My experience with All-Bond has been mainly positive, with a few negatives. Their workmanship is fantastic and despite an incredibly old roof (flat and sloped) that that wasn't easy to replace, All-Bond's staff did not complain and worked overtime to get the job done.
Unfortunately, we did have a minor leak a year later but they were quick to respond and fix the problem the same day. My only criticism with this company would be how difficult it can be to get in touch with them (although being busy can be a good sign too!).
