I am from Missouri and just had a roof installed. I previously had two of the flat vents, and two turbines. Now I only have two of the flatter vents on my roof. They must have roofed over my two turbine holes. On my order/contract it said, two flat vents and two turbines. I'm very ticked. I haven't contacted them yet today, but would like to know first just how serious this is. I heard that these vents help provide air circulation in your home and to let out the hot air in the summer months. Is that so, and am I justified to create a little stink about this?

To clarify, I did not recieve those hidden ridge vents, it would've been nice, but no. Also, please do not answer unless you feel you really know. Thanks.

It's more about preserving the life of the roof. It helps reduce the moisture on the underside of the roof. If your attic didn't get good circulation, then you would have condensation forming on the boards that your shingles are nailed to. Ventilation prevents the condensation by keeping the temperature in the attic basically the same temperature as the temperature outside. If the two temperatures are different, that's when condensation occurs in the attic. This would cause mold and the boards to rot or wear out much sooner. As long as the new vents provide adequate circulation, you should be fine. If the turbines aren't needed, it will make the roofline look nicer. However, you should definitely check to make sure that you weren't charged for the turbines and their installation if they didn't install them and make sure that the ventilation they put in is adequate. I'm assuming they put in ridge vents. The ridge vents most likely will provide enough ventilation. I just wouldn't like getting charged for something that I didn't get.

Attic ventilation is primarily to dilute the warm moist air that leaks out of your house into the attic in the winter. The cold roof deck allows this warm air to condense on the rafters and decking. This will cause mold, rot and possibly ice even dripping. Venting was not an issue before insulation as there was plenty of air/heat moving from the house into the attic. Once you start sealing, insulating and separating the attic from the conditioned space this became important. The primary way this helps shingles is rot, mold and mildew. Look at any shingle warranty.

Attic vents work well in a balanced configuration - equal amount low at the eves and at the ridge - this creates a natural draft. "Extra" vents at the ridge don't help much if there is not a place for an equal or nearly equal amount of air to enter.

Do attic vents help keep the attic cooler in the summer? To a very limited degree yes. But not enough to add life (years) to shingles. Unvented or encapsulated attics with spray foam insulation or SIPS panels are very common. Shingle life is not significantly different between the two types - vented or unvented - actually the roof orientation has a bigger effect. Predominantly S and W facing shingles will age and dry before N and E shingles. Why? Direct solar gain. The temperature on the roof surface is 165+ while the underside can be 140. Anybody been in an attic in the summer? It's hot right? By my infrared work any where from 120-140.

The purpose of venting the attic is to keep the roof deck near the same temperature on the outside and the inside. This is best accomplished with soffit vents to take air in at the bottom and ridge vent to let the air out at the top. This causes fresh air to move along the entire bottom face of the roof deck to efficiently maintain the temperature. Ridge vents are the way to go on any ranch, given that there is proper intake on the soffit. I would not use metal ridge vents, simply because of appearance. There are several options available in plastic or fiber rolls that are designed to have shingles applied over top. You see very little of the vent so they blend in quite nicely and matching the color is not a concern. Other venting options are required when you have a complicated roof design, often you can't get enough ridge to get adequate ventilation. You don't have that problem, so a ridge vent is the way to go. If you are dead set against any kind of ridge vent, 7 750s on the back should get you enough volume, just not the even coverage.

Roof Turbine Vents

The turbine vents would definitely be to remove hot or moist air from the attic or crawl space. You don't want humidity building up to the point that it starts to condense on surfaces. It can cause mold and rot and in some cases, with high humidity like you get in Missouri, can actually start dripping on to the top side of the ceiling or insulation. Every attic has to be vented, no matter where you live. So if they didn't vent it, yes, I would be pissed. The other vents would be for your plumbing system.

If you just got a new roof... then they probably installed ridge vents along the peaks (extra cost)... Many roofers say they are just as good as power and turbine vents... but that's not totally true... What is true is that the roofer gets to also charge more for "repairing the holes" with new plywood or press-wood... So you just have to beware and know what to expect...

Vents are to keep the condensation out of your attic. Ridge vents are good, thats what I have on my house & I'm very happy with them. The flat vents are usually used to vent your plumbing system, ie:septic, toilet. If they didn't replace your turbines then you probably have no ventilation for your roof & it won't last long. I would defineitely *****.

By all means call and BITC*! First of all, the contract says two turbines. And in the second place, you need as much air circulating from the soffits to the peak in order to get the maximum lifetime from your shingles.

Yes you are very justified. They should not cover up these vents as they provide air flow. Make a fuss and get them to put the vents back.

It is to help vent heat from the attic space.

Without vents, the life of the roof will be shortened drastically.

I do not know enough about roofs to say whether the two static vents will be enough or not.
