All Coast Roofing provides professional flat roofing services in Vancouver for residential, commercial, and strata properties. Whether you need flat roof repair, a complete roof replacement, or a new roofing system installed, our team can assess your property's condition and recommend a suitable solution.
Vancouver's frequent rainfall makes proper drainage, waterproofing, and roofing materials especially important. A poorly installed or damaged flat roof can allow water to collect around drains, penetrate roof membranes, and cause moisture damage inside the building.

If you are looking for experienced flat roofing contractors in Vancouver, Burnaby, North Vancouver, or West Vancouver, contact our team for a free estimate.
Flat Roof Experts in Vancouver
Flat roofing requires specialized installation and repair techniques because low-slope roofs handle rainwater differently from pitched roofs. Although a flat roof may appear level, it should have sufficient slope and drainage to direct water towards roof drains, scuppers, or gutters.
Our flat roofing contractors work with property owners to identify leaks, assess roofing materials, and determine whether repairs or replacement are needed.
Common flat roofing problems include damaged membranes, deteriorating flashing, blocked drains, and standing water. These issues can become more serious during Vancouver's rainy season, particularly when water enters beneath the roofing surface.
All Coast Roofing provides flat roofing solutions for:
- Residential homes, garages, and additions
- Commercial buildings and retail properties
- Strata buildings and multi-family properties
- Apartment buildings and townhouses
- Low-slope roofs and rooftop structures
Our approach starts with understanding the condition of the roof before recommending repairs, installation, or replacement.
Why Choose All Coast Roofing for Flat Roofing?
Choosing a flat roofing company involves more than comparing estimates. The contractor should understand low-slope roofing systems, drainage requirements, and the weather conditions that affect buildings throughout Metro Vancouver.

Flat Roofing Services in Vancouver
All Coast Roofing provides flat roofing services for new construction, existing buildings, and properties experiencing roofing problems.
Our services include flat roof installation, repairs, replacement, waterproofing, and maintenance.
Flat Roof Installation Vancouver
Proper flat roof installation is essential for keeping moisture out of the building and allowing rainwater to drain efficiently.
Before beginning a flat roof installation in Vancouver, our team evaluates the roof structure, existing materials, drainage, and project requirements. These factors help determine which roofing system is appropriate for the property.
The installation process may include:
- Inspecting the roof deck and existing structure
- Preparing the roofing surface
- Installing insulation or a slope package where required
- Applying the selected roofing membrane
- Installing flashing around roof edges and penetrations
- Sealing membrane seams and checking drainage details
Different roofing systems require different installation techniques. The appropriate method depends on the membrane, roof structure, and manufacturer's specifications.
Whether you are building a new property or replacing an existing roof, our new roof installation services can help you plan the project.
Flat Roof Repair Vancouver
Flat roof leaks can develop around membrane seams, roof penetrations, drains, and damaged flashing. In some cases, water travels beneath the roofing membrane before becoming visible inside the building.
Our flat roof repair services in Vancouver focus on identifying the source of the problem and determining the appropriate repair.
Common flat roof repairs include:
- Repairing punctures, cracks, and damaged membrane sections
- Addressing leaking seams and flashing
- Repairing areas around vents and skylights
- Investigating standing water and drainage problems
- Replacing damaged roofing components where necessary
- Addressing localized water infiltration
A professional inspection can help determine whether the damage is limited to one area or affects a larger portion of the roofing system.
If you notice water stains, dripping, or damaged roofing materials, contact our team for roof repair in Vancouver, BC.
Flat Roof Replacement Vancouver
Flat roof replacement may be necessary when an existing roofing system has widespread damage, recurring leaks, or significant deterioration.
Although some flat roof problems can be repaired, repeated water infiltration may indicate that the membrane, insulation, or underlying roof deck requires more extensive work.
During a flat roof replacement, our contractors assess the existing system and determine which materials need to be removed or replaced.
