Can you maintain your fibre cement roof yourself? Here’s the answer
Fibre cement roofs are a common sight on Irish homes, farm buildings, and sheds. They’re durable, weather-resistant, and have a traditional look that suits both rural and suburban settings. But even though fibre cement is tough, it still needs some care over the years. The big question is: can you look after it yourself, or should you call in a professional? Here’s the answer – and a guide to what you can, may, and should do.
What exactly is a fibre cement roof?
Fibre cement is a composite material made from cement reinforced with fibres, which makes it strong and resistant to Ireland’s damp, windy climate. Older fibre cement sheets (installed before the late 1980s) often contain asbestos, while modern ones are asbestos-free. That distinction is crucial, because it determines what kind of maintenance you can safely do yourself.
A fibre cement roof can last anywhere from 30 to 50 years, depending on the quality of the material, the local weather, and how well it’s maintained. Over time, moss, algae, and small cracks can appear, and that’s when maintenance becomes important.
Are you allowed to maintain it yourself?
The short answer is: Yes – but with some important exceptions.
-
If your roof contains asbestos (common in sheets installed before 1988), you must not clean, sand, or cut it yourself. Asbestos fibres are hazardous when disturbed, and any work on such materials must be carried out by licensed professionals with the proper safety equipment. You can, however, safely clear leaves from gutters and keep the area around the roof tidy.
-
If your roof is asbestos-free, you can handle basic maintenance tasks yourself – such as removing moss, cleaning gutters, and checking for visible damage. But you need to do it carefully to avoid damaging the surface or compromising the roof’s protective coating.
How to check if your roof contains asbestos
If you’re unsure whether your roof contains asbestos, look for markings on the back of the sheets. Newer, asbestos-free sheets are often marked with “NT” (new type) or “AF” (asbestos-free). If you can’t find any markings, you can have a small sample tested by a certified laboratory or ask a roofing specialist to inspect it. It’s a small cost that can prevent serious health and legal issues later.
Routine maintenance – what you can do yourself
If your roof is confirmed asbestos-free, there are several simple maintenance tasks you can safely take on:
- Clean gutters and downpipes at least once a year to ensure proper drainage.
- Remove leaves, branches, and debris from the roof surface, especially after storms.
- Keep an eye on moss and algae. A light green film is harmless, but thick moss can trap moisture and shorten the roof’s lifespan.
- Inspect for cracks, loose fixings, or damaged sheets. Small issues can quickly worsen if left unattended.
Always use proper safety equipment when working at height, and avoid walking directly on the sheets – they can crack under weight, especially if they’re older.
Cleaning and painting – when to call in the experts
While you can handle light maintenance yourself, larger jobs should be left to professionals:
- Roof cleaning: Professionals use low-pressure washing and suitable cleaning agents that won’t damage the surface. High-pressure washing can strip away the protective coating and cause leaks.
- Roof painting or sealing: A new surface treatment can extend the life of your roof, but it requires the right materials and technique to ensure durability.
- Repairs: Cracked or porous sheets should always be replaced by a qualified roofer, particularly if the roof is old or contains asbestos.
Signs that your roof needs professional attention
Watch out for these warning signs:
- Persistent dark stains or discolouration that don’t wash off
- Cracks, flaking, or crumbling edges on the sheets
- Damp patches or leaks in the attic
- Moss growing in the joints between sheets
The sooner you have a professional inspect the roof, the easier and cheaper it usually is to fix the problem.
How to extend your roof’s lifespan
A fibre cement roof can last for decades if you look after it properly. Here are some good habits to adopt:
- Carry out an annual roof inspection, ideally in spring after the winter weather.
- Ensure good attic ventilation to prevent condensation and moisture build-up.
- Trim back overhanging trees to reduce shade and moss growth.
- Have the roof professionally inspected every 5–10 years to catch early signs of wear.

Conclusion: You can do a lot yourself – but not everything
You can certainly take care of the light maintenance on an asbestos-free fibre cement roof. Keeping it clean, dry, and free from damage will go a long way towards preserving it. But if your roof contains asbestos, or if you need deep cleaning, painting, or repairs, always call in a professional.
By knowing where to draw the line between DIY and professional work, you can save money, stay safe, and make sure your roof protects your home for many years to come.
