If you notice mould or water stains on the walls inside your attic, you might assume that the roof has sprung a leak.
However, poor ventilation could be to blame. It would be good practice to look for the following signs of poor ventilation in the house — especially as rectifying the problem can be much more straightforward than you might expect.
Mould
Ventilation removes warm, humid air from the attic and brings in fresh, cooler air to prevent moisture buildup, which can lead to mould growth on dampened surfaces like walls or ceilings.
Water Stains
Water stains are named as such because they are caused by moisture. Though it is easy to mistake a water stain for mould, the former first emerges as a small black patch. If you allow this staining to spread, you could end up needing to get the entire roof replaced.
Loose Tiles
Go to a safe vantage point where you can inspect the roof for loose tiles. You could simply walk across the road from your house.
Regardless of the method you use to check the roof, remember that moisture in the attic can cause the wooden decking of the roof to separate, reducing its adhesive strength and possibly causing tiles to slide off.
If only a few tiles have become detached from the roof, something else — such as a recent bout of harsh weather — could be to blame. If large areas of the roof are showing loose tiles, you might want to start researching a range of roof ventilation options.
