After the high winds we recently had your aerial might be a bit...tired or indeed fast asleep
if not dead. If your aerial is sprawled out on the roof and had enough it is time to call
us to take it down before it causes damge or hurts someone.
Now if you aerial is a bit on a wonk still holding on for dear live to that chimney you want to consider getting it fixed or taken down as it can
a) cause damage to your chimney by grinding into it through
swaying and vibrating in the weather
b) cause damage to the roof when it finally decides to give up, especially older models
can be quite hefty
c) create a bit of noise and keep you up at night, the chimney almost works as a funnel
and amplifier
