I have begun to turn my shed into a work space for me and over the past few nights the temps have started to hit the 50s. So I threw a space heater in there too keep the temps up.

Over the past 2 days I noticed that the singles on the outside of the roof looked wet. This morning they looked even wetter.

I have been thinking about insulating the shed. I didnt think I would have too because the space heater was keeping it at a great temperature.

But should I add roof insulation to stop this condensation problem?

Any advice?

It has nothing to do with insulation. What you see is dew, and unless you keep the shed heated 24/7, you'll get that no matter what you do, and you still might get it if it's heated.

Thanks Richard.

Maybe I wont have to insulate the shed afterall then. btw... I am near toby... Up by milford.

Do you think the space heater will be sufficent this winter to keep temps around the upper 60s in the size shed I have? Any other measures I should take?

To answer that question, the capacity in BTUs of the space heater would have to be known. It produces so many BTUs per hour (sometimes abbreviated BTUH). The structure will allow so many BTUs per hour to escape. If the BTU rating of the heater is greater than the heat loss of the structure, then, yes it will, but an awful lot of heat will be wasted also.

Let's say you insulate the walls with R-11 fiberglass. Divide ONE by that 11, and you get .091...that is the U-factor of the insulation, and it means that .091, or about a tenth of a BTU will be lost through the insulation for every square foot of it. That's how you can calculate the heat loss. You can look up U-factors for various materials on the internet, I'm sure. We architects have expensive reference books that give us such information.

My guess is, especially if you're in Pike County and the heater is electric, you'll want to insulate the shed.
