So we all know the basic idea of black absorbs light creating heat, white reflects light.
I had a thought of reroofing my workshop to a white roof thinking it may help keep it cooler in the summer but i'd "lose out" in winter from solar heating. Not that it makes much difference when the roof is covered in a foot of snow. But i've been trying to read up on white vs black roofing and its been a myriad of opposing arguments all strewn in suggested science - the kinds where research would support specific claims but redoubt others - from both sides of the spectrum.
So my fellow readers, just your black and white thoughts, what color would you pick and why?

Functionally based on what you are looking for, definitely white. I don't recall your location, but if you are in northern latitudes (you mention snow, so duh) the sun angle is too low in the winter to get any significant radiative heat benefit, especially comparatively speaking to high sun angles in the summer which makes it super hot. Also, snow is a good insulator, so if it stays on the roof, good, and you also would not gain any radiative heat benefits of having a black roof at that point anyway.
Aesthetically... meh, personal taste to get the color coordination down with surrounding faces.

Minne-snowta. Yeah we get loads of snow and i'm not positive, but i think this state nearly holds the united states lowest (recorded) temperature record.
EDIT: "Minnesota, -60F on Feb. 2, 1996 at Tower near Lake Vermilion" - fifth coldest state on abc7.com's list

Well if yer all talkin' braggin' rights, Syracuse is the snowiest city in the 50 United States with population of 50k or greater. Average annual snowfall is 120" (10 feet). I have lived through the 2nd, 3rd, and 4th snowiest winters of all time. The first year I moved here (year 2000) we got hit with 192" (16 feet) in one season. Welcome home eh.

I’d do white if the significant other would approve.

How about you alternate black and white so your roof looks like a checkered flag?
I wonder if you can get metal roofing polished and then coated with clear or just chromed.

*note to self* stay the hell outta Minnesota and Syracuse during winter.
On the roof question: just put a skylight in.
A friend of mine once had one in his 600sf shed. Well he called it a shed, but i called it a workshop. Thing was massive. He lived near Salt Lake City. Every summer he would go up and cover the skylight. He made a nice wooden cover for it. Winter, he would uncover it. At around 15ft high at the apex, it still got nice and warm inside.

I live just north of that recent superbowl us bank stadium about an hour's drive. That was probably the most comedy news we'd heard about the out of towners rental car catastrophes and other below zero mishaps. I think it fell right in the middle of 2 weeks where the higest temp was -5 and our lows were -15 average. The news crew interviews were all pretty much the same comments - "omg, how do you guys live in this? I would never ever leave the house!"
As for checker flag roofing, i could dig it. One could polish metal roofing, but it doesnt turn out that great on galvanized tin roofs. And around these parts, it would tarnish back to a cruddy hazy tin in 5 months. Chrome however...

*note to self* stay the hell outta Minnesota and Syracuse during winter.  After moving up from FL, I would never go back. There's like a masochistic romantic twist about owning a 4x4 pickup with aggressive tires and a nice warm wood stove in the cold crisp winter when the snow is coming down so heavy you can't see a foot ahead of you. It would be fun to buzz around on a 2T screaming sled, but that hasn't happened yet. |

Workshop roofing,I lived with my leaky tin shack corregated concrete asbestos type roof for a long time,I lifted if reset it still leaked, 2 years ago I got some 3X2 from packing crates and 8x4 marine ply from hoardings/billboards and re roofed the garage, covered it in shed grade roof felt.It,s bliss all for $80 plus blood sweat and beers.

I have a old truck camper that had a black rubber roof,it would get kinda warm inside.I replaced the rubber roof due to some leaks with white and could tell a difference.

About half of minnesotans own sleds, and you cant go 5 minutes in a snowstorm without hearing a pack of em screaming by. Its like heaven! |
