The problem is when it rains the sound transmits through the ducting down to the range hood.
Roof vent rain noise.
The rain water then trickles through the lattice then drips on to the original roof surface and away in to the rain water drainage system.
Rain noise from roof vent cap.
Lift up the edges of the surrounding roof shingles so you can see the edges of the vent.
Often a stiff wind will open vent dampers causing them to periodically clang shut.
Remove the screws holding the vent in place.
Roof noises may be described as those attributed to an obvious source.
We recently installed an island range hood with rigid ducting venting through roof.
If the noise drives you crazy new spring loaded backdraft dampers 9 to 30 depending on the size should solve the problem.
This is very loud and sounds like rain on a tin roof right above my head.
Climb onto the roof and locate the vent that is causing the noise.
The material is black in colour and is uv stabilised.
The vent hood ducts through a rigid or flexible pipe to a cap on the roof or side of your home.
