Commercial properties tend to be large, and because of their size, the roofs tend to be flat. When you have a pitched roof, your roof does not have to be completely water tight. It just has to shed water. On the other hand, water can pool up on a flat roof, so your roof has to be completely water tight. The most common way to make a flat roof is to use built-up tar roofing or BUR. You can, however, gain better value for yourself by using a rubber roofing membrane.
The Story of BUR
A BUR roof is made from alternating layers of tarpaper and asphalt tar. The seams in one layer of tar are offset so that the next layer's seams fall in the middle of the tarpaper. By impregnating each layer with tar, you create a waterproof final product. On the other hand, a constant onslaught of the sun's rays will evaporate the volatiles right out of your tar, leaving it brittle and prone to cracking. A BUR will last for 20-30 years before it needs to be replaced. However, a BUR roof will likely need maintenance well before it hits its expected lifespan.
The Story of a Rubber Roofing Membrane
Rubber roofing has not been on the market for as long as BUR, but it can still offer you good value for your money. Rubber is completely waterproof, so the most important component of your roof is the seam. As long as your installer does a good job with the seams, rubber roofing can last for up to 50 years before it needs to be replaced. This can save you a lot of money on replacement costs. While you pay a little extra for a white membrane, the white color will save you money because it reflects the sun's energy away from your roof. In fact, you can save up to 20%.
In order to get ahead in business, you need to save money where you can. A white rubber roof will cost more to install than a BUR roof, but you will end up saving money. The key is that a rubber roof will outlast a BUR roof. Moreover, a white rubber roof will save you money on your monthly cooling costs. You could replace your BUR roof up to three times before you have to replace your rubber roof even once, so a rubber roofing membrane is the better value over the long term.
