The weakest point of a roofing system will always be the seam between two pieces of material. At these seams, there is a natural break in the material that can allow precipitation to work its way down into the roof and cause problems. Using larger rolls of tar paper or rubber roofing does not make sense because the materials will be heavy and hard to handle. Spray-foam roofing, on the other hand, can be sprayed on as a liquid, which when dry, will form one solid roofing membrane, and this is just one of the advantages of spray roofing.
Spray roofing, or polyurethane foam, has one other common usage besides creating roof membranes. It is used as an insulator. Rubber roofing membranes and tar paper offer little in the way of insulation. When they absorb heat from the sun, they allow this heat to seep into the building below. If you use foam roofing, it will help to prevent heat or cold from seeping into your building. By preventing your building from heating up during the summer or cooling down during the winter, your spray-on roofing will help to reduce your HVAC costs.
Foam roof coatings has been in use for several decades. Over that time, people have had plenty of opportunities to get a feel for how well foam roofs perform. There are foam roofs that have lasted for decades and still look to be in good enough condition to last for a few more decades. Thus, when you use a foam roof, you should see a decrease in your replacement and repair costs.
A built-up roof can weigh a lot. The more a roof weighs, the more strain it puts on the building below. Foam roofs are made of a much lighter material, so they will put far less strain on a building. If you live in an area that receives a lot of snow, you should try to keep your roof weight down, so that you don't have to worry as much about the snow causing your roof to come crashing down.
Your choice of roofing material can have long-lasting effects. The wrong material will lead to higher costs down the road. While asphalt roofs are the least expensive roofing material, they do not provide the best protection for your home. If you are serious about protecting your building from the elements and yourself form unnecessary costs, you will choose a foam-roofing system.
