Finding the Leak Source on Highland Park Roofs
A roof that has been patched over the years can hide several possible entry points: repaired valleys, an extra layer of shingles, and flashing that has shifted or corroded since it was installed. Pinpointing where water actually enters is the first step, because the ceiling stain and the breach point are rarely directly above each other. Roof Replacement Inc traces the path before any repair work begins. Call (213) 364-3979 to schedule a leak assessment.
- ✓Visual inspection of field shingles, ridges, and hips
- ✓Valley and hip flashing checked for gaps or corrosion
- ✓Pipe boots, vents, and skylights probed for failed seals
- ✓Chimney and parapet flashing examined on older masonry
- ✓Flat-roof membrane surface checked for blisters or open seams
- ✓Interior attic inspection to trace water travel path

Shingle and Roof Valley Leak Repair in Highland Park
On a composition shingle roof in Highland Park, the valleys where two roof planes meet are among the first places to fail. Cracked or missing shingles, lifted tabs, and deteriorated valley metal all create entry points that worsen with each rain season. Roof Replacement Inc replaces damaged shingles, resets or replaces valley flashing, and reseals penetrations so the repair holds rather than just delays the next leak. Call (213) 364-3979.
- ✓Damaged or missing shingles replaced to match existing field
- ✓Open or corroded valley metal removed and reset
- ✓Woven and cut valley configurations both addressed
- ✓Step flashing along dormers and additions reseated or replaced
- ✓Exposed nail heads and lifted tabs resealed
- ✓Synthetic underlayment patched or extended beneath repair area

Flat and Low-Slope Leak Repair in Highland Park
Flat-roof additions and rear structures need a different repair approach than pitched shingle work. Torch-down modified bitumen and TPO membranes develop leaks at seams, around drains, and at the transition where the flat section meets a vertical wall or parapet. Roof Replacement Inc patches open seams, resets drain collars, and reseals wall terminations on these systems. Call (213) 364-3979 to discuss your flat-roof leak.
- ✓Open or lifted seams heat-welded or cold-adhesive bonded
- ✓Drain collar and overflow drain flashing reseated
- ✓Parapet cap and wall termination flashing resealed
- ✓Blistered or bubbled membrane sections cut out and patched
- ✓Roof coating applied over repaired area where appropriate
- ✓Ponding water areas noted and drainage slope assessed

Roof Vent and Flashing Leak Repair in Highland Park
Pipe boots, exhaust vents, and the flashing around chimneys and skylights are the most common single-point leak sources on Highland Park homes. Rubber pipe boots crack with age and UV exposure, and chimney flashing on older masonry structures can separate from the mortar bed over time. These are targeted repairs: replace the boot, reset the flashing, and reseal the penetration without disturbing the surrounding field. Call (213) 364-3979.
- ✓Cracked or split rubber pipe boots replaced
- ✓Lead or aluminum flashing around chimneys reseated and sealed
- ✓Skylight curb flashing inspected and resealed
- ✓Exhaust vent collars checked and secured
- ✓Ridge vent end caps and seams resealed
- ✓All penetration repairs sealed with compatible roofing caulk or mastic
