I have an overhead garage door that is apparently made of a composite
skin over composite bracing. Although painted, it appears to soak up
rainwater and rot. I tried patching it with bondo, but that didn't
work. So now I'm looking for a replacement that is impervious to water.

The dealers around here have wood doors, and steel doors. They claim
the finish will protect them, but I'm not confident since wood rots and
steel corrodes.

Are there better options. I would think fiberglass or aluminum would be
better.

My steel door is by Overhead Door. After 12 years, it is still in
perfect condition. Yes, aluminum may be better (and more expensive),
but this is working for me.

They have fiberglass also.

Nothing wrong with either. Wood will require a bit more maintenance.

Fiberglass overhead doors suck. They're translucent and very light
(easy to damage). Aluminum will cost an arm and a leg and probably
still not be strong enough. If I were buying a new door it would be
steel (probably with insulation and interior panels to quiet it some).

Wood rots and steel rusts if water is allowed to get to it.
I have 30 year old garage doors and no rot here. You do
have to keep them painted and make sure water isn't
getting to them in ways in should not. Haven't done anything
special here and they are still in great shape.

There are two Raynor fiberglass OH doors here that are at least 40 yr of
age and are still just fine. They aren't particularly attractive,
granted, but it's a standalone garage on a farmstead so that doesn't
bother me much (as in any). And, the translucence is kinda a nice thing
from a light standpoint if there isn't sufficient other light.

OTOH, there are also fiberglass OH doors of the ilk of residential
exterior doors that are can be quite attractive and not at all
insubstantial (of course, the price isn't, either, but none of anything
that aren't just cheap are).

I have no idea how old my wooden garage door is but it's been here as long
as I have, going on 30 years. No rot whatsoever. I wouldn't be surprised if
it was original to the 55 YO house.

On the other hand, one of the rails that (used to) go down into the
concrete rusted out and there's a gap of about an inch between the slab and
the bottom of the rail. It's not a problem because it's secured to the
block just above the gap and since the bottom is no longer in contact with
anything, it stopped "receding" years ago. :-)

I would NEVER recommend a fiberglass window, fiberglass door or fiberglass anything including a fiberglass garage door. The problem is that fiberglass isn't "tough" the way wood or PVC are in that the threads of a steel screw will cut a new path into it. With fiberglass, every time you take a screw out and put a new one in, that new screw's threads cut a new path through the fiberglass, breaking the glass fibers and causing the hole to enlarge. The result is that fiberglass doors and windows are a nightmare to maintain because the screw holes in them always get larger, and I don't expect a fiberglass garage door would be appreciably different.

Your best bet is still steel in my humble opinion. Millions of people have steel garage doors and they provide good service all across the continent. They're lighter than wood doors and generally never require any painting. While it's true that steel rusts, it's also true that the outside of the door is protected by paint and it seldom rains inside the garage. Bottom line is that your experience with a steel door probably won't be any different than anyone else's, and most people are happy with their steel garage doors. I know that both of my sisters are.

I replaced my 40+ y/o double wooden door last year.

The main problem was a gap on one side and they looked old.
There was no wood rot. I don't think the door warped to cause the gap.
It might have been 40 years of settling.

I mainly replaced them to upgrade the appearance.

My previous house, I had some +50 year old wood doors in perfect
condition.

I conclude that real wood will last a _really_ long time.

I had Jaeger Lumber install some steel clad doors.
They look great and don't make a huge noise when being opened.
Good enough for me.

close second. The only real problem with wood is its weight.

How about a garage door "engineered with an artfully molded wood-grain
fiberglass surface concealing durable steel construction",
Polyurethane foamed-in-place-insulation, and "optional insulated glass
for improved thermal performance"?

No translucency issues because of the steel core, some light because
of the windows, energy efficient and "the warmth and beauty of wood
with less maintenance".

What more could you ask for? ;-)

My mother's started breaking in the first few years. I was constantly
trying to put it back together. They're so light and flexible that
the banding at the top and bottom would snap, making it work more like

"Made like" is often used as "constructed like". Sometimes you have

My attached garage has wooden doors that have lasted since 1984. I guess
the fact that I have an overhang over the doors has contributed to their
life.
Wooden doors insulate better than metal doors. Nothing ever freezes
inside the garage even when temps outside drop to single digits. If I
were to replace them for whatever reason they would be with wood again.
YMMV.

work. So now I'm looking for a replacement that is impervious to water.

The dealers around here have wood doors, and steel doors. They claim
the finish will protect them, but I'm not confident since wood rots and
steel corrodes.

Are there better options. I would think fiberglass or aluminum would be
better.

My attached garage has wooden doors that have lasted since 1984. I guess
the fact that I have an overhang over the doors has contributed to their
life.

Perhaps, though the degradation I've always noticed was on the bottom,
where they may have not been allowed to dry properly after rain.

Wooden doors insulate better than metal doors. Nothing ever freezes
inside the garage even when temps outside drop to single digits. If I
were to replace them for whatever reason they would be with wood again.
YMMV.

Wood? Insulate? Hardly. The R-value is about nil. A foam insulated
steel door would be *far* better. OTOH, I'm not convinced it matters
all that much because I don't believe a decent seal can be made and
maintained all around a door that size.
