What's the benefit to using metal tops?

[SgtMaj]

What is the specific benefit to using tin or aluminum on the tops?  Is it just for weatherproofing?  If so, then wouldn't creating an angled top with no metal work just as well?

I don't see any benefit, good paint every couple or three years is better.
Metal can and does cause condensation to build inside the hive, if you end up having poor ventilation.

I'd wager if the top were angled so that dew or rain would run off, it would last even longer than that with the original coats of varnish.

   You can use garden covers!  :?  I use exterior plywood (no tin) and a good  coat of paint on telescoping covers.  Exterior plywood last  me for about 15 to 20 years!

     And this is in New England whether

It is all about longevity.  Some of my equipment is well over 30 years old.   The reason they are flat is for storage.  When you have hundreds of hives, you can easily store flat ones by stacking them.  It's not so easy to store pitched tops, not to mention the actual cost and extra time to build pitched tops.  You can also stack hives for shipment with flat tops.  Also when you have a lot of hives,  rotating them off and the time to paint them is not practical.  If your a hobbyist,  you have the time and can do whatever you like.

My roof shouldn't cost any more than a flat roof (and actually less since no tin)... and shouldn't take any more time.  I'll take pics when I build.

if you do a single pitch like a shed roof you'll manage the stackability and the water runoff,
you just have to make sure to stack it carefully or it becomes a serious hazzard

What do you mean?  Why would it be a hazzard?
