Can a roof have too much ventilation?

A roof can have too much ventilation if there are more openings for air to enter and exit the attic space than there is insulation and air sealing to keep the heat in the house. The heat loss from the house will be greater than the heat gain from the sun, and the house will be cold in the winter.

Duraflo 620808 Gable Vent, 10-Inch X 10 7/8-Inch Review:


5/16/18: Although it was 84 degrees outside when I checked the shed, it felt colder inside. I was pretty taken aback because I had anticipated it to be at least significantly warmer but not overly scorching. The shed faces east and typically receives direct sunlight till sundown, but now I can state with confidence that this product is effective!***Original Review***Our second shed is built of plastic and while it serves it's duty, there are no ventilation. As can be seen in the photo, installation was as simple as cutting a portion of the shed, inserting the vent, and fastening with four screws. Easy 10 minute job using a jigsaw and a screwdriver.When the temperature outside increases, the vent appears to be having an effect. The vent feels sturdy despite being made of plastic, and I believe the money was well spent!

BUD Industries IPV-1115 IP32 Air Vent, 3.2" x 3.2" Review:


I used this to vent a box containing my solar system's electrical components. The inverter instructions state that its operating range is restricted up to roughly 120 degrees Fahrenheit, yet it was getting up to 118 in the box. Ideally, it need to be under 104. I had to use a hole saw to create a 2.5 inch hole in the box in order to install this. The box melted around the cut as a result of the intense heat produced. If there isn't a rag nearby, you will have to scrape the meltage off when it has dried. A 60 mm fan was installed using 4mm screws. I'm using the charge controller load to power the fan. Today's temperature outside was 100 degrees, but the box reached 111 degrees inside, so the vent



Broan 433 Automatic Shutter for 353 and 35316 Gable Mount Attic Ventilator Review:


For installation in my garage, I bought this shutter together with a Broan 353 Gable Mount fan. After my wife and I return home in the afternoon, the temperature in my garage can reach above 100 degrees due to two hot engines that are generating heat there. Additionally, my neighbor, who came highly recommended, has an attic fan in his garage. With the exception of having to cut through an inch of plaster, installing the fan and shutter was therefore pretty simple. The shutter is quite excellent, however unlike what some of the other reviews claimed, they don't instantly and fully close themselves. It required a breeze to fully push them shut. As advised in previous reviews, I put some one-inch washers inside of each of the louvers, and it works fairly well. I really like this shutter, despite the fact that I have to fiddle with them to regularly close all the way. Due to my concern about the application of stucco, my neighbor also suggested utilizing Loctite Construction adhesive rather than screws or nails. Loctite performed admirably. With some oak that I painted white, I also utilized it to frame the shutters. I adore the shutter's appearance and would suggest it.



Da2430w 24" X 30" Aluminum White Gable Louver Review:


It's not as robust as I had anticipated, and the screen is already incorporated into the louvers, so it doesn't need one. Still, an excellent product overall, and a reasonable deal for two of them. The mounting holes do need to be drilled, but other than that, they can be installed in five minutes.



Duraflo 621212 Gable Vent, 12-Inch X 12-Inch Review:


exactly as promised. Excellent plastic side vent for a garden building that had six indentation screw hole guides on the back. It does include a flange, which I found to be quite useful. It protrudes through the thin wooden walls and makes a fantastic template for the cutting. A bead of caulk added all around the corner perimeter where the flange meets the outer "frame" made for a good tight seal. Once fitted, it looks neat and tidy as well.



Cool Attic CX1600 Gable Mount Power Attic Ventilators with 4.5-Amp 60-Hz Motor and 14-Inch Blade Review:


Functions as promised. A fan is installed in the garage ceiling to force hot air from the attic of a 1500 square foot ranch-style home up through the gable vents. Simply mounting the L-brackets on the opposite side from where they were intended allowed me to do this (opposite pre-notched squares). To enable the fan to be installed flush against a 3/4" board, four new holes had to be drilled and an aluminum sheath notch had to be cut. Fan reduces attic temperature by 10 to 15 degrees in 2 to 3 hours with thermostat set to 105 degrees. Despite having a hard switch wired into the circuit, I usually leave the fan running for a few hours to let the built-in thermostat regulate how long it runs. I've seen reviews where the quality of the thermostat is criticized, but so far, nothing has gone wrong. My kitchen has an additional conventional light switch, making it simple to turn on or off a fan from within the house as needed. Additionally, although there is some noise made by the fan in the garage, it is hardly audible inside my house. In summary, I am extremely happy with the fan's construction and functionality and am convinced that it is keeping the house cool and so lowering the run time and energy consumption of the main air conditioner. In my two-car garage, I have the good fortune to have two windows. I have safety locks installed on both tracks for security and until I determine where to put a permanent air vent, but I am leaving these open by about six inches for air intake. May want to remain with this strategy for the time being as the fan will be used only during the summer. I'll eventually install a vent simply in case the garage windows are closed and the fan activates.

PacTool International SA904 Gable Scribe Review:


This gadget works fine. It didn't work out so well when I tried to use it earlier to measure the angle for my trim. Hopefully it will work better once I install the siding!UPDATE: I've finished the one side of my garage where I really used this stuff. This product really is fantastic. However, I feel rather foolish because I was unaware that it glides through and does both the left and right sides. I initially thought it was poor design because the screw is dimpled and won't come out, but it's actually the user's fault. I'm delighted that I unintentionally discovered that it glides through on both the left and right sides. each and every time. I appear to perform even better work than the majority of siding crews.
