Step 1
Slate and clay tile roofing materials, the most expensive roofing materials, are very heavy and will require a stronger roof structure to support them.
These materials are both predrilled for nailing to the roof surface and are laid in overlapping rows.
Both slate and clay tile roofs are extremely durable, and properly maintained will last more than the average lifetime. -
Step 2
Metal roofing has become increasingly popular largely because of its durability and fir-resistant nature.
Metal roofing comes in corrugated patterns for added strength and drainage.
Metals may be aluminum, galvanized steel, copper or an alloy.
Because the surface of metal is so smooth it is especially suited to areas of heavy snowfall. -
Step 3
Shakes and wood shingle roofing is now treated with preservatives and often pressure-treated to reduce a potential fire hazard.
Because of the fire potential, this roofing is not allowed near some forested areas.
Shakes are thicker and have a more textured surface than do machine cut wood shingles.
Both material can last upwards of 35 years, if properly maintained. -
Step 4
Asphalt shingles are the most economical and versatile of residential roofing materials. They are fire resistant.
Better quality shingles are treated to reflect sunlight that is damaging to the asphalt.
Shingles often have a sealant which reacts to heat and seals the overlapping shingles to prevent lifting.
Asphalt shingles come in many colors and grades so purchase the best you can afford. These should last upwards of 30 years. -
Step 5
There are synthetic roofing materials available which come in sheets which are cemented or heat-fused together.
These materials are ideal for flat roofs but are very expensive and generally used only on commercial buildings. -
Step 6
Whatever roofing material you choose, maintain it well and you will extend its life.
Always check the building codes in your area to see what materials are allowed and recommended.
