Cedar Shake Roofing in Airdrie

The appeal of cedar, and the Airdrie reality

A cedar shake roof has depth and texture that no manufactured product quite matches. The shakes are split or sawn from western red cedar, and over time they weather from warm honey-brown to a soft silver-grey. On a craftsman-style home — the kind of architecture you see across Reunion and on the larger lots of Hillcrest, with stone bases, tapered porch columns, deep gables and covered front porches — cedar can look exactly right.

In practice, most craftsman homes in those communities were delivered with dimensional asphalt shingles, not wood. So the cedar conversation we have in Reunion and Hillcrest usually isn’t “repair my shakes” — it’s “can I put a cedar or cedar-look roof on this house when the builder roof comes due?” Before anything else, check your community’s architectural guidelines and your homeowner association, if you have one: some streets specify roof colour and profile, and a change in material can need sign-off.

Cedar is also the most demanding roof you can choose in Airdrie. The city sits in Alberta’s hail corridor, the air is dry for much of the year, the sun is strong, and the northwest wind blows across open prairie. Every one of those works against a wood roof. None of them makes cedar impossible, but they all change what it costs to own.

That’s why we start every cedar conversation with the honest picture, not a brochure.

Cedar shakes vs. cedar shingles

The two terms get used interchangeably, but they’re different products:

Cedar shakes are thicker and more rugged, traditionally split rather than sawn, with a rough, textured face. They cast deep shadow lines and give the rustic look most people picture.

Cedar shingles are thinner and sawn on both sides, with a smoother, more tailored appearance.

Shakes are thicker, which helps them handle weather and impact better than thin shingles, and they’re what most homeowners mean when they ask for a cedar roof.

What Airdrie’s climate does to cedar

Hail. Cedar has no impact rating. Large hail can split shakes and strip their weathered surface, and older, dried-out shakes split more easily. Thicker, higher-grade shakes stand up better, but in a hail-prone city this is the biggest trade-off.

Dry air and strong sun. Cedar is a natural material that expands and contracts with moisture. In Alberta’s dry climate, with its strong UV, untreated shakes dry out, cup, crack and split sooner than they would in a damp coastal climate.

Wind. Loose or split shakes lift in strong gusts. Correct fastening, and replacing damaged shakes promptly, matter on exposed lots.

Freeze-thaw. Moisture that gets into cracks freezes and widens them, especially during chinook cycles.

Snow and ice. Cedar needs the same ice-and-water protection at the eaves and valleys as any other roof, because ice dams will push water under it just as they do under shingles.

Installing cedar properly

A cedar roof lasts only as long as its installation allows. The details that matter most:

• Breathing room. Cedar needs air to dry from both sides. Depending on the system, that means spaced sheathing or a ventilation mat under the shakes, so moisture doesn’t stay trapped against the wood.
• Interlayment. Shake roofs use an interlayment between courses to shed any water that gets past the shakes.
• Ice-and-water shield at the eaves and in valleys, as on any Airdrie roof.
• Corrosion-resistant fasteners. Cedar contains natural oils that corrode ordinary nails; stainless steel or hot-dipped galvanized fasteners are standard.
• Correct exposure and spacing. Shakes are laid with gaps between them to allow for swelling, and with the right amount exposed for the roof’s pitch.
• Proper flashing at valleys, walls and chimneys — see chimney flashing repair for the details that fail most often.
• Attic ventilation balanced so heat and moisture escape.

Cedar suits steeper roofs, where water runs off quickly. On a low slope it holds moisture and wears faster.

Maintaining a cedar roof in Airdrie

Cedar isn’t a roof you install and forget. To get a full life from it here:

• Keep it clean. Needles, leaves and debris hold moisture against the wood. Clear valleys and the areas behind chimneys.
• Trim overhanging branches — especially on treed lots in Old Town — so the roof gets sun and air and isn’t scraped in the wind.
• Replace split and missing shakes promptly, before water gets under them.
• Consider periodic treatment with a product made for cedar roofs to slow drying and weathering.
• Inspect after hail and windstorms. Split shakes are easier to see up close than from the ground. See roof inspection.

When an existing cedar roof is tired but structurally sound, cleaning, treatment and selective shake replacement can extend its life. See roof restoration.

Repairing an existing cedar roof

Many cedar roofs in and around Airdrie — on older homes and on acreages outside the city — are worth repairing rather than replacing. The usual work:

• Replacing split, cupped or missing shakes with new shakes of a matching grade and thickness, slid into place and fastened so they don’t block the course above
• Re-flashing valleys, walls and chimneys where the metal has worn or was never right
• Rebuilding hips and ridges, which take the most wind and weather
• Clearing debris that holds moisture against the wood

New shakes start out a warm honey colour and weather to match the rest of the roof over time. If more than a modest share of the roof is split or rotting, or the shakes crumble when you handle them, the roof has reached the point where repair money is better spent on replacement — with cedar again, or with one of the alternatives below.

Cedar alternatives worth pricing

If you love the look but not the maintenance, fire and hail trade-offs, these give a shake-style roof with better performance:

Steel shakes. Pressed steel formed and finished to look like wood shakes, often with a textured coating. Long-lived, non-combustible, and they handle wind well. See metal roofing.

Synthetic (composite) shakes. Moulded to look like cedar, with impact and fire ratings depending on the product.

Shake-style Class 4 asphalt shingles. Thick dimensional shingles designed to imitate shakes, with the top impact rating and a much lower price. See Class 4 impact-resistant shingles.

What cedar shake roofing costs in Airdrie

Grade and thickness of the shakes, fire-retardant treatment, what’s needed underneath and the roof’s complexity all move cedar’s price. For every factor, see the Airdrie roofing cost guide; if you’re pricing a shake-look steel alternative, the metal roof cost guide covers stone-coated steel.

Is cedar right for your home?

Cedar makes the most sense when the architecture calls for it, the roof is reasonably steep, you’re prepared for regular maintenance, and your insurer and the City of Airdrie are comfortable with the product you choose — including its fire treatment. If one of those isn’t true, a shake-look alternative will usually serve you better in Airdrie’s weather. We’ll help you decide — and if cedar isn’t the right call for your house, we’ll say so.
