Installing a membrane roofing system on your building will help to ensure your roof’s longevity. Membrane roofing systems are durable and low-maintenance choices for commercial properties. What makes them different from traditional asphalt roofs?
A membrane roof is unlike a regular shingled roof, due to its lack of seams. Commonly, flat roofs have problems with water leaks because of drainage difficulties. But with a seamless roof, layers of material are fused to make one complete covering for the building. Because of this, it is virtually impossible for water to penetrate the building. If a leak does occur, the source of the problem can be identified immediately and repaired promptly.
Buildings with asphalt roofs often require more frequent roof replacements because asphalt is dark, absorbing heat from sunlight and causing the materials to expand and contract. This thermodynamic process weakens the shingles, loosening and degrading them over time. Membrane roofing systems are usually constructed out of white UV-ray-reflecting material. The roof will not suffer the same deteriorating effects from long hours of sun exposure.
What Kinds of Membrane Roofing Systems Are There?
Membrane roofs come in three varieties:
- Modified Bitumen
Thermoset roofs are constructed out of synthetic rubber sheets. Each sheet is arranged and bonded to the adjacent sheet with high temperatures. Thermoset roofs are known for their strong seams, as the rubber bonds chemically once the sheets are joined together. This type of membrane is known as the strongest, most durable and long-lasting of all three types.
Thermoplastic roofs are made of PVC and the construction is much like a thermoset roof. Thermoplastic roofs have lower overall costs because the seams are not as strong as those found in thermoset roofs, but still extremely successful at keeping out water.
Modified bitumen is considered a membrane roof, but still contains asphalt along with a concoction of other compounds. Modified bitumen materials can be melted onto a roof using a heat source or applied through the use of an adhesive.
Membrane roofing systems are ideal for companies looking for a long-term roof investment with minimal care required. They are able to withstand both ends of the weather spectrum: harsh cold and high heat. They are also resistant to hail damage. While most roofing warranties cover damage for a few decades — 20 to 30 years — these roofs can potentially last for 50 years when installed correctly, offering businesses extended protection.
Growing in popularity, membrane roofs are beginning to be installed in residential properties with flat or barely sloped roofs. Contact the professional team at Knockout Roofing if you want to install a membrane roofing system for your home or business.
