WINTER SHED & OUTBUILDINGS MAINTENANCE ADVICE DEFINITION OF ROOF LEAKAGE
**** A leak in any outbuilding roof, is when water
permeates through the external felt covering then through the roof sheeting from
the outside in and not any water, dampness or mildew on the internal roof
surfaces which can be caused by condensation due to natural atmospheric humidity
found in any unheated building in winter and extremely cold nights. ****
HOW CONDENSATION ACTUALLY DEVELOPS
Everyone should be aware, that internal roof surface condensation can occur in
"ANY UNHEATED"
garden outbuilding if it's left locked up and seldom opened during very cold
frosty days and nights.
In
winter months the outside roof surface of any unheated Shed, Garage or
Outbuilding will become frozen. (It will be primarily the most Northerly facing
surface, which is the coldest but it can sometimes be the entire roof).
Once the building starts to heat up during the day, the damp warm air will
rise and when it hits the cold roof it causes condensation to develop on the
internal roof surface.
This in turn will give you the impression that the roof is leaking (WHICH IT IS NOT).
If left unattended black marks will eventually form on the internal surface of
the roof, which is mildew, caused by the damp roof surface not getting dried
out.
During the winter "PLEASE"
open the doors of your outbuildings as much as possible to ventilate them, to
try and keep the internal temperature down (or fit ventilators).
We hope that the above information is helpful.
