Hi, Mac. Where I live, we have a story about a little boy who put his finger in a dijk, and in doing so he saved the town from a flood."Nice".but not true. If you put your finger in the hole the water will still keep coming..IN OTHER WORDS THE PROBLEM GETS LARGER. and so will the rot you have in your facia,replace the rotted timber paint it and then if you wish cover it with alumininum.