A replacement project may involve removing the old membrane, repairing damaged decking, improving drainage, installing insulation, and applying a new waterproof roofing system.
The exact work depends on the roof's condition and the selected materials.
Property owners considering flat roof replacement in Vancouver should also evaluate the condition of roof drains, flashing, and penetrations. Addressing these components during replacement can help prevent future leaks.
For larger properties, explore our commercial building roof replacement services.
Flat Roof Waterproofing
Waterproofing is one of the most important parts of flat roof construction in Vancouver.
Unlike steep roofs, flat roofs rely heavily on continuous waterproof membranes, properly sealed seams, and carefully installed flashing to prevent water infiltration.
Areas requiring particular attention include:
- Roof drains and scuppers
- Parapet walls and roof edges
- Skylights and ventilation openings
- Membrane joints and transitions
- Rooftop equipment penetrations
Waterproofing work should address the cause of the leak rather than simply covering visible damage.
Our team can inspect problem areas and recommend suitable repairs or replacement based on the roofing system.
Types of Flat Roofing Systems
Several roofing materials are used for residential and commercial flat roofs in Vancouver. Each system has different installation requirements, maintenance needs, and performance characteristics.
Choosing the right material depends on the roof's design, drainage, intended use, and existing structure.
Torch-On Roofing and Modified Bitumen
Modified bitumen is a common roofing material for low-slope and flat roofs. It consists of asphalt-based sheets modified with polymers to improve flexibility and performance.
Some modified bitumen systems use heat during installation to bond membrane layers and create watertight seams.
Torch-on roofing is commonly used for residential additions, garages, and commercial roofing applications.
The installation method must be suitable for the building and carried out with appropriate fire-safety precautions.
Learn more about our torch-on roofing services in Vancouver.
TPO Roofing
Thermoplastic polyolefin (TPO) is a single-ply roofing membrane used on many commercial and low-slope roofs.
TPO systems typically use heat-welded seams and are available with reflective surfaces that can help reduce solar heat absorption.
Proper membrane attachment, seam welding, and flashing installation are essential to the system's performance.
EPDM Rubber Roofing
EPDM is a synthetic rubber membrane commonly used for flat and low-slope roofs.
Its flexibility makes it suitable for a range of roofing applications. Installation methods vary and may include mechanically attached, adhered, or ballasted systems, depending on the design.
EPDM roofing requires compatible seam materials and properly detailed penetrations to maintain waterproofing.
PVC Roofing
PVC roofing uses a flexible thermoplastic membrane with heat-welded seams.
It is used on commercial buildings and other low-slope roofing applications. Certain PVC systems may be suitable for roofs exposed to specific chemicals or grease, depending on product specifications.
Built-Up Roofing
Built-up roofing (BUR) consists of multiple layers of reinforcing materials and bitumen.
These systems have been used on commercial flat roofs for decades. The suitability of a built-up roof depends on the building structure, drainage requirements, and installation conditions.
Our flat roofing contractors can help property owners understand which roofing systems may be suitable for their buildings.
Commercial Flat Roofing Vancouver
Commercial flat roofs often cover larger surface areas and may contain rooftop equipment, ventilation systems, and multiple drainage points.
These features require careful planning during installation, maintenance, and repair.
All Coast Roofing provides commercial flat roofing services in Vancouver for business owners, building managers, and commercial property owners.
Our work may include roof inspections, membrane repairs, drainage assessments, and complete roofing replacements.
Commercial property owners should pay particular attention to roof drains and areas surrounding mechanical equipment. Blocked drainage or deteriorating flashing can allow water to collect and increase the risk of leaks.
When repairs are needed, we assess the affected areas and recommend a practical approach based on the roof's condition.
Visit our commercial roofing Vancouver page to learn more about roofing services for commercial properties.
Residential Flat Roofing in Vancouver
Flat roofs are used on many Vancouver homes, particularly modern houses, garages, extensions, and rooftop decks.
Residential flat roofing systems require reliable waterproofing and effective drainage to protect the living spaces below.
