As with any other roofs, cedar shake roofs may develop cracks and leaks with time. Fortunately, there are ways to give your cedar shake roof a complete overhaul.
Here are the answers to two frequently asked questions about this type of roof.
What cause lifting, curling, and cupping of shingles?
Lifting, curling, and cupping of a cedar shake roof are often caused by improper installation and use of low quality roofing materials.
Improper roof ventilation – Lack of roof ventilation or no ventilation at all may cause lifting, curling, and cupping of the shingles. Without proper ventilation, your cedar shake roof will not get the necessary air flow to last for years. Ideally, the temperature of the cathedral ceiling cavity should be same as the outdoor temperature. For instance, if outdoor temperature is 100 degrees, the temperature of the cathedral ceiling cavity or attic should be between 95 and 105 degrees. The different between outside and inside temperatures should not be more than 10 to 15 degrees. The indoor air flows through the attic floor insulation to the attic space. If the indoor temperature varies a lot from the outdoor temperature, it may create condensation on the roof deck, which may lead to mold growth.
How can I tell whether my cedar shake roof needs repair or complete replacement?
It depends on a number of factors. A roofing expert will be able to give you the best advice after a thorough roof inspection. In general, if you notice some fundamental material deficiencies, you may need to replace your roof completely. Some telltale signs that your cedar shake roof might require replacement are as follows:
- Ice dams leaking into your home
- Constant lifting, curling, and cupping of the shingles
- Consistent fallout of shingles from most parts of the roof (This often leads to lifting, curling, and cupping of the cedar shake and lack of ventilation.)
- Shingles throughout the roof developing cracks, fractures, and splits
- Rusty or decayed nail heads or shafts
- Light passing through openings and small gaps in the shingles through the attic
- Stains or dark spots on the wood shingles visible from inside the attic, especially when it is raining outside
- Shingles are lifting days after they are installed (This is also known as cell collapse and mainly occurs during the summer months. This problem is common with domestic quality cedar.)
- Shingles crafted out of low quality cedar –Substandard cedar shakes manufactured may not be enough to provide you rock solid roofing.
