Cedar roofs are stunning, but they require expert care. Cracked, split, and missing shakes need specialized repair to maintain both protection and appearance. Trust Burnham Brothers' 35 years of cedar roof expertise.
Cedar roofs are beautiful. There's nothing else quite like them. But that beauty comes at a cost: cedar is a natural material that needs attention.
Here's what homeowners often don't realize: those stunning cedar shakes are also doing the hard work of keeping water out of your home. The moment they crack or split, water starts getting in.
What happens:
Plus the aesthetic loss: A beautiful cedar roof with damage starts looking neglected and loses its curb appeal fast.
In Ottawa, this happens even faster:
The good news: Cedar roofs can last 40-60+ years if maintained. Small repairs done right can keep your roof beautiful and protective for decades.

Cedar roofs have unique challenges. We inspect which shakes are cracked, split, or missing; the condition of underlying shakes and deck; any signs of rot or decay in the roof structure; flashing condition and potential water entry points; overall roof age and remaining lifespan; and attic ventilation and moisture conditions.
Unlike asphalt shingles, not all cedar shake problems require replacement. Sometimes a crack just needs sealing. Sometimes a shake is failing and needs removal. We assess each damaged shake individually.
Your estimate specifies which shakes will be removed and replaced; which shakes might be sealed or stabilized; whether underlying deck repair is needed; material sourcing (we match your original shakes' size and grade); labor involved; timeline; and any flashing repairs or additional work.
If a shake needs replacement, we carefully remove the old shake without damaging neighboring shakes or the underlying deck. Careless removal can cause additional damage that costs thousands. Once a shake is removed, we inspect the underlying roof deck. If we find rot or decay, we address it. A solid deck is essential for the new shake's longevity.
We install new cedar shakes that match your original shakes (or are as close as possible), are properly fastened with stainless or hot-dipped galvanized nails, are installed to allow for expansion/contraction, overlap correctly with neighbors, and are sealed with products appropriate for cedar.
All roof penetrations get sealed properly. Flashing is where most cedar roof leaks occur. We inspect every repair, ensure drainage is correct, and clean up completely. <strong>Timeline: Cedar shake repairs typically take 1-3 days depending on the number of shakes involved.</strong>
One challenge with cedar roof repair: finding replacement shakes that match your original.
We can often source exact matches or very close replacements from the original manufacturer or standard suppliers.
Cedar shake specifications have changed over decades. We may not find exact matches, but we find the closest possible replacement. New shakes will weather to match over 12-18 months.
Some cedar roofs use hand-split or premium shakes. We source these from specialty suppliers to maintain your roof's character.
We consider shake length (usually 16", 18", or 24"), shake thickness, grade and quality of cedar, and whether shakes are machine-split or hand-split.
We'll source the best match possible for your roof. If exact matching isn't available, we'll explain the options and costs.
Cedar expands and contracts with temperature and moisture. Ottawa's 50+ freeze-thaw cycles per winter create extreme stress. Water gets into shakes, freezes, expands, and splits the wood. This is the primary cause of cedar shake failure in our climate.
October/November wet snow and spring melt create heavy loads on aging cedar roofs. This stress can cause shakes to shift, fasteners to loosen, and splits to widen.
Summer sun hardens cedar and causes checking (surface checking, not deep cracks). Winter moisture works into these checks and splits them. The combination is brutal.
Salt spray from winter roads corrodes fasteners and breaks down cedar's natural oils. This accelerates decay and fastener failure.
Your cedar roof in Ottawa experiences more stress than cedar roofs in milder climates. This doesn't mean cedar isn't worth it—it means regular inspections are essential (every 2-3 years recommended), small problems should be fixed promptly, good attic ventilation reduces moisture damage, and strategic maintenance extends the roof's life significantly.
We repair cedar roofs with Ottawa's climate challenges in mind. We use proper fastening, we ensure good ventilation, and we recommend regular inspections to catch problems early.
We've repaired hundreds of cedar roofs in Ottawa. We understand cedar's behavior in our climate.
Cedar roofs require different techniques than asphalt or metal. Our crews train specifically on cedar repair.
We understand that cedar roof damage isn't just a functional issue—it affects the beauty of your home. We repair with care and attention to aesthetics.
We work with suppliers who can provide matching cedar shakes, even for older roofs.
We repair cedar roofs knowing freeze-thaw challenges, ventilation needs, and moisture problems unique to our region.
If your roof can be repaired, we say so. We don't recommend replacement for profit.
Full liability and WSIB compliance. You're protected.
We use proper fasteners (stainless or hot-dipped galvanized) and sealants rated for cedar and our climate.
