If you are considering a cedar shake roof for your home, you may be wondering how long you can expect it to last before necessary repairs or replacements. This is a complicated question, as the life expectancy of any part of your home will vary greatly depending on the quality of the original installation, the climate and weather and the maintenance that you regularly perform on the roof. Below you will find a general idea of how long your cedar shake roof will last, along with basic tips on how to lengthen its useful life.
Average Length of Time
In most homes, the average life expectancy of a cedar shake roof will be somewhere in the neighborhood of 30 to 40 years. This can be slightly longer than asphalt shingles, but this will vary based on factors such as climate and the presence of overhanging trees.
To lengthen the useful life of your cedar shake roof, you can treat the wood with a penetrating wood preservative every 5 years or so. This will make the wood more resistant to rotting, mildew and mold. You should also try to keep your roof as free from dirt, leaves and other debris as possible.
