I am starting a top bar hive this year in addition to the langstroths I have and I've been doing a little bit of reading and web surfing but I wanted to ask the good folks of BeeSource what your opinions are. Have any of you kept TBHs on a second story rooftop before? What do you do to keep swarming to a minimum if at all?
Two things come to mind about preventing the swarming.
1) Do splits as needed to keep the population appropriate to the space.
2) Never even seen a TBH in person but I've read that some can be supered with Langstroth supers. Making sure the bees have space to draw comb and store nectar can help to prevent swarming too.
Build it 48" and use a follower board to expand the space as necessary. If they fill up a 48", then build another and split the first. Repeat as necessary. Phil Chandler's website http://biobees.com is a good place to start.
What is the roofing material? Roof tops can get very hot and heat and bees wax are not friends. You may need to consider placing it on a stand that is 3 or so feet above the actual roof to get it up so the air can ventilate it well.
The roof here is tarred but painted silver to deflect heat. I was thinking of keeping the tbh lower to the ground to prevent it from getting knocked over by wind. Thoughts?
Oh, also my TBH didnt come with follower boards. I am having a hard time finding out whether these are totally necessary or not. Can anyone give me their opinion?
I can assure you as a previous roofing contractor for ten years, that roof will still get too hot even if its silver. I would make sure you put some sort of shade over your hives to help keep the heat from the real hot days to a minimum. At least paint them white.
I would place them close to the stairwell towards NE if possible, giving them as much shaddow as possible during mid-day, while heating them up in the morning.
I would also secure it by using wire, or build a solid stand with a wide and/or heavy sole that will not tip over easily in the wind.
The heat is going to be an issue, especially for the TBH as they are prone to damaged comb even without excess heat from a roof top.
Shade will be a must. If you want to keep them low to the roof, you might be able to get away with laying down some pallets and placing a sheet of plywood painted white to place the hive on.
Weren't you that tap dancing kid in the bee costume once? You know, the one from the 'Blind Melon' video? :lookout:
We put the TBHs on wooden palettes, but we will have them up on some cinder blocks soon enough.
I wouldn't lug cinderblocks around on 'tar beach' if I were you. If an edge cuts through the asphalt/mineral roll material, someone will get a leak when it rains.
