If you have collected roofing quotes in Ontario recently, there is a good chance at least one of them named Owens Corning Oakridge shingles. Oakridge is one of the most widely installed laminated asphalt shingles in Canada, and it often appears as the standard option on a quote, with Duration offered as the upgrade. Knowing what the product actually is, and what it is not, helps you compare quotes on equal terms and ask better questions.
The shingle name on a quote tells you less than most people assume. Two Oakridge roofs can perform very differently depending on nailing, starter strips, eave protection and ventilation, and the warranty depends on those details too. Product details here come from the manufacturer’s Canadian literature at the time of writing; always confirm against the current documents, because product lines and colour offerings change.
What Owens Corning Oakridge Shingles Are
Oakridge is a laminated shingle, also called an architectural or dimensional shingle. Each shingle is made from two layers of asphalt-coated glass fibre mat bonded together, with the lower layer showing through cut-outs in the upper one. That two-layer build creates the staggered, shadowed look that distinguishes it from older three-tab shingles, and it adds weight and stiffness.
Owens Corning positions Oakridge as a step up from three-tab and below its Duration series. The Canadian data sheet highlights a full double layer of material in the nailing zone. The point is that nails driven through that zone pass through both laminated layers, which the manufacturer says gives better holding power than shingles with a wide, single-layer nailing area.
Key specifications from the Canadian data sheet
- Size: about 13 1/4 by 39 3/8 inches, installed with a 5 5/8 inch exposure.
- Coverage: three bundles average 64 shingles and about 98.4 square feet, which is roughly one roofing square.
- Standards listed: including CSA A123.5, ASTM D3462, Class F and Class H wind resistance test standards, and a Class A fire resistance rating.
- Algae resistance: StreakGuard granules intended to resist the black streaks caused by blue-green algae.
CSA A123.5 is the Canadian standard for asphalt shingles made with glass fibre mats, so seeing it listed is a useful sign that the product sold here is documented for the Canadian market.

Oakridge Colours Sold In Ontario
The current Canadian data sheet for Owens Corning Oakridge shows six colours. The descriptions below are general impressions; judge them with a real sample.
| Colour | General look | Often paired with |
|---|---|---|
| Onyx Black | Deep charcoal to near black | Modern exteriors, black window frames, white or light grey siding |
| Estate Gray | Mid to dark grey blend | Red or grey brick, stone, white and grey siding |
| Driftwood | Warm grey-brown blend | Beige or buff brick, earth-tone siding |
| Brownwood | Red-brown blend | Warm red brick, cream trim |
| Desert Tan | Light, sandy blend | Light brick and pale siding on lower-profile homes |
| Teak | Muted brown blend | Brown brick and wood-tone accents; the data sheet notes it is unavailable in one Canadian region outside Ontario |
Colour availability can still vary by supplier and season, so ask your contractor to confirm stock before you commit. The manufacturer itself recommends looking at an actual shingle sample in daylight and, ideally, a finished roof in the same colour, because printed and on-screen swatches never match perfectly. A practical tip: look at samples on the side of your house that faces the street, at different times of day. Blended colours like Driftwood and Estate Gray can read warmer or cooler depending on light and on the brick beside them.
Matching hip and ridge shingles are made to coordinate with Oakridge colours. Using the manufacturer’s own hip and ridge product also matters for the warranty, as explained below.
How Owens Corning Oakridge Compares With Duration
Most Ontario quotes from contractors who use Owens Corning products will offer one of these two lines. Both are laminated shingles of the same nominal size, and both carry a Limited Lifetime warranty in Canada. The differences are in construction, wind performance with standard nailing, colour range and price.
| Feature | Oakridge | Duration (general) |
|---|---|---|
| Shingle type | Laminated, double layer in the nailing zone | Laminated with SureNail engineered fabric strip in the nailing zone |
| Wind resistance limited warranty | 177 km/h with standard four-nail application; 209 km/h with six nails plus Owens Corning starter at eaves and rakes | 209 km/h standard, higher when the manufacturer’s component and starter requirements are met |
| Colour range in Canada | Six colours on the current data sheet | A larger range with the TruDefinition colour platform |
| Impact resistance | No impact class listed on the Canadian data sheet | Listed as Class 3 impact resistance |
| Algae resistance | StreakGuard, 25-year algae resistance limited warranty | StreakGuard, 25-year algae resistance limited warranty |
| Typical position on a quote | Standard laminated option | Upgrade option at a modest premium |
What the differences mean in practice
For a typical GTA house with average wind exposure, a correctly installed Owens Corning Oakridge roof performs well, and many homeowners never need more. Duration makes more sense if the house is exposed, such as a corner lot, a tall two-storey with no wind shelter, or a site near open fields or water, or if you want a stronger contrast between light and dark granules. The Class 3 impact listing on Duration may interest owners under heavy tree cover, although it is not the same as a fully impact-rated premium shingle.
If you choose Owens Corning Oakridge and want the higher wind rating, ask for six-nail application and the manufacturer’s starter shingles at both the eaves and the rakes. The extra labour is small compared with the total job.
Installation Details That Matter With Owens Corning Oakridge
A shingle is only as good as the way it is installed. The manufacturer’s instructions are specific, and the warranty depends on following them. These are the points worth checking on any quote or during the job.
The deck and underlayment
- A sound, flat deck. The instructions call for a properly built wood deck with adequate nail-holding capacity. Soft, delaminated or rotted sheathing should be replaced, and a quote should say how that is priced.
