New Roof...is this normal for 2 layers.

Thats definitely a rake edge. Like plug said, if that starter on the rake is out like an inch or more like it looks like, then those shingles will more than likely bend down over the rake. That wont look good. I like my rakes to extend about 1/2''. It looks good and gives the shingle good support. I like to put new drip edge all around as well on a lay over.

I also agree its never a good idea to add a second layer. A lot of the times people do it because they are going to be selling the house soon and its for cosmetic reasons, but its not really fixing a lot of the problems that occur.

 

As for Gregs question I have noticed that the top layer tends to dry out and crack after around 10 years..So yes it most certainly cuts the life of the shingles dramatically

Thank you everyone, I will pass this information onto my friend. I appreciate all your help.

 

I wish I new about the 2 layers being not such a great idea. I had my roof done about 9 years ago by a local company that's been in business for about 30 years. They gave me a 10year warranty on labor and 25 on shingles. My roof looked good from day 1, but it started to leak near one of the valley's about 1 year later. The company came right over and tried to fix it by putting in a new liner down the valley and it didn't work. Turned out once we used a garden hose on the roof that it was actually a nail that popped about 10ft from the valley. It's been good for about 8 years now, but what a pain in the butt trying to figure that leak out, They probably came over 3-4 times before they found it. If I was to do it all again, I'd have piad the extra $1500 and have the first layer ripped off and start from scratch. Hopefully the roof I have lasts another 10 years. Only time will tell, but I'm happy with the job now. It still looks great to me. I didn't have any of the cosmetic wavy stuff like my friend has. Different companies also.

 

Thanks again for all your insight.

Jay

Mind explaining what a "Sealer strip" is ? headscratch.gif

 

I always used a 1" over hang all the way around with the starter and roof courses to the edge of the starter usually about 1/8th inch less makes for a better visual from the ground (less ragged edges ) , drip edge all the way around.

are you going over your old roof or are you stripping it down to bare plywood, i would never go over an old roof on my own house, start from scratch it will last longer,

View Posti probably should strip it..any idea how big of a dumpster i would need if i striped it?there is about 12sq on the roof.

 

12 squares, you would need no more than a 15yrd dumpster, you actually could get away with a 10yrd if they have one,probably less than 1500 lbs of weight with only 12 sqr's, good luck
