Figuring out which ridge vents work best with GAF shingles
Just finished installing some GAF shingles on my roof, and now I'm looking at ridge vents. Here's what I did: checked GAF's site, matched vent specs to shingle type, and made sure airflow ratings lined up. Seems straightforward, but maybe I'm missing something...anyone got better tips or tricks?

"checked GAF's site, matched vent specs to shingle type, and made sure airflow ratings lined up."
Sounds like you're already on the right track. Honestly, people tend to overcomplicate ridge vents. I remember a job a few years back where the homeowner insisted on some fancy vent system that promised miracles... ended up performing exactly the same as the standard GAF-recommended vents. If you've matched specs and airflow, you're golden. Trust your prep work - you're probably more thorough than most pros I've seen out there.
One thing beyond matching the vent specs: have you checked that the soffit intake is continuous and unobstructed? A ridge vent can be rated for plenty of airflow, but blocked insulation or limited soffit openings can leave the system unbalanced and reduce its effectiveness.
