The Key Elements of Great Roofing
Basic Components That Comprise the Roofing System
To be able to maintain one’s home in the best condition, a homeowner should take time to know and learn about the basic structures so that when the time comes for a major repair or for an additional improvement to be done, there won’t be much of a problem in discussing thoroughly these projects with the contractor.
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. There are three important parts in the roofing system: underlayment, flashing, and shingles or tiles.
Once the roof structure is in-place, an underlayment is directly applied over it, which is a material that is waterproof and functions as a protector of the roof structure from the harsh weather condition. 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. The most common material for roof flashing is the galvanized sheet metal, but some homeowners would prefer the aluminium and copper metals. 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.
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. Roof shingles or tiles come in a variety of choices, depending of the cost, weight, durability, color and style, but their design is just basically made up of flat or curved tiles that interlock or overlap with each other.
