Asbestos roofs are still found on many homes and small buildings across India, especially those built before the 1990s. They are durable, heat-resistant, and relatively affordable – which made them a popular choice for decades. But as these roofs age, homeowners often wonder: can you maintain them yourself, or should you always call a professional? Here’s what you need to know before you climb that ladder.

What exactly is an asbestos roof?

Asbestos roofing sheets are made from a mixture of cement and asbestos fibres. The material is strong, weather-resistant, and provides good insulation against heat – a big advantage in India’s hot climate. However, asbestos is also a hazardous material. When asbestos fibres become airborne and are inhaled, they can cause serious health problems, including lung disease and cancer.

Because of these risks, the use of asbestos in new construction has been restricted in many countries, and India has also tightened regulations on its handling and disposal. Still, many older buildings continue to have asbestos roofs that are decades old.

Can you maintain an asbestos roof yourself?

The short answer is: only to a very limited extent.

You can carry out basic, non-intrusive maintenance, but anything that might release asbestos dust – such as cleaning with high pressure, drilling, cutting, or replacing sheets – must be done by trained professionals with proper safety equipment.

Here’s what you can and cannot do:

• You can:

  • Remove leaves, dust, and debris from gutters and around the roof.
  • Check for visible damage from the ground or from a safe distance.
  • Keep the area under and around the roof well-ventilated and dry.

• You should not:

  • Scrub, sand, or pressure-wash the roof.
  • Drill holes or cut the sheets.
  • Walk directly on the roof, as it can crack and release fibres.
  • Attempt to repaint or seal the roof without professional advice.

Even small cracks or broken edges can release asbestos fibres, so it’s best to avoid any activity that disturbs the surface.

How to know if your roof contains asbestos

If your roof was installed before the mid-1990s, there’s a good chance it contains asbestos. Asbestos-cement sheets often have a greyish colour and a wavy pattern. However, visual inspection alone is not enough to confirm it.

If you’re unsure, you can contact a certified environmental testing laboratory or a local pollution control board–approved agency to take a sample safely and test it. Never try to collect a sample yourself.

Routine care you can safely do

If your asbestos roof is in good condition and not flaking or damaged, you can help extend its life with a few simple steps:

• Keep gutters and drains clear so rainwater flows freely.
• Trim nearby trees to prevent branches from rubbing against the roof.
• Inspect from the ground after heavy rains or storms for signs of leaks or damage.
• Ensure good ventilation in the attic or under-roof space to reduce moisture buildup.

These small actions can prevent water damage and slow down deterioration without disturbing the asbestos material.

When to call a professional

You should contact a licensed asbestos-handling contractor if you notice any of the following:

• Cracks, holes, or broken sheets
• Moss or algae growth that traps moisture
• Leaks or damp patches inside the house
• Dust or debris falling from the roof
• Plans to renovate, repaint, or replace the roof

Professionals have the right protective gear, tools, and disposal methods to handle asbestos safely. In India, such work must comply with the Central Pollution Control Board (CPCB) and State Pollution Control Board (SPCB) guidelines.

Safe disposal and replacement

If your roof is badly damaged or nearing the end of its life, replacement is the safest long-term solution. Modern alternatives like fibre-cement sheets (asbestos-free), metal roofing, or polycarbonate panels are safer and more durable.

Never try to remove asbestos sheets yourself. Improper removal can contaminate your home and surroundings. Always hire a certified contractor who can safely dismantle, transport, and dispose of the material at an approved facility.

Conclusion: Handle with care – and know your limits

You can do a little to keep your asbestos roof clean and functional, but you should never attempt major maintenance or repairs on your own. The health risks are too serious to take lightly.

By limiting your work to safe, surface-level care and calling professionals for anything more, you protect not only your home but also your family and community. In short: observe, maintain gently, and leave the rest to the experts.
