Roof Replacement in Maple Ridge
Paragon Roofing BC replaces roofs across every part of Maple Ridge, from the heritage Hammond townsite to rural Whonnock acreages and the newer Albion and Silver Valley expansion. This page explains how to decide between repair and replacement, what a full tear-off replacement actually includes, which materials suit different Maple Ridge home types, and what the work typically costs and takes. It supports our broader Maple Ridge roofing coverage with replacement-specific depth, backed by completed local projects you can review on this site.
What does a roof replacement in Maple Ridge include?
A full roof replacement in Maple Ridge removes the existing roofing down to the deck and rebuilds the roof as a complete system, not just a new surface.
The scope covers tear-off of the old roofing, inspection of the exposed deck and sheathing, documented approval of any discovered repairs, installation of eave protection membrane and underlayment, new flashing at chimneys, skylights, walls and valleys, correction of intake and exhaust ventilation where needed, and installation of the new roofing system. Each layer protects the one above it, which is why experienced crews treat the roof as an assembly rather than a surface.
For a standard established single family home in Maple Ridge, architectural asphalt replacement typically runs $11,000 to $24,000 and completes in 2 to 4 days. Larger homes, premium materials and complex geometry extend both figures, and the cost table further down this page breaks out the full range by property type. Paragon Roofing BC provides this as part of its regional roof replacement service, with free on-site estimates and detailed written quotes, and residential replacements carry a 20 year workmanship warranty.
How to know your Maple Ridge roof needs replacement rather than repair
Replacement is the right call when the roofing system is failing as a whole. Repair is the right call when the system is sound and a specific component has failed.
A single leak does not automatically mean a roof is finished. Leaks at a chimney, skylight or wall junction are often flashing failures that can be repaired without touching the rest of the roof. The same goes for a small number of wind-lifted or damaged shingles on an otherwise healthy field.
Replacement becomes the better investment when failure indicators appear across the whole roof rather than at one detail. On asphalt roofs, that means widespread granule loss, curling or cracking shingles, and exposed matting on multiple slopes. On cedar roofs, it means splitting, cupping and rot spread through the field rather than confined to one area. Repeated leaks in different locations over a short period are another strong signal, because they suggest the water barrier is failing generally rather than at one point.
Deck condition matters too. If the roof feels soft or spongy underfoot, or sagging is visible from the ground or the attic, moisture has likely reached the sheathing. Patching over a compromised deck wastes money, because the structural layer the new roofing fastens to is itself deteriorating.
Age relative to the material's expected service life is the final consideration. An asphalt roof near the end of its published 25 to 30 year range with visible wear rarely justifies a major repair, because the remaining field will continue to fail around the fix. A professional assessment can confirm which side of the line your roof sits on, and a written report should explain the reasoning rather than just a conclusion.
- Isolated flashing or penetration leak: usually repairable
- Few damaged or lifted shingles on a healthy field: usually repairable
- Widespread granule loss, curling or cracking across slopes: replacement indicator
- Repeated leaks in different locations: replacement indicator
- Soft, spongy or sagging deck areas: replacement indicator
- Cedar with field-wide splitting, cupping or rot: replacement or conversion assessment
Repair or replace: common symptoms and what they usually mean
| What you are seeing | Likely direction | Why |
|---|---|---|
| Leak at one chimney, skylight or wall junction | Repair | Flashing details fail locally and can be rebuilt without replacing a sound field |
| A few lifted, cracked or missing shingles | Repair | Localized wind or impact damage on an otherwise healthy roof is a component failure, not a system failure |
| Granule loss, curling or cracking across multiple slopes | Replacement | Field-wide wear means the water-shedding surface is failing generally and patches will not keep up |
| Leaks appearing in different places over months | Replacement | Scattered leaks indicate the system as a whole is no longer keeping water out |
| Soft or spongy areas underfoot, visible sag | Replacement | Moisture has likely reached the sheathing, and new roofing needs a sound deck to fasten to |
| Cedar roof with widespread splitting, moss and rot | Replacement or cedar conversion | Field-wide cedar deterioration is usually past the point where repairs extend useful life |
How a Maple Ridge roof replacement proceeds, step by step
-
On-site assessment and written quote
A Paragon estimator inspects the roof, attic access where available, flashing details, ventilation and drainage, then provides a free detailed written quote covering materials, scope, the sheathing allowance and warranty terms.
-
Material and scope confirmation
You confirm the roofing system, colour and any upgrades such as ventilation correction or skylight work. Home type matters here: heritage character homes, WUI exposure properties and cedar conversions each push the selection differently.
