Roofs and the roofing materials that make them come in numerous types and makes. Each of these have a certain set of features, characteristics, and properties that best fit the particular needs of each individual building. Factors such as cost, service life, aesthetics, the building’s structural integrity, and prevailing weather conditions, among other things, need consideration in choosing which type of roof and roofing shingle will best fit your home and provide for your roofing needs as best at it can.

Commercial Roofing



The term flat roof is actually a misnomer, since they usually have a slight, hardly noticeable incline to help drain off water. Flat roofs are common in commercial buildings because of its many advantages. It provides room for equipment such as air conditioning units to be kept out of sight and out of the way. Slope roofs also make it easy to install additional roofing fixtures such as solar panels, even rooftop gardens. The relatively flat surface also makes it easy if ever you choose to build an additional story on your building.


The different types of metal roofs provide different options which can work best is certain situations and the needs of specific types of buildings. They also help in keeping down the building’s heating costs by keeping it warm during cold days and cool during sunny weather. But perhaps the most attractive reason for a business to have a metal roof installed is its long service life, which can last up to 30 years and maybe more.


Thermoplastic polyolefin (TPO) roofing systems are one of the common types used for flat at low slope roofs. Being one of the least expensive roofing options in the market, TPO is ideal for business owners on a budget. Even then, having a TPO roof doesn’t mean you’ll be skimping on quality, since they are great insulators that keep the building’s heating costs down. They are also highly resistant to punctures and are watertight if installed properly.


Ethylene propylene diene monomer (EPDM) roofs are similar to TPOs in that they are mostly made from rubber. Like TPO EPDM roofs are much less costly than other roofing system options out there. EPDM is also waterproof and puncture resistant. They also bounce off ultraviolet rays and keep the building warm during cold weather and cool when the outside is hot. The basic difference between TPO and EPDM roofs that will have the greatest weight for your business is its lifespan: TPO lasts up to 20 years while EPDM can protect your building for 30 years.
