New construction
Start with the roof drawings, chosen covering and builder’s schedule. Confirm who is responsible for the deck, openings, inspections and adjoining work before installation begins.
PARAGON ROOFING BC · RESIDENTIAL
Residential roof installation
across the Lower Mainland
A new roof starts with a clear plan for the whole system. Bring us your existing roof, addition or new home plans and we will help define the work.
Paragon Roofing BC was established in 2020. Our team brings over 20 years of roofing experience.
START WITH THE RIGHT SCOPE
One home. A complete roofing system.
Residential roof installation brings the deck, protective layers, flashings, ventilation and roof covering together. On an existing home, the scope also needs to address removal, concealed damage and connections to the parts that remain.
Additions and garages
Check how the new roof joins the existing home. A change in slope, a wall junction or a low roof can call for a different assembly from the main roof.
Existing homes
Assess the current covering and deck before choosing the next system. If your roof is worn or leaking, see our roof replacement service for that part of the decision.

FROM FIRST LOOK TO FINAL CHECK
What belongs in an installation plan?
The exact sequence depends on the building and roofing product. These are the decisions and stages to establish in the written scope, rather than leaving them until the roof is open.
Assess the roof and agree the scope
Review roof shape, access, drainage, visible condition and your material preferences. For a new build, start with the drawings. Identify inclusions, exclusions and any investigation still needed.
Plan access, protection and removal
Agree on delivery and bin locations, clear access routes and protection for the property. For a replacement, specify which coverings and layers will be removed and how debris will leave the site.
Check the deck before covering it
The supporting deck must suit the selected system. Removal can reveal damaged or unsuitable sheathing. Establish how findings will be documented, priced and approved before additional work proceeds.
Coordinate protective layers and details
Underlayment, eave protection, roof edges and flashings must work with the covering. Valleys, wall junctions, chimneys and skylights need details suited to their location and the chosen assembly.
Install the covering and ventilation details
Use the product’s requirements for slope, fastening and accessories. Review intake and exhaust paths where the roof assembly requires ventilation, along with penetrations and drainage connections.
Finish, clean up and review the work
Include debris removal, a ground cleanup and a review of completed details in the scope. Keep the agreed product information and completion records so future maintenance starts with useful information.
MATERIAL CHOICES
Choose the system your roof can support
Appearance is one part of the choice. Slope, deck condition, structural capacity and the details around the roof also matter. Compare the proposed assembly, not just the visible surface.
On a small screen, swipe the table to compare options.
| Roofing option | What to establish | Explore the material |
|---|---|---|
| Asphalt shingles | Confirm the shingle profile, approved deck, slope, starter and ridge details. Fibreglass is a shingle reinforcement, not a separate roof category. | Asphalt shingle roofing |
| Cedar shakes and shingles | Review the supporting deck, ventilation and the selected cedar assembly. A change from cedar to another covering needs its own scope. | Cedar roofing |
| Metal roofing | Specify the panel or shingle system, fastening approach, roof edges and penetrations. Details vary between products. | Metal roofing |
| Synthetic slate or shake | Identify the actual product, deck requirements, fastening and compatible accessories. Different synthetic products are not interchangeable. | Synthetic roofing |
| Tile or natural slate | Confirm that the structure and supporting assembly are suitable before committing to the covering. | Clay tile roofing
Ask about natural slate suitability |
| Membranes for low roof areas | Garages and additions may need a membrane system. Include drainage, edge details and the connection to adjoining sloped roofing. | Discuss a low roof area |

DETAILS WORTH DISCUSSING
Look beyond the field of the roof
A broad roof surface can look straightforward while its junctions need careful planning. Include the surrounding condition when discussing an installation or a change of material.
A CLEARER QUOTE
What changes the installation cost?
A useful quote is based on your roof and an agreed scope. A price per square foot alone cannot show whether two proposals include the same work.
The roof itself
Size, slope, height, valleys and penetrations affect the work. Existing layers, deck condition and structural changes can change the scope.
The selected system
Covering, protective layers, flashings, vents and accessories should be named. Clarify whether skylight, fascia, gutter or chimney work is included.
Site logistics
Access, staging, waste handling, occupied areas and weather affect planning. Discuss parking, deliveries and the areas that need to remain usable.
Before comparing proposals, check these points
- Exactly what is removed, retained and installed.
- The product and assembly proposed for each roof area.
- Deck repair allowances or rates and the approval process for added work.
- Responsibility for permits, inspections and work by other trades.
- Property protection, cleanup, payment terms and completion records.
- Separate manufacturer product coverage from workmanship terms, including exclusions and any registration requirements.
Send photos taken safely from the ground, your address and any available drawings. There is no need to climb onto the roof to request a quote.

HOMEOWNER QUESTIONS
Before your installation begins
How long does a residential roof installation take?
The schedule depends on roof size and complexity, access, the chosen material, removal work, deck repairs and weather. Ask for the expected sequence and how changes or delays will be communicated after the roof has been assessed.
Does the old roof always need to come off?
That decision depends on the existing layers, deck condition, selected product and applicable project requirements. The quote should state what is removed and retained. Adding a covering over an existing roof does not provide the same view of the deck as removal.
Can I stay at home while the roof is installed?
Discuss occupancy with the team before work begins. Noise, vibration, falling debris zones and temporary access restrictions can affect daily routines. Plan for children, pets, vehicles and anyone who needs a quiet or accessible route.
What happens if damaged decking is found?
Ask for the finding to be documented and the proposed repair explained. Your quote should say how additional deck work is priced and who approves it. The extent of concealed damage may only become clear once the old covering is removed.
Can you discuss roofing for a new home or addition?
Yes. Share the drawings, roof material preferences, project address and builder or project contact. The roofing scope needs to be coordinated with the deck, openings, adjoining work and overall construction schedule.
Will my roof installation need a permit?
Confirm the requirements with the municipality for your exact scope before work begins. A new build, structural alteration or change of assembly can involve different requirements from replacing a covering. Record who is responsible for permits and inspections in the agreement.
Should gutters, skylights and ventilation be included?
They should at least be reviewed where they connect to the roof. Replacement is not automatically part of every quote. Identify which components remain, which change and how each connection will be completed.
How do I choose between roofing materials?
Start with the roof’s slope, structure, supporting deck and drainage, then compare appearance, maintenance needs and the complete installed scope. A material suited to the main roof may not suit a low addition or garage.
