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.

When it comes to the roofing system, being able to get a full idea about the basic components will provide the homeowner that opportunity of choosing well the right roof materials for his home. There are three important parts in the roofing system: underlayment, flashing, and shingles or tiles.

Before roof tiles or shingles are used to cover the roof, an underlayment is first installed, which is a waterproof material that is directly applied over the roof structure to serve as a protective layer from severe weather condition. Roofing underlayment comes in three main types and each type is designed to highly protect the roofing structure from all kinds of weather conditions and they are: the conventional asphalt felt paper or also called tar paper, which is actually made up of a high percentage of asphalt or bitumen, polyester and cellulose; the synthetic type is basically still of asphalt but with a mixture of fibreglass to provide more resistance from tear and make the underlayment stable; and the rubberized asphalt underlayment that consists of a greater percent of asphalt and rubber polymer, designed with a special back that acts as a waterproof seal between the underlayment and the roof deck.

Roof flashing is considered a major component in roofing because it functions as a sealer to certain areas in the roof, specifically the roof joints, where it is highly susceptible to water leaks. The galvanized sheet metal is known to be the most preferred roof flashing material, while the aluminium and copper can also serve well as a flashing material sealer. The common method used for installing roof flashing is through soldering and flashing is employed in many areas, such as step flashing around the sides of the roof, chimney flashing, and saddle flashing around the top.

The outermost covering that superimposes the underlayment is the roof shingle or roof tile, which is basically exposed to all kinds of weather condition and this is why roof shingles are made up of sturdy materials, such as 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.
