please advise: using flexacryl to fix leaky roof skews...??
hi
this is about a 1920s brick-built flat with slate roof. the whole building comprises 4 flats, (two ground floor, two upper). the slate roof is divided (above the party wall) by a small wall with coping stones, sealed along the sides with cement "skews". recently rainwater has been leaking into both upper flats, affecting the corresponding rooms on either side of the party wall. this has been diagnosed by quotes from two different roofers as being a problem with the skews (i think the diagnosis was based on their sounding a bit hollow when tapped). the solution is to remove the old skews cementing, replace any slates that get broken along the way, and build it back up again. but one roofer has suggested a cheaper alternative would be to paint two or three coats of flexacryl. i'm worried in case this might be a false or short-term economy: what's the expert opinion about using flexacryl for this...? many thanks for your help! |

Can you define what are "cement skews". Using any type of brush on sealer is only a short term solution |

Sounds more like a job for proper lead flashing.

If its raining in on an abutment wall, its usually soaker's and flashing wants re newing. The other cause might be the joints between the copings need re pointing. What I cant understand is theses "cement skews" ?. |
