Roof Flashings

Roof Flashing Services

Flashing installation, repair, and replacement around chimneys, vents, skylights, and roof joints — stopping leaks at their most common source before they cause serious damage.

What We Do

Roof Flashing — The Most Overlooked Leak Source

Most roof leaks don’t start in the middle of a shingle — they start at the joints, edges, and penetrations where different surfaces meet. Roof flashing is the metal barrier installed at these vulnerable points to redirect water away and prevent it from seeping into your home.
At Eclat Home, we install, repair, and replace all types of roof flashings for residential and commercial properties across the GTA. Whether you’re dealing with a leaking chimney, a failed vent flashing, or deteriorating step flashings on a roof addition — our certified team diagnoses the problem correctly and fixes it to last.

Flashing Types

Where Flashings Are Used — And Why Each One Matters

Every area where your roof meets another surface needs flashing. Here are the six most critical flashing locations we install and repair.

01
Around the chimney base & sides
Chimney Flashing
The most leak-prone area on any pitched roof. Chimney flashing uses a two-part system — base flashing and counter flashing — to seal all four sides of the chimney where it penetrates the roof surface.
Most Common Leak Source
02
Around plumbing & exhaust vents
Pipe & Vent Flashing
Rubber or metal boot flashings seal around plumbing stacks, exhaust vents, and HVAC pipes that penetrate the roof deck. Rubber boots crack and deteriorate over time — one of the most common sources of small but persistent leaks.
03
Around all four sides of skylight
Skylight Flashing
Skylights require a continuous flashing system around all four sides — with a saddle (cricket) on the uphill side to divert water around the unit. Improperly flashed skylights are a major source of ceiling leaks and interior water damage.
04
Where roof meets a vertical wall
Step & Counter Flashing
Step flashing is installed piece by piece between each shingle course where the roof meets a vertical wall — such as at dormers, additions, or adjacent walls. Counter flashing covers the step flashing and is embedded into the wall above. Together they create a watertight barrier.
05
Where two roof slopes meet
Valley Flashing
Roof valleys collect and channel large volumes of water whenever it rains. Valley flashing — typically a continuous metal sheet — lines the valley to handle this high water volume and direct it cleanly into the eavestroughs without backing up under shingles.
06
Along all roof edges & rakes
Drip Edge Flashing
Drip edge is a metal flashing installed along the entire perimeter of the roof — at eaves and rakes — to direct water off the roof edge and into the gutters rather than running back under shingles or down the fascia board, preventing rot and water infiltration.

Common Problems

Why Roof Flashings Fail

Age & Corrosion

Metal flashings corrode and deteriorate over time — especially in the GTA's freeze-thaw climate. Old flashings crack, separate, and lose their seal without visible warning from ground level.

Thermal Movement

Repeated expansion and contraction from temperature changes pulls flashings loose from their seals and causes the caulking around them to crack — creating water entry points.

Poor Original Installation

Improperly installed flashings are the most common cause of early flashing failure. Incorrect overlap, wrong materials, or inadequate sealing allows water in from the very first rainstorm.

Why Eclat Home

Why Homeowners Choose Eclat Home for Flashing Work

Accurate Leak Diagnosis Flashing leaks are notoriously difficult to trace — water often travels far from the entry point. Our team pinpoints the exact source before any work begins.

Quality Materials We use aluminum, galvanized steel, and lead-free materials appropriate to each application — properly sized, overlapped, and sealed for long-term performance.

Comprehensive Inspection When fixing one flashing, we inspect all surrounding flashings on the same visit — identifying any other vulnerable points before they become the next leak.

How It Works

Our Flashing Repair & Installation Process

01.

Inspection & Diagnosis

We conduct a thorough roof inspection — checking all flashings, seals, and joints to pinpoint the exact leak source and identify any other vulnerable areas.

02.

Honest Assessment

We explain exactly what needs to be repaired or replaced, why, and what the risks are of leaving it — giving you a clear, transparent quote before work begins.

03.

Repair or Replacement

Deteriorated or failed flashings are removed and replaced with properly sized, correctly overlapped metal flashings — sealed with professional-grade sealant.

04.

Water Test & Verification

After installation, we verify the repair with a water test to confirm the leak is resolved — and inspect surrounding flashings one final time.

Roof Flashings — Common Questions

Common signs include water stains on ceilings or walls near chimneys, skylights, or dormers; rust streaks on exterior walls; visible gaps or cracks around chimney bases; or water in the attic after rain. A professional inspection is the only way to accurately diagnose the source.

Quality metal flashings typically last 20–30 years. However, the sealants used around flashings deteriorate faster — usually every 10–15 years — and should be inspected and resealed regularly.

Often the flashing itself is intact but the sealant has failed — in which case resealing is sufficient. If the metal is corroded, cracked, or improperly installed, full replacement is the correct solution. We assess and give you an honest recommendation.

Chimney flashings are the most common source of flashing-related leaks, followed by pipe/vent flashings and valley flashings. All are areas where two surfaces meet — creating natural water collection points.

We always inspect all flashings on the same visit. Finding one failed flashing usually means others nearby are at a similar stage of deterioration — catching them early saves a repeat service call.

We use aluminum, galvanized steel, and where appropriate, copper flashings — selected based on the application, surrounding materials, and budget. All installations use professional-grade waterproof sealants.
