Steve helped provide some great advice on a flat roof condensation problem, I followed him on Youtube and thankfully he was willing to provide some free advice that really helped my situation with my garage build as both my builder and I were a little stuck to why we had wet patches internally on our roof. Steve replied at 7am in the morning after I email him at 10pm the night before. I have no doubt that his level of work is great based on my time (hours) watching his videos online. Thanks Steve.
