Have you allowed to build up on your rig before climbing up and clearing it off? Got real worried with 18+ inches of Sierra cement and finally did it. Wasn't easy but what a relief!

Way back when, I had a Newmar fifth that stayed north during the winter. We had some big snows that left near 4 foot of snow on the roof. Called Newmar and talked to one of their engineers who advised that that quantity would not be a problem except for the roof vents, particularly when melting started.
Went out and shoveled the roof and felt tired but better.
Now, being retired, i've found that it very rarely snows here in Florida.

Might not be an easy answer to find but knowing what the designed live load of the roof would give a person an idea how many pounds per square foot the roof could take. 1 cubic foot of water weighs approx. 62 pounds. So, wet snow versus powder would also make a huge difference.

Mine along with a couple hundred other rigs sits in a yard all winter. No one comes and cleans them off.

Never seen a rig flattened yet due to regular snow loads including up along Lake Huron where we kept our camper for a few years.

I have always thought this way -

ALL those dealers in NW NY State where the lake effect snows get turned on, or anywhere with heavy snow fall for that matter.. NONE get on and clean the roof that I know of...

Since I am still somewhat young, I will use a rubber squeegee if the snow pack gets DEEP.... just to clean off the outter 2' or 3' to allow the water to escape

I always am more concerned with the re freeze and thawing causing water to run into places it usually wouldn't..

Done that once or twice over the years is all....

One of my buddies parked his motorhome under a metal carport cover. Unfortunately, the cover wasn't rated for much of a snow load, it collapsed and crushed the roof of his motorhome. A case where it would have been better to be uncovered than covered.

Adverage 1inch liquid equals 10" of snow so super daves wt per cu ft 120" for every 10 sq ft at 1 inch of snow on your roof equals 64lbs. or for my rig 1920lbs for every inch of the white stuff.

This is one of the reasons I pony up and pay for indoor storage for the fiver and boat for the winter. That plus the freeze/thaw cycles and the massive amount of rain we get here on the wet coast. I love how they come out in the spring looking exactly as they went in the fall! [emoticon]

Snow load design for RVs is a good question. Houses are built different ways depending on where they are due to anticipated snowfall but since an RV has wheels, no one knows where it will be. Realistically, the roof span is pretty small so it's not hard to just over-build them. Of course, over-build is not a term typically associated with RVs so who knows? Good question though.
