London is in a 115 mph Ultimate Design Wind Speed zone (ASCE 7-22), requiring robust decking attachment and high-wind rated shingles. For the May-August hail season, specifying an optional Class 4 impact-resistant shingle is a financial necessity. These shingles are engineered to withstand moderate (1.25-inch) hail impacts without cracking, preventing the micro-perforations that lead to leaks. This combination directly addresses the two primary forces of our peak storm season and is a cornerstone of the FORTIFIED standard.

All work requires a permit from the Monroe County Building Department and must be performed by a contractor licensed by Michigan LARA. The 2015 Michigan Residential Code mandates specific material upgrades. This includes a continuous ice and water shield membrane along the eaves and in valleys, extending at least 24 inches inside the interior wall line. Flashing at walls, chimneys, and vents must be integrated with the underlayment. These are not optional 'best practices' but enforceable minimums for occupant safety and durability.

Absolutely. A 4/12 pitch roof, common in London, requires a balanced intake and exhaust system per the 2015 Michigan Residential Code. Improper venting leads to heat and moisture buildup in the attic. In summer, this superheats the living space below; in winter, it promotes condensation and mold growth on the roof decking. Correct ventilation extends shingle life by reducing thermal cycling and is a non-negotiable component of any reroofing project for both performance and code compliance.

First, contain interior damage with buckets and document the exterior with photos for your insurer. A contractor can dispatch a crew from US-23, reaching London Center within 45-60 minutes for emergency tarping. This temporary seal, properly secured over damaged sheathing, prevents catastrophic water intrusion into the attic and living spaces. Immediate action preserves the structural integrity of the plywood or OSB decking and is a critical first step before permanent repairs can be scheduled.

A 1984 build means the original architectural asphalt shingles are now 42 years old, well beyond their engineered lifespan. On the 1/2 inch OSB or plywood decking common in London, decades of Michigan's freeze-thaw cycles and UV exposure cause the shingle adhesive to crystallize and granules to shed. This aging process accelerates moisture infiltration into the decking itself, compromising the roof's primary weather barrier. Proactive replacement now prevents the higher costs of decking repair or interior damage from a sudden failure.

This is a viable financial decision now. With DTE Energy net metering and the 30% Federal Investment Tax Credit still active, solar shingles can offset a significant portion of their premium cost over time. However, they require a structurally sound deck and a south-facing plane with minimal shading. For a London home with a simple roof layout and high energy costs, integrating solar generation into the roof assembly is a forward-looking option. For complex roofs or tighter budgets, high-quality architectural shingles with a 'solar-ready' zone for future panels remain a prudent choice.

A traditional walk-over often misses sub-surface moisture trapped beneath aging architectural shingles and within the OSB decking. In 2026, standard practice combines physical inspection with emerging drone technology. Drones provide a high-resolution, magnified view of the roof plane, identifying subtle granule loss, lifted adhesive tabs, and potential moisture shadows invisible from the ground. This diagnostic tech offers a comprehensive assessment without risking further damage to the weathered shingles.

Michigan insurers are adjusting rates due to increased severe weather claims, leading to an average 18% premium trend increase in London. Upgrading to an IBHS FORTIFIED Home standard roof directly counters this by demonstrably reducing the risk of storm damage. Insurers often provide significant credits for this third-party certified system, as it lowers their expected loss ratio. The investment in a FORTIFIED roof can yield a net-positive financial return through annual premium savings over its lifespan.
