Existing Roof System
Describe the type and conditions of the various membranes types on the roof
The building features a steep-sloped roof system constructed with architectural asphalt shingles, designed for enhanced durability and aesthetic appeal. An ice and water shield membrane is installed at critical areas, such as eaves and valleys, to prevent water intrusion, while a standard underlayment covers the remaining roof deck.
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.
The client has reported staining on the interior ceilings and evidence of water infiltration. Therefore, a detailed inspection is crucial to pinpoint the precise sources of the leaks and determine the necessary repairs.
Attic/Crawl Space Inspection
Check vent/insul/deck/struct/plumb/wire/pests/moisture. Note damage, leaks, ventilation, & insulation. Photo any issues
During a more extensive inspection, the technician accessed the attic to investigate the source of the water infiltration. It was discovered that the ventilation openings in the underlayment had not been properly cut. This resulted in inadequate roof ventilation, leading to condensation buildup within the attic space and contributing to the reported leaks and staining
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.
Based on these findings, the technician removed the sections of underlayment that were obstructing the ventilation openings. It is believed that this corrective action will significantly improve roof ventilation and resolve the condensation issue, thereby preventing future leaks and staining.
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 existing shingles are IKO Cambridge Dual Black architectural shingles with an expected lifespan of 15 to 20 years. However, the roofing system was not installed using open valley flashing, and due to the fact that the roof was not adequately ventilated, this may significantly shorten the lifespan of the roof. Furthermore, because of the lack of open valley flashing and adequate ventilation, the roof is likely not warranty compliant.
