## Description

This 084633 Black Metal Roof Vent Cap is designed for use with range hood and bath fan exhaust. It is 26 gauge galvanized steel with a black powder coat finish. This 6-inch version includes a removable 1/4 x 1/4 inch screen and a built in backdraft flapper. Builder's Best black metal roof caps begin with galvanized steel which has some corrosion protection. The high performance polyester powder coating shows very little corrosion when subjected to the ASTM B117. These roof caps have been tested for 480 hours (20 days) with a sodium chloride (salt) solution to accelerate a corrosion process. (ASTM B117 tests conducted by a third party lab. ) These roof caps performed much better than the leading brand (painted steel) and a foreign brand (painted galvanized). The Black Metal Roof Vent Caps are built in the USA by Builder's Best,

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

*by L***O on 8 November 2018*

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
