How to Install Roofing – Step by Step Guide
As the name suggests, roofing felt is the product used to adhere the roofing shingles on a building or any other structure. It is quite similar to asphalt shingles and it is used mostly in Europe, particularly in Scandinavia where this product has been used for more than a century. The t50 staples are the most commonly used nails in roofing industry but there are many other options available. This article looks at the advantages of using roofing nails as opposed to the felt and also at the disadvantages of using these nails.
Roofing felt, which is often called tar, asphalt shingles, clapboard, and cedar shakes were commonly used as roofing materials before asphalt was introduced in the US in the thirties. Using asphalt shingles was simple because these materials already had the necessary adhesives and weather resistant properties that were made for use on roofs. The disadvantage of using these substances was that they cracked easily, mildewed very easily, did not last long, required an extremely high maintenance cost, and were therefore not really practical for homes. Installing asphalt shingles was therefore a major renovation job that was best left to the experts.
Roofing felt was more appealing because it was both cost effective and easy to install on sloping areas. These felt sheets used polyethylene fibers which could be glued onto the asphalt shingles with the help of heat or mechanical sealant. Polyethylene was in itself a significant investment and hence was not likely to be replaced too often. Also, these sheets were relatively slippery which added to their attraction factor and their lack of practicality when it came to use on sloping roofs.
With asphalt shingles, the cost of having them installed was higher and so too was the possibility of having them replaced too soon. Also, the appearance of these shingles had a very contemporary look and so they were not likely to be very attractive. The appearance of the roofing felt also had its own disadvantages. It was heavy and hence very inconvenient to carry. It also took a lot of effort to cut the felt properly so that it fit perfectly and looked even.
The most important thing about the roofing project, however, was the need to invest in an underlayment or roofing membrane. This is the substance that goes between the rubber and the shingles and helps to prevent water penetration and dampness between the rubber and the shingles. Without this underlayment, there would be no chance whatsoever of dampness being prevented and water running down between the shingles would significantly reduce the life of the roofing. Thus the first step in how to install roofing should always be in finding and buying a good quality underlayment which will make sure that the roof area gets the much needed protection from moisture and condensation.
The second step on how to install roofing is to secure the rubber edge of the roof underlayment to the roof edges. This can be done with clips or nails. If the flashing is to be used then it is best to go for steel flashing since it is rust-proof and hence can be used for many years. Once the rubber edge of the underlayment is firmly fixed, then the rest of the roofing installation process will be much easier. The flashing can be secured either at the bottom, middle or top of the roof depending on the climatic conditions and other factors. Installation of flashing is best done after the rubber edge of the underlayment is already fixed on the roof surfaces.
