You notice a bare patch on the roof or several shingle edges lifting away from the surface. Does the damaged area need repair, or is it a sign that the whole roof needs replacing?
A few missing shingles and widespread curling are different conditions. The decision depends on what happened, how much roofing is affected and whether the surrounding shingles can accept a suitable repair.
For Toronto homeowners, the first step is to arrange an assessment of the affected area. Counting visible defects from the driveway is useful background, but it cannot establish the full repair scope.
Missing, lifted and curling shingles are not the same thing
Describe what you can see as accurately as possible.
Missing shingles leave an area where part or all of a shingle is absent.
Lifted shingles remain in place but appear raised or displaced.
Curling shingles have edges or corners that turn away from their intended position.
These observations do not establish the cause. A storm may be relevant to missing or disturbed roofing, while a broader pattern of curling may require consideration of the material and installation.
Note whether the change appeared suddenly or developed gradually. Tell the contractor if it followed strong winds, nearby work or a previous repair.
A close assessment should determine whether the concern is isolated or part of a wider condition.
Can individual missing shingles be replaced?
Sometimes. Manufacturers publish procedures for replacing individual asphalt shingles, demonstrating that localized replacement can be a legitimate repair approach. IKO’s guidance specifies that the replacement shingle must be the same size as the one removed.
However, the presence of a missing shingle does not establish that replacing only that piece will complete the job.
The contractor needs to assess the surrounding shingles, attachment points and accessible materials beneath the affected area. Nearby damage may not be obvious from the ground.
Ask whether the proposed work restores the whole affected detail or only replaces what is visibly absent.
If several shingles came loose in the same location, request an explanation of any installation or fastening concern identified. Otherwise, replacing the pieces may leave an unresolved problem.
Why does the condition of nearby shingles matter?
A repair involves working with the retained roofing around the defect.
If surrounding shingles are damaged or unsuitable to handle, the repair boundary may need to extend beyond the missing piece. The contractor should explain why additional shingles need removal or replacement.
Ask:
- Are the adjacent shingles suitable to retain?
- Can the repair be completed without damaging surrounding materials?
- What happens if additional damage is found during the work?
- Where will the finished repair begin and end?
Weather and material condition can also affect handling. GAF notes that shingles may crack or break when repair work is carried out in conditions that are too cold.
That does not make September a guaranteed repair window. Actual conditions and the requirements for the proposed materials still matter.
Can curling shingles simply be pressed down?
Do not assume that flattening a raised edge resolves the issue.
The contractor should establish whether the shingle is displaced, damaged or deformed, and whether a suitable repair is available. A treatment for an otherwise serviceable lifted shingle may not be appropriate for a deteriorated one.
Avoid climbing onto the roof to press, nail or glue the shingles yourself. Working on the visible symptom can damage the roofing or obscure evidence needed for assessment.
Ask what the proposed treatment corrects. Is the shingle being retained, replaced or included in a broader repair?
If the same curling pattern appears across much of a roof slope, request an overview of that condition rather than a recommendation based on one close-up photograph.
What needs checking beneath a missing shingle?
A gap in the roof covering makes the underlying condition part of the assessment.
Ask whether the accessible underlayment, fastening area or supporting surface shows damage. If these components cannot be fully assessed until work begins, the quote should explain that limitation.
GAF advises addressing missing shingles promptly rather than allowing the condition to remain unresolved.
You do not need to wait for an indoor leak before requesting help. The absence of staining does not establish that everything beneath the gap is unaffected.
If concealed damage is found, ask for photographs and a description before additional work is approved. The record should distinguish newly discovered conditions from the original visible defect.
Will new shingles match the existing roof?
A repair can be technically suitable while remaining visible.
The existing shingles may have weathered, and the original product or colour may no longer be available. GAF’s warranty documentation notes that product changes or discontinuation can mean replacement materials are not an exact match.
Discuss appearance before work begins, particularly for a prominent front slope.
Ask the contractor to identify the proposed replacement and explain its compatibility with the retained roof. A similar colour name alone does not establish a suitable match in size, construction or installation requirements.
