Asphalt shingles
A wide range of colours and profiles for suitable pitched roofs. Individual damaged areas may be repairable, depending on the surrounding condition and availability of compatible shingles.

Asphalt shingle roofing
in Delta
A sound roof starts below the shingles.
Paragon Roofing BC repairs and replaces asphalt shingle roofs in Delta. For a replacement, the important decisions are the condition of the deck, the roof slope, ventilation, flashings and the shingle system. A new surface should address the problems beneath it.
Tell us whether you have an active leak, damaged shingles or a roof you are planning to replace. We will discuss the next assessment step and explain the proposed work before you commit.
MATCH THE SYSTEM TO THE HOUSE
Where asphalt shingles fit
Asphalt shingles are an option for pitched roofs on homes across North Delta, Ladner and Tsawwassen. Architectural shingles create a layered appearance; other profiles offer different shapes and shadow lines. Compare actual samples alongside the siding, brick and trim.
Product selection needs more than a colour choice. Review the roof pitch, exposure, deck and installation requirements for the proposed shingle. Low slope sections may need a separate membrane system and careful transitions to the shingles.
Start with your roof, not a standard package
A shaded roof with debris in its valleys presents different maintenance concerns from an open, exposed roof. Dormers, skylights, chimneys and adjoining lower roofs also change the detail work.
For mixed roof areas, see our flat and low slope roofing in Delta. Our Delta roofing services page covers the wider range of work.
LET CONDITION GUIDE THE DECISION
Repair the defect or replace the roof?
A leak does not automatically mean the whole roof has failed. An assessment should trace the problem and consider the surrounding shingles, flashings and supporting materials.
| What you notice | What to investigate | Possible direction |
|---|---|---|
| A few missing or damaged shingles | Wind damage, fastening, sealing and whether nearby shingles remain sound. | A local repair may work if it addresses the cause and a compatible repair is practical. |
| A stain near a chimney, skylight or wall | The roof junction and flashing, rather than assuming the shingles alone are responsible. | Repair the relevant detail; explain any concealed areas that could not be checked. |
| Repeated leaks or widespread deterioration | The extent of wear, previous repairs, underlying moisture and deck condition. | Compare further repairs with a planned replacement and its complete scope. |
| Sagging or soft areas | Potential deck or structural damage, with appropriate professional input. | Establish the repair and any approval requirements before covering the area. |
For an active leak, call from a safe location and describe where water is appearing. Avoid climbing onto a wet roof. Response availability and temporary protection need to be confirmed for the actual situation.
TELL US WHAT YOU HAVE NOTICED
Arrange the next assessment step
Include your Delta address, the current roofing material, leak history and whether you are seeking a repair or replacement. Mention access restrictions and any previous reports.
We will discuss the assessment scope, any applicable fee and availability before arranging a visit.
THE COMPLETE REROOF
What belongs in a shingle replacement?
Removing the existing roofing exposes the deck for assessment and allows the new layers and details to be coordinated. The proposal should specify the removal depth and how concealed damage will be documented and priced.
| Component | What to make clear |
|---|---|
| Removal and deck | Roof areas and layers being removed, inspection of exposed wood, and the price or approval process for damaged sheathing. |
| Underlayment and eave protection | The specified products and where they will be installed, based on the roof conditions, applicable code and shingle instructions. |
| Shingles, starters and ridge caps | The exact product line, colour, matching components, fastening and sealing requirements. |
| Flashings and transitions | Valleys, walls, chimneys, skylights, vents, eaves and rakes. Identify which existing metal is replaced or retained and why. |
| Attic ventilation | Existing intake and exhaust, blocked airflow and the proposed changes. Adding exhaust alone does not explain the whole ventilation plan. |
| Site care and closeout | Deliveries, property protection, waste removal, cleanup, final review and the applicable warranty documents. |
Gutters, skylight replacement, fascia, insulation and structural repairs should be clearly included or excluded. See roof replacement in Delta for the wider replacement service.
Why not simply add another layer?
A recover can be considered in some circumstances, such as a single flat layer over a sound deck, subject to applicable rules and product requirements. Curled roofing, damaged decking or uncertain underlying conditions can make removal the better choice. An overlay should not be used to conceal a problem.
ROOF STYLES AND DETAILS
Look closely at the junctions
Water passes through valleys and around walls, vents and changes in roof slope. These details deserve as much attention in the scope as the shingle colour.
