How Much Does It Cost to Replace a Cedar Shake Roof in BC?
How Much Does It Cost to Replace a Cedar Shake Roof in BC? For many homeowners in British Columbia's Lower Mainland, replacing an aging cedar roof can cost approximately $20,000 to $60,000 or more, depending on the roof's size, condition, complexity, and the replacement material selected.
A cedar roof replacement involves more than installing new shingles or panels. Older cedar roofing systems may require complete removal, new plywood decking, updated waterproofing, and repairs to deteriorated wood before the new roof can be installed.
Homeowners in Vancouver, Surrey, Langley, Abbotsford, Chilliwack, and surrounding communities also need to consider how British Columbia's wet climate affects their roofing choices.
Whether you're considering new cedar shakes, asphalt shingles, or a long-lasting metal roofing system, understanding the costs and available options will help you make a more informed investment in your home.
How Much Does It Cost to Replace a Cedar Shake Roof in BC?
For a residential home with approximately 2,000 square feet of actual roof surface, the following figures provide general 2026 budgeting estimates for a complete cedar shake roof replacement.
Replacement roofing material | Estimated project cost |
Architectural asphalt shingles | $20,000–$35,000 |
Architectural metal shingles | $30,000–$55,000+ |
Standing seam metal roofing | $30,000–$55,000+ |
New cedar shakes | $30,000–$55,000+ |
Important: These are illustrative planning ranges in Canadian dollars, not confirmed Valley Metal Roofing prices or guaranteed local market averages. They assume removal and disposal of the existing cedar roofing and typical roof preparation.
Extensive plywood replacement, structural repairs, complex roof geometry, access requirements, and other project-specific work may increase the total. GST is additional.
The cost of replacing your cedar roof depends on several factors:
Total roof surface area.
Existing roof decking and structural condition.
Roof pitch and architectural complexity.
Accessibility and equipment requirements.
Roofing material and installation system.
Waterproofing, flashing, and ventilation requirements.
Labour, disposal, and any necessary repairs.
The most reliable way to determine your roof replacement cost is through a professional inspection and a detailed proposal based on your home's actual condition.
How Much Does It Cost to Replace a Cedar Shake Roof in BC? Cost Per Square Foot Explained
Roofing contractors generally calculate roof replacement pricing based on the actual roof surface area, not the interior square footage of the home.
For example, a 2,000-square-foot two-storey home may have considerably less roof surface area than a 2,000-square-foot rancher.
The total roof area depends on factors such as roof pitch, overhangs, valleys, dormers, and the building's overall design.
Contractors may also measure roofing in squares, with one roofing square equal to 100 square feet of roof surface.
A roof with 2,000 square feet of actual surface area is equivalent to 20 roofing squares.
However, square-foot pricing alone cannot account for every aspect of a cedar roof replacement.
Two homes with identical roof areas may have significantly different replacement costs if one requires extensive decking repairs, specialized flashing, or additional installation labour.
Why Does Replacing a Cedar Shake Roof Cost More Than a Typical Roof Replacement?
Cedar shake roof replacements often require additional preparation compared with replacing conventional asphalt shingles.
Many older cedar roofing systems were installed using construction methods that differ from the requirements of modern asphalt and metal roofing systems.
The following components can substantially influence the final cost.
1. Removing and Disposing of the Existing Cedar Shakes
A complete cedar roof replacement typically begins with removing the existing roofing material.
This may include removing:
Cedar shakes and ridge components.
Existing fasteners.
Deteriorated underlayment.
Damaged flashing.
Other materials that cannot be incorporated into the replacement system.
Removing the existing roofing also allows the contractor to inspect the underlying structure for hidden problems.
Older cedar roofs can conceal moisture damage or deteriorated wood that is not visible during an exterior inspection.
Proper disposal and site cleanup should also be included in the replacement scope.
2. Installing New Plywood Roof Decking
One of the most important considerations when replacing cedar shakes is the condition and type of existing roof decking.
Many older cedar roofs were installed over skip sheathing.
Skip sheathing is a roof deck constructed with spaced wooden boards rather than a continuous plywood surface.
This type of construction was commonly used beneath traditional wood shakes.
However, many modern roofing systems require continuous, properly supported roof decking.
When replacing cedar with asphalt shingles or certain metal roofing systems, new plywood may be required to provide a suitable installation surface.
The appropriate decking solution depends on the existing structure, the roofing manufacturer's installation requirements, and applicable building regulations.
This additional preparation can represent a significant portion of the replacement cost.
3. Repairing Damaged or Deteriorated Wood
British Columbia's wet climate makes moisture management an important consideration in residential roofing.
