What Our Roof Leak Detection Includes
Every detection visit covers the full diagnostic process, from attic to roof surface.
Work order
Roof Leak Detection- Attic Moisture Inspection: We inspect the attic with a moisture meter and infrared thermal imaging camera, checking rafters, decking, and insulation for water trails. This step narrows the search area before we climb onto the roof, saving time and reducing unnecessary roof traffic.
- Roof Surface Examination: We walk the roof and check flashing, pipe boots, valleys, vents, and shingle courses for damage. Lifted shingles, cracked boots, and failed sealant are documented with photos. This is where most leaks are visually confirmed.
- Controlled Hose Test: We run water over suspect areas while a second technician watches from the attic with the thermal camera. This reproduces the leak on demand and confirms the exact entry point. Hose testing is the most reliable way to prove a leak source.
- Written Findings Report: You receive a written report with photos of the entry point, the water trail, and any damaged materials. The report includes the cause, the recommended repair, and a flat price. You keep a copy for your records or your insurance claim.
- Flat Repair Quote: If the fix is straightforward, we quote a flat price on the spot and can often complete it the same visit. Larger repairs, like sheathing replacement or full flashing rebuilds, get a written scope and a scheduled return date.

What Roof Leak Detection in San Marino, Texas Involves
Finding the leak is the whole job. Repair the wrong spot and the water keeps coming. We trace it, prove it, and only then quote the fix.
Roof Leak Detection in San Marino, Texas is a diagnostic service that traces water intrusion from the ceiling stain back to its actual entry point on the roof. Water rarely drips straight down; it follows roof decking, underlayment, and rafters before it shows up on your drywall. We start with an attic inspection, then move to the roof surface to check flashing, pipe boots, valleys, and shingle courses. A moisture meter confirms wet decking, and an infrared thermal imaging camera reveals temperature differences where water is hiding behind the ceiling.
San Marino sits in a hail and wind corridor, so shingle blow-off and flashing failure are common after spring storms. Many homes here have architectural shingles that look fine from the street but have cracked pipe boots or lifted step flashing letting water in at the chimney.

How Roof Leak Detection Runs in San Marino
San Marino sits in a hail and wind corridor, so most of the leaks we find here start with storm damage: lifted shingles, cracked pipe boots, and pulled flashing.
Monte Vista
Older homes with original clay tile and complex roof lines. Tile underlayment failures are common here, and leaks often show up far from the actual entry point.
Stone Oak
Larger homes with architectural shingle roofs and multiple valleys. Hail bruising and valley flashing failures are the most frequent leaks we find.
Beacon Hill
Historic homes with steep roofs and original wood shake or slate. These need careful handling and matching materials for any repair.

PhotoCeiling Stain Traced to Cracked Pipe Boot
Before: A homeowner in Beacon Hill had a growing brown stain on the hallway ceiling after every rain. Two previous companies had replaced shingles with no result. The attic showed wet decking but no obvious entry point from inside.
After: Our hose test confirmed a cracked pipe boot 12 feet from the stain. We replaced the boot and collar, resealed the base, and retested. The stain stopped growing immediately, and the homeowner repainted the ceiling two weeks later.
Flat Roof Seam Leak on Commercial Building
Before: A property manager in Stone Oak had stained ceiling tiles in three tenant spaces. The TPO membrane looked intact from the ground, but water was ponding near a clogged roof drain after every storm.
After: Electronic leak detection found two pinholes in a seam near the drain. We patched with matching membrane, cleared the drain, and retested with water. No new ceiling stains were reported in the following months.
Hail Damage Repaired Before Next Storm
Before: After a spring hail storm, a homeowner in Alamo Ranch noticed granules in the gutters but no active leak. An inspection found hail bruising on the south-facing shingles and a cracked vent boot that was just starting to leak.
After: We documented the hail damage with photos, replaced the cracked boot, and replaced four bruised shingles. The homeowner filed an insurance claim with our report and had the roof repaired before the next storm.

What San Marino Customers Say
We had a ceiling stain that three other companies could not explain. The technician ran a hose test while his partner watched the attic with a thermal camera and found a cracked pipe boot in about 40 minutes. He showed me the photos, replaced the boot the same visit, and the stain stopped growing. That was in March and we have had no water since.
I manage six commercial buildings with flat TPO roofs. Their electronic leak detection found a pinhole seam leak that had been ponding water for months. They patched it with matching membrane and cleared the clogged roof drain that caused the backup. The written report with photos made my insurance claim easy.
After the last hail storm we had water coming through the attic. They came out the same day, tarped the roof, and documented the hail damage for our insurance. The repair crew replaced four shingles and resealed the flashing two days later. Flat price, no surprises, and the ceiling is dry.
