Installing Gable Vent - Wood Cedar Shake Siding

Hi all,

I'm refinishing my garage and would like to install a Gable Vent to vent the small area between the cross joists and roof before I sheetrock. Should I take off the shakes outside one by one, install the vent then reinstall the shakes? Or, should I lay out my template on the inside sheathing, drill holes in each corner, run a chalk line corner to corner then use a circular saw to cut-out the hole from the outside?

It depends how careful you measure and cut. If I were doing it I would remove plenty of shakes, cut the opening and install the vent. Then when reinstalling the shakes you can do a nice job on reinstalling them. No chance for a messed up cut and having to buy new shakes that won't match to repair the damage.

The easiest way is probably just cut out the opening and shove in the vent.

However, I would carefully remove the shakes and then cut the opening. That will allow you to weather flash the area around the opening. I would also frame the opening on the inside to provide a solid nailing surface for attaching the vent. It also provides a flat surface for the vent flange to sit on.

After the vent is in place you can caulk around the vent and replace the shakes.