Over time, water entering through damaged cedar shakes, deteriorated flashing, or poorly detailed roof penetrations can affect the underlying roof structure.
During replacement, contractors may discover:
Rotten roof boards or plywood.
Damaged fascia.
Deteriorated framing.
Moisture damage around skylights.
Problems around chimneys and roof-to-wall transitions.
Some issues can be identified during an initial inspection, while others may only become visible after the existing roofing is removed.
A professional roofing proposal should explain how unforeseen repairs will be assessed, approved, and priced.
4. Roof Pitch, Height, and Architectural Complexity
A simple roof with minimal penetrations is generally more straightforward to replace than a steep roof with multiple valleys, dormers, skylights, and intersecting sections.
Complex roof designs may require additional labour, specialized flashing, safety equipment, and installation time.
Access can also influence pricing.
For example, homes on steep or restricted properties in North Vancouver or West
Vancouver may require different material-handling arrangements than homes with open driveway access in parts of the Fraser Valley.
What Affects Cedar Roof Replacement Costs in Vancouver and the Fraser Valley?
Although the same roofing materials may be used throughout the Lower Mainland, individual properties can have very different installation requirements.
Several regional considerations are worth understanding.
Heavy Rainfall and Moisture Exposure
The Lower Mainland experiences extended periods of wet weather, particularly during fall and winter.
Roofing systems must be designed and installed to manage rainwater effectively, with appropriate attention to underlayment, flashing, roof penetrations, and ventilation.
Older Homes and Existing Roof Construction
Some older homes throughout Vancouver, Burnaby, Surrey, and the Fraser Valley have cedar roofing installed over spaced sheathing.
Depending on the replacement material, these homes may require additional decking preparation.
Tree Coverage and Shaded Roof Areas
Properties surrounded by mature trees can experience prolonged shade, falling debris, and increased moisture retention.
These conditions may encourage moss growth and can affect roofing maintenance requirements.
Property Access and Roof Design
Hillside properties, narrow driveways, limited staging areas, and steep roof slopes can affect how roofing materials are delivered, handled, and installed.
For these reasons, a roof replacement estimate based only on your home's square footage may not accurately reflect the work required.
Should You Replace Cedar Shakes With Cedar, Asphalt, or Metal Roofing?
When an existing cedar shake roof reaches the end of its useful life, homeowners have several replacement options.
Each material offers different benefits, maintenance requirements, and long-term costs.
Replacing Cedar With New Cedar Shakes
Cedar shakes are known for their natural appearance and traditional West Coast character.
They can complement heritage-style homes, timber architecture, and properties where natural materials are an important design consideration.
Advantages of cedar roofing:
Natural wood appearance.
Traditional architectural character.
Potential for decades of service when properly installed and maintained.
Considerations:
Requires ongoing inspections and maintenance.
Susceptible to moisture-related deterioration.
Moss growth can be a concern in shaded areas.
Appearance changes naturally as the wood weathers.
Performance depends on product quality, installation, ventilation, and environmental exposure.
For homeowners who want the appearance of cedar without using natural wood as their primary roofing material, architectural metal shingles may offer an alternative.
Replacing Cedar With Asphalt Shingles
Asphalt shingles are a common replacement option because they generally have a lower upfront cost than premium metal roofing.
Advantages of asphalt roofing:
Comparatively affordable initial installation.
Wide range of colours and profiles.
Familiar installation and repair methods.
Suitable for many residential roof designs.
Considerations:
Typically shorter expected service life than quality metal roofing.
Can experience granule loss, curling, and age-related deterioration.
May require moss management and periodic maintenance.
Future replacement costs should be considered.
Asphalt roofing can be a practical option for homeowners prioritizing the initial installation budget.
However, the lowest upfront cost does not always result in the lowest long-term ownership cost.
Replacing Cedar With Metal Roofing
Metal roofing has become an attractive option for homeowners seeking long-term durability, architectural appeal, and reduced maintenance compared with natural cedar.
Modern metal roofing is available in a variety of styles, including systems designed to resemble traditional cedar shakes and slate.
At Valley Metal Roofing, we specialize in premium metal roofing systems, including:
Ironwood Shake
An architectural metal roofing system designed to recreate the appearance of traditional wood shakes while offering the characteristics of coated steel roofing.
Ironstone Slate
A metal roofing system designed to provide the appearance of slate, offering homeowners an alternative to conventional roofing materials.
Standing Seam Metal Roofing
A premium metal roofing system featuring continuous panels and concealed fastening, providing a clean architectural appearance.