Some homes have a combination of pitched and flat roofing sections. These transitions require properly installed flashing to prevent water from entering where different roofing systems meet.
Our residential flat roofing services can address leaking membranes, drainage problems, aging materials, and roof replacement needs.
For homeowners planning renovations or dealing with roofing damage, our team can evaluate the existing roof and discuss suitable repair or installation options.

Signs Your Flat Roof Needs Repair or Replacement
Flat roofing problems may develop gradually, especially when water remains on the roof after rainfall.
Some warning signs are visible from inside the building, while others require a professional roof inspection.
Standing Water on the Roof
Ponding water occurs when rainwater collects in low areas instead of draining efficiently.
Water that remains for extended periods can indicate blocked drains, insufficient slope, or changes in the roof structure.
Not all temporary standing water means the roof has failed, but recurring ponding should be investigated.
Water Stains and Interior Leaks
Water stains on ceilings or walls may indicate moisture entering through the roof.
Leaks can develop around flashing, roof penetrations, membrane seams, or damaged roofing sections.
Because water can travel beneath roofing materials, the visible stain may not identify the exact entry point.
Cracked or Damaged Roofing Membranes
Cracks, punctures, open seams, and surface deterioration can compromise a flat roof's waterproofing.
These problems may develop through aging, weather exposure, or damage from rooftop equipment and foot traffic.
Damaged Flashing
Flashing protects vulnerable areas where the roofing membrane meets walls, edges, and penetrations.
Loose or deteriorating flashing can allow rainwater to enter beneath the roofing system.
Repeated Roof Repairs
If the same flat roof continues leaking after several repairs, a more comprehensive inspection may be necessary.
Repeated leaks can indicate wider membrane deterioration, drainage problems, or moisture trapped within the roofing assembly.
Our team can help determine whether additional repairs or flat roof replacement would be the more practical option.
Why Vancouver Flat Roofs Need Proper Drainage
Vancouver receives substantial rainfall throughout the year, making roof drainage especially important.
Although flat roofs appear level, they should be designed to direct water towards designated drainage points.
When drains become blocked by leaves, moss, or debris, water may collect around roof penetrations and low areas.
Over time, persistent ponding can place additional stress on roofing materials and contribute to moisture problems.
Proper flat roof drainage may involve:
- Maintaining clear roof drains and scuppers
- Checking for debris around drainage outlets
- Assessing low areas where water regularly collects
- Inspecting flashing around drainage components
- Evaluating whether additional slope improvements are needed
Some roofing projects may benefit from a tapered insulation system or slope package to improve water movement.
If your property experiences frequent drainage problems, our contractors can inspect the roof and recommend appropriate maintenance or repairs.
Flat Roof Maintenance Services
Routine maintenance helps property owners identify roofing problems before they develop into more extensive damage.
Flat roof maintenance is especially important for buildings exposed to Vancouver's frequent rainfall and seasonal debris.
Regular inspections can help identify blocked drains, damaged flashing, membrane deterioration, and other conditions that may affect the roof.
A flat roof maintenance visit may include:
- Inspecting the roof membrane for visible damage
- Checking seams and flashing
- Removing debris from drainage areas
- Examining roof penetrations
- Identifying ponding water and drainage concerns
- Recommending necessary repairs
Commercial property managers may also benefit from documenting roof conditions and previous repairs to support future maintenance planning.
All Coast Roofing provides property maintenance services in Vancouver to help protect roofing systems and exterior building components.
Flat Roof Repair vs. Replacement: Which Is Better?
Choosing between flat roof repair and replacement depends on the age of the roofing system, the extent of the damage, and the condition of the underlying materials.
Repairs may be suitable when the roof is generally in good condition and the damage is limited to a specific area.
Replacement may be more appropriate when the membrane has widespread deterioration, leaks occur repeatedly, or moisture has damaged the underlying insulation and roof deck.
