Why Is My Loft Damp?

Do you have a damp loft? How do you find out if you do?

Condensation and excess moisture can build up quickly at any time of the year. If the right actions are taken, then it can be reversed, and the issues can be prevented from happening again. Damp and mould can bring significant risks to your health and when left without treating it, they can rot away at the timber battens in the roof! So, it’s important to prepare for prevention, causes and treatment in case this happens to you.

The Signs To Look Out For

Even though condensation and dampness are most common in autumn and winter, there is a chance that throughout the year your loft could be exposed to moisture which will create a damp loft.

The first signs to be aware of are:

–    Damp

–    Moisture on the inside of any Velux windows

–    Black spots on your walls

–    Mould spores on items in the loft

–    Broken roof tiles (visible from the outside)

–    Cracked leadwork

–    Leaking pipes and guttering

Once you have identified these signs, you can find the cause / solution of the problem – therefore you can begin to tackle the main issue.

Condensation caused by Loft Insulation

Loft insulation has many benefits from reducing your utility bills, increasing energy efficiency and helping the planet, and giving you a more comfortable home environment, as well as adding more value to your home.

But badly-installed loft insulation can limit the ventilation flowing through the loft, by blocking the eaves. Your home will be nice and warm, but ventilation is needed to take moist air out of the loft, before it forms into condensation. Many insulation installers, including in new build properties, alas let the insulation block the eaves.

If you do have condensation in the loft, it’s worth trying to fix the root problem. However if you can’t then installing a natural substance like sheep’s wool will keep your loft eco-friendlier and be able to absorb any moisture, avoiding the risk of condensation. The loft may however smell like wet sheep!

Over-Filling Your Loft

Another common cause of condensation can be overfilling your loft with storage.

If your loft is overcrowded, this can also block ventilation. The loft constantly needs breathing space so the air can flow, allowing your home to be warm in the winter and cooler in the summer.

Squashing any insulation will affect its performance (usually reducing it by at least 50%) as insulation works on being fluffy and trapping air inside it. So it’s important to not compress it with floorboards or boxes, in one of our recent blogs: ‘The Dos and Don’ts Of Boarding Over Loft Insulation’, we explain more.

Loft Hatches And Down-Lighters

If hatches and downlighters are installed incorrectly, moist air from the house will be able to get into the loft, which can cause condensation. Having a poorly ventilated loft with the warm air from below mixing with one another can cause damp, mould and rot to form.

You should ideally place downlight covers over each downlight, so that air cannot pass around them. And seal all around the hatch, which should itself be insulated, too.

It’s important that when you have any loft work and you are not confident enough to do it yourself, to get a professional; contact us to see who your local installers are.

How To Treat Condensation

If you are suffering from a damp loft, don’t ignore this issue.

To make sure that your loft becomes properly ventilated, there needs to be a place for the damp air to disperse outside. There are a few ways to achieve this:

–    Make sure that the ventilation spaces are clear of insulation or storage boxes.

–   Don’t board directly on to the joists as then the warm and humid air rising through the ceiling and insulation has nowhere to go and could condense on the underside of the boards.

–    And whilst it won’t create condensation, we don’t recommend compressing your insulation as this reduces its effectiveness by up to 50%.

From here, consider using our LoftZone StoreFloor for an award-winning, fully patented, loft boarding system that is specifically designed for installing flooring over the full depth of your insulation, and for providing sufficient airflow above the insulation and underneath the boards.

It’s the strongest raised loft boarding system available with the flexibility to hold up to 500kg per square metre due to its supports of industrial-grade recycled plastic! You will never have to worry about condensation in your loft again, knowing that your insulation is always protected and cared for.
