Choose the right scope for your roof, from a local repair to a complete replacement.
Paragon Roofing BC installs, repairs and replaces asphalt shingle roofs across the Lower Mainland. Start with the condition of the roof, then compare the materials and work that suit your property.
Explore shingle styles, understand what belongs in a roof proposal and find the relevant local service page.
The shingle surface is one part of the roof. Vents, flashings and junctions also need a defined scope.
START WITH THE CONDITION
Repair, replace or install a new shingle roof
A missing shingle and an ageing roof call for different conversations. The first step is to understand the condition, identify the affected areas and agree on the purpose of the work.
Asphalt shingle repairs
A local repair may suit isolated damage where the surrounding roof remains serviceable. Ask how the cause was identified, which components need attention and whether matching materials are available.
Replacement deserves consideration when deterioration is widespread, repairs are difficult to integrate or repeated problems remain unresolved. A proposal should define removal, preparation and the new roof system.
For new construction or an addition, coordinate the shingle specification with the roof design, supporting deck, ventilation and adjoining assemblies. Confirm which roof areas are suitable for the proposed product before choosing a colour or profile.
Water entering now?
Contact a roofer promptly and describe the location and timing of the leak. Keep clear of electrical hazards and damaged ceilings. Gather existing records or photos from safe locations; do not climb onto the roof to investigate.
COMPARE THE OPTIONS
Three common asphalt shingle styles
Shingle names describe appearance and construction, but they do not establish the performance of every product in the category. Compare the exact product, installation requirements and written warranty terms.

Asphalt shingle style comparison
Style
Appearance
What to compare
3 tab or strip
A relatively flat profile with a repeating tab pattern.
Product availability, suitability for the roof and compatibility with existing shingles when planning repairs.
Architectural or laminated
A layered construction with a more dimensional appearance.
The named product, colour blend, roof details and the complete installed scope.
Designer or premium
Distinctive profiles that may resemble other roof coverings.
The specific profile, product requirements, availability and installed cost for the property.
An impact rating, wind rating or warranty period belongs to a particular product and its conditions. Do not infer one from a style name. Read our architectural versus 3 tab shingle comparison
for more help with the choice.
Review physical samples alongside the exterior colours. A screen image cannot show exactly how a finished roof will look in different light. If a repair is planned, discuss whether a visible difference between old and new material is likely.
Chimneys, roof edges and penetrations need attention alongside the shingles.Valleys and changes in roof direction influence detailing, material quantities and the work involved.

LOOK BEYOND THE SURFACE
What belongs in the roof system scope?
A roofing proposal should explain more than the shingle brand. Ask how the covering connects to the deck, water shedding details and ventilation arrangements. Each component should suit the actual roof and the selected product requirements.
On a small screen, scroll the table sideways to read every column.
Asphalt roof scope checklist
Component
What the proposal should explain
Question to ask
Existing covering and deck
What will be removed and how the exposed deck will be assessed.
How will concealed damage be documented and additional work authorised?
Underlayment and protection
The materials proposed beneath the shingles and at vulnerable areas.
Which products and locations are included in this roof specification?
Flashings and penetrations
Work at walls, chimneys, valleys, vents and other interruptions.
Which details are being replaced, retained or excluded, and why?
Shingles, starters and caps
The named shingle product and compatible edge and ridge components.
Are the accessories and detail requirements included in the price?
Ventilation and drainage
The condition and proposed treatment of vents, eaves and water paths.
What related work is needed and who is responsible for it?
Hidden conditions may only become clear after removal. Agree in advance on how changes will be recorded, priced and approved. Structural concerns or complex building connections may need additional professional assessment.
For more background, read our Vancouver asphalt shingle planning guide. A general guide supports the discussion; the project specification should address your building.
MAKE THE DECISION WITH EVIDENCE
When does a repair stop being the right fit?
Roof age provides context, but it does not settle the decision. Consider the spread of damage, the condition of adjacent shingles, previous repairs and the ability to integrate new materials. A stain inside the building may be some distance from the point where water enters.
Ask the assessment to separate observed conditions from suspected causes and areas that could not be inspected. If the cause is uncertain, further investigation may be more useful than choosing a repair or replacement immediately.
A defined local repair
Clarify the affected area, intended result and limitations. Ask whether the work addresses the source of the problem and what surrounding conditions remain. Retain photos and the written scope for future reference.
A broader replacement
Compare the proposed removal, deck work, flashings and ventilation with the condition findings. Ask how adjoining roof sections and any retained components will connect to the new work.
Can new shingles go over an existing roof?
Do not assume an overlay is suitable or permitted for your property. The existing assembly, deck condition, loading, local requirements and product instructions need review. Ask why removal or retention is being proposed and how concealed conditions would be assessed.
COMPARE THE WHOLE PROJECT
What affects asphalt roofing cost?
The useful number is a written price for a defined scope. Roof area matters, but so do the roof shape, access, removal requirements and details that interrupt the surface. A generic price per roof or per square foot can leave important work unexplained.
Roof and material choices
Pitch, valleys, dormers and penetrations affect the work involved. The selected shingle and accessories, existing layers, deck condition and related ventilation or flashing work also influence the proposal.
Access and site arrangements
Deliveries, material handling, disposal, protection of surrounding areas and occupied building access can change the plan. Identify parking restrictions and shared driveways before the scope is finalised.
Read the inclusions before comparing totals
Ask each proposal to identify the roof areas, products, removal, disposal, preparation and finish details included. Check exclusions, allowances, taxes, payment terms and the process for approving additional work. Resolve differences before treating two totals as directly comparable.
A proposed start date and duration should reflect the actual project. Weather, material availability, access and concealed damage can affect the sequence. Ask how delays and temporary weather protection will be managed.
FROM ENQUIRY TO HANDOVER
A practical sequence for your roofing project
Share the property details
Describe the roof concern, location, building type and any previous work. Identify the person who can approve decisions and provide access.
Review the findings
Discuss the condition, assessment limits and options. Clarify why the recommended scope suits the roof and what remains uncertain.
Agree on the written work
Confirm products, details, responsibilities, site arrangements and the process for changes before work starts.
Keep the completion records
Retain the final scope, approved changes, product information, written warranty terms and care instructions. Record any outstanding items and their resolution.
HOMES AND SHARED BUILDINGS
Plan around the people using the property
Roof work affects access, parking, noise and deliveries. For an occupied home, agree on where vehicles and materials can go and which areas need protection. Keep residents, visitors and pets away from the work zone.
For strata or multifamily buildings, establish a single project contact and confirm the approval process before accepting work. Identify the buildings and roof sections included, how residents will receive updates and how access will be maintained.
Shared roofs need a plan for access, deliveries and communication with residents.Different coverings and raised features create transitions to include in the roof assessment.
These roof views illustrate building layouts and details to discuss. The scope for your property should come from its own assessment and written proposal.
FIND YOUR LOCAL SERVICE PAGE

