# Skylight Flashing Repair in Toronto, ON | Shingle, Metal, Tile & Brick-Abutting Roofs

Skylight Installation Toronto

[/ →](/)

 rebuilds and repairs skylight flashing on shingle, metal, tile, cedar shake and brick-abutting roofs across Toronto and the GTA. We strip the failed flashing, assess deck and curb condition, install new Grace Ice & Water Shield around the perimeter, then set a pre-engineered Velux EDL, EDM, EDW or Fakro ELV flashing kit matched to your roof type and pitch.

Flashing repairs run $400 to $1,800 depending on roof type, access and whether the curb needs rebuilding, with no-nail step-flashing on tile and copper hand-forming on heritage brick abutments. Every repair is backed by OBC 9.26 compliance, Velux Certified Installer status since 2004, and a written workmanship warranty, since nine times out of ten failed flashing is where the previous installer cut the corner.

Skylight flashing layers: ice and water shield, step flashing, head flashing and apron

## Why Flashing Is Where Most Skylights Fail

Nine times out of ten, a skylight stain at the curb is a flashing problem. Flashing is the layered metal system that sheds water around the skylight: an apron at the bottom, step flashing up the sides woven into the shingles, a head flashing at the top, and underneath it all, ice and water shield sealed to the curb.

When any one of those layers is missing, rusted, reversed or replaced with caulk, water gets in. We see every version of it. Flashing repair means stripping back to the deck and rebuilding the layers in the right order.

## The 5 Flashing Failures We Fix Most Often

1.  **Missing head flashing**, so water from above runs straight under the top of the unit.
2.  **Rusted step flashing** on 25+ year-old skylights.
3.  **Caulk instead of flashing**, especially on brick-abutting skylights.
4.  **No ice and water shield** under the flashing.
5.  **Reused flashing after a re-roof.**

## Residential Flashing Repair

### Asphalt Shingle Roofs

The most common roof in the GTA. Velux EDL kits or step flashing. We pair the kit with full ice-and-water shield around the curb, lapped shingle-style, so a $185 EDL reinstall outlasts a $300 caulk-and-go patch within a single freeze-thaw cycle.

### Metal Roofs

Velux EDW kits and custom-bent trim for standing seam. Standing seam and ribbed panels can take a few extra hours because the flashing tucks under the seam clips. EDW kits are commonly $120 a meter. We hand-form for the corners.

### Tile and Slate Roofs

Hand-formed flashing, often copper on heritage homes. Copper runs hand-formed in the truck and on the roof to match the slate profile. Copper is much heavier than aluminum but lasts more than 50 years.

### Skylights Against Brick Walls

Reglet counter-flashing cut into mortar joints. We cut a reglet groove into the mortar and tuck the counter-flashing into it, then seal. Surface-mounted strips caulked to brick fail within a few seasons.

### Low-Slope Roofs

Curb-mount details and extended membrane underlayment. Curb-mount units need extended membrane up the curb at least 4 inches. Membrane is torched or cold-applied over the existing roof.

### Skylights Near Valleys

Crickets and extended flashing so valley water is diverted. Crickets divert snow and water around the unit. The cricket itself is often $200 to $400 in sheet metal.

### Chimneys Next to Skylights

Shared counter-flashing details done properly. Shared counter-flashing is detailed to lap correctly around both elements. Brick reglet cutting is often the same crew doing both.

## Commercial Flashing Repair

### Curb-Mount Units on Membrane Roofs

Membrane re-tie and new metal cap flashing. Curb-mounts on flat membrane need the cap flashing pulled, membrane re-tied to the curb, and cap reinstalled. Often staged around rain windows.

### Retail Domes

Resealing and new cap flashing between replacement cycles. Resealing and new cap flashing keeps domes alive between full replacement cycles. Cap flashing runs from $300 to $600.

### Mixed-Use Buildings

Brick parapet skylights with reglet details. Brick parapet skylights need reglet counter-flashing at the parapet tie-in. We coordinate with other trades for safe roof access.

### Warehouses

Aluminum cap flashing over raised curbs. Aluminum cap flashing over raised curbs is standard 0.032 aluminum brake-formed. The unit price drops with quantity.

## Specialty Flashing Work

### Copper Flashing

For slate and heritage roofs. Copper flashing is hand-formed on the roof to match the slate course. Copper is heavy and expensive, $40-70 a foot, but it lasts the life of the roof.

### Brick Reglet Counter-Flashing

For party walls and chimneys. We cut a reglet into the mortar, never the brick face, and tuck the counter-flashing inside. Sealed with masonry caulk, not silicone.

### Cricket Flashing

Above wide skylights to divert snow. Crickets are 4 to 8 inches tall depending on the skylight width. Sheet metal bent to match the roof pitch and lapped under the shingles above.

### Factory Kit Upgrades

Replacing improvised flashing with a pre-engineered kit. We swap improvised flashing for a Velux EDL, EDM or EDW kit matched to the unit and roof. EDL kits from $185, EDW up to $385.

## Flashing Materials

| Roof type | Flashing system |
| --- | --- |
| Asphalt shingle | Velux EDL kit or aluminum step flashing |
| Tile / profiled | Velux EDW kit |
| Low profile | Velux EDM kit |
| Slate / heritage | Hand-formed copper |
| Brick-abutting | Reglet counter-flashing |
| Membrane | Aluminum cap flashing over membrane tie-in |

All over Grace Ice & Water Shield, with Grace Vycor at corners.

## Our Flashing Expertise

We photograph every flashing layer before it is covered, so you can see the work, not just trust it. Twenty years of re-flashing other people’s skylights taught us exactly where shortcuts happen.