Depending on the selected product and installation system, metal roofing can offer:
Long expected service life.
Reduced maintenance compared with natural cedar.
Durable factory-applied finishes.
Resistance to many forms of weather-related deterioration.
A range of architectural profiles and colours.
Concealed fastening options.
Although premium metal roofing generally requires a higher initial investment than asphalt shingles, its long-term durability may make it attractive to homeowners planning to remain in their properties for many years.
Real Project Example: Replacing Cedar Roofing With Ironstone Slate in Abbotsford
A practical way to understand what is involved in replacing a cedar roof is to look at an actual project.
Valley Metal Roofing completed a residential roofing project in Abbotsford, British Columbia, where the existing cedar roofing was removed and replaced with Ironstone Slate in Charcoal Grey.
The project involved several important stages.
Removing the Existing Cedar Roof
The original cedar roofing was removed to prepare the home for the replacement system.
Removing the existing material provided access to the underlying roof structure and allowed the installation team to prepare the roof for the new assembly.
Installing New Plywood
New plywood was installed to create an appropriate roof deck for the selected roofing system.
This was an important part of preparing the home for its new metal roof.
Installing the Waterproofing Barrier
Before installing the metal roofing, a waterproofing barrier was applied as part of the new roofing assembly.
Proper waterproofing and detailing are essential components of a reliable roofing system, particularly in British Columbia's wet climate.
Installing Ironstone Slate in Charcoal Grey
The project was completed with Ironstone Slate metal roofing in Charcoal Grey.
The finished roof provides a slate-inspired architectural appearance while replacing the original cedar roofing with a metal roofing system.
This project demonstrates why replacing cedar involves more than changing the visible roofing material.
Removal, decking preparation, waterproofing, and installation workmanship all contribute to the completed roofing system.
For homeowners considering a similar transformation, a professional inspection can help determine what preparation their existing roof will require.
How Long Does a Cedar Shake Roof Last in British Columbia?
A properly installed cedar shake roof may provide approximately 20 to 40 years of service, depending on the cedar quality, exposure, maintenance, ventilation, and installation.
Some cedar roofs perform well beyond this range, while others deteriorate earlier.
The Lower Mainland's climate can influence how cedar roofing ages.
Extended rainfall, shade, organic debris, and moisture retention may contribute to deterioration, particularly where ventilation or drainage is inadequate.
Routine maintenance can help identify issues early, but it cannot reverse extensive wood decay.
How Long Does Metal Roofing Last Compared With Cedar?
A quality metal roofing system may provide approximately 40 to 60 years or more of service, depending on the material, coating, installation, environment, and maintenance.
However, no roofing material has a guaranteed lifespan simply because of its product category.
The longevity of any roof depends on the complete roofing assembly and the quality of its installation.
Roofing material | General potential service life |
Architectural asphalt shingles | Approximately 15–30 years |
Cedar shakes | Approximately 20–40 years |
Quality metal roofing | Approximately 40–60+ years |
These are broad planning ranges, not guaranteed service lives. Actual performance can vary substantially.
For homeowners evaluating a major roof replacement, expected service life should be considered alongside installation cost, maintenance, appearance, and warranty coverage.
Is Metal Roofing Worth the Higher Initial Cost?
For homeowners focused on long-term value, metal roofing may be worth the additional upfront investment.
The important consideration is the lifetime cost of ownership.
Lifetime cost of ownership refers to the total cost of purchasing, maintaining, repairing, and eventually replacing a roofing system over a defined period.
For example, a homeowner comparing roofing systems over 50 years should consider:
The initial roof replacement cost.
Routine maintenance expenses.
Potential repair costs.
Future roof replacement costs.
The expected service life of each system.
An asphalt roof may have a lower initial cost but could require replacement again within the same period that a quality metal roof remains serviceable.
However, metal roofing is not automatically the least expensive choice over every timeframe. The result depends on actual installation costs, achieved service life, maintenance, and future prices.

Can You Install Metal Roofing Directly Over Existing Cedar Shakes?
Removing the existing cedar shakes is generally the recommended approach when replacing an aging cedar roof with metal roofing.
Cedar shakes are relatively thick and uneven, and older installations may conceal deterioration in the underlying roof structure.
Installing new roofing directly over existing cedar can make it difficult to inspect the deck and meet the installation requirements of the replacement system.
Removing the cedar allows the contractor to:
Inspect the underlying roof structure.
Identify concealed moisture damage.
Replace damaged wood where necessary.
Install appropriate decking and underlayment.
Prepare the roof for the selected metal roofing system.
The exact requirements depend on the existing roof construction, manufacturer specifications, and applicable building regulations.
