When we are planning for a new flat roof, it is essential to check whether it is suitable or in the budget for your house. There are different types of roofing material which shows different characteristics such as durability, long-lasting and expenses.
There are some following roofs listed and take a look which is better for you.
Single Ply PVC and TPO
These both are most affordable roofs for ordinary or industrial buildings. PVC (Polyvinyl Chloride) and TPO (Thermoplastic Polyolefin) single ply are the waterproof roofing material. They are light in weight so more useful for old buildings with asphalt roofs as this prevents extra adding of weight while installing new membrane and lower prices lower the project cost. PVC membranes are less flammable, so it is suitable for fire safety purpose. PVC and TPO include polyester thread reinforcement which provides durability and elasticity. The installation process is easy for these membranes and also lowers costs for air conditioning in summer due to their white or light grey coloring which reflects the sunlight. PVC has a lifetime around 30 years, and for TPO it is 50 years.
Double Ply Modified Bitumen
Modified Bitumen (MB) includes plastic and rubber-like qualities and sometimes referred to as the rubberized roof. The merits of this material are that it is tough, uniform in thickness, water resistant and tear resistant which is provided by its reinforcement with fiberglass and polymer. MB is high resisting to high temperature which makes it useful for harsh summer and freezing winters. The life of MB is around ten years, but it depends upon the quality of installation.
Four-Ply Built-Up Roof
Four-Ply Built-Up Roofs (BUR) are used from over 100 years as a trusted and tested method. These are the most common option until the invention of single ply. It is made by adding commonly several layers of tar and gravel to make it water resistant. Due to the presence of multiple layers makes it more reliable than other because if one layer is damaged the whole roof is not affected and function properly. The gravels make it more durable during harsh weather conditions and requires less maintenance than others.
Single Ply EPDM Flat Roofing
EPDM (Ethylene Propylene Diene Monomer) is most popular among commercial roofing. It is based upon rubber roofing technology which makes it durable, flexible and resistant. Rubber makes it more flexible which prevents the cracks through structural movement. It is resilient to harsh weather conditions and shows little wear after some time. It requires less maintenance and easy to install. Lifespan is around 12-25 years.
The metal roof has their allure since they are non-combustible, they divert the sun’s warmth far from the building (bringing down cooling costs), and because they are durable. They are additionally effectively adaptable around flashings and different anomalies of the roof. It is an increasingly perpetual alternative to roofing, as metal rooftops are not as effectively supplanted, nor do they should be because of their strength.
