What Is a Torch-On Roof?
A torch-on roof is a waterproof roofing system made from modified bitumen membranes. During installation, qualified roofing contractors use controlled heat from a roofing torch to bond the membrane to a suitable prepared surface or underlying membrane layer.
Torch-on roofing membranes are commonly reinforced with polyester or fibreglass to improve strength and dimensional stability. The modified bitumen material provides flexibility, allowing the roofing system to accommodate normal temperature changes and building movement.
Depending on the roof design, torch-on systems may use one or more membrane layers over a suitable base. Properly installed overlaps and flashing help create a continuous waterproof barrier.
Torch-on roofing is commonly used for:
- Residential flat roofs and low-slope roofing sections
- Commercial buildings and retail properties
- Garages and home additions
- Apartment buildings and strata properties
- Roofs requiring modified bitumen waterproofing
Because torch-on installation involves an open flame, the roofing method must be appropriate for the building's construction and fire-safety requirements. All Coast Roofing assesses the existing roof before recommending a suitable installation method.

Professional Torch-On Roofing Services in Vancouver
All Coast Roofing provides torch-on roofing services for property owners dealing with aging roof membranes, water leaks, and new roofing projects.
Our team evaluates the roofing surface, drainage system, and existing materials before recommending repairs or replacement.
Torch-On Roof Installation Vancouver
Proper torch-on roof installation is essential for protecting a building from water infiltration. The roofing membrane must be installed on an appropriate substrate, with careful attention to overlapping seams, roof edges, drains, and penetrations.
Before beginning a torch-on roofing installation, our contractors assess the roof's structure, slope, and existing materials to determine whether the proposed system is suitable.
Installation work may include:
- Inspecting and preparing the roof surface
- Removing damaged materials when necessary
- Installing an appropriate base layer
- Applying the modified bitumen roofing membrane
- Sealing seams and flashing connections
- Inspecting the completed roofing system
Roofing materials and installation methods depend on the building's construction and the specified membrane system.
If you are constructing a new building or updating an existing roof, our new roof installation services can help you plan the project.
Torch-On Roof Repair Vancouver
Torch-on roof membranes can develop damage over time due to weather exposure, aging materials, foot traffic, or deterioration around roof penetrations.
Our torch-on roof repair services in Vancouver focus on identifying the source of leaks and assessing the condition of the surrounding roofing system.
Common torch-on roof repair work includes:
- Repairing cracks and punctures in roofing membranes
- Addressing loose or deteriorated membrane seams
- Repairing damaged flashing around vents and skylights
- Investigating water infiltration around roof drains
- Replacing localized sections of damaged membrane
- Assessing recurring ponding water and drainage problems
The appropriate repair depends on the extent of the damage and the condition of the existing membrane. In some situations, a localized repair can restore waterproofing. More extensive deterioration may require partial or complete roof replacement.
If your roof is leaking, contact All Coast Roofing for professional roof repair in Vancouver.
Torch-On Roof Replacement Vancouver
Torch-on roof replacement may be necessary when the existing roofing system has reached the end of its service life or experienced widespread membrane damage.
Older roofing systems may develop cracking, open seams, repeated leaks, or moisture problems beneath the membrane. When repairs can no longer address the underlying issues, replacement may be the more practical long-term option.
During a torch-on roof replacement, All Coast Roofing assesses the existing membrane, underlying materials, roof deck, and drainage system.
Depending on the roof's condition, replacement work may involve removing old roofing materials, repairing damaged sections of the deck, installing appropriate insulation, and applying a new membrane system.
We also examine flashing, drains, and roof penetrations because these components are important to the performance of the replacement roof.
For larger properties, learn more about our commercial building roof replacement services.
Advantages of Torch-On Roofing
Torch-on roofing is a practical option for many flat and low-slope buildings in Vancouver. Its performance depends on the selected materials, installation quality, drainage, and ongoing maintenance.
Reliable Waterproofing
One of the main advantages of torch-on roofing is its ability to create a continuous waterproof membrane.
Properly bonded seams and carefully detailed flashing help prevent rainwater from entering the roofing system.
This is particularly important in Vancouver, where frequent rainfall increases the need for dependable roof waterproofing.
Durability in Changing Weather
Modified bitumen membranes are designed to remain flexible during normal temperature changes.
This flexibility helps the material accommodate expansion and contraction while maintaining its waterproofing function.
Appropriate membrane selection and installation are important for protecting roofs exposed to changing weather conditions.
Suitable for Flat and Low-Slope Roofs
Torch-on roofing is commonly used on buildings with low-slope roof designs where effective waterproofing is essential.
These roofs require properly designed drainage because rainwater does not run off as quickly as it does on steeper roofing surfaces.
Torch-on systems can provide reliable protection when the roof has suitable slope, drainage, and membrane detailing.