Homeowners with existing asphalt roofing may have different installation options.

What Are the Signs That Your Cedar Shake Roof Needs Replacement?
Not every aging cedar roof requires immediate replacement.
Some roofs can remain serviceable with appropriate repairs and maintenance.
However, several conditions may indicate that a complete replacement should be considered.
1. Cracked, Split, or Missing Cedar Shakes
Minor weathering is normal as cedar ages.
However, widespread cracking, splitting, or missing shakes may compromise the roof's ability to shed water.
2. Rotten or Deteriorating Cedar
Cedar that has become soft, severely deteriorated, or structurally weakened may no longer provide reliable protection.
When deterioration is widespread, replacement may be more practical than repeated repairs.
3. Excessive Moss Growth
Moss is common on roofs throughout British Columbia's Lower Mainland.
Although moss does not automatically mean a roof requires replacement, heavy growth can retain moisture and make underlying deterioration more difficult to assess.
Professional cleaning or treatment may be appropriate when the existing roofing remains in serviceable condition.
4. Recurring Roof Leaks
An isolated leak may be repairable.
However, repeated leaks in multiple locations can indicate broader issues with the roofing material, flashing, or underlying structure.
5. Moisture Problems in the Attic
Water staining, damp insulation, mould-like growth, or deteriorated wood in the attic may indicate a moisture problem.
Importantly, not all attic moisture issues are caused by roof leaks.
Condensation and inadequate ventilation can create similar symptoms, making proper inspection important.

Does Metal Roofing Offer Better Fire Resistance Than Cedar?
Fire performance is another consideration when selecting a replacement roofing material.
Untreated wood shakes can present greater fire vulnerability than many appropriately rated roofing systems.
Metal roofing materials are non-combustible, but the fire classification of a completed roof depends on the tested assembly, including its underlying components.
Homeowners should confirm the applicable fire classification for the specific system being considered.
For properties near forested areas or locations with elevated wildfire exposure, roofing material selection can form part of a broader FireSmart strategy.
However, a fire-resistant roof does not eliminate the importance of maintaining gutters, removing combustible debris, and addressing other wildfire risks around the property.
What Should Be Included in a Cedar Shake Roof Replacement Quote?
A professional roofing proposal should clearly explain the scope of work, materials, installation requirements, and potential additional costs.
Before choosing a contractor, homeowners should review the following:
Quote component | What to confirm |
Cedar removal | Is complete tear-off and disposal included? |
Roof decking | Is new plywood included, if required? |
Wood repairs | How are unforeseen repairs priced and approved? |
Underlayment | What waterproofing materials will be installed? |
Flashing | Are valleys, chimneys, walls, and skylights addressed? |
Ventilation | Will the existing attic ventilation be assessed? |
Roofing material | What product, finish, and profile are specified? |
Workmanship | What installation methods and workmanship warranty apply? |
Material warranty | What coverage, exclusions, and transfer conditions apply? |
Payment schedule | When are deposits and progress payments due? |
Comparing roofing proposals solely by their final price can be misleading.
Two contractors may provide significantly different prices because they are quoting different materials, preparation work, installation methods, or warranty coverage.
A complete roofing proposal should make it clear what you are paying for and what work will be performed.
Why Is a Roof and Attic Inspection Important Before Replacing Cedar?
A cedar shake roof may have underlying problems that are not visible from the ground.
A roof inspection helps assess the condition of the existing roofing, flashing, penetrations, and other exterior components.
An attic inspection can provide additional information about ventilation, moisture, and the visible condition of the roof structure.
At Valley Metal Roofing, our in-home consultation process includes roof and attic inspections to help us better understand the property's condition and discuss suitable replacement options.
This is especially important when replacing older cedar roofing, where decking requirements and concealed deterioration may affect the project scope.
A professional assessment helps homeowners make decisions based on their actual roof rather than relying solely on generic online estimates.
Frequently Asked Questions About Cedar Shake Roof Replacement in BC
How much does it cost to replace a cedar shake roof in Vancouver?
For a home with approximately 2,000 square feet of actual roof area, a complete cedar roof replacement may cost roughly $20,000 to $60,000 or more, depending on the replacement material, roof preparation, access, and structural condition.
These are illustrative budgeting estimates rather than verified contractor quotes. A site-specific inspection is necessary for accurate pricing.
Is it cheaper to replace cedar shakes with asphalt shingles?
Generally, asphalt shingles have a lower upfront installation cost than premium metal roofing or new cedar shakes. However, removing the existing cedar and preparing the roof deck can add significant costs regardless of the replacement material.
