Here's the evident damage from the woodpeckers.
To prevent the woodpeckers from damaging the home I installed several "Intimidator" bird flashers.
The Intimidators reflect the sunlight and spin in the wind, which intimidates the bird to thinking there is a predator near by. This is a visual deterrent and is an extremely effective and humane solution for keeping pest nuisance off your property.
Next, I patched the holes using a wood filler.
I made sure to fill in every hole.
Lastly, using the paint the homeowner provided me, I painted the cedar shakes so that it looks exactly like it did before the damage.
