🩺 Patient: Historic spiritual center with multi-phase roof deterioration across gambrel, mansard, and dormer features. Referred by: Building manager after chronic leaks, visible shingle loss, and failing cedar siding exposed deeper systemic failure. 🤕 Symptoms: -Water infiltration at multiple transitions: gambrel slopes, mansard returns, and dormer cheek walls. -Rotten decking hidden beneath shingle layers, with underlayment improperly installed or missing altogether. -Aging cedar shake siding on dormers curling and shedding. -Patchwork metal flashing that was insufficient and improperly sealed. -Failing gutter system allowing water to back up against eaves and wall lines. 🧠 Diagnosis: This wasn’t just a roof issue—it was a preservation issue. The building’s architectural charm was being compromised by decades of shortcut repairs and surface-level fixes. Dormers, with their vulnerable angles and complex transitions, had become water traps. Improper flashing and the absence of a breathable but waterproof underlayment created internal rot and systemic vulnerability. This project had to do more than “stop the leaks.” It had to respect the original character of the building while bringing it into modern standards for protection and longevity. 🛠️ Treatment Plan: Phase 1 (East End): -Full tear-off down to deck on gambrel, mansard, and dormer zones (2000 sq ft) -CDX plywood installed over existing decking for structural stability, staggered and rafter-fastened -Polyglass ice & water shield applied to 100% of roof surface -Drip edge and rake trim installed for sharp water channeling -Owens Corning Duration shingles with SureNail installed to manufacturer spec -Custom aluminum flashing bent to tuck cleanly behind drip edge and cover exposed nail lines -Cedar shake siding restored on all 3 dormers after vapor barrier install -NeverLeak pipe boots, woven valleys, and Snow Country ridge vent system integrated Phases 2 + 3 (Northwest, Southwest, Southeast Wings - 4600 sq ft): -Repeat of full roof system protocol, extended to entire perimeter slope system -13 dormer cheek walls stripped and re-sided in custom cedar shake -All peaks capped with Owens Corning ProEdge hip/ridge for tight finish -Seamless system integration across multiple roof planes with hips, valleys, and historical details preserved 💡 Prognosis: This spiritual sanctuary now has a roof that honors its architectural soul — and protects it for decades to come. No band-aids. No shortcuts. Just structural clarity, water-tight transitions, and historically respectful detailing. COSM is now covered — literally and symbolically.
