Asphalt rolled roofing applied to plywood with roofing sealant does not work for me. even when I am careful to applied the sealant close to the edges of the plywood the rain seems to feed back and the plywood rots. What can I do different on my horizontal hives?

Sealing down the rolled roofing probably causes problems with moisture penetrating the ply from underneath. Heat from sun and moisture = rot . You might do better with shingles which can breathe.

rot is rot, a lid is a lid, things don't change if it's a long hive or a vertical hive
you don't see shingles/waterproof roofing on lang lids, but for some reason it happens from time to time with alt hives

Imo, there's a lot to be said for a telescopic cover - which then provides the equivalent of an all-round 'drip-edge' - assuming this could be incorporated into whatever style of hive you have. I've made dozens of these, mostly with aluminium sheet on top (ex. scrapped caravan (camper)), but also a handful using heavy-gauge PVC (ex. supermarket 'special offer' banners), which is far easier to work with - and which appear to be holding-up ok. I find that lifting the telescopic cover clear of the topmost box with 5-10mm blocks or battens is sufficient to allow any trapped moisture to escape.

As mentioned with aluminum, same can be done with tar-paper folded carefully to make the corners, so there are no cuts for water intrusion. You can form it to come down the sides and create an integral drip edge of sorts. The seal isn't 100% solid all the way down the sides, so presumably some moisture could escape from the sides. So far I've never had one rot, even though I usually make super cheap "migratory" type covers. I've also made a super pretty one with stainless flashing and cedar shake shingles that has held up beautifully, but after having to keep lifting that thing up and down all year I am starting to appreciate the very light migratory covers more

I used to use coroplast attached to a wooden frame. That worked ok, but eventually the areas where the coroplast was attached to the wood would rot due to the moisture that would get in there. That and they are so light that if any wind gets under them they blow off. And if you didn't get a good coating of paint UV would break it down quickly. But it was cheap. Now I have been using the plastic roofing panels with a slightly heavier frame. Still really light though. I still use some coroplast for nucs, but as they get really ratty I replace the lids.

I made the hive roof for my Warre out of a piece of PVC soffit trim.

Since I didn't use it all up on the Warre, I also made a flat telescoping cover for one of my Langstroths.

I glued it together using epoxy and pocket screws underneath. Its waterproof.

I don't know if that is what you were looking for, but its an idea.

Earlier this evening I was reading-up on the development of the Gallup/Adair Long Hive, back in 1872. One of the materials they used to make roofs back then was ... wait for it ... paper !

Not just any old paper, of course, but roofing paper if possible - but if not, then thick brown paper as used to make potato or flour sacks. This was pasted onto the wooden roof structure, then given two coats of paint (white lead in those days). As Adair pointed out, paper neither shrinks, swells, cracks nor warps. Four years later, and those paper covered roofs were "as perfect as when made.". Extraordinary.

That was back in the day when paper was paper!

Question about condensation on a indoor unit. So I was working on a unit the problem was water was leaking onto their roof. I checked the drain/drain pan and verified that it was working. I come to find out that air is blowing the condensation off the evaporator onto the plenum. What’s the solution?

Stevenvaughn, this is a beekeeping forum, and the thread is about a lid on beehives. Your post seems to be about an HVAC unit installed on a structure roof.

As this is your very first post, I have to wonder what you are up to. Post about beekeeping, please, otherwise your time at Beesource may be quite limited.

Would a Gable Roof work?

 

[viesest]

I think that roof should be flat. The frame should be plastic, inner part wooden and cover metal sheet.

Btw.
Houses also can have flat roof when metal sheets are used. (Reasons: less wood needed, storey instead of attic, better for solar panels).

Maybe aluminum drip edge flashing would work for you.
