A cracked roof tile can seem like a minor annoyance, particularly when there is no obvious leak inside the house. A slipped tile may look like something that can wait until the weekend. Yet the roof is a system where one small weakness can leave the layers beneath exposed to rain, wind and frost.
Knowing what causes these problems, and how quickly they can worsen, can help you decide when it is time to call a roofing company in Woking rather than hoping the weather stays kind.
Why do roof tiles crack?
Age is one of the most common factors. As tiles spend years outside, repeated exposure to sun, rain and freezing temperatures can gradually weaken the material. Water can enter tiny imperfections, freeze during colder weather and expand, putting additional pressure on the tile.
Impact can cause more immediate damage. A falling branch, storm debris or even accidental damage during nearby maintenance work may crack a tile. Sometimes the damage is obvious; sometimes a hairline crack is difficult to spot.
There is also the possibility of movement within the roof itself. Natural building movement, ageing fixings or deterioration around supporting areas can alter how individual tiles sit.
What causes roof tiles to slip?
Strong winds are an obvious culprit, particularly where tiles or their fixings have already weakened. Repeated exposure to gusts can gradually loosen tiles until they move out of position.
However, wind is not always the original cause. Old or damaged fixings, deteriorating mortar and movement beneath the tiles can contribute too. If one tile slips, it can leave a gap through which rainwater can enter.
The problem may become more noticeable after severe weather. You might see a tile sitting lower than its neighbours, notice a gap in the roof covering or spot pieces of broken material in a gutter or on the ground.
How serious is a cracked or slipped tile?
This depends on the extent and location of the damage, but it should never be dismissed automatically.
A damaged tile can allow water to reach the underlay, battens and other parts of the roof that are designed to remain protected. Initially, the only sign may be a small damp patch in the loft. Over time, persistent moisture can contribute to timber deterioration, mould and damage to insulation.
There is another concern: one damaged tile can leave nearby areas more exposed. Wind-driven rain can find its way beneath the surrounding tiles, while loose tiles may shift further during the next bout of bad weather.
When should you arrange a professional inspection?
If a tile has visibly slipped, cracked or disappeared, getting the roof assessed by an experienced roofing company in Woking is the sensible move. The same applies if you have noticed water marks in the loft, damp patches on ceilings or unusual debris collecting around the guttering.
Avoid climbing onto the roof to inspect the damage yourself. Roof surfaces can be slippery, unstable and difficult to navigate safely, especially after rain.
A professional assessment can establish whether the issue is limited to one tile or whether there is a wider problem involving fixings, mortar, roof movement or surrounding areas.
