Here is a quick comparison:
|Great wind uplift resistance (depending on attachment method)
|Superior wind uplift resistance
|Good resistance (depending on substrate)
|Superior resistance (depending on substrate)
|Lower due to air intrusion and fluttering of the membrane
|Higher – acts as an air barrier
So which is best?
- That all depends on your budget, type of building, and your performance expectations.
- A Fully Adhered system will out perform a Mechanically Attached system every time.
- When it’s time for a new roof, always consult with an experienced and trusted roofing contractor to determine the best system for your building.
Pro Tip: Mechanically Attached and Fully Adhered both require proactive preventative maintenance programs to prevent hazards from becoming leaks and to prolong the life of the membrane. Manufacturer’s require a maintenance program to keep the warranty in good standing. Rhoden Roofing offers a preventative maintenance program called RoofCare. RoofCare is designed to save building owners money, increase the lifespan of the membrane, and reduce headaches that come from unexpected & preventable leaks.
