If you suspect your roof is leaking or needs repair, it’s important to get the problem assessed by a professional roofer and fix it as quickly as possible. If repairs are nit undertaken quickly, the damage caused by water can dramatically increase overall roof repair costs. Structural timbers in the property can be weakened if they’re continually holding water. Saturated brickwork and masonry can also often cause internal damp problems that can result in the need for extensive internal aesthetic work too.
