Asbestos Roof Tile
Older homes and office buildings may be equipped with roof tiles that contain asbestos. As long as these
tiles are in good condition, residents and office workers should not be concerned with dangerous levels
of exposure. However, if the roof tiles shows signs of deterioration, health officials recommend taking
steps to ensure that no person is exposed to hazardous asbestos fibers.
Sealing Damaged Roof Tiles
Health officials do not recommend replacing or removing damaged asbestos-containing roof tiles. Disturbing
the already-damaged tiles can stir up asbestos dust and release the dangerous fibers into the air, putting
at risk the health of everyone in the general vicinity of the building. Instead, it is recommended that
the damaged tiles be sealed. When the sealant dries, it hardens so that the asbestos particles are trapped
inside and prevented from escaping into the air.
Two different types of sealant are used to seal asbestos-containing roof tiles:
- Emulsion (water-based) coatings
- Solvent-based coatings
Each has its own benefits and may include increased environmental hazards if not properly applied. Not
all surface coatings and paints are suitable for sealing asbestos-containing materials, and some substances
may even increase the risk of fire. When the product is being applied to the roof, make sure to use
no power tools or high-pressure systems, which further damage tiles and release asbestos into the air.
Residents who take proper precautions to seal their asbestos-containing roof tiles still must exercise
caution. The ceiling space underneath the roof, especially if the tiles are crumbling and brittle, might
contain dangerous levels of asbestos particles.
