Cut Valley: At Scro’s Roofing Company we install 98% of our New Roofs with a “Cut Valley”. Actually one of our signature pieces of our new roofing methods. We actually love the way it looks and believe it out performs all the other methods of roof valleys. What you do not see is how it begins, we first put down a 3′ wide layer of Ice & Water Shield (a sticky rubber membrane) in the valley that will literally melt down to the plywood roof decking and seal all of our nails. Also provides a secondary leak barrier. We then install the shingles to the smaller roof or lower pitch roof with new shingle 2′ onto the opposing roof. Lastly we apply a bead of roofing seal 1″ out of the center of the valley and install the opposing roof shingles into the sealant and cut to meet our straight line. We believe this smooth cut line aids in the assist of faster water shed out of the valley. This method of valley roofing is superior and very rarely seen by our competitors.
Weaved Valley: Are what is mostly seen from roofers that are concerned about going fast and not really taking the time to insure the problematic roofing valleys are installed correctly. It is also seen more in a thee tab roof installation which is preferable. We have seen many weaved valleys crack over time due to the extreme build up of shingle material trying to be forced into the small valley framing crease. It takes less time to install this type of valley and we do not typically install this type of valley unless the customer request it. Typically less expensive to install this type of roofing valley. Also in our opinion it just does not look as good as a cut valley.
Exposed Metal Valley: This is the most expensive way to roof in a valley. Mostly due to the cost of the metal and the labor involved in the custom fabrication and installation of the metal itself. Also we often see this more in higher priced residential homes and even using copper which also adds more to the bottom line. Using metal in the valleys is also used more in cedar wood shake roofing, slate roofing, clay tile roofing or even very high end asphalt shingle roofing that is too thick to wrap into tight valley areas of the roof. It looks very rich and nice but comes with a nice price tag that is usually frown upon afterwards. You can also choose from a variety of different colors of metal to compliment the color of your shingles.
Now that you have an idea of the different types of roofing valleys what would you prefer on your new roof?
