I have a metal roof with a 5 degree pitch in a temperate climate (snowed once in 50 years). My living room equatorial facing Windows are largely blocked by my neighbors but I do get some sunlight coming thru clerestory Windows.
I'd like more sunlight and the roof itself receives unobstructed sunlight. I did talk to the solatube rep but he said they couldn't help me squeeze a tube between rafters etc. And the light from those is pretty weak.
So I guess I'm looking at possibly a skylight or similar so I can get the sun in, with the aim of keeping alive some of my frost sensitive plants over winter.
But a structure in the middle of my roof is going to stop water draining unless I guess it gets diverted around the skylight without pooling.
Would it be a bad idea? Alternatives? And I'd rather not lose any heat in winter.
