This building was built in 1953. It is 2x4 walls on 24" centers with 3/4" tongue and groove sheathing on the inside and the outside with stucco on top. It has been neglected for quite a long time. The runoff from the roof was pooling next to the wall and running between the wall and foundation, into the shop. The gutter and corrugated drain setup is a stop gap to get through the winter.
The roof is 2x6 on 24" center supported by beams with 10' spans, with the same tongue and groove 3/4 for decking and roll on roofing over that. The roll on roofing VERY old and in desperate need of replacement.
This spring I will start with removing the roof, fixing any rot and then rolling on
Grace Ice and Water Shield HT. Then, steel roofing over that. The wall will get stripped on the outside of the building, all dry rot repaired, including a new pressure treated bottom plate, sheathed in whatever is appropriate (possibly) OSB and then steel siding. All new soffits will be constructed during the roof project with flashing, into the gutters. Yes, these gutters will have to come down. :/
The dirt adjacent to the wall... Well. I'm pretty sure I will dig over and construct a retaining wall to prevent the dirt from migrating back toward the building. Thinking of paying a contractor to do this part.
The downspout and the mini-split indoor and outdoor units condensate drains will also go into the corrugated drain pipe. I want to build a catch pan for the outdoor unit that will drain to the pipe.
This should have me weathered in and the dirt away from the building for the long haul.
I haven't seen that machine.. Model number??