-
Site protection and tear-off
Landscaping, siding and driveways are protected before the old roofing is stripped to the deck. Full tear-off, rather than overlaying new shingles over old, is the approach suited to the wet South Coast climate because it exposes the deck for inspection and lets every layer be renewed.
-
Deck and sheathing assessment
With the deck exposed, the crew checks for rot, delamination and inadequate fastening. Any sheathing that needs replacement is documented and approved against the per-sheet allowance in your quote before work continues.
-
Eave protection and underlayment
Self-adhering eave protection membrane goes on at the eaves and vulnerable transitions, followed by underlayment across the field. These layers form the secondary water barrier beneath the visible roofing.
-
Flashing and ventilation renewal
Flashing at chimneys, skylights, walls and valleys is replaced rather than reused, since old flashing is a leading leak source on otherwise new roofs. Intake and exhaust ventilation is corrected at the same time, which protects the attic and supports manufacturer shingle warranty conditions.
-
Installation, cleanup and final review
The new roofing system is installed to manufacturer requirements by Paragon crews, the site is cleaned with magnetic sweeps for fasteners, and the completed work is reviewed against the quoted scope.
What happens if rotten sheathing is discovered mid-project
No contractor can fully verify deck condition before tear-off, because the sheathing sits hidden under the roofing. What a good quote can do is remove the uncertainty about cost and process in advance. Paragon quotes include a sheathing replacement allowance with per-sheet pricing stated up front, so if rot or delamination is found once the deck is exposed, the affected sheets are documented, you approve the repair against the published rate, and the project continues without surprise extras.
When comparing quotes from any contractor, ask how discovered deck repairs are priced and approved. A quote that is silent on this is the most common source of mid-project cost disputes.
- Per-sheet sheathing pricing stated in the written quote before work starts
- Discovered damage documented, typically with photos, before repair
- Homeowner approval against the published rate, not an open-ended charge
Replacement considerations by Maple Ridge home type
Maple Ridge housing spans more than a century of construction across a very large municipality, and the right replacement approach differs by cohort. These are the patterns we see across the city.
Post-war homes in West and East Central Maple Ridge and Hammond
Homes from the 1950s through 1980s in the central residential blocks are largely on their second replacement cycle. These projects often benefit most from ventilation correction and full flashing renewal, since original details may predate current practice. Straightforward geometry keeps most of these in the standard cost and timeline range.
- Common systems: architectural asphalt, with metal as an upgrade path
1990s to 2010s expansion in Albion, Cottonwood and Silver Valley
The newer expansion neighbourhoods are reaching or in their first replacement cycle. First-cycle replacement is the natural moment to fix any original ventilation shortfalls and to decide whether to stay with asphalt or step up to a longer-life system, since the premium is paid once against decades of service.
- Common systems: architectural asphalt, standing seam metal, synthetic options on premium builds
Heritage character homes in Hammond and East Central Maple Ridge
Character homes call for material selection that respects the home's appearance. Premium architectural asphalt in darker palettes, synthetic slate and synthetic cedar are common character-compatible choices. On protected properties, scope or material changes may involve City of Maple Ridge heritage planning coordination, which can extend project timelines.
- Common systems: premium architectural asphalt, synthetic slate, Enviroshake
WUI exposure properties in Silver Valley, Whonnock, Ruskin and Yennadon
The forested hillside and rural pockets carry wildland urban interface fire exposure from Golden Ears Provincial Park and surrounding forest. Class A fire rated roofing is increasingly the standard on these properties, and insurance carriers may require Class A materials on rural acreage and park boundary homes. Replacement is the practical moment to make that upgrade.
- Class A options: standing seam metal, synthetic slate, fire retardant Enviroshake, Class A asphalt
Aging cedar roofs anywhere in Maple Ridge
Cedar roofs at the end of their life are usually converted to a modern system rather than re-roofed in cedar. Conversion involves stripping the cedar, preparing or correcting the substrate so it can accept the new system, then installing asphalt, synthetic or metal roofing. The deck preparation stage is what distinguishes a conversion from a standard replacement.
- Conversion targets: architectural asphalt, Enviroshake, synthetic slate, standing seam metal
Comparing replacement materials for Maple Ridge homes
These are the systems Paragon installs most often on Maple Ridge replacements, with lifespan and cost ranges drawn from our published Maple Ridge pricing. The right choice depends on your home type, how long you plan to own it, and any fire exposure or character considerations.
