Walking on corrugated metal roof.

[MarlowStat]

Hey folks, just trying to figure out if you would think a roof like this could be walked on. I have a few minor repairs to do like changing out some of the roofing screws and seal up the ridge to stop debris coming in. The other option is a cherry picker but the cost of one to rent as well as trying to get access to the shed are a pain. Thanks for the help.

Looks a bit dodgy, placing a sheet plywood or similar on top first would be better though even then the purlins look pretty slender. Do you feel lucky?

Looking at it I'd say no personally.

I guess it depends on how thick the metal sheeting is and how much strength it has, but just from the pic it doesn't look like the roof is designed to be walked on.

Scaffold board along line of timber should be enough.

It looks like a fairly shallow, apex roof. The obvious thing to use is a roofing ladder, which will hook over the apex. Trouble is, it is so shallow, so I would add a rope lashing, from the top of the ladder, to a solid attachment, on the far side.

Yeah it is a pretty shallow roof. Sorry for my ignorance, but if I can’t walk on it, am I still able to use a roofing ladder? I know it’ll spread the weight a bit, it’s just something I have no knowledge of.

The ladder will transfer the load to the stronger apex, and eaves supports, if you keep your weight on the ladder. The roof, in between those places, looks quite weak.

Depends if .5 or .75mm sheets and how far between the timbers

You could certainly walk above the steels.

How much do you weigh? Got any light children or dainty women?

I had a house with a giant 'car port' that was very large. It had rigid plastic sheets supported by a very rusty metal framework.

I used to hire acrows and scaffold boards. Once supported etc it was fine to walk on.

The .5mm dents, when stood upon, the .75mm is not so bad, but the roof timber structure, does not look able to support the weight of an individual working upon it.

My car port structure was made of metal....

If the building was done professionally one would hope it was done to specs. The barns I've put up have 7x2 purlins 12ft long between the steels but when the sheets are stitched together, screwed down to timber with teks the load is distributed somewhat so for less demanding use/exposure may get away with smaller timber.
Hard to tell on op purlin spacing but generally specs are 1m to 1.2m max for for .5 sheets and 1.2m to 1.6m for .7 but must admit I only use .7 and space at 1m
You can get fillers to seal ends but you need to know the correct box profile section.
