February 25, 20242 yr Extended the garage about 20 years ago (5.5m by 3.5m) matched the original pitched roof (Marley Mendip concrete tiles and roofing caps) - been absolutely fine for years No leaks into the garage loft space but I noticed the other day when cleaning out the gutters some of the mortar on the valley joints and the roofing caps has cracked - some has fallen out and dropped into the gutters (see other post on gutter cleaning Anyone know what mortar mix to use if I get up there and pull out the loose stuff and re-point/repair the areas where it's poor? Soft sand or Sharp sand? I'm quite happy working/walking on a roof - it's only single storey and I over speced the roof trusses because I use the loft garage for storage
May 22, 20242 yr Not sure of you're still interested, but maybe useful for future readers. I'm not a roofer nor have I built a roof (yet!), but reading about tiled roofs as much as I cam I came across this great website with lots of articles on pitched roofing with expert advice. Regarding roofing mortar mix: https://www.roofconsult.co.uk/articles/tiling/tips43.htm It recommends 1:3 cement:sand. The sand portion to be half soft sand (i.e building sand) and half sharp sand. Their list of tiling and slating articles: https://www.roofconsult.co.uk/articles/tiling/default.htm
