Blocked gutters and downpipes can cause a variety of issues.

If left untreated, the water that accumulates in the gutters and downpipes can cause the gutters to overflow, possibly leading to flooding of the roof and surrounding areas.

Water backing up in the gutters and downpipes can also cause the gutters to pull away from the house and cause damage to the fascia boards.

This can lead to other problems, such as the rainwater not being able to escape the roof and allowing moisture to seep into the house.

Blocked gutters and downpipes can also cause structural damage to the roof if the weight of the water becomes too great and causes the roof to sag or collapse.

In addition, if the water is left standing for long periods, it can lead to the growth of mould and mildew, which can cause health problems.

Finally, blocked gutters and downpipes can attract pests such as mosquitoes and rats, which can also pose a health risk.

To ensure that these issues do not occur, it is essential to have regular gutter and downpipe cleaning to keep them free of debris and ensure they are functioning properly.
