Building a garage overhang (eyebrow)
|
|
| flyguy909 2006-07-23, 9:25 am |
| I'm residing a contempory house done originally in vertical cedar. The
gable ends, including the garage that bumps out, have no
overhang..looks like just a 1 x 8 board over the top of the siding
along the roof. Bogus design if you ask me.
I'm residing with better vertical vinyl over the wood, at least in the
front..standard horizontal the other 3 sides. Would much rather strip
first, but because of the design, would be an ordeal and expensive.
Before the siding goes on I want to build overhangs for the garage and
a door that are on gable ends and currently have no protection.
Exploring ways to do this...
- build mini half trusses that extend 12-15" over the garage and just
screw into the exterior wood every 24"
- tie them together with a facia board, then sheath with plywood.
Flash the top edge, add drip edge and shingle. Let the siders cover
over the top of the flashing, sides and underneath.
....same for the door but extend farther out.
I'm not a pro, just handy enough to get myself into trouble..seeking
advice..

| This approach would be very dependent on the strength of the
existing framing/siding. You lost me some with a 1/2 truss -
which half? You are talking about creating a barge rafter.
A very strong way to create the barge would be to remove and
replace the end truss/rafter/framing and use a drop chord truss or
rafter set with lookouts cantilevered over the drop chord and well
fastened in the common rafter.
A less strong method would be to strip back the roof sheathing and
replace it with an overhanging amount. On new work it would be
usual to extend the ridge board to carry the tops of the barges
and to extend the sub fascia to carry the bottoms. The roof
sheathing actually carries much of the weight of the barge. Add
lookouts and soffit to stiffen the assembly. This method can
droop over time, but is not unusual. The roof sheathing carrying
the barge functions a bit like cantilever with more material back
into the roof than out over the eave.
I just re-read your post. Are you thinking of your 1/2 trusses
coming out from the building to look a bit like a Mansard? In
other words are you thinking a parapet condition along the
existing gable face? It might actually work and look interesting.
It would sure be nice to CAD or sketch the concept well to see
"the look".

| The garage is attached to the house and the garage doors are at the
other gable end. This gable wall, like all the other gable walls on
the house have virtually no overhang... just 1 by 8's over the siding
along the slopes. What I want to do is build a little sloped overhang
just over the top of the garage doors like this.. (side view, hope the
spacing holds) the lines at the top are the main roof shingles.
