I am about to put a ridge vent in my home, pitch is 12 - 12. I will be cutting the vent in and putting the vent in myself. I will have help on the ground, but only me on the roof. I see two types of vents, the roll out ones and the sectional, I think 4 foot long pieces. Which do you think would be easier to do without any rooftop help? Leaning towards the pieces instead of having the roll keep falling as I roll it out.
