new roof installed, should I be concerned?

[disney]

Greetings. I would like the opinions and expert advice as to if this is normal, and I should not worry about it, or if I should ask to have them corrected.
My 'bigger' concern is that they used 4 different pieces of rolled roofing on the top pass, with the shortest being only a few feet long. (makes me think they ordered one less than they should, and just used scrap for the top row) The other is how this vent pipe is done, in theory, I do not think it would cause any issues, but I have never seen it done this way before, and I have been on a few dozen roofs (but not hundreds, or thousands like a pro would be) Please weight in, and have a wonderful day.

You probably won't have any problems in the short term.

But with roll roofing it should have the least amount of seams as possible. That transition from the shingled part of the roof to the roll roofing part is subject to a slight pooling of water as it tries to drain off due to its flatness. But like you said...they didn't want to buy another complete roll to finish it so it would have a seamless run. Was this roll roofing 'torched down ' ?

As for the vent...it will work and probably not be a problem. The part i don't like is they shingled it all the way around the vent stack. I always cut out the shingle part just in front of the width of the vent stack. Leaving the metal part of the vent showing. Lets water run off without debris getting caught on the shingle.

You could trim away that small amount of shingle yourself but i would ask for that top strip of patched roll roofing to be taken out and re-installed with a seamless piece.

Good luck...you did good in your inspection !

If the rolled roofing is "torch down" it's fine...(you rarely see the cold method any more)...The stack boot installation is kosher (and done well)

Both my stack vents are "uncovered" but I like the way they finished yours and can see no future problems with it being this way.

I'm not familiar with the use of roll roofing.

Agree with driver, Cut the shingle off straight down; then plastic cement down the tab. I would have suggested metal flashing in the transition.
Its a long run; but might be worth it.

All looks fine to me.

Normally there wouldn't be a shingle over the top of the downhill side of the pipe flashing, but having it there really doesn't make a difference as long as the flashing is sound.

I like seeing the old style lead boot...these days most are plastic with neoprene making the seal around the pipe...lead will last as long or longer than the roof (if the squirrels don't chew on them)...

If there is a question of debris collecting there should be a hardware cloth screen over the vent...I understand about the slight lip the cemented tab presents but I personally prefer the least conspicuous look...and sometimes both galvanized and lead boots will leach whitish streaks below the application...

FWIW...one of my pet peeves in regard to architectural appeal is seeing obnoxious vents stacks on the street side of residential homes...I always tried to work with both the architects and the plumbers to shift any vents to the rear rakes if possible...If there was no way to avoid it I'd ask the plumbing subs to cut the standard white PVC short and use a piece of black ABS pipe for the penetration and exposure...the black usually was much less noticeable to the discerning eye...

I agree with what others have said......the roll roofing has a lesser life span then the shingle section as it is and those extra seams are just asking for trouble as it ages......Jack

The laps on the rolled roofing appear to be torched down and the lower 90 degree corners cut to prevent the corners from coming up..Common commercial Mod bit roofing install as far as I can see..Also the lack of visible fasteners would suggest the whole rolled roofing system is torched.Cold process with torched lap's is still used widely though ,and once cured is still a good system.

The extra vertical seams will pose no problem as long as the installation was done properly..Also judging from the horizontal ridge in the background of your picture,the roof slope is more than sufficient to prevent pooling at the shingle and flat roofing junction..I would be curious as to how far they back lapped the rolled roofing up under the shingle layers..That would be my main concern in heavy ice and snow area's..And yes for your information I have been involved in commercial roofing/Sheet metal fabrication and installation for about 20 year's..

Living in FL; if I get heavy snow, I think we (as a nation/world) have a big problem...

I want to sincerely thank you, and everyone else who has responded to date.

I have not been given a final bill yet, and I wasted 1/2 day+ today as I had to be home for a permit inspection, only to have it canceled by inspector (on site) b/c contractor did not give/provide/leave required paperwork...

As the job took four days to do, and I was only home the first two (that's how long it took them to remove old shingles and put peel and stick down), I do not know how they actually adhered the rolled part. I do know that the (I'll use the term salesperson) Said I can go with the national company I was going to use, or I can use His company who will do a better job, and as they are busy, and do custom homes, they cost a little more. I was willing to pay a little more for a better job, but seeing as my neighbor used the national company, saved money, and does not have any seams in their rolled roofing, I can not say that I am happy.
