The term “modified bitumen roofing” refers to a roofing system that has been specially treated with asphalt. This treatment does not alter the physical structure of the roof like other asphalt roofing systems do, but instead it adds the ability to form metal ‘bumps’ on the surface of the roof which can then be used to seal and strengthen the roof more effectively. These are designed to increase the water resistance of the roofing system while at the same time increasing its thermal efficiency. They are more effective than traditional asphalt roofing systems because they are able to form metal ‘bumps’ at a much faster rate than regular asphalt roofing systems.
With this in mind, you should already have an idea of how these modified bitumen products can save you money and time, but what exactly is it? The term modified means that the material has been changed from its original state, but the actual process of changing it hasn’t changed much. Bitumen is made out of asphalt, so basically what you have is an asphalt roof being covered with a binder and coating. Once the binder and coating are applied, the asphalt layer beneath it is left undisturbed and the roofing system as a whole will be leaving intact. The actual material used in the roofing is what changes in the roof, but the way that the material is laid out and the method in which it is put on the roof still stays the same.
So how much does it cost to install these roofs? It actually depends on a number of factors, but one of the most important things to note is the actual weight and square footage of your home. A traditional asphalt roofing system will obviously be heavier than a modified bitumen roofing system. This is because the asphalt used in this type of roofing system is much thicker. But since the roofing system is still essentially a solid piece of metal, it isn’t as heavy as other types of roofs, which means it can be installed by contractors who are less experienced.
In terms of the actual cost to install the modified bitumen roofing system, you’ll find that it’s a lot cheaper than standard asphalt roofs. The reason for this is simple: asphalt is a very expensive product, and this is the easiest way to save money on your project. When you compare the cost of the roof with the cost of the binder and coating, you’ll quickly see that these two elements don’t add up to much, especially when you consider the investment that you’re making in your home by installing this system.
Another thing to consider is the fact that these roofs aren’t flexible in any way. Traditional asphalt roofs can be easily rolled up and moved, which allows you to install these types of roofs in places where traditional flat roofs would have been impossible. However, with modified bitumen roofing material, it is difficult to get these roofs in place. The material is too stiff and rigid to move easily, so instead you’ll find that you need a lot of nails or steel to get the roofing material to where you need it on your home. It’s not something that you want to do very often, and if you are going to try to install these roofs yourself, you’ll find that they take a great deal of effort and time.
Finally, you need to ask yourself what the modified bitumen roof life expectancy is. Basically, this is the amount of time that you will have to replace the roof after the first few years wear out. Obviously, the longer you live with the roof, the better chance that you’ll have long term success with it. When comparing the life expectancy of the roofing material, you should factor in the amount of maintenance that you’ll be doing over the years.
