I bought a house with a satellite dish on the roof. When I remove it, how
do I patch up any holes that will be left behind? There must be a million
sites that tell you how to install one... but I can't find one to tell me
how to remove one! ;-)
Remove the screws - get a tube of clear silicone caulking and fill the
holes. If it is dirty around the holes - make a solution of 10% bleach
and 90% water - brush the area lightly and lightly hose it off. You will
not see the repair.
As a person who does 150-200 roof repairs per year, I will
have to disagree most heartily with this advice. Many of the
repairs that I do on asphalt shingle roofs have already been
repaired with silicone. I then have to remove the silicone
and clean the area, then install a caulk that is compatible
with asphalt. A couple of these are Geocell 2300 Tripolymer
sealant and PL2000 urethane sealant, found at roofing supply
stores (Not HD or Lowes).
I have told my crew that I will fire anyone that I find on a
roof with a tube of silicone, because of the liability that
the use of this stuff places on my company.
Silicone has many uses, but none of them are on a roof.
If you have a metal roof, NP-1 is the way to go.
Concrete or clay tile, NP-1 or Geocell.
NOTE: Flexseal is forsale in many places, and claims to be
compatible with asphalt, but in my experience it is not. My
roofing supply now refuses to carry it due to this problem.
