I want to add insulation to an old ranch house. However, the insulation contractor wants to add static vents (2 turtles and 2 pipes). He says I don't have enough ventilation in my attic.
The roof already has a ridge vent. It also has a gable vents but no soffit . The attic seems fine to me. The attic temperature is always within +/- 10 of the outside temperature.
The house is in MA; so we have extreme weather. Even in the coldest winter, there has never been ice damns. There is no known mold issue. The shingles have aged well, the roof is almost 25 years old. I think it's time to start thinking about a new roof.
Should I think about changing the roof or keep it as is? I'm a big believer in "If it's not broken." Was the insulation guy misinformed?

I would not anything more to the roof. You probably have enough flow through the ridge and gable vents.
If you're really concerned, soffit vents should be next. But a lot of them I've seen do not have enough free space area, or net free area to be effective.
