In a heavy down pour the roof leaked in my 4106 in about 5 places. I am about to put the plywood on the ceiling. The bus had 4 ft of snow melt off it this winter and it never leaked. I can't see where the water is getting in, the roof looks just like it always did. What should I look for? What shall I do?

I suggest you get a garden hose and an assistant to help you trace down any leaks. You don't want to ruin your new ceiling, do you?
Once you find the leaks, the best stuff I have found for sealing roof leaks is polyurethane window, door and siding sealant, the stuff I get at Home Depot is made by "PL". It is sticky, gooey, requires mineral spirits to clean up afterwords (wear disposable gloves) and takes a week to cure, but once it does it dries it lasts for years.

You have "Snow" and your not spraying the roof??? You have aluminium (unstable material) joined to aluminium buy aluminium? Condensation is going to be your constant companion.
I think Geoff's suggestion is good because it "migrates" and fills cracks but, I would spray every exposed thermal conductor with foam. Waite till the wife is cooking spagetti and your kids have taken two showers can you hear the hair dryers........plan ahead!

"I suggest you get a garden hose " Sometimes a hose-type stream doesn't work as well as a sprinkler, rain-like, don't really know why, or care, but have found many a roof leak with a sprinkler that got missed using a hose. FWIW

I had a leak that did not show up until the ceiling was taken down. RTS buses use fiberglas ceiling material so water does not affect it but allows it to move to another part of the bus.
As I was working on the roof, when I was near an area that I saw water marks on the ceiling, I looked around. RTS buses have the roof, made of sheet stainless, spot welded to the frames, and the vibration and such of the bus in service causes the spot weld to rip away from the frame, sometimes leaving a crack in the sheet stainless. The bus company would weld it back for repairs but as I can't weld metal, it was suggested to use Kool Seal on the roof, which I did. This accomplished two things, it stopped all leaks, both found and not, and you won't believe how cool the interior now stays in the summer (The bright white color reflects the heat away from the metal). Used koolseal on an RV and had the same affects, and it lasted the life of the RV. Great Stuff, would recommend it to anyone, just use it for the right purpose.

When it warms up around here (20 last night snowing now) I'll get out that sprinkler. Kool Seal sounds good. Thanks, John |

John
A little hint, if there are any areas that flex or have any kind of movement, they have a cloth that you Kool Seal it to the area in question.
When I used it, there was only one type of Kool Seal that you could buy, now there are several, I recommend getting the commercial type. I bought it at Camping World if you are looking for a place to find it.
When the cloth that you soaked with KoolSeal(with a paint brush)cures, give it another coat, let dry and if the cloth still looks porus, give it another coat. I think it will cover well in 3 coats on the cloth, the edges should look like it is part of the roof coating when done. They also do this around anything that sticks out of the roof, vents, skylights, etc. I did this to an RV and it never again had a leak, not never. The cloth looks kinda like a cheese cloth and does a good job. and as I said, wait till you see the difference in the inside temp. Good luck q |

No Johm, I have used Kool Seal too with great results. It is sold at Camping World under the Kool Seal name, look under the name and it will say Commercial formula. The difference in the regular and Commercial is the Regular is really fluid, not quite like water but close, the Commercial type is thicker, like a thick paint and is easier to apply.
Good luck cd |
