Basic Components That Comprise the Roofing System

A homeowner must always have a good idea about every aspect of his house, at least having a better understanding about the basics, as the knowledge gained can be helpful during discussions with contractors when it comes to major repairs or additional improvements in the home.

A knowledgeable homeowner on the basic parts of a home will see to it that the right kind of home materials should be considered for his home to be in good condition, such as for example when it comes to the roofing system, having an idea about the basics will certainly allow him to choose the right roof materials for his home. The roof structure is made up of three basic components – underlayment, flashing, and shingles or tiles.

Roofing underlayment is a material that is first installed directly onto the roof deck as an added material protection from the coarse weather condition and because of this reason, most underlayment materials are water-resistant. Most common roof underlayment are made up of any of these main types, but are basically composed of asphalt, these are: the felt paper asphalt underlayment, which is basically made up of asphalt, cellulose, and polyester; the synthetic underlayment which is a combination of the asphalt underlayment with fibreglass to make the material stable and resistant from the wear and tear; and the rubberized underlayment, which is still made up of asphalt and with combination of rubber polymer and with a special design that has a sticky, protective back membrane that functions as a waterproof sealant between the roof deck and the underlayment.

In the roof structure, there are certain areas in it that can be susceptible to water leaks and this is the reason why roof flashing is introduced as a sealer between the roof joints to prevent water leaking through the roof. There are different kinds of roof flashing materials to choose from, but the most common is the galvanized sheet metal, while aluminium and copper comes in a close second choice. There are many ways of installing roof flashing according to the areas on the roof deck, such as step flashing around the sides of the roof, chimney flashing, and saddle flashing around the top, but the measure used in installing roof flashing is by soldering.

Shingles or tiles are the outermost part of the roofing system which covers the underlayment and are the ones that are subject to the different kinds of weather condition, that is why their materials range from concrete, metal, or a good kind of wood, asphalt, clay, rubber, slate. Since the main function of roof shingles is to prevent any water leaking through the roof structure, they are usually designed as either flat or curved and installed by interlocking or overlapping with each other and they also come in many forms according to cost, weight, durability, color and style.
