There are lots of options in roofing market where you can get the best roofing materials for the overall protection of your home. Some common roofing materials are asphalt shingles, fiber-cement, metal, modified bitumens, slate, tile, polyurethane foam and many more.
Asphalt shingles are widely used roofing materials as it is quite inexpensive in comparison to other materials. Durability and availability in various colors and textures make it first choice among homeowners.
If you are in area where fungus growth threatens the roofing material, then algaecide treated asphalt shingles are best solution. Another remarkable feature of shingle is self sealing. There is adhesive on the underside of the shingle which reacts with sun light after installation and seals with other shingle below it. Such shingles well resist wind.
Shingles come with varying thickness size at present. They are known as dimensional or architectural shingles.
Fiber-cement roofing materials:
As its name, this roofing material comprises of cement and organic or inorganic fibers. It is lighter and can resist fire at high degree.
Generally, metal roofing material is installed in such area or region where precipitation is high. It has three distinct qualities—lightweight, durable and fire resistant. Architectural metal roofing, on the other hand, serves best as shed. Both of these roofing materials—metal roofing and architectural metal roofing—are available in different varieties such as standing seam metal roof panel and die-formed panel.
Polymer modified bitumens or modified bitumens were introduced in the US in mid 1970. The materials come in rolls and bitumens are treated with plastic or rubber at the time of manufacturing. This roofing material resists ultraviolet radiation.
Slate is nonabsorbent natural material. It comes in varieties of colors. Slate that fades after sometime of exposure is known as weathering slates whereas minimal fading one is termed as permanent slate.
In comparison to other roofing materials, slate is expensive. Moreover, its installing cost is high and seeks well skilled manpower for installation. It is heavy material so roof structure should be strong enough to hold its weight.
Clay or cement tile is regarded as substitution of slate as it comes with different styles, color and is less expensive in comparison to slate. It last longer and is fire resistant. Tile also requires roof reinforcement as the material is heavy like slate.
The world witnessed this roofing material somewhere around 40 years back. The insulating features of sprayed polyurethane foam took its popularity to new height. Two components—isocyanate and polyol—are combined together and sprayed on the surface in liquid form. The material expands upto 30 folds of its original volume after application. Later, it sets as solid material forming skin on the surface. This skin resists water whereas solid material or foam gives insulation. The final coating on the surface protects foam from ultraviolet radiation.