## What Actually Stops Homeowners From Re-Flashing

### “Can’t you just seal the gap?”

In our opinion, sealant on flashing is a bandage. It cracks within a couple of Toronto winters and hides the real problem. A proper re-flash strips back to the deck and rebuilds the layers in order, $400 to $1,200.

### “I’d rather replace the whole skylight.”

If the unit is sound, re-flashing costs a fraction and lasts as long. A full replacement runs $1,400 to $3,800 installed, so re-flashing makes sense when the glass and frame are still good.

### “The roofer said it’s fine.”

If it stains after rain, it is not fine. We test it with a hose on the curb before quoting. If the stain is gone after a dry spell, the leak is almost always flashing, not glass.

### “It’s a weird roof.”

Brick walls, slate, metal. We hand-form for anything a kit does not fit. Hand-formed copper and reglet counter-flashing are routine work for us.

## Flashing Repair Timeline

### Inspection

Same-day or next-day visit. We check the curb, lift a few shingles and test for soft wood before quoting. Photographs of every layer go in the quote packet.

### Quote

Kit or hand-formed, itemized. Itemized quote with kit cost, labour, ice and water shield and any curb repair as separate lines. Permit is not a line because flashing repair does not need one.

### Repair

Two to five hours. Old flashing stripped, ice and water shield replaced, new flashing lapped in the right order. Most GTA asphalt shingle flashing repairs are done before lunch.

### Test

Hose test and photos. We hose-test the curb before leaving the roof and re-check the interior after the next rain. Photos of every covered layer get emailed that night.

## Skylight Flashing Repair Cost in Toronto: What You Are Paying For

### Removal of Old Flashing

Careful work around shingles. We lift, not tear, the surrounding shingles so the re-roof bill stays where it belongs. Stripped flashing goes to the metal recycler.

### Ice and Water Shield

Never skipped. Grace Ice & Water Shield, two layers around the curb. Vycor at the corners. OBC 9.26 good practice and the only way flashing lasts in a Toronto winter.

### Flashing Kit or Metal

$185 to $385 for kits, more for copper. Velux EDL is $185, EDW is closer to $300, EDM is about $260. Copper runs $40-70 per foot hand-formed on the roof.

### Labour

Mostly roof time. Labour is mostly roof time: strip, prep, install, lap, test. Two-person crew, half-day to full day depending on access.

### Brick Work

Reglet cutting and sealing. Reglet cutting with a diamond blade, never hammer-and-chisel. Tuck-pointed after the counter-flashing is set. Reglet jobs add $400 to $600 to the line.

### Curb Repair

Only if rot is found. Curb rot gets quoted as a separate line so the homeowner can see it before any wood is cut. Curb repair typically adds $200 to $500.

Field-Tested Workflow

## How Our Flashing Repair Process Works, 5 Steps

The same five steps on every job, whether it is one skylight over a Leaside bathroom or a warehouse full of bays.

1.  1
    
    ### Inspect the Layers
    
    We look at the head, sides and apron, lift a few shingles and check the curb for soft wood.
    
2.  2
    
    ### Kit or Hand-Formed?
    
    Factory kit where one fits, hand-formed metal for odd sizes, heritage roofs and brick walls. Itemized quote.
    
3.  3
    
    ### Honest Line Items
    
    Kit, labour and any curb repair on separate lines. Some installers over-charge for permits and extras thinking homeowners wont check other quotes.
    
4.  4
    
    ### Strip + Rebuild
    
    Old flashing out, fresh ice and water shield, new flashing lapped shingle-style, then a hose test. Checked against our founder's flashing checklist.
    
5.  5
    
    ### Done Properly
    
    Photos of every layer before it was covered, and a warranty that means something.

Straight Answers

## Flashing Repair FAQ: 12 Questions Toronto Clients Ask

### How much does skylight flashing repair cost in Toronto?

A flashing re-install runs $400 to $1,200 CAD per skylight. Factory kit upgrades add $185 to $385 for the kit, and brick reglet counter-flashing runs $600 to $1,200.

### How do I know if my skylight flashing has failed?

Stains at the top or sides of the shaft after rain, rust on the metal, caulk smeared over joints, lifted shingles around the curb and drips that come with wind-driven rain are the usual signs.

### What is the difference between a flashing kit and step flashing?

A factory kit like the Velux EDL is a set of pre-engineered pieces designed for that skylight and roof type. Step flashing is individual L-shaped pieces woven with each shingle course. Both work when installed right.

### Which Velux flashing kit do I need?

EDL for asphalt shingles and thin roofing, EDW for thicker profiled roofing like tile and some metal, and EDM for low-profile roofing. We match by roof type and unit size.

### Can you flash a skylight against a brick wall?

Yes. We cut a reglet groove into the mortar and fit counter-flashing into it, then seal. Surface-mounted strips caulked to brick fail quickly.

### Does flashing repair need a permit?

No. It is a roofing repair with no structural change.

### Can you re-flash without replacing the skylight?

Yes, if the unit and curb are sound. That is the most common flashing job we do.

### How long does a flashing repair take?

Two to five hours for most residential skylights.

### Will you use ice and water shield?

Always. Grace Ice & Water Shield goes around the full curb before the flashing, as OBC 9.26 good practice.

### Do you repair flashing on slate and heritage roofs?

Yes, often with copper flashing formed by hand to match the roof.

### My roofer just re-roofed and the skylight leaks. Why?

The old flashing was probably reused or the underlayment was skipped. A new kit usually solves it.

### Do you warranty flashing repairs?

Yes. Flashing we rebuild gets our leak-free warranty in writing.

Still have a question?

Talk to a crew lead, not a call centre.
