Think of your roof as an extension of the ground. Keep your antenna about
1/2 wavelength above the roof to keep ground losses and elevated pattern to
a minimum.

Subject: [TowerTalk] How Far from the house not to effect antenna pattern?
Hi Guys,
One question I have always had about towers that are placed near the house
is how much does the house wiring and gutters effect the antenna radiation
pattern?
And if the house has a metal roof ... what effect does the metal roof have
on the radiation pattern? I ask because I've been considering a metal
roof.
One thing I have experienced first hand with towers near a house is
increased QRN. Guess that's a no brainer but it's a factor worth
considering if one has the option to locate the tower a good distance away
from the house.

I also know, that there are millions (literally) of towers put within 4-5
feet, if not closer, to homes, with no coupling issues.
I wouldn't go so far as to say that.
The accurate way to say that would be....
I also know, that there are millions (literally) of towers put within 4-5
feet, if not closer, to homes, THAT HAVE NEVER SUFFERED SEVERE DAMAGE
...BUT OF COURSE THEY MAY NEVER HAVE BEEN HIT EITHER.
It makes perfect sense that planting a tower next to the house is
significantly worse than having it some distance away. Even a small
distance of a few feet is better than bolted directly to the house.
I think the suggestion of some spacing is a good one, even if the "required
distance" is a number pulled out of an area near someone's back pocket.
