Existing Roof System
Describe the type and conditions of the various membranes types on the roof
The cedar shake roof on the upper section of this single-story structure is showing significant signs of age and deterioration. The cedar shakes themselves are brittle and cracking, with numerous nails and staples protruding, indicating a high probability of future failures. Additionally, while the vent storm collars are in good condition, the metal vents exhibit rust and require fastener replacement or re-caulking, and some gooseneck vents need replacement. The skylight is also showing signs of age with a rusted metal frame and rusted fasteners, indicating a need for replacement. Therefore, complete replacement of the cedar shakes and skylight are strongly recommended, along with repairs or replacement of the vent system hardware, to prevent future water damage.
Interior Condition, Leaks, Insulation, Roof Deck Type
Collect pictures to help depict the issues presenting on the interior of the building, if accessible collect images of any below deck insulation and the roof deck type.
Interior inspection revealed water staining on the ceiling and in areas surrounding the skylights. This indicates potential leaks or condensation buildup within the attic space, likely due to inadequate ventilation. We strongly recommend incorporating additional intake vents during the roof replacement process to improve attic ventilation and mitigate future moisture-related issues.
Attic/Crawl Space Inspection
Check vent/insul/deck/struct/plumb/wire/pests/moisture. Note damage, leaks, ventilation, & insulation. Photo any issues
After discussions with the client and reviewing assessments from previous roofing technicians, it was further concluded that inadequate attic ventilation is a significant concern. Any issues found on the exterior of the building were rectified as a temporary solution to maintain waterproofing until the roof replacement occurs.
Exterior Roof Inspection
Exterior roof inspections assess the visible condition, including damaged shingles/tiles, leaks, flashing, and gutters. Flat roofs require close membrane scrutiny: blisters, cracks, seams, and ponding areas. Check for rot, mold, structural issues, ventilation, and chimney condition. Document findings with photos, noting membrane type and condition. Prioritize safety and thoroughness.
The adjoining buildings were observed to be in a similar state of deterioration, with numerous issues affecting the cedar shakes. On the building inspected, technicians rectified several immediate concerns. However, pre-existing issues, such as areas where plumbing stacks and other penetrations were improperly covered, were noted and will likely lead to future problems. The cedar shakes, including cap shingles, were found to be severely degraded, with many missing. The roof's overall age and the compromised condition of the underlayment further necessitate complete roof replacement.
Exterior Roof Materials
Meticulous documentation of the existing roofing system is essential. For color, capture well-lit photos from various angles, noting manufacturer and color names. If unknown, compare physical samples to color charts under natural light. A cut test requires careful removal of a small section, noting material layers, thickness, and degradation. Photograph the cut and surrounding area, recording markings. Additionally, document insulation type (fiberglass, foam, etc.) and thickness. Record fiberboard composition and condition (water damage, delamination). Specify the vapor barrier type (polyethylene, kraft paper) and condition (tears, punctures). During the cut test, examine underlayment and roof deck type (plywood, OSB, etc.). Ensure thorough documentation of all materials for accurate matching and assessment.
The cardiologist building roof can be divided into three sections: the east, middle, and west sections. The east section contains two skylights facing north, the middle section contains one skylight facing north, and the west section contains two skylights facing north. We are currently addressing a leak located between the skylights in the west section.
