Does anyone know what the standard height measurement is between the last
shingle on a roof and how low or high the gutter should be? I had a builder
tell me that the gutters are too low after the second layer of roof shingles
were installed over the first. and that they needed raised up.

I'm not sure what the official spec for something like this is, or
even if there is one, but it seems to me that the thickness of another
row of shingles is not going to cause any problems.

Does the water go into the gutter. Yes - don't worry.

Place a straight-edge along the roof, extending over the top of the gutter.
If it touchs the gutter, and raises off the edge of the roof, then the
gutter is probably high enough. If the straight-edge lays flat on the roof
and passes over the top of the gutter, then water rolling off the roof is
likely to do the same - shoot right over the gutter.

It is my understanding that in areas subject to heavy snowfall, that the
front edge of the gutter should be in-line with the roof plane. This allows
snow that builds up on the roof to slide off onto the ground, instead of
piling up on the gutter and ripping it off the building.

We get our fair share of snow in the winter, so I used this method when I
installed my own gutters. It seems to work well, even in heavy rains. The
only exceptions are the areas where the roof valleys channel the water into
a single area. In a heavy rainstorm, these concentrated areas to tend to
flow out past the gutter. I can't really raise the gutters up much, so I'm
thinking it has more to do with the gutter screens blocking the flow more
than the height of the gutter.

"To ensure that gutters drain properly, make certain they slope (½ inch for every 10 feet) toward a downspout.
For gutter runs longer than 40 feet, it's best to pitch the gutter down from the middle to a downspout at each end."

I was not told this years ago when I got a second roof on top the old.

Twenty five years later, last year, I got a new roof and gutters.
Shingles do seem to lap further over the gutter as I discovered cleaning
them. If a new roof over this overlapped the gutters an extra inch it
would be tougher to clean them.

The original question was about the height of the gutters relative to
the roof, not about how far the shingles extend out. I agree with the
poster that said if a piece of wood laid on top of the roof just touches
to far edge of the gutter or is above it, then they are high enough.
The just touching concept is for areas where snow or ice slides off,
so that it will be less likely to hang up on the gutter. But the main
thing is if it's working, I wouldn't worry.
