I saw my father install a turbine fan a while back and would like some
help and info on adding one to my mom's garage.

I thought the thermostatically controlled fan would be best.

Is there a template in the box for the hole size?
I know I will have to remove some shingles, can they be re-used as I
have no orig. replacements?

Garage size is 26 X 30 ft.

Thanks.

Proably, but t hings like that can vary between brands.

Depends. If fairly new, no problem. If older, they will break when you take
them off. Thee is always risk in projects with re-use.

Broan has a selection of roof and gable fans that come with templates.
Here's an installation manual off their website for one of their roof
fans:

You do not need to reuse any shingles, but you do have to cut some out
and loosen some up and remove some nails in order to slide the fan
flashing underneath. This is done by lifting the edge of the roof
( which if the roof is old you might break the shingle) so you can
expose the nail, then you remove the nail with a small crowbar or
similiar tool.

Before going ahead with your project, have you talked to several people
in your area who have added such fans and asked them what they think?

I have heard a lot of complaints about them. Too many are cheaply made
and fail in a short time. Often after they fail the owner does not want to
bother replacing them because they failed to make a noticeable difference.

While I am sure that they may well be useful in some areas, especially
in a garage application, my personal experience in central Ohio has
convinced me not to bother. I had thermostatically controlled powered gable
end fan. Everything worked, but I doubt if it reduced the heat more than a
degree or two. Not enough to notice. I would not mind having a ridge vent
along with lower intake vents in a garage, but certainly a powered vent was
just not worth it for my situation and maybe yours.

As said, if are old and dried out they will most likely break.

- Should you go ahead with this, do it when the sun has been hitting the
shingles for some time so they are soft.

- losen the sealing tab by wedging a putty knife in.

- removing a shingle requires you to remove the nails from the row above
that and the 2nd row above it. The upper edge for the one you are trying
to remove is caught by that 2nd row above. You don't actually have to
remove the shingles above, just get the nails out.

- For removing the nails many people use various flat bars. But the thing
I have found works best for me with the least chance of shingle damage
is....a short handle shingle rake. Nice and flat. Many teeth. Prys at
teeth by pushing down at entry point so you are not bending the heck out
of the shingle you are trying to remove.

Renailing without a roofing nailer can be tricky. Shingles can get
damaged.

- Put roofing cement over all old holes and new ones since you're at it.
Also put roofing cement where the old sealing tabs are/were.
