Repairs, new roofs and guttering across Harold's Cross

Many Harold's Cross terraces have valley (butterfly) roofs hidden behind the front parapet, shared chimney stacks and tight rear access, so experience with older city roofs matters. We repair and replace natural slate, clear and re-line valleys, renew lead flashing, and fix the rear returns and extensions where leaks often start.
