I noticed belatedly a slate had fallen off my roof. Ray pointed out it was two slates. The repair could have been a lot more expensive with scaffolding, but he tried it with a long ladder he had just acquired, and was successful. He saved me a lot of money because in seeing what needed to be done, he also took into account my needs. I was very impressed by his professionalism (he arrived on time to survey and notified me of changes); the repair was quickly done; and in discussion he conveyed to me, pleasantly and effectively, the issues involved. As a consequence, I trust his expertise, and will use him again.
