What's Included

Every roof leak detection and repair job includes:

Infrared moisture imaging: locates wet insulation and decking under the roof membrane

Moisture-meter testing: quantifies moisture content at suspect entry points

Attic inspection: backlights the deck for visible water tracks and follows them to the source

Flashing diagnosis: pipe collars, chimney step flashing, valley flashing, dormer counter-flashing

How It Works

Four steps from leak diagnosis through hose-tested repair.

On-Site Leak Diagnosis

Homeowner walkthrough to map where the leak shows inside, attic inspection for water tracks and stained sheathing, then exterior roof walk over the suspect zones above the interior leak. We follow the water from the inside out.

Imaging and Moisture Testing

Infrared thermal scan highlights wet insulation under the membrane. Moisture meter quantifies the wet area at suspect entry points: flashing collars, valley flashings, chimney step flashing, and dormer counter-flashing. The leak source is narrowed before any roof work.

Source Confirmation

Direct hose test on a dry day verifies the exact entry point. Water in, water out, water timed against the interior appearance. Written scope follows with repair, flashing replacement, or section re-lay options sized to the verified source.

Repair and Water-Test Sign-Off

Targeted repair of the leak source with matching shingles or fresh flashing. Hose-test verification before final invoice, so you see the dry interior after the repair. Photo close-out of the repaired area for your records and any insurance claim.

Roof Leak Detection and Repair Questions, Answered

How do you find a leak in a roof?

Roof leaks are located by attic inspection (backlit decking shows water tracks), moisture-meter testing at suspect entry points, and infrared imaging that highlights wet insulation under the membrane. Direct hose testing on a dry day confirms the exact entry once the source area is narrowed.

What is the most common roof leak?

Flashing failure is the most common roof leak source. Pipe collars, chimney step flashing, and valley flashing fail more often than the shingle field itself. Boot collars typically dry-rot within 10 to 15 years; chimney flashing fails when caulk dries and pulls away from masonry.

How much does it cost to fix a roof leak?

Roof leak repair in Monmouth County runs $400-$1,500 for accessible flashing or boot work and $1,500-$5,500 when active leaks behind drywall require decking replacement and underlayment work. Source diagnosis adds $250-$500 when infrared imaging or moisture testing is needed.

Will home insurance cover roof leak repair?

Homeowner insurance typically covers leak-related interior damage if the leak source came from a covered event (wind damage, fallen tree). Wear-and-tear leaks such as boot rot or flashing aging are typically not covered. Photographic evidence of the cause helps the adjuster determine event vs. wear classification.