CHOOSE THE APPEARANCE AND THE ASSEMBLY
Asphalt, cedar or metal?
Cedar
A natural wood appearance with its own preparation, ventilation and maintenance needs. If changing to shingles, establish whether the existing deck is suitable for the new covering.
Metal
A different appearance and installation system. Panel profile, support, coating, attachment, movement and junctions need to be considered together for the building.
Compare complete proposals rather than assuming a fixed price or lifespan relationship between materials. Explore replacing a cedar roof in Delta and our guide to planning a roof replacement in Delta.
Compare the exact shingle line
Ask about appearance, current availability, installation requirements and written warranty terms. Algae resistant products are an option to discuss; they do not make a roof maintenance free. Confirm the product and any applicable coverage in your proposal.
PLAN THE JOB AROUND YOUR HOME
Cost, access and Delta requirements
The roof area, pitch, height, number of details, removal work and deck condition all affect cost. Access for materials and disposal also matters. A generic price range cannot establish the scope for your house.
Compare the same roof areas, products, flashing work and ventilation changes. Ask how taxes, allowances, exclusions and additional work are shown. Agree on changes before they proceed.
Permits and working days
The City of Delta lists roofing repair or replacement among work that does not require a building permit. Structural repairs, altered framing, new openings or broader renovations may change that answer. Confirm the actual scope with the City when needed; applicable code and zoning requirements still matter.
Plan work within Delta’s permitted construction hours. The City permits construction during specified weekday and Saturday hours and restricts it on Sundays and holidays. Weather, access and concealed repairs also affect the schedule.

CONDITION MATTERS MORE THAN A NUMBER
Service life and shingle care
Product selection, installation, exposure, ventilation and upkeep all affect how a roof ages. A warranty term is not a promise that every roof will remain serviceable for that length of time.
Arrange safe maintenance to keep gutters and roof drainage paths clear. Review damaged shingles, flashings and ventilation issues, especially after significant weather. Keep dated photographs and repair records.
Black streaks and moss are different
Dark streaks are commonly algae and are mainly an appearance issue. Moss can lift shingle edges and interfere with drainage. Neither should be diagnosed solely from a distant photograph.
Do not pressure wash or aggressively scrub shingles: this can remove protective granules. Ask for care methods compatible with the roof and local requirements. Some shingles use algae resistant granules; these do not eliminate maintenance.
ANSWERS FOR DELTA HOMEOWNERS
Asphalt roofing questions
How much does an asphalt shingle roof cost in Delta?
The price depends on the roof area, pitch, access, removal, deck repairs, product line, flashings and ventilation work. Request a written scope with allowances, exclusions and taxes, so you can compare proposals for the same work.
Can damaged shingles be repaired without replacing the whole roof?
Sometimes. A local repair may be practical if the surrounding shingles and deck are sound and compatible materials can be installed. Repeated leaks, widespread deterioration or concealed damage may call for a wider scope.
Do you remove the old shingles?
Removal lets the exposed deck be checked and the new roof details coordinated. A recover may be possible on a suitable existing roof, but the condition, applicable rules and product requirements must support it. Confirm the removal scope in writing.
What happens if rotten plywood is found?
Damaged decking needs to be addressed before it is covered. Your proposal should explain how concealed damage is documented, priced and approved. Structural concerns may require additional professional review or approvals.
Do I need a permit for shingle roof replacement in Delta?
Delta lists roofing repair or replacement as work that does not require a building permit. Structural repairs, altered framing, new openings and broader renovations can have different requirements. Confirm the actual scope with the City where needed.
How long will my new roof last?
Service life varies with the selected products, roof assembly, installation, exposure and maintenance. Assess the actual roof condition and read the product and workmanship warranties separately. A stated warranty period is not a guaranteed service life.
What causes black streaks on shingles?
Black streaks are commonly algae and mainly affect appearance. Moss is different and can lift shingle edges or affect drainage. Avoid pressure washing and aggressive scrubbing, which can damage protective granules; arrange a suitable assessment and care plan.
Can I change a cedar roof to asphalt shingles?
It may be possible, but the deck and supporting roof assembly must suit the new covering. Review deck preparation, ventilation, flashings and transitions as part of the conversion scope, rather than treating it as only a material swap.
