Builder's Best 084633 Galvanized Steel Roof Vent Cap with Damper & Removable Screen, Black (Discontinued), 6" Diameter Collar

I bought this Galvanized Steel Roof Vent Cap to vent a dryer, which was a mistake as the vent cap incorporates a collar. A vent cap with a collar works well on a new roof, before the shingles are installed. On an already shingled roof, the collar doesn't allow for the vent cap to slide under the shingles. In my case, it was a little too late to purchase another vent cap, so I simply cut the collar off from the vent cap, thus allowing the vent cap to slide under the shingles. Installation is not difficult, however, if you’re not handy in doing this type of work, I wouldn’t recommend it because a leaky roof can be costly. I did apply a generous amount of roof sealant under the top and side of the vent cap. Didn’t apply any sealant under the lower end of cap to allow for any moisture to escape. The vent cap comes with a screen, which should be removed to prevent dryer lint from clogging it. Trapped lint may cause the dryer to overheat or lint to come in contact with the dryer’s heating elements and could start a fire. I give it a five-star review because it looks great, it appears well built and does what it’s supposed to do. So far, I recommend it.

A very well made product. Finish is well done. Usa made seem to be very durable.

Build quality is excellent. Install was a breeze during new roofing application. The collar is quite big so if you install it on a existing roof you might have to take out more nails than with an other brand. Use some roofing screws in black for the front of the vent for a clean look and make sure not to over tighten the screws else the rubber washers won't seal properly

Peachy, wonderful, fabulous, couldn't live without it!!!

This is very sturdy and well-built. The collar as other people have said is a little larger than I expected so I did have to pull out a few more nails. It looks great on the roof and I’m sure it will outlast my 30 year shingles.
