Nice Design Purchased 18 vents for the attics of our townhome complex. We chose these since they claim to be tested to 200 MPH winds since we live on the east coast. However, we have some leaks, which appear to be due to the installation. The roofers did not look up the instructions online, and just used a roofing nail in each corner. It appears they need to go back and add screws like the instructions show. If this fixes the problem, I'll upgrade the review grade.

Custom vent for greenhouse The custom vent was exactly what we needed for the flue on the furnace vent in the greenhouse. A size that was not readily available at the stores here. Prompt manufacture and delivery was another issue. The date promised with the purchase and the delivery were anything but smooth. It finally arrived days late and the only thing that saved the job was that the installers for the repairs to the greenhouse were also delayed in finishing the job. Things worked out but not without some good antiacids along the way!!!!!

after 13-15 years they still perform like it was day one i bought of pair of Active Vent retrofits -- 13-15 Years ago (!) to replace those useless turbine spinners -- i noticed brown spots on my ceiling - surprised to discover they were letting in rain and they were in good shape and spun fairly fast. i just took out the spinners - fit these retrofits in - they fit just right - fastened the standing vent pipe with some galvanized screws - easy peasy. Fast forward to 2019 - they still look great although the label has faded from being exposed to the sun - They do not let the rain in - and i live in the NYC area which saw back to back hurricanes - Irene in 2011 and the devastating Hurricane Sandy 2012. These retrofit vents will prob out last me.

wrong part right treatment I ordered a vent cap to be painted. I received an unpainted one. Upon notification active ventilation immediately refunded my money. Sometimes it goes wrong but they made it right. That is my kind of company.

03/21/2019 03/21/2019, I emailed roofvents.com some pictures on my kitchen, bathroom and roof vent. Later spoke with Ethan half hours on the phone. At the end,Ethan offer his expert advise on what I really need and don't need, without pushing to sale anything to me. I REALLY APPRECIATE HIS HONEST ADVISE. I will recommend this company to anyone as they are honest people. I was going to buy some replacement vent and hoping it will fix my problem but Ethan said I would do it but will not solve my problem. Thank you!
