Before the 1970s, asbestos was a popular material used in roofing and construction. Its heat and chemical resistance made it popular, plus it had fireproof properties, and it added strength to building materials. However, studies over the years have found that asbestos can cause a multitude of health risks, including cancer. Thanks to new safety regulations, asbestos was phased out of roofing products in the late 1980s. Today, all new products are asbestos-free, but does that mean that asbestos is no longer a threat? This article takes a closer look.
Roofing and Asbestos Exposure
Prior to the 1970s, almost all roofing material was combined with the lightweight, resistant, and inexpensive material of asbestos. Asbestos was considered more of a safety product, making roofs stronger and fire retardant.
Today, other materials have been found to replace asbestos, as it is dangerous and has negative health effects. While newer roofing materials are being used for new homes, some older homes might have products that still use asbestos:
- AAA hip and ridge shingles
- Careystone corrugated roofing
- Eternit asbestos shingles
- Fire-Chex ‘352’ shingles
- Flintkote roofing
- Johns-Manville Blak-Kap duplex roofing
Asbestos Containing Materials
Asbestos is a serious threat to roofing technicians as it can lead to adverse health effects if breathed in. All asbestos roofing materials can be broken down into two categories: friable and non-friable.
Friable materials break apart or disintegrate easily. These materials produce airborne asbestos, which can be inhaled or ingested, leading to serious health conditions such as lung cancer. Examples of friable materials are as follows:
- Niccolite (used under wood shingles)
- Pipe insulation in roof spaces
- Roof Paper
- Sprayed insulation
Non-friable refers to materials that are more resistant to breaking down. However, when a building undergoes demolition, these materials can break down and cause the asbestos fibers to become airborne.
- Cement roofing
- Felt paper
- Patch compounds
