Your roof is the most expensive exterior system on your home, and it degrades silently. UV radiation bakes the granule coating off asphalt shingles. Thermal cycling cracks sealant at flashing transitions. Wind lifts shingle edges and loosens ridge cap. Portola Valley Roofing & Maintenance's roof inspection catches all of this before it becomes a $15,000 emergency.
Flashing failures cause most roof leaks, not shingle failures. That's why we check every flashing point: chimney flashing (the #1 leak source), step flashing at wall transitions, counter-flashing at masonry, pipe boots at plumbing vents, and vent boots at exhaust penetrations. We check the sealant condition at each and note any gaps, corrosion, or separation.
Our Roof Inspection Process
Appointment Setup
Quick scheduling by phone or online. Most Portola Valley inspections booked within 3-5 business days. Storm damage inspections prioritized for faster turnaround.
Surface Inspection
Full exterior roof walk. We check every square foot of shingles, every flashing transition, every penetration seal. Pipe boots squeezed for brittleness. Chimney flashing probed for gaps. Valley channels checked for debris buildup and wear. Photos taken of every finding.
Below-Deck Assessment
Attic inspection: we check ventilation balance (soffit vents vs. ridge vents), insulation depth and condition, and the underside of the roof deck for moisture. Dark stains, mold, or daylight through the sheathing signal active or past water intrusion.
Detailed Report
Your roof inspection report delivered within 48 hours. Prioritized findings, annotated photos, and repair recommendations. We walk you through the report by phone or in person if you prefer.
