This vent works great! We sell a ton of them to our customers and they exceed our expectations. Always in great condition and look extremely sleek after installation. #sweepstakes [This review was collected as part of a promotion.]

Works well
Product works great. Shipping on the other hand has issues. We had to return 2 before we got one we could use.
It's letting the rain in !
The roof cap looks great, BUT I had a leak in the bathroom. The driving rain shower we had yesterday caused some rain to enter the duct - presumably because the backdraft damper failed in some manner. This is first hard rain we've had since the November 2017 installation so the leak was a new experience.
Thank you for taking the time to review your 634M roof cap. Dripping water is either condensation (usually due to cold ductwork or improper duct installation), or a problem with the seal on a wall or roof vent. Insulated ductwork can help solve condensation problems, and running the fan longer will ensure moisture is completely removed from the duct. Ductwork should slope down toward a wall vent to direct condensation out of the exterior vent opening rather than back into the fan housing. During very stormy or windy/rainy weather, you may have some incidental blow back. Should you have further questions, please give our Technical Support team a call at 800-637-1453. We would be happy to help you more if we are able too. Thank you for your feedback and for your Broan purchase.
