Thank you, it's a flat roofing section I need repairing - would triflex or torch on felt be more appropriate for a 1.5 x 1.5 meter section of flat roof?
Those waterproof roof coatings work, was used on a temporary repair on a really poor roof till funding was in place. So far lasted five years and the funding isn't in place.
EDIT: Thompson roof seal, the 10 year guarantee one.
I know a little but my knowledge is limited to certain flat roofing systems (mainly grp, torch-on felt and EDPM).