A professional inspection helps determine which option is appropriate.
| Roof condition | Possible solution |
|---|---|
| Small membrane puncture | Localized repair |
| Damaged flashing around a vent | Flashing repair or replacement |
| Blocked roof drain | Drain cleaning and inspection |
| Recurring ponding water | Drainage assessment and possible slope improvements |
| Multiple leaks across the roof | Comprehensive inspection and possible replacement |
| Widespread membrane deterioration | Flat roof replacement |
| Moisture-damaged insulation or decking | Removal and replacement of affected materials |
The final recommendation should be based on the roof's actual condition rather than its age alone.
Our Flat Roofing Installation and Repair Process
At All Coast Roofing, we aim to make flat roofing projects straightforward for homeowners and commercial property owners.
Step 1: Roof Inspection
We begin by reviewing the reported roofing problem and inspecting accessible areas of the roof.
Our team looks for visible membrane damage, drainage concerns, deteriorating flashing, and other potential sources of water infiltration.
Step 2: Roofing Recommendations
After assessing the roof, we explain the findings and discuss appropriate repair or replacement options.
Recommendations depend on the existing roofing system, the extent of the damage, and the property's requirements.
Step 3: Project Estimate
We provide an estimate outlining the proposed roofing work.
For larger replacement projects, additional considerations may include roof access, material selection, drainage modifications, and the condition of the underlying structure.
Step 4: Roofing Work
Our contractors complete the agreed roofing work using installation methods appropriate for the selected system.
We pay attention to membrane details, flashing, and drainage because these components are essential to flat roof performance.
Step 5: Final Review
After completing the work, we review the finished roofing areas and discuss relevant maintenance considerations with the property owner.

Frequently Asked Questions About Flat Roofing
How long does a flat roof last in Vancouver?
A properly installed flat roof may last approximately 20 to 30 years, depending on the roofing material, installation quality, drainage, and maintenance. Some systems have shorter or longer expected service lives. Vancouver's wet climate makes regular inspections particularly important.
How much does flat roof replacement cost in Vancouver?
Flat roof replacement costs in Vancouver depend on the roof's size, existing materials, accessibility, insulation, drainage, and the condition of the roof deck. A professional inspection is the best way to determine the required work and obtain an accurate estimate.
Can a leaking flat roof be repaired?
Yes, many leaking flat roofs can be repaired when the damage is localized and the remaining roofing system is in good condition. However, extensive membrane deterioration or moisture damage may require partial or complete replacement.
What is the best roofing material for a flat roof in Vancouver?
Modified bitumen, TPO, EPDM, PVC, and built-up roofing are among the materials used for flat roofs. The best option depends on the building's structure, roof design, drainage, intended use, and project requirements.
How often should a flat roof be inspected?
Flat roofs should generally be inspected at least once or twice a year and after significant storms. Commercial roofs and buildings with drainage concerns may require more frequent inspections.
Is standing water normal on a flat roof?
Some temporary standing water can occur after heavy rainfall, but water that remains for extended periods may indicate a drainage problem. Persistent ponding should be assessed to determine whether drain cleaning, repairs, or slope improvements are necessary.

What Clients Say
-
Today, Dec 30th, our roof decided to spring a major leak, causing damage inside the house. A roofer was desperately needed to tarp our roof. I found All Coast Roofing online, which was very close to me. Alex, the owner of the company, contacted his crew to see if they could fit this project into their schedule today. Unfortunately that wasn’t a possibility, but sensing the worry in my voice he came by himself to tarp our roof. He also added a few shingles to patch the main area causing the leak. From placing the phone call to the end of the job, less than 2 hours passed by! I can not express my gratitude enough to Alex for coming by immediately, doing the job and easing my worry. You can tell a lot about a company by how the owner conducts business. I have no hesitation in recommending this company for your roofing needs. Quick, efficient, knowledgeable, safe and will go above and beyond to satisfy you. All Coast Roofing…Alex…thank you and Happy New Year!
