What's included
What Our Roof Leak Detection Includes
Every Roof Leak Detection in Covina appointment includes a full attic and roof inspection, moisture mapping, and a written report. We also include a same-day repair quote. Here is exactly what you get when you book with us.
Full Attic Inspection
We inspect the attic with a boroscope inspection camera and moisture meter to find water trails, stained sheathing, and wet insulation. This step often reveals the leak source before we even get on the roof.
Roof Surface Check
We walk the roof and check flashing, pipe boots, skylights, vents, and shingles. We look for damaged shingles, cracked sealant, and rusted flashing. Every finding is photographed and documented.
Moisture Mapping
Using a Tramex moisture meter and infrared thermal imaging camera, we map the moisture levels across your roof deck. This tells us how far water has spread and whether sheathing or insulation needs replacement.
Water Test Confirmation
We run a controlled water hose test on the suspect area to confirm the entry point. You see the test and the results. This eliminates guesswork and ensures we repair the right spot the first time.
Written Report and Quote
You get a written report with photos, moisture readings, and a repair quote. The quote includes materials, labor, and timeline. No hidden fees. If you approve, we can often start the repair the same day.
Service overview
Roof Leak Detection in Covina: What It Is
Roof Leak Detection in Covina is the process of finding the exact source of a roof leak using tools like moisture meters, infrared thermal imaging cameras, and electronic leak detection equipment. Water travels along rafters and underlayment, so the stain on your ceiling is rarely right below the hole. We trace the path from the attic down, inspect flashing, pipe boots, and shingles, then confirm the entry point with a water hose test before we quote any repair.
Covina homes face intense sun, Santa Ana winds, and winter rain that push water through worn flashing and cracked sealant. If you have a ceiling water stain or a musty attic smell, waiting makes it worse. Our roof leak detection services Covina CA include a full attic inspection and a written report. We serve Downtown Covina, Covina Hills, and the 91722, 91723, and 91724 ZIP codes. Call us before the next storm.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
Our Roof Leak Detection Process
The process flexes to the condition, but these checkpoints keep decisions clear.
Phone Triage
When you call, we ask where you see water, how long it has been happening, and whether the ceiling is bulging. We book a same-day or next-morning appointment and tell you what to do in the meantime, like moving furniture and placing a bucket. The call takes 5 to 10 minutes.
On-Site Inspection
Our technician arrives with a moisture meter, infrared thermal imaging camera, and boroscope inspection camera. We inspect the attic first, then the roof surface, checking flashing, pipe boots, skylights, and shingles. This step takes 45 to 90 minutes depending on roof size and access.
Leak Confirmation
We do not guess. Once we have a suspect area, we run a water hose test to confirm the entry point. If needed, we use a Tramex moisture meter to map moisture in the sheathing and insulation. You see the readings and photos before we recommend any repair.
Repair or Patch
Most leaks come from failed flashing, cracked pipe boots, or damaged shingles. We carry GAF and Owens Corning materials on the truck, so we can repair many leaks the same day. If the damage is bigger, we give you a written scope and schedule the work.
Final Test and Cleanup
After the repair, we run another water test to confirm the leak is stopped. We clean up all debris, haul away old materials, and give you a written warranty on the workmanship. You get before-and-after photos and a maintenance tip sheet for your roof type.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Tramex Moisture Meter
Measures moisture content in roofing materials, sheathing, and insulation without damaging surfaces. It tells us exactly how wet the roof deck is.
FLIR Infrared Thermal Imaging Camera
Detects temperature differences caused by hidden moisture. We use it to scan ceilings and roof decks for wet areas that are not visible to the eye.
Electronic Leak Detection Equipment
For flat and low-slope roofs, this equipment sends a low-voltage current across the membrane to pinpoint breaches. It is highly accurate on commercial and residential flat roofs.
Boroscope Inspection Camera
A flexible camera that lets us see inside wall cavities, attic spaces, and under roof decks without cutting holes. We use it to confirm water paths.
Water Hose Test Equipment
We use a controlled water spray to replicate rain on a suspect area. This confirms the entry point before we make any repair.
Drones for Roof Inspection
For steep or tall roofs, we use drones to capture high-resolution images safely. This helps us document damage without putting anyone at risk.
