# Skylight Installation Toronto: Commercial Skylight Replacement for Offices, Libraries, Retail & Industrial Roofs

Last updated: October 4, 2026 · By The Skylight Installation Toronto Crew

Commercial

[/ →](/)

 skylight replacement in Toronto is the phased removal of failing domes, glass units and atrium panels from offices, libraries, stores and industrial buildings, then installing new units with fresh membrane tie-ins and fall-protection screens while the building stays open. We often time it with a re-roof to share mobilization, and recent work includes a City of Toronto Public Library branch on the Danforth and a $65,000 Vaughan Metropolitan Centre office tower.

## What Commercial Skylight Replacement Involves

Commercial skylights fail at scale. When one dome cracks, the other eleven installed at the same time are usually not far behind. Replacement is about doing them in a sensible order, keeping the building operating and making sure the new units are tied into the roof properly.

We start with a condition survey of every unit, then plan phases around your tenants and any upcoming re-roof. Each unit is removed, the curb is checked, the membrane is tied back in and a fall-protection screen goes on the same day.

## The 5 Commercial Skylight Problems We Replace Most

1.  **Cracked and yellowed polycarbonate domes** on warehouses and retail.
2.  **Wired glass** on older industrial roofs.
3.  **Failed atrium glazing** with fogged or leaking sealed units.
4.  **Rotted wood curbs** under decades of patches.
5.  **Missing fall protection** on units installed before current rules.

| Safety | MOL-standard fall-protection screens |

## Our Commercial Replacement Expertise

We know that the hard part of commercial work is not the skylight, it is the logistics. Who holds the roof warranty, when tenants arrive, where the crane can stand, what the board needs to see. We sort those out before anyone climbs a ladder.

## What Actually Stops Managers From Replacing Skylights

### “Budget is already committed this year.”

In our opinion, a condition survey helps here. We tell you which units are urgent and which can wait for next year’s capital plan.

### “Tenants will complain.”

Phasing and after-hours cutting keep complaints rare.

### “We just re-roofed.”

We tie into new membranes to the roofer’s details without voiding warranties.

### “Paperwork is a nightmare.”

COI, WSIB letters, method statements and closeout docs, all standard.

## Commercial Replacement Timeline

### Survey (Week 1)

Every unit inspected and reported.

### Proposal and Approvals (Weeks 2 to 4)

Phasing plan, permits if needed.

### Phased Replacement

One day to three weeks depending on unit count.

### Closeout

Photos, warranties, documentation.

## Commercial Replacement Cost in Toronto: What Drives the Price

### Number of Units

Larger batches lower the per-unit cost.

### Unit Type

Domes cost less than glass curb-mount or atrium panels.

### Curb Condition

Rotted curbs need rebuilding.

### Membrane Type

SBS tie-ins take more time than TPO.

### Screens

Required on commercial roofs.

### Scheduling

After-hours and weekend premiums are itemized.

## Fixed, Venting or Solar: Choosing Your Skylight Type

Survey in week one, approvals in weeks two to four, phased work on site for one day to three weeks, closeout within a week.

Straight Answers

## Commercial Replacement FAQ: 12 Questions Toronto Clients Ask

### How much does commercial skylight replacement cost in Toronto?

Commercial replacement runs $6,000 to $30,000 CAD for most projects, with larger atria and towers above that. Our Vaughan Metropolitan Centre tower replacement was $65,000. Quotes itemize units, removal, tie-in, screens and any after-hours work.

### Should we replace skylights during a re-roof?

Yes, if the units are more than 15 to 20 years old. Sharing mobilization and doing the tie-in once saves money and avoids cutting into a brand new membrane later.

### Can you replace skylights while the building is open?

Yes. We phase units, schedule noisy work outside business hours and protect the interior below with sealed enclosures.

### Do you replace polycarbonate domes with glass?

Often. Glass lasts longer and stays clear. Polycarbonate still makes sense for hail-prone or impact-risk roofs, and we will recommend whichever fits.

### Will you add fall-protection screens?

Yes. Screens to MOL standard are included on commercial replacements, and many older roofs need them added anyway.

### Do you work with our roofer of record?

Yes. We coordinate tie-in details with your roofer so the membrane warranty stays intact.

### How long does a commercial replacement take?

Single units take a day. Multi-unit projects run over several phases, typically one to three weeks. Our VMC tower project took a week.

### What insurance do you carry?

$5M commercial general liability, $2M property damage and full WSIB, with COI and clearance letters supplied before mobilization.

### Can you give us a condition report first?

Yes. We survey every unit and give you a written replace, repair or monitor recommendation, useful for capital planning.

### Do you handle public buildings?

Yes. Our City of Toronto Public Library branch replacement on the Danforth (2024) was phased around public hours.

### What about sound and hail resistance?

Laminated glass improves STC ratings for quieter interiors, and we can specify hail-resistant glazing on exposed roofs.

### What warranty is included?

Lifetime leak-free warranty on our flashing and tie-in work, plus the manufacturer's product warranty.

Still have a question?

Talk to a crew lead, not a call centre.
