Last week I had a roof installed on my ranch (low slope). Complete tear off and replace shingles. The way the house is built, the roof peaks are in the shape of a lower case "t". (Without the curly tail.)

The roofer installed ridge vents on the long part of the "t" but only the rear half of the cross of the "t".

In my opinion, all of the peak should ridge vents. Also, the contract stated: "Install cap over venting ridge to roof peak as per manufacturers specifications."

I would appreciate an opinion as to whether it is necessary to vent all peaks, and whether my contract requires the contractor to do so.

Thanks very much.
