Walking on/across metal roofing

I'm frequently walking over/across my current shingle roof to make repairs, clean out gutters, paint, etc. Is walking over metal roofing more difficult - is it more slippery? esp. when wet? and is walking over a metal roof likely to cause any damage?

Most metal roof systems will have "walking" instructions available. By following some simple instructions, you can walk on these roofs safely and without damage. Most any roofing material can be slippery when wet so I'd avoid walking on wet roofs regardless. Metal roofing has the advantage of being maintenance-free so, oftentimes, you'll find that, after having metal installed, you will have less reason to wlak on the roof. Some homeowners choose the re-roofing time as a time to make other parts of the home maintenance-free as well by installing metal soffit, fascia, etc. That can eliminate the need for future painting. One BIG benefit to metal roofing in terms of walkability is that it retains its impact resistance as it ages. Whereas many other roofing materials, after they age a few years, can be damaged by walking on them, that is not the case with metal. It will resist foot traffic, hail, etc., the same in 50 years or more as it does when it is new.

what about installation, i would like to hear what are some precautions dealing with moisture. I have to go to the bottom and screw in final touches.

Follow the building code and product approval report. Generally speaking you are required to install a moisture barrier (underlayment) under any roof covering with 15 lb felt being the minimum. Extra eave protection is alos required in severe weather areas. All roofs also require a drip edge at the eavs, Just terminating sheet steel is not enough as wind will suck the water up and around the edge. Best buy a formed drip edge and use butyl tape to seal it to the metal roof sheets or a foam closure strip. Most important is to ensure the roof assembly is adequately ventilated. Attics are 1/150sf of ceiling area dn provided equally at the ridge and eave. Vaulted ceilings are a minimum of 1" of vented free air space under thr roof covering. Vented closure strip is a good way to provide this.
