If your house is suffering from a leaky roof, it is probably time to get the experts in. roofing problems can be more extensive than they first appear, often with the issue not seen until the roof is partially stripped. It may be if the roof has been leaking for some time that it has damaged the wood work that would also need replacing.
If you are experiencing mould coming in above a window, it may actually be caused by overhanging or damaged tiles and can be rectified quite quickly. The main cost when it comes to roofing is actually the hiring of the equipment especially if you need to have scaffolding erected.
Before having any roofing work carried out, it is advised if possible to obtain a few different quotes and try and find reviews for the roofer or company to ensure you are going to get a quality repair.
