Roofing Is The Essential Part Of House BuildingRoofing is the most vital part of a building. The covering protects it from the ravages of the weather. It has various other functions. Besides providing support to the entire structure, the controlled flow of air, heat, ingress of water and the vaporization of water, is all because of the roof. This shelter above the head has to have proper material and assembly in order to make it long lasting. The roof cost depends on the material used, strength and the type of construction. The roofing of a house can be done using different materials. The roof that is thatched is covered with leaves from plants especially wheat hay. For homes built near the sea, the roof is generally covered with sea weeds. They are both cheap and are known to last more than sixty years. Synthetic sheets of rubber pasted together form good roofing material too. The red colored cedar, hardwood, concrete and ceramic tiles, that last for a hundred years, are the other common materials used. The shingle is another form of roofing with any material having overlapping sections. Wood shingles are more well known. However shingles made of asphalt are very much in demand these days because of their low price and easy installation. An asphalt shingle is composed of bitumen inserted in a mat made of fiber glass. The two types of asphalt roofing are fiber glass and organic. The organic variety is usually made of felt paper soaked in asphalt, coated with adhesive and then powdered with small granules of ceramic. These are extremely durable lasting up to 50 years. The fiber glass shingle is made of a mat which is covered with asphalt, making it water proof. These are a replacement for asbestos roofs which tend to fly off during storms. The latest form is the laminated asphalt shingle made after pasting two layers of shingles. They are much stronger, have more weight and are slightly expensive. The durability of the asphalt shingle depends on the climate. In hot places, these do not last long because the atmospheric heat makes the asphalt layers soft-top seal may become loose. The cold weather is not conducive to shingles that are being freshly applied. This is because the cold will not allow the layers to paste with each other properly. For the roofing to be long lasting, instead of staples the nails are better. Other than asphalt, metal shingles are also used. Roofing can also be done by oneself, nowadays. The DIY roofing, following instructions from ace constructors is very much in vogue. There are consultant firms providing easy- to- follow videos. There are several points to be remembered for DIY roofing. Proper ventilation, nail leveling and protection of the felt must be taken care of. |