Use cases
When to Call for Roof Leak Detection
These examples show how the service framework adapts rather than forcing every call through one repair.
Flat Roof Leak Repaired in Covina Hills
A flat roof over a garage was ponding water and leaking into the garage ceiling. The membrane had small cracks and the drain was clogged. The homeowner was using buckets to catch drips. → We cleared the drain, repaired the membrane with roofing cement and a patch, and added a new drain. The ponding stopped and the garage stayed dry through the next rainy season. Cost: $950.
Skylight Leak Stopped in 91724
Water was dripping around a skylight during every storm. The flashing was rusted and the sealant was gone. The drywall around the skylight was soft and stained. → We removed the old flashing, installed new ice and water shield, and resealed the skylight with code-correct flashing. We tested with a water hose. No leaks. Cost: $680.
Problems we solve
Roof Leak Problems We Solve in Covina
We handle every type of roof leak Covina homes throw at us. Here are the most common problems we solve and what happens if you ignore them.
Ceiling water stains and dripping
We trace the stain back to the entry point using thermal imaging and moisture meters. Then we repair the flashing, shingle, or boot that failed. Most ceiling leaks are fixed the same day for $350 to $900.
Roof flashing leaks around chimneys and walls
We remove old flashing, inspect the underlayment, and install new code-correct flashing sealed with roof cement and ice and water shield. We test with a water hose before closing up.
Clogged gutters causing leaks
We clear the gutters, check the roof edge for damage, and repair any rotted fascia. We also recommend gutter guards if you have large trees nearby. This service often costs under $300.
Pricing process
Roof Leak Detection Pricing in Covina
$250 - $1,500 depending on scope
Leak Source and Access
A simple pipe boot replacement is quick and cheap. A leak behind siding or under a flat roof membrane takes more time and materials. Access matters too. Steep roofs and tight attics slow us down.
Roof Type and Material
Asphalt shingles are the easiest to repair. Tile, metal, and flat membranes require specialized materials and more labor. We carry GAF, Owens Corning, and CertainTeed products for shingle roofs.
Extent of Water Damage
If water has rotted sheathing or insulation, we need to replace those materials. That adds cost. Catching a leak early usually keeps the repair under $600. Waiting can push it past $1,500.
Customer reviews
What Covina Homeowners Say
★★★★★
“We had a water stain on our ceiling for weeks and two other companies could not find the source. Roof Repair Experts came out with a thermal camera and found a cracked pipe boot in 20 minutes. They fixed it the same day for $380. No more stain, no more leak. Highly recommend.”
★★★★★
“After the last big storm, water was coming through our skylight. I called at 7 a.m. and they were here by 10. They tarped the roof and came back two days later to replace the flashing. Total cost was $850. Professional, on time, and they cleaned up everything.”
★★★★★
“Our flat roof had ponding and a slow leak into the garage. The team used a moisture meter to map the water and showed me photos of the problem. They repaired the membrane and added a drain. It has been dry through two rainy seasons now. Fair price and great communication.”
How does roof leak detection work in Covina CA?
We start in the attic with a moisture meter and infrared thermal imaging camera to map where water is traveling. Then we inspect the roof surface, checking flashing, pipe boots, and shingles. We confirm the entry point with a water hose test. The whole process takes 45 to 90 minutes and you get photos and a written report.
How much does roof leak repair cost in Covina California?
Most roof leak repairs in Covina run $350 to $1,200 in 2026, depending on the source. A simple pipe boot replacement is on the low end. Flashing repair or shingle replacement costs more. If the leak has rotted sheathing, expect $1,500 or more. We give you a written price before any work starts.
Can you repair a roof leak in the rain in Covina CA?
Yes, we can stop an active leak in the rain. We tarp the roof to divert water and prevent further damage. Permanent repairs usually wait until the roof is dry, because sealants and membranes need dry conditions to bond. We schedule the permanent fix within 24 to 48 hours after the storm passes.
What causes roof leaks in Covina CA homes?
The most common causes we see are failed flashing, cracked pipe boots, damaged shingles, and clogged gutters that back water under the roof edge. Flat roof ponding and skylight leaks are also common. Covina's intense sun and Santa Ana winds dry out sealant and lift shingles, which lets winter rain in.
