My roof guy said ridge vents shouldn t be installed at different heights.
Getting a liitle rain through my roof vents.
As it spins the air blown from the vent is strong enough to blow rain away from the openings between the fins.
It this is the case you need to create a breathable shield to slow the driving rain drops while still allowing air flow.
For example along the long peak and then on the gables that blend into the roof at a lower level than the highest long peak.
The rigid plastic vents generally work well so the problem may be.
If the edge of the hole in the roof deck is flush with the inside edge of the vent it may be possible to install metal straps that are screwed into the walls of the vent and attached with short screws to the bot tom surface of the roof sheathing.
The reason being is the the higher long peak ridge vent end up drawing air through the lower smaller ridge vents on the peak.
Okay to get that long standing warranty that jim from ideal roofing can give you being a master elite roofing contractor.
However when there is rain and no wind water can enter the attic and land on the insulation since the blades are not moving.
The ridge vents are designed to cover the gap at the top of the roof much like the hat you wear in the rain it is designed to keep rain and snow out under normal conditions.
That s right snow in your attic.
Deflectors are available in many sizes configurations and colors to match your existing vent cover.
My home has three whirlybird turbine vents on the roof.
And open sunday plenty of free parking.
And on occasion a hard driving rain with whipping wind will cause roof vents to leak water.
Unfortunately if things aren t quite right with the vent and the weather conditions are right you can end up with attic snow.
They have to have the gaf master elite roofing ridge vent on there with the roof and that would not blow water.
Normally when there is wind and rain no water will enter the attic space due to the blades moving around.
If your roof vent leaks during heavy rain the rain may be blowing up under the hood and into the vent.
A improper installation or b some roof feature which is directing the wind and rain into that part of the vent.
