5.0 out of 5 stars Best roof cap for installing a dryer vent or bathroom vent that exhausts to the roof, May 9, 2010

Product is made to last and is easy to install. It is painted black and has a low profile so that it not noticable when installed on your roof. The damper works well and opens and closes without binding. You will need a drill with drill bit, roofing knife for cutting shingles, a 4.25" hole saw or reciprocating saw, a hammer, roofing nails, and roofing tar to install. If you are uncomfortable with heights or you do not have the proper ladder, leave this job for the professionals.

As a vent cap, this is a very good product. It is not flimsy or poorly made, and the color matches the roof perfectly. Other products are metallic in color and stick out on the roof like a sore thumb.

This vent is designed with rigid vent tubing in mind, as with a range vent. My application was for a bathroom vent. The old ventilator was much too noisy, so I decided to replace it. I found that the flexible vent, made of plastic, was pockmarked with tiny holes. I wanted to use flexible metal vent tubing that would last a while.

There is no provision for a vent that is not self-supporting in this cap. It merely fits over the end of the projecting vent on the roof, and does not "capture" or support it. My solution was to rivet several angle brackets onto a 6" piece of 4" vent tubing and attach it to the underside of the roof. Then I fit and clamped the flexible tubing to the underroof end of this. So, the flexible tubing was supported and held in place,...Read more

Several months ago, I purchased this vent for my master bath. Now, I am purchasing a second vent because we are upgrading a second bath. Product is made to last and is easy to install. Quality all-metal product. Durable and well manufactured piece of equipment. Great value for the price! I do wish it came with a collar for easy hookup of flex pipe. (Minor problem) I won't hesitate to recommend this one.
