In the UK, we’re at the constant mercy of a highly unpredictable and temperamental climate. The temperature changes that occur from season to season are often extreme, and, as we’ve all probably experienced, it’s not uncommon for freezing-cold rain to give way to bright sunshine in a matter of hours! These fluctuations in heat and moisture can have a negative effect on all areas of a building, not least its roof. The type of issues caused by the climate (and, indeed, other factors like inadequate installation) are nothing that an expert roofer cannot fix, but it is always advisable to stay on top of any damage as soon as it occurs. So, with this in mind, here are five common roofing issues to be aware of in the UK.
We all know that poor ventilation within the home can lead to excess moisture, causing damp, mould and mildew. Well, it’s the same with the roof. A lack of airflow in the roof can, in the long run, cause damage to roofing shingles and timber framing. It could be simply due to an object blocking the vents, or, more seriously, the vents being in the wrong place.
Shrinkage and blistering
When the membrane underneath your roof tiles or shingles shrinks (due to heat and light), this can cause the shingles or tiles to crack. They can also blister because of intense heat. In extreme cases, this can cause the roofing materials to deteriorate and weaken over time.
Moss, algae and other forms of plant life can cause a surprising amount of damage if allowed to build up over time – getting between roofing materials and making space for unwanted moisture. Of course, some homeowners like the idea of creating a rooftop garden with plenty of vegetation, but the roof needs to be protected with a watertight seal first.
Poorly installed flashing
Roof flashing is a waterproof sealant that protects the joints of the roof from rainwater and other forms of moisture. If not properly installed by a professional roofer, it can leave the roof vulnerable to leaks or cause damp patches on the ceiling.
Ponding is essentially an accumulation of water on your roof, over a number of days, caused by blocked guttering and downpipes, or a roof edge that has been constructed incorrectly. These ponds can turn stagnant and cause a build-up of debris, or lead to leaks and damp patches.
