Keith, if the "Alan" referred to by Eddy is Alan Graham of Renowned Roofing I'll endorse his recommendation 100%. Alan was first recommended to me by a local builder over 20 years ago. He's the man local builders use. Fair fast and reliable and a thoroughly nice gang of lads.... wish there were more like them.
