Customer Questions & Answers

How much wind speed is needed to get it to turn?

Asked by: cb
Barely any. There was a slight breeze when I was installing mine and the turbine was already moving.

How many do I need and is this okay to use with lots of rain?

I'm hoping to get these for my 1008 square foot one level ranch style house (roof slope is fairly normal). How many of these do I need to properly ventilate my house? The current ventilation is not sufficient. Also, I live in the Pacific Northwest where it rains pretty much every day during the winter. I haven't seen any of these on other houses and am wondering if they are good to use in this area. Lastly, what other materials do I need to install one of these? We would be putting a new hole in the roof to install one.

First rain mine encountered, it leaked like crazy! Seems to be poorly designed. It's too flat, not enough slope for the rain to runoff, and no type of seal to keep water from entering at the top and running down the main shaft. Stay away!

What is the circumference around the bottom edge of this spinning turbine?

I'm trying to figure out if I can replace the old head with this one
Asked by: Tony
The circumference is calculated by multiplying the diameter 12" by PI (3.1416) = 37.699"

Does it have a fan built into the device?

This is probably a dumb question but i am new to the market and was wondering if it had an internal fan that would suck air out of an attic?
Asked by: jonsmith
The heat from your attic makes the turbine spin and it pull the heat out of your attic

12 in. Galvanized Externally Braced Replacement Turbine Head is rated 4.0 out of 5 by 87.
Rated 1 out of 5 by from Bent out of shape It arrived bent out of shape. Did not work as well as the one I wanted to replace. Returned it to the local Home Depot.

Bought one of these to replace an internally braced one that was wobbly and making noise, but not leaking. Installed easily. Didn't spin easily. Rained the following day. Took a peek in the attic and this thing was leaking like crazy! Water was coming in through the top underneath the triangle-shaped piece, you see in the picture, running down the main shaft and dripping rapidly. Droplets of water were also collecting very heavily on the inside of the "fins". Rushed to remove this one and put the old one back on, since at least that one didn't leak. Couldn't return this thing fast enough, I would avoid these like the plague!! Probably would be better off just eliminating this type of venting from roof altogether, more hassle than they are worth.

Very quiet in operation and I don't miss the grinding noise of my old units! Shipping was convenient and arrived as expected. One of my 3 units was damaged in shipping but I contacted Home Depot and a replacement was immediately shipped. Returned the damaged unit to my local store for credit and process was very painless. I would recommend this product from a cost and quality standpoint and kudos to Home Depot for the great customer service from start to finish.

The only negative was the long wait to get it shipped to the store

The Master Flow turbine head works great and was relatively easy to install. I thought that I had purchased the wrong one (external/internally braced), not knowing much about turbines, but I only had to drill new screw holes to make it work.

Rated 4 out of 5 by from Good value, looks like they are built to last. The old light weight turbines had been damaged by a hail storm. These are heavier gauge galvanized metal. It looks like they will hold up under hail and wind better.