- Eave protection. A self-adhered ice and water barrier along the eaves is standard practice in Ontario, where ice damming is common. Building code requirements also apply, so confirm the details with your contractor and municipality.
- Underlayment on the rest of the roof. A synthetic underlayment is typically installed over the remaining deck. Low slopes, from 2:12 up to 4:12, need extra underlayment layers or full self-adhered membrane under the manufacturer’s instructions.
- Drip edge and flashing. New metal drip edge at eaves and rakes, plus new step and counter flashing at walls and chimneys, are part of a proper reroof rather than optional extras.
Nailing and layout
Fasteners must land in the designated nailing area so they pass through both layers of the shingle. High nails miss the double layer and can let shingles slide or blow off; low nails show through the course above and leak. Nails need to be the type and length the instructions specify, driven flush rather than overdriven or angled. Shingles are laid with a staggered offset between courses so joints do not line up.
Cold-weather installation
Shingles rely on a factory sealant strip that activates with warmth from the sun. In cool autumn weather, sealing can take longer, and the manufacturer’s instructions add steps such as hand-sealing shingles around the roof perimeter with asphalt cement and handling bundles with extra care below certain temperatures to avoid cracking. Installing in mid autumn is entirely normal across the GTA, but ask how your contractor handles sealing if the job runs into cold days.
Repairs and additions on an existing Oakridge roof
If you already have an Owens Corning Oakridge roof and need a repair or an addition tied in, expect some colour difference. Shingles weather over time, and the installation instructions warn against mixing material with different lot numbers because blends can vary between production runs. For a small repair, a roofer may pull matching shingles from a less visible slope and put new ones there. For an addition, it can look better to finish a whole slope in new material so the change falls on a natural break such as a valley or ridge.
Ventilation
An attic that cannot breathe cooks shingles from below in summer and builds frost and moisture in winter. Balanced intake at the soffits and exhaust at or near the ridge is the goal, and ventilation must meet local code. Our attic ventilation and insulation work is often done alongside a reroof for this reason.
Understanding The Owens Corning Oakridge Warranty
Warranty language is where sales pitches often blur the details, so it is worth reading the manufacturer’s actual document. In general terms, the Canadian literature describes a Limited Lifetime warranty on Oakridge for as long as you own your home on residential projects, a wind resistance limited warranty tied to how the shingles are nailed, a 25-year algae resistance limited warranty, and a non-prorated TRU PROtection period at the start of the coverage.
A few points owners often miss:
- Limited means limited. Coverage typically focuses on manufacturing defects, with conditions and proration after the initial period. It does not cover poor installation, storm damage beyond the stated limits or problems caused by inadequate ventilation.
- Installation must follow the instructions. The manufacturer states that it is not responsible for problems arising from deviations from its application instructions.
- Accessories can matter. The algae resistance coverage notes that an approved Owens Corning hip and ridge product must be used. Upgraded system warranties generally require a specific set of the manufacturer’s components and, in some cases, a contractor in its network.
- Transfer rules apply. Coverage when the house is sold is usually reduced or subject to conditions. Read the current document before relying on it in a sale.
- Workmanship is separate. The roofer’s own workmanship coverage is a separate promise from the manufacturer’s material warranty, so ask each contractor for theirs in writing.
Read the current Canadian warranty documents from Owens Corning directly, and keep a copy with your invoice, the product name, colour and the date of installation.
Cost Considerations For An Oakridge Roof
The shingle itself is only one part of the price. Tear-off, disposal, deck repairs, underlayment, ice and water barrier, flashing, vents, roof pitch and access often move the total more than the choice between two shingle lines. The figures below are broad estimates for typical GTA homes and will vary by house and scope.
| Roof type (asphalt tear-off and reroof) | Estimated range in CAD | Main price drivers |
|---|---|---|
| Small bungalow, simple gable, moderate pitch | Often $8,000 to $14,000 | Layers to remove, deck repairs, eave protection |
| Mid-size two-storey, a few valleys | Often $12,000 to $22,000 | Height, valleys, flashing at walls and chimneys |
| Larger or steep, cut-up roof with dormers | Often $20,000 to $35,000 or more | Pitch, safety setup, complexity, skylights |
| Upgrade from Oakridge to Duration on the same roof | Often a few hundred to a couple of thousand dollars more | Roof size, supplier pricing |
| Deck board or sheathing replacement | Often priced per sheet as found | Condition revealed after tear-off |
When comparing quotes, line them up item by item. A quote that looks cheaper may leave out ice and water barrier on the eaves, new drip edge, flashing replacement or ventilation, and those omissions matter more to the roof’s life than the shingle brand.
Questions To Ask Your Contractor
- Which exact shingle line and colour are you quoting, and is it in stock locally?
- Will you use four or six nails per shingle, and starter shingles at both eaves and rakes?
- Which underlayment and eave protection are included, and how far up the roof does the membrane run?
- Is all flashing new, or will any be reused?
- How is deck replacement priced if rot is found?
- How will you balance attic intake and exhaust ventilation?
- Which manufacturer warranty applies, and what workmanship coverage do you provide in writing?
Seeing a real sample against your own brick settles most colour debates, so ask for Oakridge and Duration samples at the estimate; our Halton Region roofing, eavestroughs and attic work team can bring them so you can check them in daylight.
