Our tips & advice on leaky roofs
Although they are high up, roofs are noticeable. If yours looks like it is at the end of its life, it can send alarm signals to potential buyers...
It's one of the most expensive repairs a purchaser can be saddled with so it makes sense to make sure it's in good shape before putting a property on the market. Don't worry about scraping off moss or lichen. Some people think it looks unsightly but it doesn't actually damage the roof in any way. In fact, the cleaning process is more likely to cause roofing problems than leaving it well alone. If you're selling a property 80 or more years old and the roof is showing signs of age, mortgage surveyors very often play safe and make useful comments, such as ‘at some point this roof will need replacing'. Of course, this is true of every roof in the country but, written down in a survey, it may hold up the sale. Personally, I'd always reroof a tired roof in order to sell a property for a good price in a reasonable time, especially if you have nervous buyers.
Roof Warning Signs
1 Slipped, missing, cracked or broken slates or tiles: After a while nails rust and slates will tend to start slipping. You don't necessarily need a new roof as you can refit the fallen tiles/slates and hold in place with lead tingles/clips.
2 Worn lead flashing, soakers and valleys: These can wear thin and need replacing.
3 Worn pointing and flashing, especially around chimneys: This can be dangerous as the chimney will eventually collapse.
4 Sagging: This often occurs when slate is replaced with cheaper but heavier concrete or clay tiles and the original timbers are not strong enough to support them. The only solution to get the roof looking right again is to replace the whole structure including the timbers.
Remember there is always a reason for a roof to be leaking as the water has to get in from somewhere. However, water may travel a distance from the source of water penetration to where it appears on the inside, and so solving a leak can be timeconsuming and frustrating. Most slate and clay tile roofs leak very slightly anyway, but the water quickly evaporates. It only becomes a problem with very heavy downpours, where roof coverings are soaked for long periods of time and don't get chance to dry out. Most leaks occur because of cracked slates or tiles, or faults in the flashing. Once these have been located, they are relatively easy to repair. In most cases, there is no need to replace the whole roof.
