Dangers of Synthetic Slate Roofing

The use of synthetic slate has been on the market over 75 years. The first version was one made by Johns Manville. This was an asbestos shingle roof. This was openly advertised as an asbestos containing material that gave it excellent fire protection and longevity. Another manufacturer was Supradur who started manufacturing asbestos containing slate in 1947. Supradur had not completely switched to an asbestos free product till 1992.

Should you have one of these synthetic slate roof systems on your house, they are a health risk and must be removed by a licensed abatement contractor. The asbestos in this material are very friable and have significant health risks.

One of the problems with dealing with this material is that there is considerable safe off of the buildings and grounds in the removal area. Unless trained and licensed, this material should never be remove by a roofing contractor. This presents and added risk to your project. While abatement contractors know the safety procedure for handling this material they are rarely knowledgeable about working on roofs and providing proper watertight safe offs of your house.

Professional roofing contractors understand that your house must be left in a watertight condition at the end of each day. This is not necessarily the case with abatement contractors. Their focus is on the safe removal, while a good roofing contractor’s focus is on a watertight building throughout the project.

The planning of these type projects takes the added time and coordination between the roofing contractor and the abatement contractor. Preplanning is essential to proper execution. The safest planning requires the abatement work to start early and be finished by mid-day. Then the roofing contractor can finish the day closing the roof in.

The proper way to manage a rip and roof project is to only remove as much roofing in a day that can be roofed by the end of that same day. With the removal being performed by the abatement contractor the professional roofing contractor must control the abatement work to prevent more roofing being removed that can be properly safe-off by the end of the day.

Safety concerns  prevent the work being done next to each other. The new roof work cannot start until the abatement work is completed in a given area. This makes for long days as work proceeds.
