The building of an entirely brand new roofing is a challenging procedure. Different types of roofs need different ways of measuring. Gable roofs are quite simple to measure, whereas mansard and gambrel roofs are far more complex. This is why the waste can be a problem particularly if shingles have to be cut in order to be able to fit snugly into narrow space or attached onto the deck of the roof in rows that are even. Fortunately, the term “roof square” helps bridge the gap between these two kinds of roofing.
Another alternative for replacing the roof is to re-roof. It is also known as an overlay. the process involves putting an entirely new roof on roof that is already there. It is time-saving and cost-effective since it is not necessary to remove the roof. This alternative is, however, the recommended for homes which do not require the complete replacement of their roof. But, it isn’t advised if the damage is excessive, since it could cause the roof to become too heavy and the requirement for more layers.
It is one of the popular option for residential roofs with a low slope. It usually cost approximately $1.50 or $2/square foot and will last for approximately 10 years. Built-up roofing is one the oldest types of flat roofing. It is comprised of numerous sheets of felt roofing which are impregnated with asphalt , and laid out in layers that overlap. After the roofing is dried, it’s rolled up the finely crushed stone gets set in the hot tar, creating an extremely robust roofing.