Architectural asphalt shingles
Strengths
- Lowest entry cost of the full replacement options, typically $11,000 to $24,000 on a standard established single family home
- 25 to 30 year published service range
- Wide colour and profile selection suits most Maple Ridge housing cohorts
- Class A fire rated products available for WUI exposure properties
Limitations
- Shortest service life of the options listed here
- Will reach replacement again within a typical long-term ownership horizon
Best for: Most single family replacements where budget and proven performance matter more than maximum lifespan.
Standing seam metal
Strengths
- 50 to 70 year published service range
- Concealed fasteners and continuous panels suit heavy rainfall exposure
- Class A fire rating relevant to Silver Valley, Whonnock, Ruskin and Yennadon properties
Limitations
- Higher cost, typically $22,000 to $66,000 depending on home size and complexity
- Longer installation window than asphalt, typically 6 to 16 days
Best for: Owners planning to stay long term, WUI exposure properties, and homes where a buy-once roof justifies the premium.
Synthetic slate
Strengths
- 50+ year published service range
- Slate appearance suited to heritage and character homes without the structural weight of natural slate
- Class A fire rated options available
Limitations
- Premium cost, typically $30,000 to $80,000
- Appearance-driven choice that not every home style calls for
Best for: Heritage character homes in Hammond and East Central Maple Ridge, and premium builds wanting a distinctive long-life roof.
Synthetic cedar (Enviroshake)
Strengths
- Cedar appearance with a 50+ year published service range and far lower maintenance than natural cedar
- Fire retardant options suit WUI exposure neighbourhoods
- Natural fit for cedar conversions where the owner wants to keep the look
Limitations
- Premium cost, typically $30,000 to $68,000
- Heavier investment than converting to asphalt
Best for: Cedar conversions and character homes where keeping the shake aesthetic matters.
Cedar conversion to asphalt
Strengths
- Most economical exit from a failing cedar roof, typically $18,000 to $40,000 including conversion scope
- Ends the recurring maintenance burden of natural cedar in a wet climate
- 25 to 30 year published service range on the new asphalt system
Limitations
- Changes the home's appearance from shake to shingle
- Conversion adds deck preparation work and typically 2 to 4 days versus a standard replacement
Best for: Owners of aging cedar roofs who want a practical, lower-maintenance modern system.
Maple Ridge roof replacement cost by property type
| Property type and material | Expected lifespan | Typical Maple Ridge cost |
|---|---|---|
| Standard established single family, asphalt | 25 to 30 years | $11,000 to $24,000 |
| Standard newer single family, asphalt | 25 to 30 years | $13,000 to $26,000 |
| Heritage character home, asphalt | 25 to 30 years | $14,000 to $30,000 |
| Custom rebuild, asphalt | 30+ years | $20,000 to $52,000 |
| Larger custom and estate home, asphalt | 30+ years | $28,000 to $80,000 |
| Standing seam metal | 50 to 70 years | $22,000 to $66,000 |
| Synthetic slate | 50+ years | $30,000 to $80,000 |
| Synthetic cedar (Enviroshake) | 50+ years | $30,000 to $68,000 |
| Cedar conversion to asphalt | 25 to 30 years | $18,000 to $40,000 |
| Townhouse strata (per unit) | 25 to 30 years | $8,000 to $18,000 per unit |
How long a Maple Ridge roof replacement takes
Standard single family homes, both established and newer, complete in 2 to 4 days. Custom rebuilds with complex geometry extend to 4 to 9 days, and larger custom and estate homes run 5 to 14 days. Standing seam metal projects run 6 to 16 days because panel fabrication and detailing take longer than shingle installation. Cedar conversion adds 2 to 4 days to a comparable replacement for the strip and deck preparation stages.
Two things commonly extend timelines beyond these ranges: discovered deck repairs, which add work once the sheathing is exposed, and heritage planning coordination on protected properties, which can add 4 to 12 weeks before work begins. Weather windows also matter in this climate, so crews sequence tear-off so that no more deck is exposed than can be dried in within the same working day.
Permits, the BC Building Code and the Maple Ridge Building Bylaw
Renovation and repair work on Maple Ridge homes must comply with the current BC Building Code and the Maple Ridge Building Bylaw, along with any other applicable bylaws. Whether a specific re-roofing project needs a building permit depends on its scope, so the reliable step is to confirm your project's permit requirements directly with the City of Maple Ridge permit office or through the City's Online Citizen Permit Portal before work begins. Structural changes, additions and scope beyond like-for-like re-roofing are the situations most likely to trigger permit requirements.
