Broan 355BR 1200 CFM Roof Mount Powered Attic Ventilator, Brown PVC Dome Review

We purchased the Broan 355BR 1200 CFM Roof Mount Attic Fan several weeks ago. We needed the motor, fan, and temp control units to replace those parts that had been broken due to bad installation by the builder (or one of the many subs) of our home. The contractor who installed the original fan had screwed down the grounding screw with an impact driver until the screw was protruding out the backside of the temp control unit and in the path of the fan blades. It didn't take long for the blades to become notched and broken by the screw until the motor seized up. Since we have replaced it and installed the parts correctly, the fan has worked great; it has brought the temp down in our 2nd floor considerabily. The temp control is working like it should and I couldn't be happier with the purchase. A local electrical supply offered to have the parts ordered for us at nearly double the cost of the whole unit at Amazon. Shipping took about 5 business days (with free super saver shipping). Even the local home improvement stores didn't carry these and it would have taken 3-4 weeks and about $50-75 more than Amazon's price.

Broan 350B 1050 CFM Roof Mount Powered Attic Ventilator, Brown PVC Dome Review

I purchased the Broan 350BK to replaced an older attic fan that had burnt out over the summer. The Broan 350 was significantly lighter than the unit being replaced which made handling the unit on the roof a lot easier. The construction and materials used, particularly the base metal flashing, are quite robust and I like the 'brushed' look of the PVC plastic dome.
The installation itself is quite simple for anyone with modest carpentry (I highly recommend using the template which comes printed on the box) and electrical abilities. If you do choose to do it yourself, I recommend installing an isolation switch (available online or from your local hardware store) just prior to the fan so that it is not energized year round. If you have not done any roofing work before, I highly recommend getting a pair of adjustable roofing brackets and a long 2" * 10" scaffolding plank or board to provide a stable work area while working on your roof.
The unit has worked great since installation and there is a substantial difference in the air temperature in my attic, particularly in light of the high temperatures this summer.
One thing to note: unlike most older fans, this attic fan will run until the air temperature in the attic is 10 degrees below the set point. I have mine set to ~110'F so it will start to run once the attic temperature hits 110'F and continue to run until the temperature has dropped to 100'F.
