Modified Rubber Roofing
Modified rubber roofing takes all of the features found in built-up roofing (BUR) and adds tensile strength because of the way it is applied. This type of roofing is essentially bitumen material that has been modified by having rubber added to it. The addition of the rubber is what gives it the extraordinary tensile strength. Modified rubber roofing has been in use within the commercial building industry for about 50 years.
How Does Modified Rubber Roofing Work?
Modified rubber roofing comes in sheets that are prefabricated at the manufacturer’s plant. This helps reduce the risk of human error in the installation process because it takes part of the human factor out of the equation. It also makes the process of application much less labor intensive, which saves you on the cost of labor. In fact, this type of roofing is probably one of the least expensive options available for commercial buildings.
Modified rubber roofing systems are usually made up of a two- to four-ply system, meaning that there are several layers applied to increase the performance and the protection offered by this type of roofing system. Building owners also have the option of having factory surfacing applied. The surfacing may be made of slag, mineral granules, copper, or aluminum.
There are many different kinds of materials available in modified rubber roofing, with each material offering slightly different advantages over others. In general, there are three applications types available. Some rolls of modified rubber roofing come with a peel and stick adhesive, and others have to be applied using a torch. The third time can be cold applied.
The Advantages of Modified Rubber Roofing
There are many reasons a commercial business owner may opt for modified rubber roofing over other options. Some of the advantages include:
- Modified rubber is extremely strong and tensile, which means that it can be stretched quite far and will still return to its original size and shape without any cracks appearing.
- Modified rubber is less sensitive to UV light, which makes this a very durable option in the hot Arizona sun.
- Studies show that if a reflective coating is applied to this type of roofing within its first five years, the life of the roof can be extended by 10 years or more.
- This type of roof is perfect for flat roofs, especially because it creates a durable surface that is safe to walk on regularly.
- When the roof gets toward the end of its life, sometimes it is possible to apply a new coat to prolong the wear of the roof.
- Modified rubber roofing is one of the least expensive commercial roofing options available.
- Repairs to this type of roofing are much more efficient and more successful.
- Insulation included in the roofing material increases the R value.
- Modified rubber roofing is resistant to splitting from thermal shock.
- It offers superior fire resistance.
- A modified rubber roofing system meets or exceeds building codes and insurance requirements.
- The chance for human error is greatly reduced.
- Labor costs are kept to a minimum.
- The system can easily be customized for your specific needs.
Modified rubber roofing is not recommended for roofs with a slope that is greater than a quarter of an inch per horizontal foot. When properly maintained, business owners can expect a life of at least 10 years out of this type of roofing system. Proper maintenance includes annual inspections and inspections after every major weather event.
