A cedar roof does not provide waterproofing, despite what many homeowners may think. There is tar paper below your cedar roof which is designed to prevent water from leaking into your roof space. With that said, there are signs to look out for that will tell you when your cedar roof needs repairs.
You can expect most cedar shingle style roofs to last around 20 years. That is without maintenance and barring any major damage caused by storms. Medium hand-split cedar roofs, on the other hand, may last as long as 25 years. Homeowners with a heavy hand-split style will be happy to know that they made a sound investment, as these roofs can achieve a lifespan of 30 years or more. That is not to say you should never have your roof checked. There are plenty of mishaps that can reduce the lifespan of a cedar roof.
Leaks & Moisture Damage
As already mentioned, it is not the cedar roof structure that protects your home from moisture intrusion. However, if the tar paper underneath is allowing water to leak into the roof space, it is still an issue that warrants repair. Water damage can wreak serious havoc on internal and external structures, as well as providing a breeding ground for mold that poses potential health hazards.
Warping & Distortion
When areas of a cedar roof are visibly warped or distorted in any way, it is a sign that repairs are needed to save the roof. If you do not address the issue, it may reach the stage where maintenance is no longer an option, which means a costly roof replacement. These problems may be a result of poor installation or nature taking its course when UV light, rain, and other environmental factors contribute to the roof aging prematurely.
There are microorganisms such as algae and mold that love moist environments and an organic food source. Your cedar roof is essentially a large and exposed buffet for these hungry invaders. If mold and algae are left unchecked, your roof will begin to soften and the material will break down. Without cleanup and repair, you will end up dealing with a roof replacement that could have otherwise been avoided.
