I plan to have additional ridge vent installed. The roof has about 10-15’ of ridge that doesn’t have any vent. Additionally, part of the existing ridge vent has only one side of ply board cut (bad builder!) After inspecting the soffit vent around the house, I think it has enough continuous vent. The temperature in the attic in the summer is exceedingly hot (around 130 - 145 F).
Will adding additional ridge vent help? What is the approximate cost? I live in the Houston/Sugar Land area.
I also need a contractor interested in this seemingly small job
Thank you very much in advance for your advise.