Repairable Roofing Membranes
Localized damage to a torch-on roof can sometimes be repaired using compatible modified bitumen materials.
Professional repairs may help extend the service life of a roofing system when the surrounding membrane remains in good condition.
However, widespread deterioration or trapped moisture can make replacement necessary.
Modified Bitumen Roofing Membranes
Modified bitumen is the primary waterproofing material used in torch-on roofing systems.
The material combines asphalt with polymers that improve flexibility and performance. Roofing membranes are manufactured in sheets and may include reinforcing layers for additional strength.
Two common types of modified bitumen are SBS and APP.
SBS Modified Bitumen
Styrene-butadiene-styrene (SBS) modified bitumen uses a rubber-like polymer to improve membrane flexibility.
SBS membranes are designed to accommodate movement and temperature changes. Depending on the product, installation may involve heat, adhesives, or other approved methods.
APP Modified Bitumen
Atactic polypropylene (APP) modified bitumen uses a plastic-based modifier that affects the membrane's heat resistance and flexibility.
Many APP membranes are designed for torch application, although installation requirements depend on the specific product.
Torch-On Roofing Membrane Layers
Some modified bitumen roofing systems use a base sheet and a cap sheet.
The base sheet provides part of the waterproofing assembly, while the cap sheet forms the exposed upper surface. Certain cap sheets have mineral granules that help protect the membrane from sunlight.
The number of layers and installation method depend on the roofing system and project specifications.
All Coast Roofing considers the building's requirements when assessing the appropriate membrane installation.
Torch-On Roofing for Residential and Commercial Properties
Torch-on roofing can be used on several types of buildings, but installation requirements vary depending on the roof's structure and intended use.
Residential Torch-On Roofing
Residential torch-on roofing is commonly used on Vancouver homes with flat roofs, garages, and low-slope additions.
These roofing areas require dependable waterproofing, especially where the membrane meets exterior walls, skylights, or other building components.
All Coast Roofing provides residential torch-on roofing services for homeowners experiencing leaks, aging roofing materials, or drainage concerns.
Our team can assess whether the existing membrane requires repairs or whether a new roofing system would be more appropriate.
Visit our residential roofing Vancouver page for more information.
Commercial Torch-On Roofing
Commercial torch-on roofing is used on some low-slope commercial buildings, including retail properties, offices, and smaller industrial facilities.
Commercial roofs may contain ventilation equipment, drains, service walkways, and other components that require careful membrane detailing.
All Coast Roofing provides commercial roofing inspections, repairs, and replacement services to help property owners address waterproofing problems and maintain their roofing systems.
For commercial properties requiring additional roofing work, explore our commercial roofing services in Vancouver.
Torch-On Roofing for Strata Properties
Strata buildings can have roofing systems that cover multiple residential units, common areas, and shared building components.
When torch-on membranes begin to deteriorate, water infiltration can affect more than one part of the property.
Our team can assist strata councils and property managers with roofing inspections, repairs, and replacement planning.
Learn more about our strata roofing services in Vancouver.
Why Torch-On Roofing Works Well in Vancouver's Climate
Vancouver's wet climate makes roof waterproofing and drainage especially important.
Flat and low-slope roofs are exposed to frequent rainfall, moisture accumulation, and seasonal changes in temperature. When a roof has inadequate drainage or deteriorating membrane seams, water can enter the roofing assembly and potentially damage the building.
A properly installed torch-on roof provides a continuous waterproof barrier designed to protect against rainwater.
However, the membrane is only one part of the system. Effective drainage, suitable flashing, and regular maintenance are also necessary.
Preventing Water Accumulation
Standing water can develop when roof drains become blocked or the roofing surface does not have sufficient slope.
Although some temporary ponding can occur after rainfall, persistent standing water should be investigated.
Depending on the roof's condition, drainage improvements may involve clearing blocked drains, repairing low areas, or considering changes to the roof's slope during replacement.
Protecting Roof Edges and Penetrations
Roof edges, vents, skylights, and drainage openings are common areas where water infiltration can develop.
These locations require properly installed flashing and compatible roofing materials.
All Coast Roofing considers these areas when inspecting existing roofs and planning membrane repairs or replacement.
Maintaining Roof Performance
Regular inspections help identify drainage problems, membrane damage, and deteriorating seams before they lead to more extensive repairs.
Property owners should also monitor the roof after major storms and prolonged periods of heavy rainfall.
Signs Your Torch-On Roof Needs Repair or Replacement
Torch-on roof damage is not always obvious from inside the building. Some problems begin at membrane seams or around rooftop equipment before water becomes visible indoors.
