How to Maintain Cedar Shingles

It doesn’t seem to matter if it’s Eastern White or Western Red, cedar siding makes a home stand out. As a siding material for homes in the lower mainland, cedar shingles are durable, possess excellent insulative properties, and are insect resistant. If properly maintained, cedar siding has a lifespan of 25 years or more. Use these tips to keep your cedar siding looking beautiful throughout the years.

Periodically Inspect Siding

Scratches can snag organic matter and trap it on the surface of the cedar shingles where it can grow mould and mildew. Cracks in cedar siding shakes and shingles allow moisture in that can rot the wood, invite insect infestation, and/or create an environment for mould and mildew.

Check relevant flashing and caulking for cracks and holes. Cracked flashings and holes in caulking can let water into places not easily reached by sun or air.

Scratched, cracked, or damaged wood needs to be sealed with the appropriate sealant.

Clean Siding Regularly

Cleaning cedar siding regularly is important. When dirt, dust, and grime are allowed to accumulate on cedar shingles or cedar shakes, they can harm the finish of the siding, making it vulnerable to water damage, including mould growth.

Proper Insulation

High humidity inside a home can affect the exterior walls, subjecting them to excess moisture, which in turn can cause damage to the cedar siding. Ensure that interior walls are adequately insulated. Another option is to control the amount of humidity inside the house, reducing it to 40% or less.

Painting or Staining

For some homeowners, the appeal of cedar siding, when the wood is untreated, is the silver-grey patina it develops over time. Untreated cedar siding is more labour-intensive to maintain, so it is often sealed or painted to help protect it from the elements. Painted or stained cedar siding needs to be redone every few years to help it keep protecting your home.

Replacing Shingles

Replace moldy or rotted shingles as soon as they have been discovered. This will contain the problem and prevent mould or rot from spreading to other areas of the siding.
