If condensation is a regular occurrence in your roof space, the first step would be to check your current insulation and where the areas of concern are. We advise that you contact Warm Lofts Insulation immediately so one of our experts can assess your loft.
If left without attention major costly repairs or damages could occur.
The most common causes of condensation are:

  • Cold weather finding it's way into your  property. Poor insulation  would cause this.

  •  Changes between warm and cold weather. (Climate Change)

  • Larger temperature drops between day and night

  • The main cause is where Hot air in your property meets cold air coming into your property, generally through your roof. This tends to cause huge problems, leading to damp and mould. If not treated or looked at quickly it can also rot your timbers and structural support to your roof. 

  • If you have no felt/membrane in place in between your rafters. This allows too much cold air in and is a cause of concern. Check that the roof tiles are not visible as we advise a membrane in place just to keep as much of the cold air out as possible.

Condensation in roof spaces are temporary if treated quick and effectively. Water vapour can pass through most buildings. As the traditional use of insulating a loft is fibre glass, conensation will cause a problem and cause fibreglass to shrink and rot over time which can then lead to damp patches on your ceilings and a need to re insulate which again is costly.

How condensation gets into your roof

Spray foam insulation is a great way to deal with condensation. It will stop the water vapour from getting into your loft space and it also makes an airtight seal which prevents any moist, warm air entering through your ceiling where condensation can form again.

- Spray foam insulation is a good solution for condensation in roof spaces because the chemical we use is open-cell which is breathable and pushes condensation to the dew point, above the roof.

Condensation in roof spaces can cause problems for homeowners, including mould growth and condensate dripping from the ceiling. The best way to prevent condensation is with spray foam insulation. Spray foam insulation does not allow water vapour to pass through it, so condensation will never form on its surface. Loft insulation also helps keep condensation out of your home's roof space by eliminating cold spots that lead to water vapours collecting on ceilings.