Use the regional information here to understand the service and material choices. For local enquiries, start with the relevant city page below.
For another Lower Mainland location, include the city and property address in your enquiry so the team can confirm service availability and the next step.
AFTER THE WORK
Keep the warranty and maintenance details together
Review the product warranty and written workmanship terms for the proposed roof. Check the coverage, exclusions, responsibilities and any registration or transfer steps. A warranty period is not a prediction of how long every roof will last.
Use the product care instructions and the roof condition to plan future inspections and maintenance. Report new leaks, displaced shingles or changes seen from safe locations. Arrange professional roof access rather than attempting repairs or cleaning from the roof yourself.
Keep product names, colours, invoices, photos and repair records together. They can help with later maintenance, matching materials and discussions about the work that was completed.
COMMON QUESTIONS
Asphalt shingle roofing questions
Does Paragon Roofing BC repair asphalt shingle roofs?
Yes. Paragon Roofing BC handles asphalt shingle repair enquiries as well as replacement and installation. The appropriate scope depends on the condition, cause of the problem and ability to integrate a repair with the existing roof.
Are architectural and laminated shingles the same category?
These terms commonly describe layered asphalt shingles with a dimensional appearance. Compare the exact product specifications, accessories and warranty terms rather than relying on the category name alone.
How much does an asphalt shingle roof cost?
Cost depends on the defined work, including roof size and shape, materials, removal, deck condition, details and access. Request a written proposal with inclusions, exclusions and a process for additional work.
How long will installation take?
The schedule depends on the roof, scope, access, weather and material availability. Ask for a proposed sequence and an explanation of how delays or concealed conditions will be handled.
Can I replace only the damaged shingles?
Sometimes, where damage is isolated and the surrounding roof remains suitable for a repair. Material availability, matching, underlying damage and the cause of the problem need assessment.
Can asphalt shingles be installed over an existing roof?
Do not assume an overlay is suitable or permitted. The assembly, deck condition, loading, local requirements and product instructions need review. Ask why removal or retention is proposed for the property.
Does an impact rated shingle guarantee lower insurance premiums?
No. Ask your insurer whether a particular product and installation qualify under your policy before relying on any saving. A product rating alone does not establish eligibility or a discount amount.
How long should an asphalt shingle roof last?
There is no single lifespan that applies to every roof. Product selection, installation, exposure, ventilation, maintenance and the building condition all matter. Use a current assessment to plan repairs or replacement.
What warranty information should I request?
Request the product warranty and written workmanship terms. Review coverage, exclusions, responsibilities and any registration or transfer requirements, and keep those documents with the project records.
What should I include in my roofing enquiry?
Include the city, property type, roof concern and whether water is entering. Mention previous repairs, available reports and access restrictions. Use existing photos or safe ground level views; do not climb onto the roof to collect information.
