New roof did not pass inspection

Good luck @Fiona…as a contractor I wouldn’t blame you at all. As you said…you can always hire a lawyer to defend you if they choose to come after you. You have the pictures and documentation to back you up. Get a Certainteed shingle installed by a quality contractor…preferably “Shinglemaster” certified and I’m sure you won’t have a repeat of your situation. I agree with @MPA…Can’t go wrong with Landmarks…:+1:

Thanks everyone. I will post a picture of my new roof when I get it replaced. Another thing that struck me odd about the current contractor is that they wanted to do this repair in January. Could they have possibly lifted shingles to check the nail pattern with it being so cold? I told them that I want them to pay for another roof inspection after the repair. I have not heard from them yet on this. Something tells me that they really don’t plan on addressing the overdriven nails.

Just wanted to update that I had a full home inspection done this weekend. I wanted to be on the safe side after the tornado. This home inspector clearly pointed out that the flashing around the chimney was done incorrectly and my shingles were not laying down because of the improper installation of the felt. He also said that the sheathing was stapled instead of nailed (has been this way since the original roof installation in 2002.) Should the sheathing be nailed now or are staples still acceptable?

Screws. Staples no longer meet code anywhere that I’m aware of for roof shearing.

I don’t know of anybody that uses screws to attach roof sheeting, everybody I know uses 8d pneumatic driven steel nails.

I’m not a fan of staples but they do hold pretty good and guys tend to use way too many of them.

Yep, why would you use screws when you have 8d ring shank?
They never come back up.

I also have never heard of anyone screwing down roof sheathing on a residential roof.

In my area only nails 8d or greater are allowed anymore. Personality I have never nailed roof sheathing, one builder I worked for 15 years ago used to staple wall sheathing, but still always nailed the roof. Staples hold up ok on in my experience until you tear off the shingles. Every time we run into a stapled deck we always end up shooting it down with nails before installing the new roof.

So when I replace this roof, I will discuss about getting 8d nails in place of the staples. That could be part of the problem with the roof now.

The home inspector also told me that he doesn’t recommend replacing large sections of shingles to repair this roof because the new shingles will have a different color appearance from the existing shingles, something about they have different lot numbers.

We use exterior decking screws on all our redecks for the last 5 yrs or so. Always know if you miss…won’t ever rust…and guaranteed not to back out. Staples work great…but don’t meet most codes.

So to update everyone, the new roof installation is in progress and no issues seen so far.

What did we find out about the first bad installation?

#1 #30 felt did not have enough caps installed. This was causing the bulged shingles and wavy roof.
#2 Sheathing was not nailed down properly after first tear off.
#3 Chimney flashing was installed incorrectly.

For the new shingles that have been installed, no issues with bulging or wavy roof. Yay!!

What I don’t understand about the first installation, good starter shingles were used. Drip edge was good quality, Even the felt was good quality. Why would the contractor or roofer try to go cheap on the shingles and hired labor? He could have prevented future legal issues and this could have been a good outcome and good review for quality work. What a waste.

Why, he used cheap labor and materials was to make more money. We compete against guys like that every day. Why they use subs is so they do not need to pay workers comp.

We explain to customers upfront that our bid is going to be more expensive than some competition. Our estimatoras explain that we do not use any sub contravtors, only use top grade materials, replace all flashing with every job, only use copper on masonry walls, etc. A smart educated customer understands that and want the best job, others just want the cheapest price and we move on.

There is a local radio ad running for some company claiming to do all residential roofs in one day. I don’t know how that would appeal to anyone who has any clue about roofing, details take time to do correctly and should not be rushed.

After the tear-off of the new re-roof, we found out that some sheathing was replaced during the first re-roof. I noticed that there are still some bulges in two areas after the new installation. The new shingles hide it much better though. I reviewed pictures that I took of the sheathing during the tear-off and this was where sheathing was replaced during the first re-roof. Could this sheathing have been warped? And should the second roofer have done something about it? I have talked to him and he said it is not going to cause any problems. The new shingles hide it pretty well so I can live with it, just want to make sure that it won’t be a problem later.

Hey Fiona! Sounds like it looks a lot better!

I had the same experience. A roofer who said he’s been doing roofing for 30 years. He charges a premium price and just hires the cheapest labor he can find, and he doesn’t inspect the work. I have to inspect it myself and then tell him what’s wrong. Shoddy workmanship and it is annoying.

I’m curious to what you do for a living Robert.


I’m an engineer. Desk job type stuff.

Hey robert2018. Sounds just like my contractor. Do you live near Houston? It might be the same company.

That sounds like a lot of contractors these days unfortunately…

Sorry to hear that. Hopefully my delayed response does not find you to late. As far as the contractor slicing felt it would not be warrantable or advised by any reputable company to shingle over sliced felt. However, it would be acceptable if their intentions were to install another underlayment over the entire section were the slices were made. Following protocal as if they would have taken the existing felt off just installing over the existing sliced felt. In fact this would provide more of a buffer that could help with impact resistance and provide a two ply waterproofing membrane. That would be win win saving them the time of removal and providing you more protection.

Good luck, Sorry the experience has been negative. It really is embarrassing for the industry. I have made a career of protecting customer and contractor alike. Although I have not found a way to successfully target the residential market showing the value until the job is complete.

Seeing as you’ve revived the thread, the bulging deck is caused by nailing the ends of the sheet, then nailing towards the center. Instead of nailing from one end of the sheet and forcing it to lay flat, it forces a bubble in the center.
