Mechanically Fastened Roof Membrane

A mechanically fastened roof membrane is a type of roofing system that utilizes mechanical fasteners, such as screws or nails, to attach the membrane to the roof deck. This method of attachment is in contrast to adhered roof membranes, which use adhesives to bond the membrane to the deck.

Mechanically fastened roof membranes offer several advantages over adhered membranes. They are generally more resistant to wind uplift, as the mechanical fasteners provide a stronger connection between the membrane and the deck. They are also easier to repair, as the fasteners can be easily removed and replaced. Additionally, mechanically fastened roof membranes can be installed in a wider range of weather conditions, as they do not require the use of adhesives that can be affected by temperature and humidity.

Mechanically fastened roof membranes have been used for many years and have a proven track record of performance. They are a popular choice for commercial and industrial buildings, as well as for homes in areas with high winds. There are different types of mechanically fastened roof membranes available, each with its own unique set of properties and benefits. Some of the most common types include:

  • PVC membranes
  • TPO membranes
  • EPDM membranes
  • Modified bitumen membranes

The type of mechanically fastened roof membrane that is best for a particular application will depend on a number of factors, including the climate, the slope of the roof, and the budget. A qualified roofing contractor can help to determine the best type of membrane for a specific project.

Durability


Durability, Home2

The durability of mechanically fastened roof membranes is a key advantage over adhered membranes. The mechanical fasteners provide a stronger connection between the membrane and the roof deck, which makes the roof more resistant to wind uplift and other weather conditions. This is especially important in areas with high winds or storms.

For example, a study by the National Roofing Contractors Association found that mechanically fastened roof membranes were able to withstand wind speeds of up to 110 miles per hour, while adhered membranes failed at wind speeds of 75 miles per hour. This difference in performance is due to the fact that the mechanical fasteners provide a more secure connection between the membrane and the roof deck, which prevents the membrane from peeling or tearing away.

The durability of mechanically fastened roof membranes is also important for protecting the building from other weather conditions, such as rain, snow, and ice. The strong connection between the membrane and the roof deck prevents water from penetrating the roof and causing damage to the building’s interior.

In addition to being more resistant to wind uplift and other weather conditions, mechanically fastened roof membranes are also easier to repair than adhered membranes. The fasteners can be easily removed and replaced, which makes it quick and easy to repair any damage to the membrane.

Ease of repair


Ease Of Repair, Home2

The ease of repair is a key advantage of mechanically fastened roof membranes over adhered membranes. The mechanical fasteners can be easily removed and replaced, which makes it quick and easy to repair any damage to the membrane.

For example, if a mechanically fastened roof membrane is damaged by a hailstorm, the damaged section of the membrane can be easily removed and replaced. This is a much simpler and less costly repair than repairing an adhered membrane, which would require the entire section of the membrane to be replaced.

The ease of repair of mechanically fastened roof membranes also makes them a good choice for roofs that are likely to need frequent repairs, such as roofs on commercial buildings or roofs in high-traffic areas. The ability to quickly and easily repair the membrane can help to extend the life of the roof and reduce the overall cost of maintenance.
