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
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.
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.
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!
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.
The rolling barn door track required trim to
not only cover the galvanized hardware and make it look better, but also
to further weatherproof the area above the doors. Earlier, I
had mocked up a sample piece of trim from some scrap lumber, and had
made design modifications as needed.
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.
