I have found that water is splashing into my conservatory by running down inside my cavity wall; that is down the actual cavity. What could be causing this, please? Roofing problem? Pointing problem? This only happens when we have severe wind & rain storms that are directly hitting this wall, which unfortunately almost faces our prevailing wind direction. I know some of my roof tiles are 'feathered' on the edge & had cavity wall insulation fitted about 10 years ago. Only noticing damage to décor inside the house in my daughter's bedroom.
