We are in the process of having our house re-roofed and seamless
gutters installed. Although the roof installation looks good, the
gutters were horribly installed. They will be removing them and
reinstalling. However, we are being told some things by the
contractor which we question. I'm hoping someone can comment on these
My understanding is that seamless gutters are in fact seamless except
for the corners. NO seams within a straight stretch. The contractor
is stating that because the roof line and/or rafters are not perfectly
straight, that they must put seams in within the length in order to
compensate for the change in angle. The amount of discrepancy in my
opinion is negligible, and I would think, the norm for any roof. If
that's true, I'm sure that there is a way to deal with minor
discrepancies without having to make a seam. Which of course defeats
the purpose of seamless gutters. The downspouts should also be
seamless except at joints in order to hug the side of the house/deck,
Any seams (corner or otherwise) should be caulked and riveted. Should
caulking be applied in the inside lip only, or also on the outside?
Should it be a big glob of caulk or fairly neatly applied?
Is it true that there are only a very limited colors available if you
want to have the color manufactured into the metal? And if you want
another color it would have to be painted after the length is
Is there some sort of authority on seamless gutters that we could
reference if we continue to have a dispute on any issue?
Thanks very much for your help on this!
If the fascia board runs straight across the rafters without jogs for
different planes in height for roof. Your contractor is outright lying to
Downspouts are _not_ seamless. To my knowledge no machine exists to make
seamless downspouts (aluminum). They are usually sold in 10' lengths for
residential use. The back of the downspout has a seam also.
Painted aluminum zip screws are preferred over rivets. Caulking on inside
only, neatly applied.
You are limited to colors. All colors are painted on either at the
extrusion plant (baked on) or field applied. They can not manufacture color
throughout with aluminum. This is providing you're not speaking of
<shudder> vinyl gutters.> Is there some sort of authority on seamless gutters that we could
At this point, I would be more concerned of the job they did on the roof.
The roof might look good to you, an expert opinion may say different.
Getting an expert opinion on someone elses work, you will probably have to
Seamless gutters are just that- seamless gutters. The gutter being the
trough that runs horizontally to catch the water. These troughs have to be
connected to corners, or downspout ends, either of which is a seam. Ours
are sealed with some type of goo, from the inside. Ours was very neatly
applied. Not sure what type of mechanical fastener was used to connect the
gutter to the corners.
Downspouts are also not seamless, at least not the ones I've seen.
We had a fairly limited color selection if I recall, but our gutters are
white to match the facia color, and the downspouts are grey to match the
siding. I guess we got lucky there.
I suspect you will need to choose an existing color offered by your
installer, and try and paint it yourself after the install is done.
You could always ask about having the parts painted first, but I wouldn't be
suprised if they installers are resistant to the idea.
In any event, I'm sure having that done would be pretty expensive. Never
hurts to ask, though.
Despite an earlier post, you do not have to have the gutter forming machine
on site. Ours was not. The crew took all the measurements prior to the
install, the delivered the guttes already formed and at the correct length.
And this was from a very competent and skilled installer.
Galvanized steel? In our area, they're gone many years. Even HD does not
sells it now. That will need painting then. My old house built in 1976
had galvanized steel gutters with all the seams soldered and painted.
That was the last of it.
