After the heavy rain on Friday night I went up into my loft and to my horror, found that the rain has seeped into the whole of the roof space. All the felt is soaked with the rain dripping through the felt onto the loft insulation, and the rafters and joists are wet. The tiles look like concrete/clay and presumably have become porous. The house was built in 1964. Last summer a number of houses in the area has their roofs cleaned and spray sealed by a roof sealing company. I can't afford to have the house retiled so my questions are as follows:
1. Does this roof sealing (cleaning and spray coating) work
2. Any ideas roughly how much a 3 bed semi roof would cost to be treated
3. Am I correct in thinking that the problem is porous roof tiles.
