Several customers old and new have been having trouble with bird damage this winter. It can happen a lot at this time of year as the hollow stems and gaps between them provide shelter for hibernating flies. Jackdaws in particular will work their way up the hips and barges pulling out a straw at a time, teasing out flies too sleepy to flee. It doesn’t take long before the lawn below looks like half the roof has fallen on it. It’s rarely as bad as the evidence would suggest, and depending on the age and condition of the roof, there are several things that can be done, from repairing any holes, to wiring the weakest points to discourage the birds.
Below are pictures showing a patch beneath a chimney before, during and after. We wired this barge some time ago, so it just needed tightening up all over once we had finished.
