No BS...Walking on Roof

[MONTE1214]

- I have an '07 Cruiser 27RL and need to get up to clean the roof.

- I'm 6' and 240lbs.



- Do I have to ensure I stay on the "trusses" or is it safe to walk all over?



- I've been up before, but only at the top of the ladder.



- All help is greatly appreciated!

I always try to stay on the trusses as much as possblewhen I am walking on the roof. When I don't I can feel it sag a little under me. I honestly do not know what the weight rating is for the roofing. I weigh about 170lbs.

Monte, I am 6'3" and 240 lbs and I am up on the roof at least two times a year for the past 5 years. Have never had a problem, yes you will feel more flex between the trusses, but the roof decking is more than adequate at 16" centers. BTW, the roofs on the cruisers and PP are framed the same.

I'm on my hands & knees for all my work up on the roof. I'm no lightweight and the roof didn't appear to give or sage at all.

Monte:
Ditto with the rest I'm 6' and about 210lbs I'm not particular about where I step when I am up there cleaning.I do try to pay attention other times when I am up there moving around cause it does flex a bit.

I don't "step" on the roof, I crawl on all 4. I am 6'3" and husky there is NO WAY I'm stepping on that roof.

I'm a small and declining 229 and 6 4" and I walk on ours. I try to watch where I stand and I walk light, Never had any issues.

- Thanks for all the help everyone!

- Like I said, I've been up there, and when I felt the sag...your stomach starts to twingeandyou can't help thinking about "going through".



- I like the "hands and knees" option. Maybe that'll be the way I go.Edited by: MONTE1214

I get up on mine too about the same weight as everyone else but I also want to point out I walk with socks on or make EXTRA sure you do not have any small rocks or something on the sole of the shoe that can put a hole in it. Yep walking to the inspection and maybe some sealing if needed but washing ... it might be a little slippery ... I am on all fours ..With some knee pads

[delqcc]

Just keep in mind when you are on hands and knees that it is most likely the contact area is less, therefore psi and likelyhood of penetration would actually be greater. (knee caps and palms versus soles of shoes)

I'm 6' 230# walk on all 2 only careful around the A/C unit. Up and down more times than I care to remember in the last week installing Max Air II and bi-annual roof cleaning.

- So, am I the only one who's sphincter tigthens up when that roof flexes?

[Lloyd]

I can't say that I'm afraid I will fall through my roof, but it does concern me how much it gives when I walk around up there. All that flexing can't be to good on the seals and sealant.
We have owned numerous RVs and I don't remember any of them that the roof was that flexible in between the rafters.
That being said, I wish CR had used 1/2" for the decking up there rather than the 3/8".
Might even have eliminated some of the structural problems that's happening.

I will say my Cougar 5th wheel's roofdidn't flex nearly as much as my CR. It had 7/16 inch OSB and a curved roof instead of a completely flat roof like the CR.

[mwebber78]

I think part of the flex is from the roof trusses themselves. There have been a handful of members who have had roof truss replacements for collapsed/slipped trusses. My Sunnybrook didn't have this much flex either, hence me crawling around up there!

[Korbe & Diana]

This may not be the case here, but TJI truss joists for home construction are meant to flex.
