The house it not insulated properly nor vented properly and neither of those issues will see a fix for quite some time. Too many things ahead of it.

Melting snow/ice not collecting in a cold gutter and freezing will certainly not make matters worse.

I've removed the gutters from 3 of 4 of the last buildings I have owned and it was a much better situation after they were gone. This building is typical of those three.

I WILL NOT BE INSTALLING GUTTERS ON THIS HOUSE.

I will put a drip edge on the roof above the rear door to redirect the rain at that single point no no others...

Did I say "no gutters"?

If ya missed it

NO GUTTERS!!!!!
