hello, i have a 1960's house with a shallow pitch tiled roof. the tiles are large flat Marley tiles. the valleys are tiled as well and we seem to have developed a leak somewhere with water ending up inside. what is the best roof paint to use in this situation, please? i have looked at a few on your website, but wasn't sure which product would be best as the roof would naturally move a bit where it is tiled. we need a temporary fix as we will be re-roofing in the next 2-3 years as part of a major house renovation. can you help please? my mobile number is 07584408986 if you would rather call to discuss.
