Roof Leak Repair

Finding the Leak Before It Finds You

A roof leak rarely shows up directly under the hole. Water travels along rafters, sheathing, and insulation before it drips onto your ceiling three rooms away from the actual entry point. That is why leak repair starts with detection, not guesswork. Our crews use moisture meters, infrared imaging, and controlled water testing to trace the leak back to its source, then fix the cause — not just the symptom.

We repair roof leaks on homes, townhomes, condos, and light commercial buildings. Whether the leak appeared after a storm, showed up slowly over months, or opened up suddenly when the wind shifted, we find it and fix it so it does not come back.

Common Sources of Roof Leaks

Most leaks originate at penetrations, transitions, or low points where water can pool or back up.

• Flashing failures — chimneys, skylights, walls, and vent pipes where step flashing, counter flashing, or boot seals have deteriorated
• Valley leaks — where two roof planes meet and water concentrates; worn underlayment or corroded valley metal lets water through
• Pipe boot deterioration — the rubber collar around plumbing vent stacks cracks and shrinks over time
• Shingle damage — lifted, cracked, or missing shingles expose the underlayment and deck
• Ice dams — in cold climates, trapped water backs up under shingles at the eaves
• Clogged or damaged gutters — water overflows behind the fascia and enters the attic or wall cavities
• Deck rot — compromised sheathing that lets water pass through even when the roofing material looks intact

How We Find the Leak

We use a layered approach to locate the exact entry point.

1. Visual inspection — we walk the roof and attic, looking for water stains, damaged shingles, deteriorated sealant, and visible gaps at penetrations
2. Moisture mapping — handheld moisture meters identify wet insulation and sheathing inside the attic or ceiling cavity
3. Infrared scan — thermal cameras reveal temperature differences that indicate trapped moisture, even when no stain is visible
4. Water testing — when the source is unclear, we isolate sections and run controlled water flow to reproduce the leak
5. Source confirmation — once identified, we mark the exact spot and explain the repair before any work begins

How We Fix the Leak

The repair depends on the source. We do not use generic roof sealant as a catch-all fix.

Leak source	Repair method
Flashing at chimney or wall	Remove old flashing, install new step and counter flashing with proper sealant
Pipe boot failure	Replace rubber boot and metal collar with a new UV-resistant unit
Valley leak	Remove valley shingles, replace valley metal or membrane, re-shingle
Lifted or missing shingles	Replace damaged shingles, re-seal exposed nail heads
Ice dam damage	Repair deck and underlayment, add ice barrier, address ventilation
Skylight leak	Replace skylight flashing kit or install new skylight if unit is failed

We never just smear sealant over a leak and call it done. Every repair addresses the root cause so the leak does not return next season.

Leak Repair Costs

Costs vary by source, accessibility, and extent of damage.

Repair type	Typical range
Pipe boot replacement	$150 – $400
Flashing repair (chimney, wall)	$400 – $1,200
Valley repair	$500 – $1,500
Shingle replacement (small area)	$200 – $600
Leak detection only	$200 – $500
Ice dam damage repair	$800 – $2,500

Every repair is backed by a written workmanship warranty. If the leak returns within the warranty period, we come back and fix it at no charge.

Emergency Leak Response

When water is actively entering your home, speed matters. We offer same-day and next-day emergency leak response in most areas. We will tarp the roof if needed to stop the immediate water intrusion, then schedule the permanent repair as soon as conditions allow.

While you wait for us:

• Place buckets under active drips to protect flooring
• Move furniture and valuables away from the wet area
• If safe, place a tarp over furniture or lay plastic sheeting
• Do not attempt to climb on the roof yourself — wet roofs are dangerously slick

Preventing Future Leaks

The best leak is the one that never happens.

• Inspect the roof and attic twice a year, spring and fall
• Clean gutters and downspouts so water flows freely away from the roof
• Trim branches that rub against or overhang the roof
• Re-seal pipe boots, flashing joints, and vent caps before the rubber and sealant dry out
• Address ice dam risks early with proper insulation and ventilation
• Book a professional inspection after any severe storm

What to Expect From Our Service

From the first call to the final walkthrough, we keep you informed. We show up on time, we explain what we find, we give you a written estimate before any work begins, and we clean up thoroughly when the repair is done. Our crews are licensed, insured, and trained to fix leaks the right way — at the source, not over it.

Common Roof Leak Locations

Location	Why it leaks	Typical repair
Around chimneys	Step flashing separation, cracked counter flashing	Re-flash chimney, replace counter flashing
At pipe boots	Rubber collar cracks, sealant failure	Replace pipe boot collar
In valleys	Debris buildup, worn valley flashing	Clean valley, re-flash, or install ice and water shield
At skylight edges	Failed skylight flashing, cracked sealant	Re-flash skylight or replace unit
Along ridge cap	Dried sealant, lifted ridge cap	Re-seal or replace ridge cap
At wall transitions	Step flashing pulled away from wall	Re-flash wall transition
In flat roof seams	Seam separation, adhesive failure	Re-weld seams or patch membrane

Understanding where leaks originate helps you describe the problem accurately when you call. Most leaks are not at the visible water stain — water enters at one point and travels along rafters or sheathing before dripping down into the living space. The entry point is usually higher and farther from the stain than you expect.

Leak Repair Cost Ranges

Repair type	Typical cost
Pipe boot replacement	$150 – $350
Flashing re-seal or replacement	$200 – $600
Shingle replacement (small area)	$200 – $500
Valley repair	$400 – $1,000
Skylight re-flash	$300 – $800
Chimney re-flash	$500 – $1,500
Flat roof patch	$300 – $800
Widespread leak investigation	$500 – $1,500

The cost of a roof leak repair depends on the source, the accessibility of the damaged area, and the roofing material involved. Simple repairs like pipe boot replacement are quick and affordable. Complex leaks at valleys, chimneys, or wall transitions require more time and materials. We provide a written estimate before any work begins.
