From the perspective of cost performance, which type of material is the best?

The biggest drawback to tile can be its heavy weight. The roof truss built with it is easy to suffer from deformation. Moss easily grows on it. It needs to be frequently cleaned since leakage would be a hidden problem.

A wood shake roof usually costs more. Small animals can also be a problem to it. A short service life is another drawback.

The main disadvantages to metal roofing are the sound proof problem and poor heat shielding performance, which results in much heat in summer and high rate of heat loss in winter.

From the perspective of cost performance, we recommend that asphalt shingles are the best option.

 

Why asphalt roof shingles are the most popular choice for roofing material?

A. Asphalt roof shingles are characterized by their long service life, light weight, safety and aesthetic appearance.

B. All asphalt roof shingles are guaranteed for 25 to 30 years of service life by manufacturers. (Partly under certain conditions)

C. Asphalt roof shingles are light-weighted, so that they may not produce much pressure on the roof structure.

D. Asphalt roof shingles can minimize casualties during an earthquake.

E. Asphalt roof shingles of higher quality versions can create a strong dimensional effect.

F. Asphalt roof shingles may contain a portion of copper or tin materials to discourage moss growth on the roof.

 

Why composition shingles are the most popular choice for roofing material?

A. Composition shingles are characterized by their longer service life, lighter weight, safety and aesthetic appearance.

B. Compared with other roofing materials, composition shingles require lower maintenance cost yet own higher strength.

C. Compared with asphalt roof shingles of the same size, composition shingles are lighter.

D. Composition shingles can minimize the injury to the human body in case an earthquake occurs.

E. Of all roofing materials, composition shingles creates the strongest dimensional effect.

F. Composition shingles can be cleaned with high strength cleaning equipments (high pressure water cleaner, for example).

How to care and maintain the wood shake and shingle roof?

 According to some professionals of Ontario Roofing Association, wood shake and shingle roofing had better be cleaned with broom and normal water pipe. High pressure water cleaner is not applicable. Repainting should also be avoided. High pressure water cleaner and repainting can only maintain the appearance of roof for a short period of time, typically one to two years. After that, wood shakes may continue to become darker and cracks may appear.
