directly mitigate risk. Carriers often provide substantial credits for a FORTIFIED-rated roof because its enhanced wind and hail resistance statistically reduces claim frequency and severity. This investment shifts your home into a lower-risk category, leading to long-term premium reduction and improved insurability.

An active leak requires immediate interior water diversion and exterior tarping to prevent structural damage. Our emergency dispatch from the Corunna area typically routes via McCurdy Park to access M-71, aiming for a 45-60 minute on-site arrival. The priority is to secure a water-resistant barrier over the compromised section, stabilize the attic environment, and conduct a preliminary assessment to plan for permanent repairs once the weather clears. This rapid response is critical for protecting your home's interior and the plywood decking from further water intrusion.

All work must comply with the 2015 Michigan Residential Code and be permitted through the Shiawassee County Building Department. The contractor must be licensed by the Michigan Department of Licensing and Regulatory Affairs (LARA). Current code mandates specific material applications, such as ice and water shield in valleys and at eaves, and proper step flashing integration with siding. In 2026, these details are non-negotiable for passing inspection and ensuring the roof meets the design wind speeds for our region. Using an unlicensed contractor voids these protections and can invalidate your homeowner's insurance coverage.
