This homeowner is my hero.....installing a new metal (galvalume) roof....over his existing shingles. I was on my way to a job site and saw what was happening so stopped and had a brief chat with him. This is exactly what I'm planning to do for my roof next fall/winter.
There are plenty of venders who will supply metal panels at whatever size(s), quantities, and color, you need.....delivered to your door step.
Pull the permit yourself as the homeowner.
He used 1x4's as furring strips - screwed into the joists with 3" deck screws. Then attach the metal panels using appropriate fasteners.
My situation is similar to this fellows.....single story with relatively low sloping roof...except mine's a simple gable and his is a hip roof. My roof is 100% symmetrical like a piece of notebook paper folded down the center - and that's it.
Total cost for materials should end up approx. $3K at the most. I could probably do it all myself but I will rustle up a helper. I built a 12'x30' shelter using these panels myself last year...no biggie if you have the tools and time.
Anyway.....here's the pic I took of his house and the project well underway....
