Minor damage to the 10 inch roof cap as shown in the pic. Cheap flimsy damper with a small riveted hinge at the back. There is a nice rubber seal, but this like all other roof caps looks like it will blow in the wind and be noisy. I intentionally chose a roof cap without a spring as this causes back pressure on the hood vent. The bird/bug screen fell out multiple times, upon arrival and when performing install. It is held in place by tension reasonable well if undisturbed, but may require being checked periodically. I hope that all joints are seam welded, as shown in one pic there is an easy opportunity for water to enter. I would like a response from roofing direct on this bad design feature, as I believe this flap should have been installed on the inside, not outside as shown. I will hose test and if I see a leak I will need to apply roof cement, and make this vent ugly.

Package arrived on time and packed well enough. No problems from the seller. The issues are with the product itself. While the bottom plate is wide to ensure good overlap with shingles (big plus!), the metal feels thin & easily bendable. I advise on extra water sealing around folds and bends too or this might potentially leak into the vent. The bird screen was also loose in the box and not attached to the cap. It’s not the easiest to reattach without potentially bending the cap, and no instructions were given on how to attach so I assume it was sent that way or it got knocked out during shipping.
Andrew, thank you for your feedback on your recent order with us. We are sorry to hear that the screen came loose in transit to you. Please reach out to us directly and we can provide you information on how to install the screen.

Product is pretty good except for the metal screen which fell out in shipment. This is a consistent problem mentioned in prior reviews which still hasn’t been resolved. The official response has been something like “ we leave it loose so you can clean it out in the future “. This of course is a BS response. I added 2 self tapping metal screws to secure the screen to the product so that the screen doesn’t come loose . The last thing I want is to have the screen loose up on my roof. Please fix your product!!!
Hi Robert, thank you for your concerns regarding the vent screen. These are secured from the manufacturer using a pressure fit design, however, they can become loose due to the intense rattling created in transit. Please be assured that these are not normal conditions that the vent would experience through its intended use and after installing you should not have any additional problems.
Perfiect .. well packed and all looks great
Thank you for letting us know that the product was packaged well and that it looks great.