For commercial, industrial and multi-residential buildings in Maple Ridge, exterior alterations require a building permit, which is relevant to strata and commercial replacement scopes. Paragon builds code compliance and manufacturer installation requirements into every quoted scope, and can speak to the permitting question for your specific building during the estimate.
Completed Paragon roof replacements in Maple Ridge
You can review two completed Paragon Roofing BC replacement projects in Maple Ridge on this site. The River Road project is documented with a photo gallery following the work from the exposed deck through underlayment and shingle installation to the finished roof, including detail views at the chimney and skylight. Those photographs show why a replacement scope has to address more than the visible surface: the deck, membrane layers and penetration details all appear in the sequence. A second completed replacement on 229th Street in Maple Ridge is also published in our project archive.
These are the kinds of records worth asking any contractor for: not just a finished glamour shot, but evidence of how the work in the middle of the project was handled.
How strata and townhouse replacements differ from single family
Maple Ridge has substantial townhouse strata stock from the 1980s through 2010s, concentrated along the Lougheed Highway corridor and in Cottonwood, Albion and West Maple Ridge, and much of it is at first or second replacement cycle now. Strata replacement differs from single family in scale, governance and sequencing: projects typically run 2 to 12 weeks across phases, per-unit budgets run $8,000 to $18,000, and decisions flow through council approval rather than a single owner.
Paragon integrates strata depreciation report inputs into these projects, including current condition assessment, remaining useful life estimates, replacement cost projections, council presentation materials and phased multi-building scheduling around occupied homes. Strata councils and property managers can start with our dedicated strata roofing resources linked below.
The bottom line on Maple Ridge roof replacement
Replace when failure is system-wide, repair when it is local, and insist on a written scope that covers tear-off, deck assessment with per-sheet sheathing pricing, new flashing, ventilation correction and warranty terms before anyone sets foot on your roof. In Maple Ridge, your home's cohort shapes the right material: Class A options for WUI exposure neighbourhoods, character-compatible systems for Hammond heritage homes, and conversion pathways for aging cedar. Paragon Roofing BC quotes all of it with free on-site estimates, published pricing ranges, a 20 year workmanship warranty on residential replacements, and completed Maple Ridge projects you can review before you decide.

Custom rebuilds with complex geometry run 4 to 9 days, larger custom and estate homes run 5 to 14 days, and standing seam metal projects run 6 to 16 days. Cedar conversion adds 2 to 4 days. Townhouse strata projects typically run 2 to 12 weeks across phases, and heritage planning coordination on protected properties can add 4 to 12 weeks before work starts.
Do I need a building permit to replace my roof in Maple Ridge?
It depends on the scope of your project. Renovation and repair work in Maple Ridge must comply with the current BC Building Code and the Maple Ridge Building Bylaw, and permit requirements vary with what the project involves. Confirm your specific project's permit needs with the City of Maple Ridge permit office or the City's Online Citizen Permit Portal before work begins. Exterior alterations on commercial, industrial and multi-residential buildings do require a building permit.
What happens if rotten sheathing is found during my replacement?
Paragon quotes include a sheathing replacement allowance with per-sheet pricing stated before work begins. If damaged sheathing is found after tear-off, the affected sheets are documented, you approve the repair against the published per-sheet rate, and the project continues. This prevents the open-ended mid-project charges that cause most replacement cost disputes.
What warranty comes with a Maple Ridge roof replacement?
Paragon Roofing BC provides a 20 year workmanship warranty on residential replacements, covering the installation itself. The roofing materials carry their own manufacturer coverage in addition, and Paragon represents both CertainTeed Master Roofer and IKO Master Roofer credentials, which relate to manufacturer product and warranty programs. Ask for the specific workmanship and manufacturer terms in writing with your quote.
Has Paragon Roofing BC completed roof replacements in Maple Ridge?
Yes. Two completed Maple Ridge replacement projects are published on this site: a River Road replacement documented with a full photo gallery from exposed deck through finished roof, and a replacement on 229th Street. Both are linked from this page so you can review the work before requesting an estimate.
My Maple Ridge home has an old cedar roof. Is conversion part of a replacement?
Yes. Cedar conversion is a replacement pathway where the cedar is stripped, the substrate is prepared or corrected to accept a modern system, and asphalt, synthetic or metal roofing is installed. Conversion to asphalt typically runs $18,000 to $40,000 and adds 2 to 4 days versus a standard replacement. Owners who want to keep the shake appearance often choose Enviroshake synthetic cedar instead of asphalt.
