True storm resistance is engineered to meet the local 115 mph wind speed design requirement and moderate hail risk. This starts with code-exceeding deck attachment, followed by a full synthetic underlayment and sealed eaves with ice and water shield. For the shingles, specifying an ASTM D7158 Class H (wind) and UL 2218 Class 4 (impact) rated product is a financial necessity. These shingles are tested to withstand 2-inch hail strikes and 150 mph winds, which translates directly to surviving our peak June-August storm season without damage, thereby avoiding costly deductibles and claims.

For an active leak, the immediate action is to call a contractor for emergency tarping to prevent interior damage. From our dispatch near Bryn Mawr College, we route via I-476 to reach most homes in the township within 30 to 45 minutes. The priority is to securely fasten a reinforced tarp over the compromised section, which requires specific techniques to avoid damaging the historic wood plank decking further. This tarp is a temporary mitigation; a full diagnostic inspection must follow once the weather clears to assess the underlying damage to the deck and underlayment.

Proper ventilation on an 8/12 pitch roof is a balance of intake and exhaust to manage heat and moisture. The 2018 IRC, as amended by Pennsylvania, requires a net free vent area typically equaling 1/150 of the attic floor space. Inadequate intake at the eaves on a steep gable roof creates negative pressure, which can draw conditioned, moist air from the living space into the cold attic in winter. This leads to condensation on the underside of the wood decking, promoting mold and wood rot that compromises the structure from the inside out, independent of the shingle condition.

A traditional visual inspection from the eaves or a brief walk-over cannot detect sub-surface moisture or failing fasteners. Standard diagnostic tools like infrared thermography identify thermal anomalies that indicate wet insulation or trapped moisture within the wood plank decking system. Drone photogrammetry provides a millimeter-accurate 3D model of the roof surface, revealing subtle sagging, blistering, or granule loss patterns invisible to the naked eye. This data is critical for planning a precise repair or replacement, especially on a steep 8/12 pitch roof where access is hazardous.

The decision hinges on roof age, budget, and energy goals. With PECO's 1:1 net metering and the 30% federal investment tax credit still active in 2026, both options are financially viable. For a historic district home needing a full replacement, a new architectural asphalt roof with proper flashings and attachments provides a 25+ year base for future rack-mounted panels, which generally offer higher efficiency and easier maintenance. Integrated solar shingles offer a lower-profile aesthetic but come at a significant cost premium and may complicate future roof repairs. The key is ensuring the underlying deck and underlayment are prepared for either system during the reroof.

All work in Lower Merion Township requires a permit from the Building and Planning Department and must be performed by a contractor registered with the Pennsylvania Attorney General's Home Improvement Contractor program. The 2021 Pennsylvania amendments to the 2018 IRC now mandate specific, enhanced water protection details. This includes a minimum 24-inch-wide ice and water shield membrane at the eaves and in all valleys, not just 36 inches from the interior wall line. Flashing at walls and chimneys must be integrated with the underlayment in a specific sequence. These code-prescribed methods are non-negotiable for passing inspection and ensuring long-term performance.

Yes, in the current Pennsylvania market with a 14% average premium trend, insurers are actively incentivizing storm-resilient upgrades. Installing a roof that meets the IBHS FORTIFIED Home™ standard, while not yet mandated for state credits, directly addresses the insurer's risk model. By using enhanced techniques like sealed roof decking and high-wind rated attachments, you significantly reduce the probability of a claim for wind or water damage. Many carriers now offer measurable premium reductions for these validated, damage-resistant systems, providing a direct financial return on the investment.

Your roof is approximately 75 years old, which far exceeds the service life of any original material. On a historic home in the Bryn Mawr Historic District, the original 1x6 tongue and groove pine plank decking is likely sound, but the repeated thermal expansion and contraction over decades has fatigued the fasteners and materials above it. The architectural asphalt shingles, if original, have undergone thousands of UV and moisture cycles, leading to granular loss, embrittlement, and loss of the waterproofing asphalt layer. This degradation compromises the entire assembly's ability to shed water, especially at critical details like hips and valleys.
