Workings of a House Roof

Roofing is an essential part of homes. And even long ago, a standard home would be using thatches and bundled reeds attached to rafters as basic roofing. Although very weather light, these are hard to assemble and even a skilled worker will take weeks working on it. Today, the thatch along with overlapping slates, clay tiles and cedar shakes are still being used. But from all this, the more commonly used roofing material is the asphalt shingle.
However you want to put it, a house roof has a common factor working from within. All of them have several layers forming a system that helps each other resist weather changes. Understanding how a roofing system works will help you converse freely with a contractor, and will also be advantageous when choosing your own materials.
Roofing systems are dependent on an overlap to shed water and resist being uprooted by winds. For this reason, asphalt shingles are nailed together and on to the roof. To add weather proofing to the roof, strips of factory applied adhesive may be used. The material used to make the adhesive is heat sensitive making the shingles self sealing under the sun.
With regard to the number of pieces needed to complete the roofing, shingles and the underlayment of the roof are measured in squares or in units of 100square foot. For each square, the weight may vary depending on the material and the consistency it has. And as per asphalt shingles, this holds true as well. You may choose to opt for lighter materials that after completion may way up to 200 lbs per square. If the material chosen is heavy and felt type, it can weigh as much as 425 lbs per square.
As of late, majority of construction jobs are hardly done with power tools. Done with a contractor or not, lying down of house roof tiles may be done with standard hand tools. You may see contractors use nail guns most of the time, but some of them get by using a 16 ounce hammer, nail pouch, utility knife, chalk line and utility snips that are used to trim shingles and cutting the drip edge. Tearing down the roof will require using the same materials. It will only require an additional shingle ripping bar that will assist in lifting and removing a shingle.
There are other materials beyond asphalt shingles as mentioned earlier. Clay tiles, cedar and steel panels are some of the more basic materials often used. All of which have different characteristics with different uses. Clay tiles are known to last almost forever but because of its weight, are hard to use. On the other hand cedars are thin, smooth and can last up to 40 years. Finally, the steel panels are all over and may be as widely used as the asphalt shingle. These may last as long as a decade or a century depending on the quality. Often people resist using it because they can be too costly.
House roofs can be considered a big project to work on. It may be advisable to ask assistance from a contractor. Make sure to remember details about house roofing to maintain the flow of construction and progress will be kept smooth.
