Solar roof on E. Coast-Ice damming a problem!
I live in Long Island, NY with a new solar roof. Tesla has a problem with roof designs where the snow doesn't fall off roof freely and (TeslaSolarRoof)contributes to ice damming due to the build up of the snow and no clear way for the snow to melt and prevent damming.
Before my roof was done never experienced ice damming(over 20yrs owning home), because the snow never accumulated on that part of the roof. The snow slides down the glass from top to base and accumulates, because the snow volume is excessive and no functional way for the snow to fall off without alot of help. (This part of my roof involves a roof ridge & valley-Also a chimney)
The issue is to either provide a warming element at the base of the roof or invest in means to remove the snow manually(roof rake, blower, luck). I didn't account for the ice-damning when this process started and I'm not sure Tesla is aware of the problem due to the fact the roof was originally released in Ca, and they typically don't get snow on their roofs. Here on the east coast it has to be factored into the overall project especially if there's factors:
-design of roof
-ambient temperature of your town/village
-roof too high
-can the roof maintain it's purpose with days of ice-damming
-how do you anticipate the snow in the design of your roof?
This is just a note for people who gets snow either occasional or alot and have issue with ice-damming or WILL have issue with snow build up on the roof...considering the solar roof.
Overall I don't see it as a problem if you're prepared for it...There are a few days I'm concerned for my roof, gutters, and house due to the ice-damm not going away. It sits precariously close to the edge and until it rains or there's a very warm day to melt the excess snow & ice off the roof it's going to STAY there...I've ordered a roof rake and hopefully it will do the job of helping the snow OFF the roof when shoveling the snow.
But if I had known: Tesla would have had to plan this scenario into the design. It's dangerous - there's alot of factors that make it dangerous (ice pikes, water leaking into your home, never knowing when the snow is going to fall, gutter can break off and break windows), you(the owner) trying all manner of creativity to get rid of the ice & snow).
I mean who's as tall as their roofs?
