The Weight Limits of a Cedar Shake Roof

Sheer

• Cedar shingles are secured with nails, as are asphalt roofing shingles. They can resist sheer forces better than asphalt shingles can, as they are generally thicker. Homeowners should not be concerned about the sheering hazard of cedar shingles more than asphalt shingles. Compared to Spanish tile, cedar shingles are lighter and more easily secured, meaning they are more resistant to sheering. Be careful, though, when walking on any roof, as a rotted shingle could fall apart and become a slipping hazard.

Pressure

• Cedar shingles spread pressure across the wood underneath. The surface they create is as strong as that wood. Even if a cedar shingle rots, weight applied to it will be born by the real strength of the roof. That said, it should be troubling if a cedar shake roof is rotting, as that implies the roof underneath is getting damaged.

Cedar Overall

• Cedar wood naturally resists pests and has oils that make it water-resistant. Cedar's light weight makes it a good choice for cold climates, where the added weight of snow can put stress on the frame of the house. It is an eco-friendly roofing choice, as fewer harsh chemicals are used in creating cedar shingles. It is a rather expensive choice, though, since cedar is a natural wood, rather than a man-made substance.

Other Roofing Materials

• When deciding what roofing material is best, strength and weight-bearing potential are more important for those who will need to walk on that surface regularly or expect heavy snow. This is mostly true in colder climates, and cedar is a good choice. Those in warmer climates should consider tile, as it is better at reflecting heat.
