Problems with Cedar Wood Shake Roofs

Hand-split wood shakes have been used to roof American homes for centuries. Most popular today is the cedar shake shingles. They are widely chosen for their character, charm, and beauty. But there is a problem with using natural wood, especially in the Madison and Milwaukee, Wisconsin areas… as a roofing solution, it has undeniable drawbacks.

High Maintenance

Wood shingles generally are high maintenance especially in Southern Wisconsin. Wood cedar shingles require regular cleaning. The wood material captures excess moisture that leads to rot, mold and mildew, if not removed reularly it dramaticly shortens the life of the roof. Cedar shake roofs need protective treatments every few years.

Insect Damage

Without regular protective treatments, these pests can wreak havoc on your cedar shake shingles, undermining its structural integrity.

Curling, Cupping and Split Shingles

After years of exposure to the sun, rain and wind your wood shake roof will begin the process of curling, cupping and splitting. Curling is when the shingle starts to develop lifted edges, so it’s no longer lying flat against the roof. Cupping is when the shingle becomes concave, forming a cup shape that eventually causes them to splinter. Wood shingles tend to break during heavy hail, rain, or windstorms. Broken shingles may fall off leaving your home exposed to the elements and may cause costly water damage.

Low Fire Resistance

Wood is flammable, which makes cedar shake roofing a fire hazard. Cedar shakes have a low fire resistance insurance rating, which is a significant concern for homeowners in fire-prone areas. While fire-retardant treatments can improve their safety, these treatments require regular reapplication and are not foolproof.

High Costs

Cedar shake roofing is one of the most expensive roofing materials available. The material cost is high and professional level installation is required making it a very expensive roof to add to your home.
