If you have water getting behind the gutter in any way that will start to soften and eventually rot the wood.
Gutter spikes not holding in facia.
Once this happens the wood will no longer be able to support the gutter and the gutter will either start to pull loose or sag in that area.
If the head of the new gutter spike can fit through the front hole on your gutter drill a new hole 1 4 inch 0 64 cm away from the first one that s the same diameter as the spike s shaft.
Just hook the bracket under the front lip of the gutter and then screw the other side of the bracket to the fascia.
Replacing them with steel gutter screws and rigid plastic ferrules provides a more secure alternative and will prevent them from pulling loose or sagging.
To replace gutter spikes with screws simply remove the old gutter spike and insert the screw through the existing hole in the front of the gutter.
Then use a cordless drill to drive the screw into a new hole in the fascia board.
One way to make sure your gutter doesn t fall off the house is to install fascia hanger brackets.
