How to Repair a Cedar Roof
A cedar roof is a functional-cum-aesthetic roofing choice. Cedar roofing is preferred by homeowners who want to establish a classical style without compromising on the overall durability of the roof. Most cedar-roof repairs involve repairing the smaller, roofing parts. A conventional cedar roof is made up of roofing ingredients like shingles and shakes. Every shake is essentially a precut, tile-like roofing patch. Repairing cedar roofs is easy, and some common cedar-roofing problems and undemanding repairing methods are listed below.
Cedar Roof Problem 1—Moss Growth
Cedar shingles often develop deposits of moss. The problem becomes more severe if the roofs aren’t cleaned regularly. Moss compromises the durability and aesthetics of a cedar roof. For starters, moss retains moisture. The moisture seeps within the roof, often leading to roof-leaks and damp patches along the inner walls. Further, the moss layering spoils the appearance of a roof. A moss-covered roof develops a dilapidated appearance.
Solution—Removing & Securing against Moss Growth
There are no easy ways of removing the moss. You need to climb on top of the roof and scrape off the moss. You can use any sharp object for scrubbing the moss. A metallic scraper or a metal brush is recommended. After removing the moss, cover the scraped area with metallic strips. Use nails and a hammer to secure the metallic strips. You can buy weather-solution metal strips that don’t rust and offer years of maintenance-free performance. Metal strips also help to strengthen aged cedar roofs. The strip induces a chemical reaction along the roof’s surface that neutralizes any moss growth. However, this is not recommended if the roof contains treated shingles. Treated shingles are pre-treated with a special solution to negate moisture growth. Hence, if your have treated shingles and they show signs of moss growth, contact the retailer for re-treatment of the shingles or a warranty-backed replacement. After installing the metal strips, spray the entire roof with a fungicidal solution. You can use a plastic sprayer for this. Dilute the fungicidal solution according to packaged instructions. Now, spray the roof with a roofing preservative solution. These chemicals impede moss growth and ensure that the inner lining of the metal strips are attacked by fungal growth.
Cedar Roof Problem 2—Misplaced Shakes
Most cedar roofs consist of rectangular shakes that are installed in an overlapping or sideways manner. The shakes are often displaced due to rough weather conditions. Wobbly shakes allow moisture seepage, making the shingles vulnerable to corrosion.
Identify shakes that can be repaired. Slightly curled shakes are easily repairable. However, if the shakes are bent or have a hard-to-repair curvature, you should replace them. Using a pry bar, loosen the damaged shake. Remove the nails and pull-out the shake. Using a hammer, try to re-shape its borders. However, if the damage is too severe and the shake’s core too has considerable damage, replace it. Replacement shakes are easily available at hardware supply stores. A new shake is easy-to-install. This can be easily done with a hammer and some nails. When installing a new shake, don’t hammer it upon the nearby shakes. Try to slide it along the designated spot and hammer minimally. If the replacement shake is a bit bigger than the repair spot, you can bend its corners with a hammer.
