How deep do I go? Replacing dormer siding on 1915 house.
Hello- I’ve been digging into this fantastic treasure trove of articles for a couple of days (and nights) as I plan a re-side project on my dormers (In St. Paul, MN).
The problem is that as I read more, I’m starting to add so much to the “might-as-well” list that it will easily spiral out of control in terms of time and budget.
So- where can I draw the line? What techniques should I use depending on where I draw the line? Here’s what I mean:
Siding: I want to add new shakes of engineered wood (LP SmartSide) or fiber cement. Currently has cedar that’s old, warping, poorly maintained trim, etc.
Rainscreen: I am convinced of the need to use a rainscreen.
WRB: I know I need a WRB (there’s probably real felt under there now).
Sheathing: As far as I’ve seen I have original shiplap for the sheathing. I don’t really want to update the sheathing.
Exterior foam boards?: having read the article about dew points and exterior insulation (How risky is cold OSB?), I’m not sure I can realistically handle the fattening of the dormers by the several layers of foam board (how to do tie-ins at roof lines and along lower level vertical walls- I’m not re-siding the whole house!).
So I am thinking that if I don’t do the exterior foam boards, I’ll demo down to the sheathing, wrap with tyvek or other WRB, and use Cor-A-Vent sturdie-strips behind the siding.
Am I crazy to be doing a partial re-side in MN and NOT add external insulation?
