Shingle Roofing in Toronto & the GTA
Asphalt shingles remain a familiar roofing choice for many homes. What the right solution looks like depends on the condition of the roof, its structure and details, and the roofing system beneath the visible shingles.
The material
Why Homeowners Consider Asphalt Shingles
Practical reasons shingles come up in most residential roofing conversations — without the claims that usually get attached to them.
The decision
Choosing a Shingle Roof Is More Than Choosing a Colour
What you choose
The visible decisions
- Appearance — how the roof sits against the rest of the house
- Budget — scope and material selection both move the number
What the roof determines
The conditions you inherit
- Roof geometry — hips, valleys, dormers and changes of direction affect how the roof is put together
- Slope — pitch influences what is appropriate and how the roof is detailed
- Existing condition — what is already on the roof shapes the scope of the work
- Ventilation — how the roof space breathes is part of the roofing conversation, not separate from it
- Flashing and penetrations — chimneys, vents, valleys and other transitions require careful detailing as part of the roofing system
- Drainage — where water goes once it leaves the roof surface
- Underlayment and supporting layers — the layers beneath the visible shingles
Underneath
Shingles Are Part of a Roofing System
The shingles are the visible layer. How the finished roof performs also depends on the condition and detailing of the assembly beneath and around them.
Shingles
The visible surface, and the part most homeowners are choosing between.
Underlayment and supporting layers
What sits between the surface material and the structure below it.
Roof deck
The structural surface the roofing is fixed to. Its condition often only becomes visible where existing materials are removed.
Detailed into that assembly
This is a general description of how sloped residential roofs are assembled. The components used on any particular project are set by that project’s confirmed scope.
Condition
When Should a Shingle Roof Be Looked At?
These are the things homeowners usually notice first. What they mean for the roof varies.
Selected Shingle Roofing Work
What to expect
What a Shingle Roofing Project May Involve
Roofing projects differ. This is the general shape of one, not a fixed procedure.
The existing roof is assessed
On site, looking at the roof as it currently stands.
Scope is determined
What the work needs to cover, based on what the assessment finds.
Existing materials are addressed as required
Depending on the agreed scope and the condition of what is already there.
Deck condition becomes visible where materials are removed
Some things can only be confirmed once the surface is off, which is why scope can be refined during the work.
Roofing components are installed to the confirmed scope
Surface material and the supporting components the project calls for.
The finished roofing is reviewed
A look over the completed work before the project is closed out.
Scope
Does Shingle Damage Mean the Whole Roof Needs Work?
Not necessarily.
Damage in one area does not automatically set the scope for the whole roof.
Roof Repair →What is appropriate depends on where the visible damage is and how far it extends, the age and condition of the roof, the state of the roofing next to the affected area, flashing and penetrations, the condition of the deck where it can be seen, any evidence of water movement, and how the roof reads overall.
Need help with a specific leak or damaged area?
If the concern is one spot rather than the whole roof, that is a different conversation.
Cost
What Affects the Cost of Shingle Roofing?
No two roofs price the same way. These are the variables that move the number.
- Roof size — the area the work has to cover
- Roof geometry — valleys, hips and dormers add complexity
- Slope — pitch affects how the work is carried out
- Access — how the property and roof can be reached
- Existing roofing condition — what is already on the roof
- Amount of work required — the scope the roof actually calls for
- Roof deck condition — where it can be seen or becomes visible
- Flashing and penetrations — chimneys, vents, valleys and openings
- Ventilation work — where the project calls for it
- Material selection — once the choice is confirmed
- Removal and disposal — where existing materials have to come off
Comparing options
Considering Shingles or Metal?
Shingles
- A familiar residential appearance on most streets
- Different material and project economics
- A practical option for many sloped residential roofs
Metal
- A different appearance and different roofing-system considerations
- Different project and material economics
- May suit homeowners evaluating a different long-term roofing approach
Which one fits depends on the specific roof and what the homeowner is trying to achieve. Both are worth looking at before deciding.
Questions
Shingle Roofing FAQ
How do I know whether damaged shingles need repair or more extensive roofing work?
It depends on where the damage is, how far it extends, and what the rest of the roof looks like. Damage confined to one area does not automatically mean the whole roof needs work, and a roof that looks acceptable from the ground can still have issues at the details. The appropriate scope depends on the condition of the affected area and the surrounding roof, which can be discussed as part of the estimate process.
Can individual damaged shingles be addressed?
In many cases localized areas can be addressed as part of the work, depending on the condition of the surrounding roofing and what the assessment finds. Whether that is the right approach for a particular roof is part of the estimate conversation.
What affects the cost of shingle roofing?
Roof size and geometry, slope, access, the condition of the existing roofing, the scope the roof requires, deck condition where it can be seen, flashing and penetrations, any ventilation work, the material selected once confirmed, and removal and disposal where existing materials have to come off.
What is underneath asphalt shingles?
Generally the shingles sit over underlayment and supporting layers, which sit over the roof deck — the structural surface the roofing is fixed to. Flashing, vents, valleys and other penetrations are detailed into that assembly. The specific components on any project are set by that project's confirmed scope.
Can roof deck problems be seen before roofing materials are removed?
Not always. Some deck conditions only become visible once the existing surface comes off, which is why scope can be refined during the work rather than fixed entirely in advance.
How do shingles compare with metal roofing?
They differ in appearance, in the roofing-system considerations involved, and in project and material economics. Which suits a property depends on the roof itself and what the homeowner is trying to achieve, so it is worth looking at both.
