Roof damage from condensation is typical during winters when warm interiors and cool exteriors cause excess moisture to form on the ceiling. It can be caused by improper loft insulation, inadequate vents, etc. When left unchecked, it can lead to severe structural damage and hamper the overall value of the house.
In the following post, let’s take a look at how condensation causes roof damage and how you can deal with it to avoid expensive repair bills.
How Condensation Leads to Roof Damage
Roof condensation happens primarily due to a temperature difference between the inside and outside air. As warm air in the house rises, it meets the cold roof and immediately condenses into water inside the roof. Since the moisture has no place to go, it gets absorbed into the roofing materials and causes a ton of problems, including mould and mildew, insects, rot, etc.
Unfortunately, damage from roof condensation is not limited to the attic area only. Instead, the damage can occur throughout the roof assembly and deteriorate the structural foundation. In houses in extremely cold areas with inadequate roof insulation, you may also notice ice dams forming due to the very same phenomena.
How to Deal with Roof Condensation
- Insulate your roof
Upgrading your loft insulation is one of the best ways to deal with roof condensation damage. Spray foam is an excellent insulator and prevents drastic temperature fluctuations on the roof, thereby reducing the amount of condensation that can form on the ceiling. You can get spray foam installed without major renovations, making them ideal for a wide range of situations.
- Improve attic venting
Improving the ventilation in the attic helps you address the problems associated with excessive heat and moisture that would otherwise cause severe damage to the roof. Achieving good attic ventilation has other benefits too, including lower energy bills, lesser chance of mould and moisture damage, etc. However, balancing the roof and attic ventilation is tricky and the job is best left to the professionals.
- Install a dehumidifier
In certain cases, a dehumidifier can be an affordable yet effective solution against roof condensation damage. These devices pull out excess moisture from the attic, thereby preventing water damage.
