Why San Francisco Roofs Leak

San Francisco puts roofs through a lot. Coastal fog sits on your roof for weeks. Atmospheric river storms dump water faster than drains can handle. UV from warm summers dries out membranes and caulk. Wind off the bay gets under shingles and flashing.

These are the most common causes of roof leaks we see on San Francisco homes and commercial buildings:

We locate the exact leak source using infrared moisture scanning and moisture meters. You get a clear diagnosis before any work begins. Ignoring these issues will lead to more damage and you may have to bear expense of new roof installation.

Emergency Roof Leak Repair (24/7)

Storm Damage Roof Repair

A roof leak in a commercial building costs money fast. Damaged inventory, business interruption, liability from wet floors, an active leak in a warehouse, retail space, or office building is an emergency every time.

We are trusted commercial roof leak repair contractor in San Francisco serving retail buildings, office spaces, warehouses, restaurants, apartment buildings, schools, and industrial properties.

Mold, Moisture & Interior Damage Repairs

Water that gets into a building causes damage at multiple layers, the roof membrane, the deck, the insulation, the ceiling, and sometimes the structural framing gets affected. Tom Lee Roofing documents every layer of damage in writing, with photos, so your insurance claim has what it needs.

Flat Roof Leak Repair

When a flat roof leaks, water spreads across a wide area before showing up as a ceiling stain, which means the damage is usually worse than it looks. We specialize in flat roof leak repair across every membrane type. We use infrared scanning and moisture meters to find the exact failure point, then repair it with materials matched to the existing system

Metal Roof Leak Repair Services

Metal roofs last a long time but they still develop leaks at seams, fastener holes, flashing connections, and penetrations. We fix leaks on standing seam, corrugated, and steel panel roofing systems across San Francisco.

Roof Waterproofing & Coating Repairss

For flat and low-slope commercial roofs with recurring leaks or an aging membrane that is not yet ready for full replacement, a restoration coating can extend roof life by 10 to 15 years and stop leaks for good.

FAQs

How quickly can you respond to an emergency roof leak in San Francisco?

Roofing prioritizes emergency calls and aims to respond same day or next day for active leaks in San Francisco. During major storm events, response times can extend but we keep emergency crews deployed during San Francisco's storm seasons specifically to keep wait times down.

How much does roof leak repair cost in San Francisco?

The average roof repair in San Francisco runs around $1,835, with most jobs falling between $974 and $2,697. A simple shingle patch or small flashing repair can cost as little as $350 to $800. Major storm damage repairs with deck and sheathing replacement can reach $5,000 to $10,000 or more. Tom Lee Roofing provides a written estimate before any work begins so you know exactly what to expect.

Does homeowners insurance cover roof leaks in California?

Tn California, homeowners insurance typically covers sudden and accidental roof damage, storm damage, wind, hail, and falling debris. It generally does not cover leaks caused by lack of maintenance or gradual wear.

Can you repair a flat roof on a San Francisco commercial building?

Yes. Tom Lee Roofing regularly repairs flat and low-slope roofs on commercial buildings throughout San Francisco and the Bay Area. We work with TPO, EPDM, PVC, modified bitumen, and built-up systems. We also apply restoration coatings to extend flat roof life without full replacement.

What happens if you ignore a roof leak?

A small roof leak left unrepaired can cause serious damage within weeks. Water soaks through insulation, rots the roof deck and structural sheathing, stains and destroys drywall ceilings, and creates conditions for mold growth within 24 to 48 hours. What costs a few hundred dollars to fix as a small leak can become a $5,000 to $15,000 repair if left to spread. Act as soon as you see a stain or drip.

What is the best time of year for roof repair in San Francisco?

In San Francisco, the best window for non-emergency roof repairs is late spring through early fall , roughly May through September, when dry weather is most reliable. However, leaks should be addressed immediately regardless of season.

Do I need a permit for roof repairs in San Francisco?

Minor repairs like shingle patching and small flashing fixes typically do not require a permit in San Francisco. Larger jobs especially those covering more than 25% of the roof area, structural repairs, or full re-roofing require a permit through the San Francisco Department of Building Inspection (DBI).

How do I temporarily stop a roof leak before the roofer arrives?

Place a waterproof tarp over the damaged area and secure it at the edges with boards or sandbags to prevent wind from lifting it. Inside, place buckets under active drip points and move any valuables, electronics, or furniture away from the wet area.
