I have to replace the shingles on my 20 year old house. The interior weather liner in the rigid plastic ridge vents has deteriorated. Is there a replacement material available?
New ridge vent should be used
You could use cedar breather, but the labor cost to try and remove plastic ridge vent and reinstall it far exceeds the cost of purchasing new.
And the cost of the cedar breather would equal or exceed the cost of new ridgevent.
