Know what needs replacing. Know what your new roof includes.
A roof replacement removes the old covering, assesses the deck and installs a compatible new roofing assembly. We help you compare repair and replacement, understand the details beneath the surface, and agree on the work before it begins.
The important question is whether the problem can be addressed reliably in the affected area or whether the wider roof is deteriorating. A useful assessment separates visible findings from concealed conditions and explains the limits of a repair.
Repair, investigate or plan a replacement
What to consider
What it means for your roof
One leak or isolated damage
Check the source and the surrounding roof before committing to a full reroof. A focused roof repair in Burnaby
may be the appropriate next step.
Repeated leaks or widespread deterioration
Review the number of affected areas, previous repairs, covering condition and accessible deck. Replacement may be more practical when isolated work cannot address the broader problem.
Sagging, movement or damaged decking
Arrange an assessment of the affected structure and substrate. Covering the surface does not resolve an underlying support or moisture problem.
Moss, debris or an older roof
These are reasons to assess condition and drainage, not an automatic replacement verdict. Do not rely on a generic age threshold or a material lifespan estimate.
Changing from cedar or another material
Check deck suitability, roof slope, ventilation, weight and transition details for the proposed system. A material conversion needs its own preparation scope.

A LOCAL PROJECT RECORD
Monarch Street, Burnaby
Roof preparation and the shingled surface are different stages of the same project story. These photographs come from our documented Monarch Street job.
DECK EXPOSED
Existing boards and remaining roofing at the edge during preparation.
SHINGLES AND ROOF DETAILS
Grey shingle courses, ridge caps and roof vents on the same project.
Two quotes can name the same shingle and still describe different jobs. Compare the roof areas, preparation, details and exclusions before comparing the total.
The work behind a roof replacement
What to consider
What it means for your roof
Removal and disposal
Identify the roof areas and layers to be removed, disposal arrangements, access equipment and protection for the property.
Deck inspection and repairs
State the expected substrate, what can be assessed before removal and how additional damaged or unsuitable decking will be documented and approved.
Underlayment and roof edges
Name the compatible underlayment and any specified membrane areas, with the edge and valley details required for the actual covering and slope.
Walls, chimneys and skylights
Explain which flashing is replaced, which adjoining components are retained and how the roof connects to walls, curbs and penetrations. Separate roofing work from other trade repairs.
Ventilation and moisture
Review the existing roof and attic assembly. Identify intake and exhaust work where relevant, and distinguish ventilation changes from insulation or air sealing work.
Covering and accessories
List the product, profile, colour, compatible starter and ridge components, fastening approach and installation requirements.
Approvals and site arrangements
Confirm permit responsibilities, any strata approval, delivery and bin locations, access restrictions, occupied areas and temporary weather protection.
Closeout and warranty terms
Include cleanup, agreed inspection or completion records, product documentation, workmanship terms and any registration responsibilities.
FROM ASSESSMENT TO HANDOVER
The replacement process
01
Assess the roof and define the work
Review reported problems, visible roof details and available repair history. Identify areas that cannot yet be checked. Select the proposed system and put the scope, exclusions, approval responsibilities and schedule assumptions in writing.
02
Prepare and protect the property
Plan material deliveries, debris removal, access equipment and protection around the building. Agree how residents enter and leave, where vehicles move and how the exposed work will be protected if weather interrupts the job.
03
Remove the old roofing and review the deck
Removal exposes conditions hidden by the old covering. Review damaged boards or panels, fastening support and suitability for the selected system. Record necessary changes before installing over the affected area.
04
Build the compatible assembly
Install the specified underlayment, edge and flashing details, covering and accessories in the required sequence. Asphalt, metal and synthetic systems have different substrate, fastening and ventilation requirements. Follow the selected product instructions and applicable project requirements.
05
Clean up and review the completed scope
Review the accessible finished work, agreed cleanup and any remaining items. Keep the proposal, approved changes, product details, photographs and warranty documents together for future maintenance.
FROM PARAGON’S PHOTO LIBRARY
Look beneath the surface
Deck condition and roof details deserve their own discussion. These additional photographs from our roofing work show exposed decking and shingle details at different stages.
EXPOSED ROOF BOARDS
Weathered boards exposed during roof work. The substrate needs assessment before the new assembly is installed.
SHINGLE AND VENT DETAILS
Shingle courses and box vents, with a temporary timber board still on the slope. This is a work stage photograph.
CHOOSE FOR THE WHOLE ASSEMBLY
Roof options for your Burnaby home
Start with roof slope, existing construction, appearance, exposure and maintenance needs. Compare complete installed systems rather than assuming every material can use the same deck, membrane or flashing specification.
Material choices and the questions to resolve
What to consider
What it means for your roof
Asphalt shingles
A range of profiles and colours for suitable sloped roofs. Compare the actual shingle, deck preparation, starter and ridge accessories, fastening and ventilation details. Explore asphalt shingle roofing in Burnaby.
