Today I will talk to you about the advantages, disadvantages and costs of the five most common roofing materials in North America.
Asphalt shingles
Because of its low cost and easy installation, more than 75% of North Americans choose asphalt shingles as roofing materials. At the same time, it is also the most common roofing material in the United States.
Advantages – There are many colors to choose from, various shapes, and a wide range of applications. The roof is light-weight and easy to construct, making it the cheapest roofing material.
Disadvantages – Compared with other materials, asphalt shingles have poor thermal insulation performance, are prone to aging, and have a short service life. At the same time, they have poor flame retardancy. Although the initial cost is low, replacing the roof every 20 years or so will increase the cost of use.
Service life – 15-30 years
Price – $1.5 – $5.5/sqft
Slate
The natural look of slate allows it to be used in a variety of roofing and architectural styles. As the most durable roofing material, slate has excellent resistance to weathering and fire. And it is easy to maintain a good appearance over a long period of use. Basically, the century-old mansions in Massachusetts are made of this material!
Advantages – As a natural material, slate is more environmentally friendly and energy-saving. Its durability and easy maintenance make it possible to increase the value of the house when it is resold, and it basically only requires daily maintenance to replace the damaged ones, without the need to replace the roof on a large scale.
Disadvantages – Slate roofs require additional reinforcement and professional installation to withstand their weight. There is a large loss in material transportation and construction. The material is brittle, people cannot step on it hard, and it will be more troublesome to repair it.
Lifespan – 80-100 years
Price – $20 – $40/sqft
Metal
