I have a dilemma.

Just had my house re-roofed. I did the tear-off, bought the materials and had a couple guys "who knew what they were doing" put the roof on. After the fact, I see that they used the fastening line on the architectural shingles to align the shingles. Which resulted in a not so straight roof which I can live with, however, what problems will I see down the road if it is left this way?

Thanks for any input.

Your shingles only have 4 nails per shingle instead of the 8 nails required by the manufacturer.........all the manufacturers.

What will happen? the shingles may get hot in the summer and slide down the roof. The shingles may blow off in a light breeze. The shingles may leak at the very top of the joints. The shingles will age much faster than normal and will experience curling and aging.


They obviously don't know about G-Tape, do they?

If they used G-Tape they wouldn't have had this problem.

Okay, here is a link to a gallery with 3 pictures of the roof that was put on 2 weeks ago. Again, the fastening line was used to align the shingles. There are 5 or 6 nails per shingle. From what I remember they were nailing just above the line.



Thanks again for any input.

One thing I noticed, they shot gunned or racked them. Wrong! They should have used the correct method of stair stepping them. I don't think those guys knew what they were doing, like they said they did. The exposure is not tremendously off, but I wouldn't be happy. It's probably not going to leak, but I would watch it. I hope they felted it. I think I speak for the majority of the guys here, hire professionals next time. It doesn't pay to go cheap on roofs. Sorry to here about your misfortune.

What Mupton said.
But if they did that to the field shingling, which is the easiest part of roofing, I would be concerned about what they did to the details. Chimney flashings, wall flashings, vents, valleys and stacks etc.

I was acually involved in the process from beginning to end but did not know at the time. Everything is correct. 2 rows of ice and water guard, the rest 15# felt. Chimney is flashed with step flashing and counter flashing. Solid flashing on top and bottom that wraps around the sides of the chimney. There was no wall flashings that they did, as I ended up doing the porches myself. The step flashing is 4 inches under the singles and 2 inches on the wall. Haven't put the couterflashing up yet, but will be cutting into the stucco to secure the counter flashing per inspectors instructions.

As far as the hiring a pro... couldn't afford it.. way to expensive... they wanted an arm also. I can tear off this screw up and redo the roof and not even come close to bids that I had gotten.

I guess my biggest concern would be whether or not the inspector will make me tear it off and redo it.

Thanks for the input.

Well with seeing the wonderful mistakes i can can honestly say again anyone chan shingle but is it right. Well i can assure you that this is a mess. Well the offest in pic 1 looks ok but the alignment is horrible. Pic 2 shows a vent way to high to the ridgeline. But it has a nice arc to it dont you think? Looking at these phots makes me wonder about the nail patterns. Since they layed it close to a 3tab i am worried they used the same did it worng that i see everyday. There is a 1/2 inch line on the shingles if the nail is not in that area the warranty is void and the roof is done wrong. Another concern is the pitch. It looks like a 2/12 and that shingle should not be there if that is true but pictures can be decieving. Could be a 3/12 but nothing more. Either way with that pitch Requirements are 2 layers of felt period. Sadly you have had a novice install your shings. Was his name smokin? Personally I would pull it off and redo it correctly. "Why cant guys read the bundles it is in english" A spoof from another link oh thats right they cant read english. Either way it is incorrect. And more than likely under ventilated.

Actually the pitch is 8/12, it is just how I took the pictures as I was trying to show how the shingles were aligned. The vents were left at the original locations. The roof only has 700 sq ft of floor under it and 4 vents.

Thanks for the input.

But is it enough? where do you live? base is 150 so with that you need 7.46666666664 vents and that means 8 since they are lamanco 750's. I follow the 150 rule out of michigan and yes i am branching out. If the house is older that 2001 it is not close to the correct amount

Local code is 150 unless they are balanced then it can be 300.

Again thanks for the input. I will take it in to consideration when making a decision as what to do. Again, who knows, if I leave it the inspector my make me tear it off anyway. From what I understand they can be pretty picky here.

I thnink you guys are right. It doesn't take much to understand the concept of roofing. Doing it is an entirely different thing. It is very hard, dirty work. This was my first and my last roof. Well, unless I don't have a better paying job next time around. I have a tremendous amount of respect for those who can do this on a daily basis. Especially on roofs steeper then 8/12.

Well if you have soffit vents you are ok then. The job should really have nothing to do with it. Think about your home, You take pride in it im sure of it. Your pay or job sould not make or break the job that is done to your home, it is yours and you need to live in it. Do what you will but i have seen too much stuff in my life.

the white line is where fasteners should go and not to align the shingles they seem to be overexposed the 5 and 5/8 recommended exposure should land you right below that double thickness you see in a lot of the shingles in pic#3

but i ll admit ive seen worst

seeing as it's an 8 pitch if the nails are not installed correctly the shingles might seperate.that is one reason for the white line it's for nailing not straighting it holdes the shingle in place.another question? did they use a nailing gun or hand nail? if they used a gun did they check the air pressure did the nails blow through
