For the most part, you probably figure that as long as there is a roof over your head, it does not matter what kind of roof it is. This tends to be a sentiment for most. However, it isn’t so much the construction of the roof that is a worry. After all, most roofs are still built with wood beam frames and plywood sheets. What matters is the exterior surface that comes in contact with the sun and its damaging ultraviolet rays. What this exterior surface is made of can determine your roofs energy efficiency, lifespan and safety.
Out with the Old
Traditional roofing has either been tarring, shingles or combination of these materials. History has shown that tarring and shingles do not represent the most cost effective and energy efficient solution.
Tar
Tar is black, absorbs the sun’s rays and converts the energy into heat. Add to this that tar needs to be constantly resurfaced and doesn’t provide very good insulation.
Shingles
They provide exceptional aesthetic value, and they are durable; however, they conduct heat and can be heavy for roofs.
In with the New
New technologies have been introduced to the roofing market: single ply roofing systems. They are proving to be a durable, energy efficient and cost effective alternative. Companies that offer these single ply systems have formulated proprietary manufacturing techniques that produce an exceptionally durable single ply membrane. These manufacturing techniques use a combination of plastics and PVC construction, creating an ultra durable and impenetrable PVC roofing membrane. In fact, the durability is so great that they provide the same impenetrable surface years after the competing technologies need reapplication. In terms of energy savings and efficiency, the single ply roofs are huge cost savers, because manufactures of these systems understand the benefit of a high solar reflectance index (SRI).
“What is solar reflectance index?” you may ask. Well, it’s a term used to measure the reflectivity and ability of your roof to reject solar radiation. This is important because, when solar energy (light) hits an object, it quickly converts into heat energy. However, energy efficient single ply roofs are designed to have SRI levels approaching 90 percent, even after several years of use.
What’s Best for You
So, next time you see yourself spending too much money in the summer to cool down the space under your roof, consider the energy efficiency of single ply roofing solutions and how they can benefit you.
