Sheathing

The roof sheathing is Avantech tongue and groove OSB, an engineered product intended for this use. Amazingly, Bob sheathed most of the roof alone, heaving the sheets of sheathing up on a ladder.  Not fun, in my book.  With the roof sheathing done, there was at least some semblance of protection to the room below.

Soffits and Trim

Before any shingling could occur, the roof trim (soffits and facia) needed to be constructed.  The trim details on the barn are pretty basic and typical:  12" overhangs on all four sides, including the gables.  The trim consists of a vertical facia board secured to the truss ends with a smaller trim board at the top edge; the top edge is beveled to match the 8:12 roof pitch.  The soffits are 1/4" AC plywood on the gables and 3/4" pine on the sidewalls.  

On the side wall overhangs, a full-length soffit vent is installed which, coupled with the full-length ridge vent on the roof, provides the ventilation required for long roof life.  The trim work took two days in total to create, although the work was staggered by a week or two, with one gable and one sidewall completed and the roofing begun on that side before any work moved to the other two walls.  This was done in order to minimize repositioning the pump-jack staging from side to side (a big job in and of itself).  Standard drip edge was installed on all edges of the roof.

Trim details on the building include standard cornerboards  and flat pine trim around the door openings.

The roof shingles are 30-year so-called "architectural" shingles--you know the ones.  They're the layered, textured shingles that you see on virtually every roof these days--much more interesting to look at than the old flat shingles.  I chose basic black for the barn roof.

What more can I say?  Here is the finished roof.  There's a full-length ridge vent and white aluminum drip edge on all sides.  It looks good, and sure was nice to have in place when we received heavy rain only a few hours after Bob completed the ridge!

Other Trim

The door openings and building corners are trimmed with flat pine stock, as is common.  I further trimmed out the multiple windows with flat pine stock to match the other trim on the building.  The flat trim finished off the windows nicely and helped enhance the overall "barn" look I was hoping for.

Armed with the appropriate pieces of 3/4" thick pine, I constructed the door track trim in the shop, and raised it into place in two sections (on the wide front doors) and all at once (on the side door).  The trim for both sets of doors is basically the same, although the sizing is a bit different because of the single vs. double tracks on the side and front doors.  Each section consists of three pieces:  a vertical top strip, 3-1/2" wide, to which is fastened a sloping "roof", with 45-degree bevels on each side, which covers the top of the track, and a final vertical trim piece beneath, covering the front side of the tracks.  The trim basically forms a simple shed roof over the tracks.  I screwed and nailed the pieces together, and caulked the joints to make it watertight.  Then, I screwed the pieces to the walls as required, and caulked the final seam between the siding and the trim.
