Cedar shingles are a favorite material for roofs and walls because of their wide availability and ability to stay strong for many years. However, even cedar begins to break down after awhile, thanks to the loss of naturally occurring oils that protect the structure of the wood. Sunlight and moisture are the main culprits when it comes to cedar decay; organic debris, which encourages the growth of mold and mildew, can also lead to a decline in shingle quality. These steps show you how to protect cedar shingles through regular maintenance and, when necessary, how to treat the shingles for greater protection.
1. Regularly clear debris off of the cedar shingles.
Organic matter like branches and leaves that lie on cedar for a long time can grow mold and mildew, which will in turn seep in the cedar and cause its quality to deteriorate. Clear the shingles approximately every 2 weeks, and remember to remove any debris after rainstorms.
2. Clear ice off of the cedar shingles
3. Keep inside areas behind the cedar shingles properly insulated.
Moisture from inside a building can also damage cedar. Places to keep an eye on include attics and structures that hold water.
4. Remove moldy or rotten cedar shingles
