Sun, Wind, Rain and Snow: The Silent Roof Killers

Poor workmanship is quite often blamed for faulty roofs, with homeowners quick to blame the contractor as soon as a defect is identified. While contractors are rightfully blamed on a lot of occasions, many people also forget that roofs can fail because of the weather. Sun, wind, rain and snow each bring separate problems to roofs and this means that no matter where in the world you are located, your roof is always going to be susceptible to some sort of damage. You should consider contacting a roof contractor at the beginning of summer or winter storm season to inspect your roof for potential problem areas which could save you money down the line.

Admittedly, if you take the correct precautions whilst installing your roof the risks of the elements causing defects diminishes significantly. Speak with a a team like ABC Roofing. On a lot of cases they just can’t be helped though, as we take a look at how each of the four types of weather can damage a roof.

Sun

Most people associate roof deterioration with moisture and quickly dismiss the threat of the sun. Unfortunately, the UV rays that are directed from the sun are anything but harmless, although they tend to only cause damage to flat roofs. Asphalt is usually the material they affect, with the rays causing cracking and blistering in the material that can cause it to become detached from the structure.

Wind

It goes without saying that wind can affect any type of roof, although in this case it’s usually pitched roofs which are most affected. In severe cases, the shingles can become detached and while they may not be immediately blown off, they will most likely leave a small opening in the roof where moisture can penetrate. Fortunately, roofing shingles and supplies and quite inexpensive to purchase nowadays and if you can replace the tiles as they are damaged, rather in large quantities, it won’t be a huge job.

As well as the above, wind can have a direct effect on roofs. Branches from trees are commonly broken in strong gusts and if they come into contact with your roof, shingles can again be knocked off or your gutters can become clogged up with debris.

Rain

We were almost tempted to leave this element out, with rain regarded as such an obvious hindrance to roof. It’s attributed to the vast majority of roofing problems, with moisture ingress having the potential to wreak havoc if water manages to seep into the home.

Fortunately, unless your roof was poorly constructed or if one of the other issues that have been discussed in this article have compromised it, there shouldn’t be any areas where rain will be able to access the roof space.

Snow

In the UK, this isn’t a particularly prevalent problem. However, this is perhaps the reason why it is so dangerous – as homeowners simply don’t realise the threats it holds. Arguably the main concern is if the country receives a large quantity of snow, with this sitting on roofs and causing an unprecedented loading that the structure simply isn’t designed to withstand. Another issue can relate to the freeze-thaw reaction, with water tending to seep under the shingles and freeze durign the cold weather – causing the shingles to lift.
