What causes timber fascia to rot
Leaking guttering is a common cause of timber fascia rot. When gutters are not properly maintained or are clogged with debris, water can overflow and seep into the fascia boards. This constant exposure to moisture can lead to rot and decay in the timber fascia. Here are some reasons why leaking guttering can cause timber fascia rot:
