Want to know what, if anything, I should do about the roof job on my new extension- roof just finished, scaffold still up... From the pics it's obvious the cosmetic finish is not the best, mortar smeared pretty rough. And aside from no dye being used in the mortar mix there is some pretty large voids filled with mortar,mainly to fill in large gaps between the ridge and hip tiles. Does the job look otherwise sound or should I take issue with builder over the work? Not had any problems so far with the builder. I've worked in trades myself so I know perfection is rarely possible but value opinions on this please.
