How Do You Clean an Asbestos Roof?

Getting Set Up

1). Secure the end of the ladder on a stable, flat surface, preferably the soil or grass. Put up the extension section of the ladder to a height of 2 or 3 feet above the start of the roof.
2). Climb to the top of the ladder and securely tie the ¾ inch rope to the uppermost step of the ladder. Throw the rope over the spine of the roof. Search for a suitable anchor and secure the rope to it.
3). Put on the protective mask and rubber gloves. Fill the bucket with water and add the appropriate amount of surface biocide by following the directions on the container for the surface area of the roof.

1). Attach the handle of the bucket to an upper step of the ladder with the metal hook to make it easier to wet the mop. Use the mop to completely cover the surface of the roof with the mixture. Let the chemical work on the dirt and plant matter for 30 minutes.
2). Wash off the roof with the hose. Clean out the bucket and mix the outdoor surface cleaner with the recommended amount of water.
3). Mop the roof again with this mixture. Do not allow the cleaning fluid to dry as it is much easier to remove the dirt when working with a wet surface.
4). Use the hard plastic bristle brush to gently scrub all dirt and plant matter from the asbestos roofing. Utilize the nonmetal trowel to dig into the corners where plant roots have set. Place all large plant matter in plastic bags.

1). Wipe the roof down with a rag and fresh water to remove any existing debris. Hose the entire surface off.
2). Collect all debris that may have fallen to the ground and place it in the plastic bag along with your gloves, face mask, brush, rags and mop head.
3). Seal the plastic bags containing debris and place them in a secure garbage area. Untie the rope from the anchor and take the ladder off the roof.