Common warning signs include:
- Cracks, punctures, or splits in the membrane
- Blistering or raised sections of roofing material
- Loose or separating membrane seams
- Damaged flashing around roof penetrations
- Repeated water leaks or interior ceiling stains
- Persistent standing water after rainfall
- Widespread deterioration of the membrane surface
Blistering does not always mean a roof needs immediate replacement. However, it can indicate trapped air or moisture and should be assessed to determine whether repairs are necessary.
If the roof has experienced repeated leaks, a more comprehensive inspection may be required to identify concealed moisture damage.
All Coast Roofing can assess the roof and recommend repair or replacement based on its condition.
Torch-On Roof Repair vs. Replacement
Choosing between torch-on roof repair and replacement depends on the membrane's age, the extent of the damage, and the condition of the materials underneath.
A repair may be appropriate when the damage is limited to a small area and the remaining membrane is in good condition.
Replacement may be necessary when large sections of the membrane have deteriorated or moisture has damaged the roof assembly.
| Roof condition | Possible solution |
|---|---|
| Small puncture or localized crack | Membrane repair |
| Damaged flashing around a vent | Flashing repair or replacement |
| Loose membrane seam | Seam assessment and repair |
| Blocked roof drain | Drain cleaning and inspection |
| Recurring ponding water | Drainage assessment |
| Multiple recurring leaks | Detailed inspection and possible replacement |
| Widespread membrane deterioration | Torch-on roof replacement |
| Moisture-damaged insulation or roof deck | Replacement of affected materials |
A professional assessment is important because the visible damage may not show the full extent of moisture infiltration.

How Much Does Torch-On Roofing Cost in Vancouver?
Torch-on roofing prices in Vancouver depend on the roof's size, accessibility, existing materials, and the scope of the project.
A simple membrane repair will generally cost less than removing and replacing an entire roofing system. However, replacement costs can increase when the existing insulation, roof deck, or drainage components also require work.
Several factors affect torch-on roofing costs in Vancouver.
Roof Size and Layout
Larger roofing areas require more materials and labour. Roofs with numerous penetrations, parapet walls, or complex flashing details may also require additional installation work.
Existing Roof Condition
If the current roofing system contains water-damaged insulation or deteriorated decking, those materials may need to be replaced before a new membrane is installed.
Roofing Materials
The selected modified bitumen system, number of membrane layers, insulation requirements, and flashing materials influence the overall project cost.
Roof Accessibility
Roof height, equipment access, site restrictions, and the need to protect occupied areas can affect labour and project planning.
Drainage Improvements
Some roofs require changes to existing drains or additional slope to improve water movement.
Because every roofing project has different requirements, All Coast Roofing recommends an inspection before providing a detailed estimate.

Our Torch-On Roofing Installation Process
Professional installation helps ensure that modified bitumen membranes are applied correctly and that vulnerable areas receive appropriate waterproofing.
All Coast Roofing follows a project-specific approach based on the roof's construction, existing materials, and installation requirements.
1. Roof Assessment and Preparation
Our team begins by assessing the roofing surface, drainage, flashing, and underlying structure.
Existing materials are reviewed to determine whether repairs, removal, or additional preparation are required.
The installation surface must be suitable for the selected membrane system.
2. Roofing System Preparation
Depending on the project, the roofing system may require a base sheet, insulation, protective layers, or other specified components before membrane installation.
Some roofs also require drainage corrections or localized deck repairs.
3. Torch-On Membrane Installation
When torch application is suitable, trained roofing contractors use controlled heat to bond the modified bitumen membrane in accordance with the system's requirements.
Special attention is given to membrane overlaps, transitions, and flashing details.
Because open-flame roofing carries fire risks, torch application must only be performed under appropriate conditions with necessary precautions. Alternative application methods may be required around combustible materials.
4. Seams and Flashing
Roof edges, penetrations, drains, and other transitions receive detailed waterproofing treatment.
Properly completed seams and flashing help maintain the continuous waterproof barrier.
5. Final Roof Inspection
After installation, the completed roofing areas are inspected for visible defects and installation concerns.
The team also reviews drainage areas and relevant membrane details.
How to Maintain a Torch-On Roof
Regular maintenance can help extend the useful life of a torch-on roofing system and reduce the risk of water infiltration.
Property owners should arrange periodic inspections and address visible membrane damage before it becomes more extensive.
Important maintenance tasks include:
- Keeping roof drains and scuppers clear
- Removing leaves and debris from drainage areas
- Inspecting accessible roof edges and flashing
- Monitoring areas where water repeatedly collects
- Checking for damage around rooftop equipment
- Scheduling professional repairs when leaks or membrane defects appear
Property owners should avoid cutting, puncturing, or attempting to heat roofing membranes themselves. Torch-on roof repairs require appropriate equipment and professional fire-safety procedures.
All Coast Roofing also provides property maintenance services in Vancouver to help protect roofing and exterior building components.
