Ever seen these installed? A job we just finished

Correct. He is on the road all the time. too much for me, I hate to drive.

Nice looking roofs but J channel valleys are just temporary, leaves and debris will collect inside and damn it up. It will divert the water from the valley eventually with lots of trees sooner then you think. If your going to installing a lot I would suggest going with open valley systems, I have a hard time selling it as lifetime knowing the valleys will have to be redone in 10-12 years.

You had said that before Robert, and I appreciate the info. I asked my rep about it last time and he suggested not using open valleys unless your doing a batten system.

I thought I had mentioned it before, we just pulled a lot of j channel valleys and redid them in the 80s when I was doing aluminum shakes in Houston and saw first hand what happens over time. We would have a two foot brake on the roof to brake our shingles in the valley it was slower but finished valleys would be wide open for drainage.

Do they have the individual end caps for these or just j channel on the gables to? You can always do extra wide valleys in ice water or tile and metal underlayment we used tamkos on a tile roof awhile back.

This profile is very similar to the perfection shake which was oringally Alcoa's country shake shingle

It has a j channel for the rakes and a J channel with a cover for the valleys.

Gerard now promotes a filter for the valleys.

Decra has the filter too, also for their j-channel rakes.

Then the filters get plugged up! We ran into that years ago with the concrete tile. We made a big copper valley metal with a standing rob that the tile pieces butted against and it was nice and neat. the pine needles would get into the valley though and they would completely fill up those areas and make the water back up and leak. We had to take them apart and clean out the needles and the leakage would stop.

I know I have heard of people caulking the top covers to the lower so that the debris can't get in. On the other hand, when it does, it can't get out either. I don't know the answer. The same thing happens with shingles in a smaller way.

We deal with the needles-in-valleys problem here all the time. Here it's fir needles. Birch trees are a menace as well, all the various debris from them starts a compost heap in your valleys. We have had some luck (meaning longer time between cleanings) with 6 ribbed valley. The two center ribs are larger and form a center valley that can be open, if desired.

At least with the Metro's they are easy to take apart after the fact. We will see how they hold up.

TRG Repair? At least when we do one of them, it will be easy to repair if necessary as they will be straight. I don't think we will have many problems with them. Hey, sorry about the stroke. I guess they hit us all. 2014 was a bad year for me too. keep the faith!
