Cedar roofs are known for their natural beauty, insulation properties, and long lifespan—but like any roofing material, they require care and maintenance to perform their best. In Toronto’s damp winters and hot summers, cedar shingles and shakes are exposed to intense weather conditions that can lead to wear over time. If you have a cedar roof, recognizing the signs of needed repair can help prevent costly damage and preserve your roof for decades to come.
One of the most obvious signs is cupping or curling of the cedar shingles. This happens when the wood begins to dry unevenly, usually due to age, sun exposure, or poor ventilation. When shingles start to curl, they allow water to seep underneath, which leads to leaks and potential mold growth. If caught early, these shingles can be replaced individually before the problem spreads.
Another red flag is splitting or cracking. Cedar expands and contracts with temperature changes, and over time, that movement can cause the wood to split. While small cracks are normal, large or deep splits often signal that the shingle has become brittle and is no longer protecting your roof properly. These areas are vulnerable to water damage, especially during freeze-thaw cycles in Toronto’s winter months.
You should also look for moss or algae growth, particularly in shaded areas. Excessive moss traps moisture against the surface of the roof, accelerating decay. If you notice green patches or a musty smell in your attic, your cedar roof may already be retaining moisture and should be inspected right away.
At Roof Repair Toronto, we offer expert cedar roof repair tailored to the specific needs of these premium roofs. Whether you’re dealing with isolated shingle damage or larger sections that need replacement, we assess the condition of your roof and make recommendations that balance appearance, function, and longevity.
We also help homeowners understand when a cedar roof can be repaired versus when a full replacement may be necessary. Most cedar roofs can last 30 to 50 years, but regular maintenance plays a big role in achieving that lifespan. That’s why we also recommend routine inspections and cleaning as part of a comprehensive care plan. You can always reach out to Roof Repair Toronto for a personalized roof evaluation.
In conclusion, cedar roofs require unique attention, and knowing the signs of wear can help you act before damage spreads. Whether it’s curling, cracking, or moss buildup, early detection leads to simpler repairs and a longer-lasting roof.
