When It’s Time to Replace Your Flat Roof

When patching no longer keeps up, replacement is the better value. We remove the old roofing down to the deck, replace damaged sheathing, correct ponding and drainage, and install a new heat-welded SBS torch-on system with new flashings, so you start fresh with decades of protection.

What You Gain From

a Torch-On Re-Roof

End the Patch-and-Leak Cycle

If you are calling for repairs every season, a new membrane stops the spending and the stress with one roof that simply works.

Fix Hidden Deck Damage

Tear-off lets us find and replace soft or rotted sheathing caused by years of slow leaks, before it becomes a structural problem.

Correct Ponding & Drainage

Many older flat roofs hold water. A re-roof is the time to add slope, crickets and new drains so water finally runs off.

Upgrade Old Tar & Gravel

Replacing an old tar-and-gravel or rolled roof with modern SBS gives you a lighter, longer-lasting and easier-to-maintain roof.

Signs Your Flat Roof Needs Replacing

Cracked or Brittle Membrane

When the surface is cracking, alligatoring or brittle to the touch, the membrane has reached the end of its life.

Leaks in Several Places

One leak is a repair. Leaks in different rooms or after every storm point to a roof that is failing overall.

Soft Spots or Ponding Water

Spongy areas underfoot or water that sits for days usually mean wet insulation or deck damage underneath.

Roof Over 20 Years Old

Most torch-on and older flat roofs are near the end of their service life by 20-25 years, even if they look okay.

Our Torch On Roofing Replacement Process

01

Roof Assessment & Core Check

We inspect the roof and, where needed, cut small test cores to check for wet insulation and deck damage before quoting.

02

Tear-Off & Deck Repair

We remove the old roof down to the deck, replace damaged sheathing and correct drainage so the new membrane goes onto a sound, properly sloped surface.

03

Install the New System

We install a new base sheet and granulated SBS cap sheet, heat-welded with overlapping seams and new flashings at every edge.

04

Cleanup & Warranty

Old roofing is hauled away, the site is magnet-swept for nails, and your new manufacturer warranty is registered.

SBS Modified Bitumen
APP Modified Bitumen
Fiberglass Reinforced Membranes
Polyester Reinforced Membranes
Granulated Cap Sheets

SBS Modified Bitumen

★ BEST FOR THE OKANAGAN

Most of our Kelowna re-roofs move to a two-ply SBS system, which handles freeze-thaw and summer heat far better than older flat roof materials.

20+ Years

APP Modified Bitumen

When replacing roofs with heavy sun exposure and little foot traffic, APP can be a good fit. We will help you decide.

20+ Years

Fiberglass Reinforced Membranes

On commercial re-roofs that must meet fire code, we upgrade to fiberglass-reinforced membranes with Class A fire ratings.

25+ Years

Polyester Reinforced Membranes

If your old roof carries equipment or a deck, we re-roof with polyester-reinforced membranes for better puncture resistance.

20+ Years

Granulated Cap Sheets

Every replacement is finished with a granulated cap sheet, adding UV protection and years of extra service life.

Why Choose GVRD for Torch-On Replacement

566

Honest Repair vs. Replace Advice

We only recommend replacement when it is the better value. If your roof still has good years, we will tell you.

No Surprises on Deck Repairs

Our quotes explain how rotten sheathing is priced, so you know the cost before we start, not after tear-off.

Weather-Safe Scheduling

We only open as much roof as we can close the same day, so your home is never left exposed overnight.

Clean, Careful Crews

We protect landscaping, haul away all debris and sweep for nails before we leave.

Long-Term Warranty

Your new roof comes with manufacturer material coverage plus our workmanship warranty.

I had an excellent experience with GVRD Roofing. From the initial inspection to the completed project, the team was professional, knowledgeable, and easy to work with. They communicated clearly throughout the process, showed up when they said they would, and the quality of the workmanship was outstanding. It's clear they take pride in their work and genuinely care about delivering a roof that's built to last. The crew kept the site clean, worked efficiently, and made the entire experience stress-free. If you're looking for a reliable roofing company for residential or commercial roofing, roof repairs, or metal roofing, I highly recommend GVRD Roofing. I wouldn't hesitate to use them again for future projects.

We are a townhouse strata community in West Vancouver, BC, and GVRD recently completed our renewal project involving 12 flat garage roofs (2025). After getting quotes from three companies, we chose GVRD because of their shorter lead time, reasonable pricing, and strong warranty terms—and it turned out to be the best decision. The workmanship was excellent, the team was highly experienced, and they used advanced technology and equipment throughout the process. Everything was efficient and well‑organized, and their customer service was outstanding. Since completion, the new roofs have already been tested by several storms and atmospheric river events, and they have proven to be strong and reliable. In addition, GVRD provided valuable support for our upcoming roof and deck maintenance planning for the next 3–5 years. They even used drone technology for detailed measurements and assessments, which was extremely helpful. Highly recommended.

GVRD Roofing was extremely responsive, professional, and quick to address everything that came up. Their communication, service, and attention to detail made the whole experience smooth and stress-free. We highly recommend GVRD Roofing for anyone in Vancouver looking for reliable flat roof installation services. Thank you!

I had Dan came over to look at a water pooling and minor leak on my torch-on flat roof. He gave me a quote, came back as agreed. The roof was fixed, flattened and new drain was added. I am happy with the work and the cost was reasonable. They fixed what was needed and it was done in a timely manner. I will be looking for them to do regular inspections in the future.

Torch On Roofing Questions Answered

Most residential flat roofs take 1-3 days, depending on size and how much deck repair is needed. Larger roofs are done in sections.
We usually recommend a full tear-off so we can check the deck and fix drainage. Layering over an old roof can trap moisture and hide damage.
We replace damaged sheathing as part of the job at the unit price listed in your quote, and we show you photos before covering it up.
Cost depends on roof size, tear-off layers, deck repairs, drains and access. After an inspection we give you a detailed written quote. Building new? See new torch-on installation or all torch-on roofing services.
If the membrane is brittle or leaking in several places, repairs only buy a short time. Replacement resets the clock with a roof built to last 20-30 years. If your roof still has good years left, see torch-on roof repair.
Yes. We open only what we can finish and seal the same day, and we cover the work area if the weather changes.
