MODERN ROOFING SYSTEM

 Roofing systems come in a variety of forms, from shingles and tile to steel and asphalt. In some cases, culture influences the type of roofing system, such as tile use in areas with ties to Spanish culture. In areas with extreme weather conditions, such as high winds, steel roofing may supersede the more fragile shingle. In all cases though, the roofing system plays a critical role in maintaining the integrity of the home's envelope (temperature, moisture, and air pressure control).

The type of the modern roofing system:
1.Thermoplastic Roofing - TPO roofing systems are among the fastest growing commercial roofing systems. Made of an especially durable material with a low-temperature flexibility and a high-temperature tolerance, these roofs are exceptionally resistant to ultraviolet, ozone and chemical exposure. TPO roofs can be expected to have a lifespan of 20+ years, and also feature a high resistance to fire, punctures, chemicals and high winds.

2.EPDM Roofing: EPDM roofing offers superior durability and versatility, making it one of the longest lasting types of commercial roofs available. EPDM commercial roofing systems are also typically easier to install, maintain and repair than most other types of commercial roofs.
 EPDM roofing is short for Ethylene Propylene Diene Monomer roofing - otherwise known as rubber roofings. An EPDM roof is a single-ply membrane, meaning there is only one layer of roofing material. EPDM thickness ranges from 30 mils to 100 mils, with the most common thickness being 45 or 60 mils.

3. Photovoltaic Panels: As energy costs continue to rise and America looks towards green and sustainable energy, many building owners are turning to solar energy roofing systems. PV solar panels installed over a rooftop or used with glass, membrane and roof-mounted tile, absorb sunlight and convert it to energy that can be used to power a building. Although not in wide use, PV panel roofs offer great potential to conserve energy and control skyrocketing costs.

4. Green Roofs: Perhaps of all the types of commercial roofs available today, green roofing systems have experienced the greatest surge in popularity in the last few years. Sedum green roofs are typically flat roofs that are partially or completely covered with vegetation and soil and planted over a waterproofing membrane. Green roofing systems reduce the urban heat island effect by soaking up heat and also are found to dramatically improve a roof's insulation value - lengthening the lifespan of the roof by as much as two to three times.

 Green Roofs can be achieved using a standing seam system as a robust component of the system. Traditionally single ply sheets were used as a base for the green roof matt. Aluminium standing seam sheets offer the ability to enable the laying of larger roof areas with out the high risk of leaks caused during the installation of the soil and clay system over membrane. Extensive green roofs can be subdivided into a range of different systems dependent upon the composition and depth of the substrate and on the plant species used.
