I have a non-functional roof fan. I want to remove it and replace it with
a vent (as recommended by my home inspector).
To remove the existing fan, it appears that I need to lift shingles.
1) is this a DIY?
2) if so and is pretty easy, any advice on how to proceed?

Quite easy, providing the pitch of the roof allows you comfort. Anything 6 in
12 or over should be secured for safety. Cut the power to the unit. Using a
flatbar, start by removing fasteners 2-3 rows above the vent, and about a foot
beyond the sides. Working your way down, you can cut the shingles away, always
cutting above the slot in the shingle. If they're dimensionals, keep your cuts
at least 4 inches away from adjacent(above or below) cuts and butts. When
you've removed the shingles covering the flange, remove any fasteners holding
the flange in place, and carefully remove the unit. Rewire the new one, install
it over the hole, and use new shingles to repair the roof. Everywhere there was
a fastener is a possible leak point! If the new shingles look out of place,
it's possible to re-use the old ones, or pirate some from another, less visible
roof area. Instructions are on the back of every bundle. Good luck! Tom

Why replace it? If you are thinking about replacing a non-working
electric vent with a slant-back vent, there won't be any change in
your attic ventilation. Right now you have a hole in the roof for the
electric vent that will probably be the same hole for the static
vent--what's the difference?
I'm no expert in ventilation for colder climates but I would think
that an electric vent with a humidistat whould be a good idea. I
believe one of the major concerns in colder weather is to make sure
the warm humid air is expelled from the attic before it can condense
on the cooler decking. A static vent will help do this, but an
electic vent with a humidistat would move more air when the humidity
level reaches a pre-determined humidity level. (But I don't know if
there are other concerns).
Generally speaking, you can't have too many soffit vents.
This is Turtle.
if you live in the Southern states you really need to put the Electric fan type
vent fan back on it. If you live in the northern states you can go back with the
static air roof vents. The removial of the fan is nothing to do if you just do
as Tom said.
Electric fans cost about $29.00 to $69.00 depending on the quality.
The static fans cost about $18.00 to $28.00 depending on the Quality.
If you live in the southern states the static fan type will cost you big time
over the life of your ownership verses the electric type. It's your money and
