TT Roof Strength

Use small piece of Masonite to walk on, disperse the weight as you walk and it is smooth unlike plywood.

A really nice type of sheeting to use on the roof is a piece of 1" (+) extruded foam board. It will support your weight and is comfortable to kneel on.

What painters planks are for. 2 suitable height step ladders and a painters plank between the ladders. You can rent a suitable length plank at any rental place, by the day, week or month and they are very reasonable.

I have the same roof issue and that is how I overcome it.

I've been walking all over my non-walkable roof this weekend as I prep it for a fresh rubber coating. I just make a point of looking for the joists and spreading my weight. I think a board to distribute the weight while working on the AC would be just fine.

I like Westend's suggestion. Light, comfy...

A painters plank is the safest. No chance of damaging a non walkable roof.

With any contact overlay, you have no idea how much it can support without failure. Why take the chance. Seems pretty cut and dried to me. Maunfacturer says roof is non walkable. What they mean whether you spread the weight out or not, it's still weight in the excess of what the roof was built to carry.

I know my unit specifically states what the maximum allowable weight is in my owners manual and getting physically on the roof, exceeds that weight.

Does it ever sit out in the snow?!

Well, I won't be walking on it. I am going to just sit on the edge so I can reach the cap cover on the AC. Thanks everyone for the advice.

Mine? Never. Mine stays inside all winter. Actually the only time mine is outside is when I'm using it... Amazing how that works and preserves the roof and other parts too.

Far as snow load goes, snow load is not as concentrated in a small area as is size 10's walking around up there.

AC unit is all fixed, without walking on the roof. Now the wife can't complain because it's too hot. ;-) Well, that isn't fair, I do complain too.
