How to maintain a Asbestos Roof

When was the last time a roof on an older home needed to be replaced? There is a good likelihood that asbestos was used in the shingles, sealant, gutters, or grouting.

Asbestos cement shingles were extremely popular from the 1920s through the late 1980s. Many of these roofs are still in use after a 30- to 50-year lifespan.

Removal of asbestos should be left to the professionals. When performing asbestos roof maintenance on your own, it’s critical to observe safety precautions.

Public Safety

Asbestos fibers are potentially hazardous to the health of anyone who comes into touch with them. Always offer advance notification to your neighbors and restrict access to the area where you are working.


·   Inform your neighbors about the work you’re about to do and when

·   Prevent access to the surrounding work area

Site Preparation

Protect your property and grounds by creating physical barriers and gathering all necessary goods in one location.


·   Keep all doors and windows shut

·   Cover up any air vents

·   Turn off the home’s air conditioning

·   Place a tarp or plastic sheeting around the area

·   Get asbestos waste removal bags on hand, along with duct tape

·   Remove any lawn equipment, toys, or other objects in the vicinity

·   Buy separate cleaning tools like mops and rags

·   Get all your equipment outside and in one place, to avoid the need to go back inside or walk around too much

Personal Protection

Asbestos personal protective equipment is required. It is insufficient to wear layers or disposable work clothing.

Take no chances, as asbestos fibers are capable of passing through other materials.


·   Wear disposable asbestos clothing that has a hood and protects your shoes

·   Wear an asbestos respirator that has an airtight fit (that means shaving any facial hair)

·   Before removing asbestos work clothes, keep the respirator on and mist the clothing with water

·   Place used clothing in an asbestos waste bag and seal it

·   Always take a shower after removing asbestos gear


·   Never shake dust or dirt off clothing

·   Don’t keep or reuse any of the disposable protection garments

Handling Asbestos

It is standard practice when working with asbestos to dampen down all of the components. However, you cannot do so on a roof.

To begin, asbestos shingles are infamous for their slickness. Homeowners who are inexperienced should avoid working on slick or damp surfaces. As a result, it is critical to minimize dust and breakage. Once the materials have been set out on the ground, wet them down.


·   Asphalt shingles are often brittle, so work slowly to avoid breaking them

·   Carefully lower shingles to the ground


·   never drop or break asbestos-containing materials

·   don’t slide shingles across each other

·   sand, scrape, or brush shingles

·   don’t drill holes into asphalt shingles

Waste Disposal

Unlike asphalt shingles, asbestos roofing materials cannot be thrown away. The shingles and any other roofing materials, as well as any other materials, must be properly disposed of in asbestos disposal bags.

Everything must be double packed and then sealed with duct tape. Carry out this method regardless of whether you suspect the substance is polluted.


·   Get asbestos disposal bags

·   Wet down all asbestos-containing materials and dispose of them in asbestos disposal bags

·   Clean the area by wet mopping it with water that has a few drops of environmentally safe liquid mixed in or hire an asbestos cleaning crew

·   Have an asbestos waste removal service take the trash away or bring it to an asbestos-accepting landfill

·   Toss anything used to clean the area, like cloths, mops, and contaminated buckets


·   Don’t take asbestos material to the regular dump

·   Never place asbestos material in a domestic trash can

·   Never sweep, dust, or vacuum up debris

Tools and Equipment

When working with asbestos cement shingles, special precautions must be used. Drilling or the use of other power equipment is prohibited, as this will result in the fibers flying out.

These shingles are brittle and will eventually break, but they can be avoided by working slowly and carefully.


·   Only use hand-operated equipment or very carefully use low-speed tools


·   Don’t use power washers or any high-pressure water jets

·   Don’t use power tools like grinders or saws

·   Don’t use compressed air tools

·   Don’t use abrasive cutting or sanding discs

·   Don’t use electric sanders or grinders

·   Don’t use household vacuum cleaners

Safety To-Do List

Here’s a safety recap in a convenient to-do list.

1. Tell your neighbors that you’ll be working with asbestos and ask them to keep their windows shut, doors closed, and HVAC off during that time.

2. Close your windows, shut the doors, turn off the HVAC, and block off any vents.

3. Remove any objects in the area.

4. Place a tarp down around the area.

5. Place plastic sheeting or drop cloths around the area.

6. Cordon off the area with rope or barrier tape.

7. Gear up in asbestos-rated personal protection equipment – disposable clothing, boots, and a respirator.

8. Work carefully when cleaning, removing, or repairing shingles.

9. Lower any pieces down carefully.

10.  Wet any roofing material once it’s on the ground, using water with a few drops of liquid soap.

11.  Wet the surrounding areas.

12.  Double bag waste in asbestos disposal bags, then seal it tight with duct tape.

13.  To remove clothing, mist yourself down with water, wipe off the boots, then carefully remove the coveralls and respirator.

14.  Place the clothing in waste removal bags, then double bag it and seal.

15.  Shower off.

16.  Have an asbestos waste removal take the trash away or bring it to an asbestos-accepting landfill.
