Torch down roofing installation in Illinois by JB Roofing

Torch down roofing installation life span is usually between 10-20 years, which depends on the number of layers.
- 10-15 years life span applies to a double layer torch down roof installation, which includes a base and a single protective torch down layer
- 15-20 years life span is achieved by applying a smooth torch down layer over the base and a protective granules surface layer on top of it.
Properly performed torch down roofing installations are very strong, their flexible surface resistant to extreme weather conditions such as wind or hail, and easy to repair in case of any mechanical damage.

Heavily wooded areas might cause torch down roof installations life span to diminish slightly unless you remove debris and leafs on regular basis – this can be easily done by using a leaf blower.
