What's included
What Roof Leak Detection in Covina in Covina includes
Every detection visit covers a full interior and exterior inspection, moisture mapping, and a written report with photos. Repair work is quoted separately so you can decide what to fix now and what can wait. Here is what you get.
Full attic moisture survey
We inspect attic decking, insulation, and rafters with a Tramex moisture meter and boroscope camera. You get a map of wet areas and a clear explanation of how far water has traveled from the entry point.
Roof-level leak inspection
We walk the roof and check flashing, shingles, pipe boots, skylights, and membrane seams. A FLIR thermal imaging camera helps spot hidden moisture under the surface. We photograph every suspect area.
Water hose test
When the source is not obvious, we run controlled water over suspect zones one at a time. This confirms the exact entry point before any repair is quoted. It is the most reliable way to prove a leak.
Written report with photos
You receive a same-day summary of findings, including moisture readings, photos, and recommended repairs. This report is useful for insurance claims and for tracking the leak over time.
Repair quote and options
If repair is needed, we provide an itemized quote with materials and labor. You choose the scope. We can often start the fix the same day for active leaks in Covina.
Service overview
What Roof Leak Detection in Covina in Covina actually involves
Roof Leak Detection in Covina in Covina is a diagnostic service that pinpoints the exact entry point of water before it spreads through your attic, insulation, and drywall. We do not guess from the ceiling stain. We climb the roof, scan the deck with an infrared thermal imaging camera, and confirm with a Tramex moisture meter and water hose test. On flat roofs we check for ponding; on shingle roofs we inspect pipe boots, ice and water shield, and chimney flashing.
Covina homes take a beating from October through March, when Santa Ana winds strip shingles and heavy rain finds every gap. By summer, UV exposure dries out roof sealant and cracks flashing. If you search for roof leak detection in Covina CA near me after a storm, we can usually get eyes on the roof the same day. We also handle affordable roof leak repair in Covina CA once the source is confirmed.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
Our roof leak detection process, step by step
The process flexes to the condition, but these checkpoints keep decisions clear.
Phone triage
You call 626-669-3791 and describe what you see: ceiling water stains, a drip in the attic, or a wet patch near a skylight. We ask three or four questions to narrow the likely source, then schedule a visit. Most calls in Covina get a same-day or next-morning window.
Attic and interior scan
We start inside with a boroscope inspection camera and a Tramex moisture meter. This tells us how far water has traveled and whether the leak is active. We photograph every reading so you can see the difference between a new leak and an old stain.
Roof-level inspection
On the roof, we check flashing, pipe boots, shingles, and roofing membrane. A FLIR infrared thermal imaging camera reveals cooler, wet areas that are invisible to the eye. We also look for clogged gutters causing leaks and flat roof ponding that can back up under seams.
Water test and confirmation
We run a controlled water hose test on suspect areas, one zone at a time. This confirms the exact entry point before we quote any repair. If the leak only shows up in wind-driven rain, we note that and test the windward flashing and ice and water shield.
Repair plan and fix
You get a written scope with photos, a price, and a timeline. Once approved, we replace damaged shingles, re-seal flashing with roof cement or roof sealant, and install new pipe boots if needed. We test the repair with water before we leave.
Tools & methods
Tools and methods we use for roof leak detection
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
FLIR infrared thermal imaging camera
Detects temperature differences caused by hidden moisture in roof decks and walls. We use it to scan large areas quickly and pinpoint wet zones that are invisible to the eye.
Tramex moisture meter
Measures actual moisture content in shingles, underlayment, and attic decking. It confirms whether a stain is from an active leak or an old, dried event.
Boroscope inspection camera
Lets us see inside wall cavities and tight attic spaces without cutting drywall. We use it to trace water paths behind chimneys and skylights.
Water hose test equipment
Applies controlled water to suspect roof areas one zone at a time. This is the most reliable way to prove the exact entry point of a leak.
Roof moisture survey kit
Includes pin meters and probes for hard-to-reach areas. We use it on flat roofs and around roof penetrations to map moisture patterns.
Drones for roof inspection
Capture high-resolution images of steep or tall roofs without sending a technician up. Useful for initial assessments and for documenting storm damage.
Use cases
When to call for Roof Leak Detection in Covina in Covina
These examples show how the service framework adapts rather than forcing every call through one repair.
Chimney flashing rebuild stops wind-driven leak
A Covina Hills home leaked only during heavy wind-driven rain. Water ran down the chimney and stained the ceiling near the fireplace. The old flashing was rusted and pulling away from the masonry. → We rebuilt the chimney flashing with new ice and water shield, metal counter-flashing, and GAF sealant. A water hose test confirmed no leaks. The homeowner has had two rainy seasons with no drips.
Flat roof ponding repaired in Charter Oak
A flat roof carport in Charter Oak held water after every storm. The membrane had several pinholes and a seam was separating. Water was dripping onto a parked car and the garage ceiling. → We repaired the seam with roofing membrane and sealant, then added a tapered patch to improve drainage. The ponding stopped and the garage ceiling stayed dry through the next rainy season.
Problems we solve
Roof leak problems we solve in Covina
Most Covina roof leaks come from the same handful of failure points. We see them every week and know exactly how to diagnose and fix each one.
Ceiling water stains that keep coming back
We trace the stain back to the roof with a moisture meter and thermal camera. Then we repair the failed flashing or shingle and test the area with water before closing up.
Chimney flashing leaks during wind-driven rain
We remove the old flashing, install new ice and water shield, and rebuild the counter-flashing with roof cement and sealant. We then water-test the chimney from the roof side.
Clogged gutters causing leaks at the fascia
We clear the gutters, check the drip edge, and replace any rotted fascia. If water has entered the attic, we dry and treat the area before repairing the roof edge.
Flat roof ponding after storms
We inspect the membrane, locate low spots, and repair seams with roofing membrane and sealant. If ponding is severe, we recommend a tapered insulation retrofit to improve drainage.
Pricing process
Roof Leak Detection in Covina in Covina pricing
$180 - $850 depending on scope
Roof height and pitch
Steep or tall roofs require more safety equipment and time. A simple single-story ranch is faster to inspect than a two-story home with a 10/12 pitch. This affects the detection fee.
Leak complexity
A single pipe boot leak is easy to find. A leak that only shows up in wind-driven rain may require multiple water tests and attic scans. Complex leaks take longer to diagnose.
Access to attic
If your attic is finished or has limited access, we may need to use a boroscope camera or create a small access point. This adds time but avoids cutting large holes.
