Other than being old and rusty they are working fine based on my obser.
Mroof drips between the gutters and fascia.
Assuming the gutters have the correct slope the main reason for overflows is that the gutters are full of debris and need to be cleaned.
Any rainwater or in sparodic areas then simply misses the gutter.
A new roof is a huge project and one that has to be carefully balanced with the rest of the fixtures in and around your home.
Why is a drip edge important.
The correct placement of a roof drip edge is on top of the roof s exterior cover directly between the sheathing and the fascia board which forms a drainage gap between the drip edge and the fascia board.
If the problem started popping up just after or recently after a roof installation there are good odds on the contractor not taking the gutters into account during the service and construction.
Incorrectly sized poorly adjusted or shoddily fastened gutters can lead to excess space between the gutter and roof which will lead to water falling in between.
This then pushes the guttering out from the roof line by 9 17mm.
The gutters are getting old and i want to replace all.
The gutters then direct the water to a downspout allowing the water to run down until it reaches the ground.
But what happens when your roof s gutters become worn out or cracked or clogged.
Water leaking between gutter and fascia when there is rain the water is expected to roll down the roof and into the gutters.
Without looking at the roof it seems that the water is missing the guttering because perhaps the previous owners may have had new fascias overlaid onto the old.
