Asphalt also known as bitumen is a molten petroleum product coming as a result of either natural deposits or the refining process that makes a purer product. Its nature makes it very thick and it has become a popular roofing product for homes seeking to create a watertight solution. Asphalt products for use in this purpose are many and with differing characteristics. Here are tips and an overview of the different options available in the market to help you find one that matches your needs.
1. Asphalt shingles
These make a great alternative to roll roofing in windy conditions. This is because they are easy to handle and easier to apply thanks to their small size. They also offer the advantage of being easy to replace in case you have storm damage.
2. Fiberglass mats vs. organic shingles mats
During installation, asphalt gets embedded to mats. You have the option of fiberglass or organic shingles. Organic shingles are heavier since they require about 40% more asphalt to hold the shingles together when compared to fiberglass. Fiberglass are popular with modern day home owners because they have a higher fire resistance rating compared to organic shingles.
3. Three tab shingles vs. architectural shingles
The choice you will be making here is about the final look you desire. Three tab shingles are so named because each shingle has three separate tabs at the bottom. The way they are layered up over the preceding row means the solid part at the top is not visible giving the impression of individual pieces. The architectural shingles have a separate raised portion where additional layers create a multidimensional look.
4. Single vs. double layer coverage
The choice here depends on the kind of weight roll roofing you are using as well as the manpower and time needed to complete the building. Lighter weight roll roofing calls for a double later coverage to make it water tight and prevent any leakage. With heavy weight roll roofing a single layer is enough. Combining lightweight roll roofing with a double layer provides easy maneuvering provided you have enough manpower. A heavy roll single layer roofing has the advantage of being completed faster with less manpower.
5. Natural vs. modified asphalt
In this case the major factor is cost. Natural asphalt does not require refinement reducing the number of inputs which reduces its cost significantly. The disadvantage is that it gets stiff and hard in winter and is more susceptible to cracking. Modified asphalt can withstand different weather elements and has a longer lifespan. It has a higher upfront cost but should prove a better long term investment.
6. Type of fiber in the matting
This applies for roll roofing. There are three options of matting integrated in the roofing material. The type of fiber is important because it determines the lifespan and cost of the roofing. There are three options. At the opposite ends are rag matting and fiberglass matting. Rag matting is the less costly option but has a shorter lifespan while fiberglass costs a lot and offers longer lifespan. You can also opt for plastic matting which is mid-level offering both economical and durability benefits.