If appearance is important, ask what difference is reasonably expected. Avoid assuming that a small repair will become invisible after a few months.
Does damage near a chimney or valley change the repair?
It can change what needs investigating and the scope of the work.
A damaged shingle beside a roof junction may be only one part of the concern. Flashing, transitions or other details may need assessment too.
Tell the contractor if there is an indoor stain nearby, but do not assume its position confirms the entry point.
A roof inspection can help determine whether the visible shingle damage is isolated or connected to another roofing detail.
The proposal should identify related work explicitly. Replacing shingles beside a chimney does not automatically include chimney flashing repair.
When does the pattern suggest a broader problem?
Broader work deserves consideration when defects occur across several areas, retained shingles are unsuitable for repair or previous localized work has not resolved the concerns.
Ask for evidence showing the distribution of damage. Overview photographs can help distinguish one affected patch from widespread deterioration.
Useful questions include:
- Which roof sections show the problem?
- Are the findings similar across those sections?
- Why would localized repair be insufficient?
- Can one slope or separate section be treated?
- What remains uncertain beneath the covering?
Age provides context, but it should not be the only reason given for replacement.
Apple Roofing’s shingle roofing services include installation, repair and replacement. The recommendation should follow the condition and repairability of your roof.
What if the shingles are damaged but the roof is not leaking?
Arrange an assessment rather than treating a dry ceiling as confirmation that the damage can wait indefinitely.
Explain whether the area is missing material, visibly lifted or curling. Provide safe ground-level photographs and the date you first noticed it.
Ask the contractor to recommend timing based on the findings. An exposed area, a stable-looking but uncertain defect and an active leak may require different responses.
If water is entering, report that immediately when booking. Keep away from bulging ceilings and wet electrical fittings, and protect belongings only where it is safe.
Do not attempt an improvised repair from a ladder while waiting for the visit.
What should a localized repair quote include?
A clear proposal should define the work area and the materials being used.
| Quote item | What to confirm |
|---|---|
| Repair location | Roof slope and affected area |
| Shingle replacement | Proposed product and extent of work |
| Underlying materials | Assessment or replacement included |
| Adjacent details | Flashing or other work included or excluded |
| Appearance | Expected difference from retained shingles |
| Additional findings | Approval and pricing process |
| Completion | Photos and applicable workmanship terms |
If a contractor recommends a temporary measure, ask what permanent work remains.
For roof repair and maintenance, compare proposals covering equivalent areas and tasks. A quote for replacing a few shingles is different from one that also corrects an adjoining detail.
What should you expect after the repair?
Request a record identifying the completed area and any remaining recommendations.
Completion photographs are useful, especially where the repaired section cannot be seen clearly from the ground. Keep them with the invoice and previous roofing documents.
A local repair addresses its agreed scope. It should not be interpreted as certification that every part of the roof is free of defects.
Ask whether another area needs monitoring or further assessment. If the same section develops new damage or leaking, provide the earlier repair records when reporting it.
For a storm-related event, retain the original photographs as well as the completed-work record.
Arrange an assessment before choosing the scope
Missing or curling shingles do not automatically mean full replacement. They do mean the affected roofing needs a closer assessment.
Send us safe photos, the approximate date the problem appeared and any previous repair information. We can assess the area and explain whether localized work is suitable or a broader scope needs consideration.

Frequently Asked Questions
Can a few missing shingles be replaced without replacing the roof?
Sometimes. The surrounding shingles, underlying materials and replacement compatibility need assessment. A localized repair may be suitable if it can restore the affected area without leaving another identified problem unresolved.
Do curling shingles always mean the roof needs replacement?
No. The extent, condition and repairability matter. Ask whether the curling is isolated or widespread and what findings support retaining, repairing or replacing the affected roofing.
Will replacement shingles match the existing colour?
An exact match is not guaranteed because existing shingles weather and products can change or be discontinued. Discuss the proposed compatible material and expected appearance before approving the repair.
