Emergency Roof Repair

A tarp run over the damaged area and fastened with wood battens, not loose rocks.
  1. Protect the inside firstMove valuables and electronics, put buckets under drips, and switch off power to any wet ceiling fixtures. If a ceiling is bulging with water, keep people out from under it and let it drain into a bucket through a small puncture at the lowest point of the bubble.
  2. Stay off the roofWet tile and shingles are slippery, and water-damaged decking can give way.
  3. Take photosPhotograph the ceiling, walls and any damage you can see from the ground, with timestamps. Your insurer will want them.
  4. Get a tarp on itSend the form and a roofer will reach out ASAP. The roofer tarps the damage first, then quotes the permanent repair for dry weather.

Emergency tarping typically costs about $250 to $900 depending on roof size and access, and the cost of a temporary tarp is often part of an insurance claim for sudden damage. Send us a message and one of our contractors will reach out to you ASAP.

What a Proper Roof Repair Involves

Once the roofing comes off, failed underlayment shows why a leak kept coming back.
  1. InspectThe roofer checks the roof surface, flashing, penetrations and drainage, and look at the attic or ceiling underneath where it's accessible. Water often travels along rafters or the deck before it shows up, so the stain and the entry point can be several feet apart.
  2. Show the evidenceYou should get photos of the damage and the entry point, not just a verbal diagnosis.
  3. Write up a scopeThe written scope lists what will be repaired, the materials, whether a permit is needed, and the price, so you can compare quotes like for like.
  4. RepairThe damaged materials are removed and replaced, not covered over.
  5. VerifyWhere it's safe to do so, a proper repair ends with a water test, followed by before-and-after photos.

Repair or Replace? Signs It's Time

A repair makes sense when the damage is limited and the rest of the roof is sound. It's usually time to look at replacement when:

  • Leaks keep coming back in different places.
  • Underlayment has failed across large areas of a tile roof, not just one section.
  • Shingles are brittle, curling or bald over most of the roof.
  • The deck is soft or rotted in several places.
  • Repairs over the past year have covered a large share of the roof.

If replacement is the better call, see Roofing Los Angeles for re-roofing options.

The 25% Rule

That last point matters because permits and code upgrades are tied to how much of the roof you redo. There's no single rule by that name. In the City of Los Angeles, reroofing more than 100 sq ft needs a permit, and small in-kind repairs usually don't. The California Building Code has reroof area provisions, and LA County allows in-kind sheathing replacement up to 25% of the roof without a permit for single-family homes, duplexes and townhouses. LADBS doesn't publish a 25% trigger, so ask Los Angeles Department of Building and Safety (LADBS) or your city's building department before approving a large repair, and don't rely on the folklore. See our roofing permits guide.

How Much Does Roof Repair Cost in Los Angeles?

Roof repair prices in Los Angeles depend on:

  • Roof type. Tile repairs involve lifting and relaying tiles, which takes more labor than shingle repairs.
  • Size of the damaged area. A few slipped tiles vs a full section of failed underlayment.
  • Access and pitch. Steep or two-story roofs need more safety setup.
  • Hidden damage. Wet or rotted decking found once the surface is opened up.
  • Flashing work. Chimney and skylight flashing takes more time than open-field repairs.
  • Urgency. Emergency tarping and after-hours call-outs.
  • Permit. Needed for some larger repairs.
RepairTypical cost in LA
Simple leak repair~$350–$1,500
Typical repair~$550–$2,100
Larger repairs (sections, decking)up to ~$8,000
Emergency tarp~$250–$900

Ranges reported by published 2025–2026 cost guides.

What's the cheapest way to repair a roof?

Fix the actual entry point properly the first time. Cheap sealant patches over failed flashing or underlayment tend to fail within a season, and the water damage underneath keeps growing. The lowest-cost repair over time is the one that doesn't need repeating.

Will insurance pay for the repair?

Insurance generally covers sudden damage, such as wind lifting tiles or a fallen branch, not gradual wear. Photograph the damage before anything is moved and check your policy's roof provisions. If you're unsure what's covered, ask your insurer or the California Department of Insurance.

Commercial Roof Repair

Commercial and multifamily roofs are mostly low-slope membranes, coatings or built-up systems, and repairing them starts with finding out whether water has soaked into the insulation beneath the surface. If it has, a surface patch won't hold. For warehouses, retail, office and apartment buildings, see commercial roofing in Los Angeles.

Who pays for roof repairs in a commercial lease?

It depends on the lease. Under many triple-net (NNN) leases the tenant pays, directly or through common-area charges. Under gross leases the landlord usually does. Check the lease's repair and maintenance clauses.

Roof Repair FAQs

How do I know if I need a roof repair?

Water stains on ceilings or walls, damp patches in the attic, missing or cracked tiles and shingles, granules in the gutters, and water ponding on flat sections for more than a day or two after rain.

Can you repair part of a tile roof without replacing it all?

Yes. Broken tiles and localized underlayment failure can usually be repaired section by section, reusing the sound tiles. On large repairs, check whether your city treats the work as a reroof.

Do I need a permit for a roof repair in Los Angeles?

Small in-kind repairs usually don't need one, but reroofing more than 100 sq ft in the City of Los Angeles does, and a large repair can count as a reroof. In the City of Los Angeles, permits come from LADBS; other cities in LA County have their own building departments.

When's the best time to repair a roof in LA?

Before the winter rain. An inspection in late summer or early autumn catches problems while repairs are easy to schedule and the roof is dry.

How do I check a roofer's license?

Search the company or license number on the CSLB license check. Look for an active C-39 roofing license and make sure the name matches the company quoting you.

What is the average cost of roof repair in California?

Published cost guides put a typical roof repair in Los Angeles at roughly $550 to $2,100, with simple leak repairs from about $350 and larger section or decking repairs up to around $8,000.

How much does it cost to fix a commercial roof?

It depends on the system and how much insulation is wet. Localised membrane and flashing repairs are priced per job, coating restorations typically run about $0.50 to $7 per square foot, and full replacement of a TPO roof about $4 to $9.50 per square foot (national ranges). See commercial roofing for the full breakdown.

How do you repair a commercial flat roof?

Find the entry point first (seams, flashing at curbs and parapets, or clogged drains), then test whether the insulation below is wet with an infrared scan or core cuts. Dry areas get seam and flashing repairs or a coating; wet insulation has to be cut out and replaced before the membrane is patched.

Does insurance pay for emergency roof repair?

Insurance generally covers sudden damage such as wind lifting tiles or a fallen branch, including reasonable temporary repairs like tarping, but not gradual wear. Photograph the damage before anything is moved and keep the tarping invoice.
