A Complete Guide to Damp & Damaged Roofs

Posted on by Protech Roofing Team

With the wettest January on record, and thousands of gallons of rain hitting our roofs each year, it is hardly surprising that damp is one of the main causes of roof damage. If left untreated, damp and the ingress of water can have devastating effects on both the health of occupants in a building and to the structure of the building itself.

The best thing to do is have a yearly inspection by a professional to ensure that you protect both the staff and customers in your building, as well as any equipment or assets you have therein.

Spotting signs of damp

Often, damp is referred to as a hidden menace because it isn’t always easy to spot within a building. It could be lurking high up in your rafters or resting in your cavity walls, and before long the effects could be irreversible. The first thing to take note of is the smell; this is likely to be the first sign that you have damp damage in and around your roof. The fusty smell is unmistakable and shouldn’t be ignored.

Other signs include markings on your walls which look like tide lines, actual damp patches on the underside of your roof and on your walls, damp timber or even mould in the corners or edges of your attic space. The sooner you spot these signs the more chance you have of stopping or repairing the damage, but most of the time damp will have been working its way into your building long before you spot it.

Solutions for tackling damp

Although you might feel panicked at first you should never rush up onto your roof to start with any DIY. First get an assessment by a professional roofing company and find out just exactly what kind of damage the damp caused and how far spread it is. The experts will then make recommendations on the best action to take regardless of whether you have a flat roof, a metal roof or a green roof.

The recommendations could be extreme – the removal of the roof entirely, for example – or as simple as having some tiles or flashing replaced. Clearly you will want to minimise the amount of downtime your business sees so the old idiom of “prevention is better than cure” stands to reason here.

Improving the ventilation in your building can be a massive boost to preventing damp. Many buildings are sealed up tight to save energy nowadays, but this can have a negative impact if moisture gets in and has no means of escaping. There are also plenty of anti-mould products on the market to help shore up your roof and protect you from the damaging effects. One extra way to see that water doesn’t pool, settle or seep into your roof is to check your guttering and drainpipes. This way you can ensure the majority of snow and rain is being diverted away from your roof.

In addition to these measures it is always recommended that you seek professional help when you suspect that damp has affected your roof.
