What Can I Do About My Mouldy Roof?

What Can I Do About My Mouldy Roof? Well for starters is your roof cavity well ventilated? It is easy to forget about the condition of your roof space when the attic is the least used area in the house. But, a poorly ventilated roof cavity can negatively impact the rest of your home.

Removing any mould that is present in the roof cavity is important for the overall health of your property, and your family.  Preventing mould from occurring in the first place is the best course of action, however, allowing moisture to escape your roof space.

Read on to find our suggestions for the best ways to remove and prevent mould growth in your roof cavity.

Why Does Mould Grow?

Mould grows because of moisture in the air. When the air is humid, condensation settles into the roof space and eventually causes mould.

The optimum conditions for mould to grow is where there is heat, water, and oxygen. However, mould easily preventable if your roof cavity is well ventilated.

Where Does Mould Grow In My Roof Cavity?

Mould can grow on almost any material in the roof cavity that is made from organic matter. Wood is the predominant material that is present in your roof cavity. Therefore, mould will more than likely grow on wood beams and joists first.

Cosmetic mould growth should be easy enough to remove. Although mould that has settled into the wood may cause structural damage. This would require extensive work completed by specialists to replace the affected joists.

However, wood is not the only material that moulds love. Insulation foam that is made using mineral wool is also a prime target. Unfortunately, once mould has begun to grow in the insulation foam, it will spread pretty quickly.

How Can I Remove Mould In My Roof Cavity?

Serious mould may need to be removed by a specialist. Not only may the mould be ingrained in the roof materials themselves, but mould can be dangerous to your health.

If you breathe in mould spores, you could feel a shortness of breath along with other irritant reactions. A small number of people are allergic to mould and so contact with mould can cause more serious reactions.

However, some visible mould in roof cavity spaces can be removed quite easily. Follow these simple steps for effective mould removal.

1. Preparation Is Key

If possible, choose a warm, dry day to remove mould from your roof cavity. Trying to remove ceiling mould on a wet day may be counterproductive as the spores may land on another cold surface.

2. Be Careful

Do not underestimate how harmful mould can be to your health. Take all relevant precautions to look after your health above all else. For example, open any windows and vents, ensuring that the space is fully ventilated. You should also protect other parts of your body by wearing gloves on your hand, and long-sleeved protective clothes. Masks that cover your eyes and mouth are also good ideas, providing they are specifically for use against mould.

As always, if in doubt, call in a specialist mould remover, or seek qualified roof inspection.

3. Cleaning Products

Bleach is the best and cheapest cleaning product to get rid of mould, although you can buy dedicated mould cleaning solutions. Check the manufacturer’s instructions in full before using any cleaning product, taking all recommended precautions.

A key point to remember, however, is to never mix bleach with a product containing ammonia, as the fumes are toxic.

4. Remove Any Disposable Items

If the mould has grown into the curtains or cushions, it is probably best to throw them away. You can clean the surface of those materials, although the mould will have grown inside the fabric and will spread.

5. Make Your Solution

Create a solution of 1 cup of bleach and 1 gallon of water. Using the solution in a spray bottle is best if you can.

Alternatively, white vinegar is a natural cleaning option that you could use. However, if using white vinegar, apply it directly to the mould without diluting.

Other good alternatives for natural remedies include using baking soda, adding just a sprinkle to warm water, or using borax. Add 1 cup of borax to 4 litres of water, then sponge the mixture over the affected area.

6. Time to Scrub

Scrub the mould as hard as you can, leaving the mixture to settle on the surface once the scrubbing is finished. A stiff-bristled brush is one of the toughest tools you can use and is perfect for a mouldy ceiling.

You should then rinse away all residue, and repeat if necessary for stubborn mould.
