    What Causes Damage to a Roof?

    The main causes for unexpected damage to a roof will happen during a storm. Heavy winds and driving rain can sometimes or damage tiles that have become loose over time. Larger items can also be lifted by the winds and land on the roof causing unexpected damage.

    During colder winters, have large snowfall can cause tiles to crack, both under the weight of the snow on the roof, but also when the snow begins to thaw and then freeze again later in the day, expanding into smaller cracks and making them larger over time.

    Another common cause of damage is by animals that decide to nest in or around your roof and sometimes enter through the eves. Birds and insect nests are the main cause of this damage and you will need qualified pest control to remove them.

    You’ll need to have the right protective gear to stop you or your equipment falling from the roof. This is one of the main reasons you should always hire a professional to clean your roof.
