Asphalt Shingle Roofing Systems

Findings

• 3-tab shingle field is fully at end-of-life, severe granule loss across every plane exposing the fiberglass mat, the point where UV starts eating the asphalt directly.
• Dozens of missing and lifted tabs across the main slopes, with prior handyman shingle patches slapped over the failures instead of proper repairs.
• Failed HVAC curb flashing on the low-slope tie-in, old sealant cracked out, penetrations exposed, active leak path straight into the ceiling below.
• Coated modified-bitumen flat section has multiple generations of patch coatings peeling apart, cracking, and delaminating from the substrate.
• Vent boots and pipe jacks on the shingle field are dry-rotted and no longer sealing around the penetrations.
• Every failure mode we found is age-driven, not storm-driven, this roof is past its service life and needs a full replacement, not another round of patches.
