Is asphalt right for your roof?
Asphalt shingles are a water-shedding roof covering. Their suitability depends on the roof design and the requirements of the selected product, not simply whether the house currently has shingles.
An extension or lower roof section may need a different system from the main roof. During an assessment, identify these areas separately and discuss how the materials will meet. The same finish doesn't need to cover every part of the building if the roof conditions differ.
For a complete re-roof, start with the roof replacement process. This page focuses on the decisions specific to a shingle roof.
Choosing the finish without overlooking the system
Colour and profile affect the appearance of the roof, but they should be considered alongside the proposed construction. Bring reference photos and explain whether you're trying to match an existing section or change the appearance of the whole house.
Ask which shingle options are available for the project and what distinguishes them. Product names, warranty labels and marketing descriptions don't replace an explanation of the exact material being quoted.
We don't assume that the same shingle is right for every home. A recommendation needs to account for the roof's pitch, details and exposure, as well as the finished appearance you're after.
What sits beneath and around the shingles
The underlayment provides a further layer of protection beneath the covering. Flashing helps direct water at roof edges, walls and openings. Valleys need detailing for the water arriving from adjoining roof slopes.
NorthVan Roofing's shingle work includes underlayment and valley protection, flashing, ridge and edge details, and a ventilation review. The estimate should identify which items are included for your roof and how any retained components connect to the new work.
Pay particular attention to skylights, vents and changes in roof level. A tidy shingle pattern isn't enough on its own if those connections haven't been addressed.
Repairing damage or renewing the roof
Missing shingles, cracking, curling or noticeable areas of granule loss are reasons to request a condition check. Those observations don't all mean the same thing, and a photograph alone isn't a replacement decision.
Localized roof repairs may be appropriate when the fault is limited and the adjoining materials can support a sound repair. More widespread wear calls for a discussion about whether repeated patching is still worthwhile.
Appearance matters during a repair too. Ask about the availability of a compatible shingle and whether the repaired area is likely to look different. An older roof may not have an exact visual match among current options.
Questions to settle in a shingle estimate
Before comparing prices, check that you're comparing the same roof sections and work. Ask whether the proposal includes removal of the existing covering, deck review, new underlayment and the relevant flashing details.
Clarify the treatment of valleys, edges, vents and skylights. Ask how concealed damage would be handled and what information will identify the product actually installed. Any warranty discussion should distinguish the manufacturer's terms from the contractor's workmanship terms.
If you're also considering another finish, compare metal roofing using the same roof area and a clearly defined scope. That makes the comparison more useful than looking at surface materials alone.
Asphalt shingle questions
Can new shingles match an older roof?
A close match may be possible, but it shouldn't be assumed. Existing shingles weather, and product lines or colours may differ from what was originally installed. Discuss compatibility and appearance before approving a visible repair.
Should I choose architectural shingles?
Treat architectural shingles as an option to discuss, not an automatic upgrade. Ask which products are available, whether they suit the roof and what their specifications actually cover. The full system and installation details still matter.
Do shingles work on a low-slope addition?
The selected product's slope requirements need checking. A section that looks similar from the ground may need a different covering and different connection details. Don't assume that extending the main roof's shingles onto it is appropriate.
Is there a reason to inspect a shingle roof that isn't leaking?
Yes. Roof condition inspections can review visible wear and details that need attention before you commit to repairs or replacement. Not seeing an interior stain doesn't establish the condition of the entire roof.
