A professional roof inspection is one of the most valuable things a San Francisco homeowner can do — yet most people have never had one until there’s already a problem. Understanding what a thorough inspection actually involves helps you evaluate whether you’re getting a real assessment or a surface-level walkthrough.
How Long Does a Roof Inspection Take?
A thorough residential roof inspection in San Francisco typically takes 45 minutes to 1.5 hours, depending on roof size, complexity, and accessibility. Be cautious of any “inspection” that takes less than 20 minutes — there’s no way to properly assess a roof in that time.
What Gets Inspected on the Exterior
- Roofing material condition: Shingle granule loss, cracking, curling, blistering, or missing sections. For flat roofs: membrane condition, blistering, ponding water evidence, and seam integrity.
- Flashing: Every point where the roof meets a vertical surface — chimney, skylights, vent pipes, walls, valleys — checked for sealant condition, corrosion, and proper overlap.
- Gutters and drainage: Gutter alignment, attachment, granule accumulation, and downspout condition and routing.
- Fascia and soffit: Wood rot, paint peeling, animal intrusion points, and ventilation blockage.
- Ridge and hip condition: Ridge cap integrity is critical — it’s the highest point on the roof and takes the most weather exposure.
- Penetrations: Every pipe, vent, HVAC curb, and skylight checked for flashing and sealant condition.
What Gets Inspected on the Interior
- Roof deck condition: Soft spots, staining, mold, or daylight visible through the deck.
- Rafter and structural member condition: Signs of moisture damage, past repairs, or structural movement.
- Insulation: Depth, condition, and whether soffit vents are being blocked.
- Ventilation: Intake and exhaust vent presence, sizing, and whether air is actually moving.
Thermal Imaging: Seeing What the Eye Misses
Eco Smart Roofer uses infrared thermal imaging cameras during inspections to detect moisture that has infiltrated beneath the roof surface but isn’t yet visible. This lets us identify areas of water infiltration before they cause visible damage — catching a $500 repair before it becomes a $5,000 remediation.
What a Good Inspection Report Looks Like
After the inspection, you should receive a written report with photos documenting every finding, clearly distinguishing between immediate concerns, near-term items, and long-term planning items. A good report gives you the information to make decisions — not just a list of things wrong.
The best time for a San Francisco roof inspection is September–October, before the rainy season begins. Schedule your inspection today — we provide thorough, honest assessments with no-pressure recommendations.