Metal roofing
Compare panel or shingle profiles, seam design, fastening, thermal movement, compatible underlayment and transitions. Material thickness and fastening schedules belong to the specified system. Explore Burnaby metal roofing.
Synthetic shake or slate
Compare the named product, approved roof slope, substrate, fastening, accessory system and maintenance instructions. Product ratings and warranty terms vary. Explore synthetic roofing in Burnaby.
Cedar replacement or conversion
Decide whether to retain a cedar system or change the covering. Check the deck and ventilation implications of that choice rather than assuming the existing boards are ready for new shingles. Explore cedar roof conversion in Burnaby.
Flat or low slope areas
Porches, additions and other low slope areas may need a separate membrane system and drainage details. Define those areas separately from the main sloped roof. See Burnaby flat roofing.
PLAN AROUND YOUR PROPERTY
Access, approvals and everyday life
Homes and occupied suites
Discuss parking, driveway use, pets, children, tenant notices and access to doors. Tell us about fragile landscaping, narrow side yards and items in the attic that may need protection.
Strata and shared roofs
Confirm who approves the scope and changes, which buildings or roof areas are included, and how residents receive updates. Coordinate shared access and records with the council or property manager.
Related improvements
Identify planned skylight, gutter, chimney, insulation or solar work early. Agree where the roofing scope ends and where another trade or separate approval is required.
Confirm the permit requirements for the actual work
Check with the City of Burnaby before work starts. Describe the property and any deck, framing, roof shape or chimney changes. A general statement that every reroof is exempt, or that every reroof needs the same permit, is not a substitute for checking your scope.
A PRICE BASED ON YOUR ROOF
What affects replacement cost?
The building and existing roof
Roof area, steepness, height, number of slopes and valleys, access and removal layers affect the work. Deck condition and details around skylights, chimneys and walls can change the scope once the old covering is removed.
The proposed assembly
The selected covering, substrate preparation, underlayment, ventilation, flashing and related work all belong in the comparison. Ask which items are included, which are allowances and which are excluded. Confirm how changes are approved.
Compare itemized proposals for the same roof areas and responsibilities. A generic price per square foot cannot show what your property needs. Product coverage and workmanship terms should also be compared separately from the total.
BEFORE YOU COMMIT
Burnaby roof replacement questions
Do I need a permit to replace my roof in Burnaby?
Confirm the requirements with the City of Burnaby for your address and exact scope before work starts. The City distinguishes minor non structural exterior repairs from alterations and restoration work, but its public guidance does not settle every reroofing situation. Describe any deck, framing, chimney or roof shape changes. Strata approval is a separate step.
Does a leak mean I need a complete replacement?
No. A leak may come from one flashing, penetration or damaged area. The assessment should locate the likely entry point, review surrounding materials and explain whether a repair can address the cause. Repeated leaks and widespread deterioration may justify replacement, but age or one ceiling stain alone is not a diagnosis.
Can new shingles go over the existing roof?
An overlay can leave the deck and older details concealed. Removal gives access to inspect the substrate and address damaged areas. Whether any overlay is suitable depends on the existing layers, roof condition, structural limits, local requirements and the selected product instructions. The proposal should state which approach is included and why.
Will all the plywood or roof boards need replacing?
Not automatically. The exposed deck needs assessment for condition, support and compatibility with the new roof. Sound existing material may be retained where suitable; damaged or unsuitable areas need a defined repair or replacement scope. A cedar conversion can require different deck preparation from a shingle replacement. Agree how concealed work is photographed, priced and approved.
How long will the work disrupt my home?
Roof size, access, removal layers, concealed damage and suitable weather affect the schedule. Ask for the expected work sequence, daily access arrangements, noise planning and temporary weather protection. Keep a contact available to approve necessary changes. A general day count is less useful than a schedule based on your property.
Can skylights, gutters or attic work be included?
They can be discussed as part of the proposed work, but they are not automatically included in every reroof. Identify whether a skylight is being replaced or only reflashed, which gutters or downpipes are affected, and what ventilation or insulation work is planned. Confirm any specialist trade responsibilities and exclusions.
What should I send when requesting an assessment?
Send the Burnaby address, property type, known roof material, leak locations and earlier repair or inspection records. Ground level photographs and interior stain photographs can help. Mention access restrictions, tenants, strata approval requirements and planned solar or renovation work. Do not climb onto the roof to gather photographs.
How do I compare warranties and maintain the new roof?
Read the actual product warranty and workmanship terms separately. Compare coverage, exclusions, registration responsibilities, transfer conditions and the claim process. Keep the proposal, product details, invoices and completion photographs. Follow the selected system’s care instructions and arrange appropriate checks after damage or recurring drainage problems; a warranty is not a promised service life.
