Roof Types

Most residential roofs consist of six materials:

Asphalt Shingles - the most common material being used for roofing, also known as "composition shingles", and is compatible with warm and cold climate. Asphalt shingles are very durable, and the heavier the shingles are, the more durable they become (life expectancy is 15-30 years). Manufactured in a variety of colours. Note, that heavier shingles will probably mean higher installation cost.

Fibreglass Shingles - very common, and highly durable. Again, as with asphalt, heavier shingles will be more durable. Fibreglass shingles are considered highly resistant to fire, and are widespread due to the successful combination of price, looks, and durability.

Wood Shakes and Shingles - The term shingles refers to sawn wood, The term shakes refers to wood that has been split. Shakes are thicker and has a more rough look. The cost of materials and installation of the wood roofing my get up to four to five times of that of asphalt or fibreglass one. Notice that the material is considered highly flammable. Although It is well resistant to the weather, it will usually be the choice of style, due to its textures, and the contribution it makes to certain house styles.

Slate Shingles - are very durable and expensive. Slate shingles are heavy as they are stone and require a structurally reinforced roof frame to support the the weight of the materials. This increases the cost of this type of roof. Slate shingles are available in many textures and make a highly desirable and beautiful roof that with proper maintenance will last a considerable number of years.

Tile Shingles - are made of clay or cement, and available in many colours and textures, these tiles are very heavy and require a very strongly framed roof to carry the weight. The roof will be highly durable and will last for a very long time. This type of roof is very common in warm climate areas and are expensive to install due to the materials used and the structure needed to support them.

Metal Shingles - are usually made of alloy or a tin/lead alloy, these shingles are very light in weight and very durable. They will last a long time if fastened well with aluminum nails. This type of roof covering is considered relatively expensive and due to the materials used may be noisy during rainfalls, or other heavy precipitation. Metal shingles are available in many colours, shades and styles.
