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.
No gutter spikes on my gutters.
Pounding them back in is a temporary fix at best.
First of all the first thing you need to do is to remove all the outdated and defective gutter ferrules or spikes.
Years ago spikes and ferrules were a common method for hanging gutters.
Replacing them with steel gutter screws and rigid plastic ferrules provides a more secure alternative and will prevent them from pulling loose or sagging.
They are also the easiest thing to fix.
Whenever you can see your gutter spikes hanging out of their holes that means you have loose gutter spikes.
Just because your gutters have loose gutter spikes does not mean you need to replace your gutters.
They do the job all right but eventually the spikes work themselves loose.
If they really won t hold maybe you could squirt some silicone or construction adhesive back into the hole before putting the spike into the fascia as a temporary fix to keep them from working out again when the old gutters are taken down you will probably be able to see where the fascia has been nailed to the rafter tails.
One way to make sure your gutter doesn t fall off the house is to install fascia hanger brackets.
Then use a cordless drill to drive the screw into a new hole in the fascia board.
