I'm still not sure I understand, but see if this makes sense. When you
cut the triangles, cut them larger than the pattern says you need them.
In other words, if the pattern tells you to cut 2 5 inch squares and
slice them on the diagonal to make half square triangles, go ahead and
cut the squares to 6 inches. Attach them. Then trim to the correct size.
There are so many house blocks, I can't visualize the one you're
describing. If your block has a name, tell us, and we'll google to find
it online. If your block is in a book, tell us which one. One of us
will have it and will be able to see what you're describing. If your
block is from a pattern, tell us which one. We'll google, find it, and
be able to answer your question better.

But how do I get the correct size without cutting off the point of the roof?

The roof is shaped like this --> ^ It's like an upsidedown V. The roof
must come to a point and have 1/4" seam allowance. Same for the sides of the
roof. They don't reach the walls of the house.

^
The house is 2X4" with an unsidedown V shaped triangle for the upper part.

It's just called a house block.

You may need to draw this on paper for it to make sense.
You DO cut off the top point, BUT a new point is created when the other
pieces are sewn on.
The point that you will see in the finished product will be created when
all 3 seam allowances are figured in.
Try it on paper. Draw your triangles the way they fit together without
seam allowances. Now take a different colored pencil and draw a line
that represents seam allowances. See the way a new point is made?

For some reason the top of the point is at the top of the square so when the
next block is added the point is gone into the 1/4" seam. The sides are the
worst. The points of the edge of the roof are squared off in the seam. I
can't get a good seam allowance and I can't remember how it's done from
years ago. Basically I'm sewing 3 triangles together to make a finished 2"
by 1" rectangle. The rectangle has to be 2 1/4" by 1 1/4".

But there is none at the bottom of the rectangle made of the 3 triangles.
The point comes right to the edge and is squared off in the seam. The top
barely has a seam allowance.

I see a confusing tangle of different colored lines. When the material is
cut out and sewn together I either have no seam allowance at the top or none
at the sides and lose the points at the sides. I have searched everywhere
for my old book with the instructions to make these. I have 5 quilting
books and not one explains how to sew 3 triangles together to make a
rectangle. I'm truly at the point of frustration after hours and hours at
this one piece.

The bottom line is:
Either the pieces are cut to the wrong size,
or the quarter inch seam allowance is wrong,
or they don't fit together on paper.
That's it. It can't be anything else.
The only other thing I can suggest is to draw, in pencil, the exact size
of your pieces. Cut out the pieces with scissors. Don't worry about an
exact quarter inch. Now sew, by hand, on the pencil lines. In other
words, do what I was suggesting with paper, but do it with fabric.
