Can wood lap siding be done well without caulk?
I am residing a house with beveled cedar lap siding. I would like to avoid using caulk but don’t know if that is prudent where the siding butts against window and corner casings; this being a vertical joint I’m not sure if flashing would be effective. If I flashed with role flashing centered behind this joint between the siding and vertical casings would that suffice? Would metal flashing here be overkill and an extra layer of felt suffice?
On the north face of the house there was some water damage the sheathing at these vertical joints where the original wood lap siding butted up to the vertical casings. The north face has a gable so the 9” overhang doesn’t do much to keep water off the siding. On the siding that I am taking off caulking had been done at some point in time but its hard to determine if the caulk as it degraded helped or exacerbated the problem by trapping water. The house was built in 1907 and has 1x sheathing and rosin paper over the sheathing. I will be removing the siding, adding felt paper and furring out for a drainspace before residing with the new wood siding. I just had the house insulated with dense pac cellulose (the house is in Minnesota.)
If you think I should use caulk at the vertical joints please describe what constitutes a high quality durable caulk. I’m a bit overwhelmed by the selection of caulks available.
