What maintenance is recommended for exterior CEDAR or REDWOOD?
We see a lot of modern architecture that incorporates cedar or redwood siding/decking and cedar roofing. Not only are these woods beautiful, they are durable as well. A lot of modern cedar shake roofing is applied over water & ice barrier and the shakes are mainly decorative. Some cedar roofing is factory treated, while most is not. For the best life expectancy, shake roofing should be cleaned and treated with a sealer or sealer/stain about every 5 years. The cleaning process for cedar and redwood is similar to other woods, but must be handled very carefully. Even more so on shake roofing.
