Asphalt shingle roofing question: How exposed is an "exposed nail?"
My house just had a complete roof tearoff and application of 50 year
architectural asphalt shingles over 30 lb. felt and 1/2" CDX plywood. The roofers finished last Friday, and I see some exposed nails and they presumably replaced some shingles, therefore. Going up there now I see more exposed nails. Some I can see standing over them, maybe half of the nail head (1.25" galvanized roofing nails). Many more, I can see from the side, if I look up the slope of the roof. I figure those are less exposed than the ones you can see from above, but some moisture is going to reach those nails too. How exposed does a roofing nail in this circumstance have to be before it presents a problem? Thanks for the information. Dan |

Asphalt shingle roofing question: How exposed is an "exposed nail?"
You should not be able to see ANY portion of the nail. Think of it
this way, if you can see it, so can the rainwater. Each row of nails should be completely covered by the next row of shingles (except the top row, and that'll be covered by a ridge cap most likely). Do not let the contractor tell you any different. Take lots of pictures, keep any documentation (contracts, work receipts, etc). |

Not only is too low a concern, but shooting off-line too high is a concern.

Of course, this was the only one with everything spelled out, using the exact materials. I followed up on the lead, and Bruce said if I would cut it closer to a $400 difference, he would award the job to me. No can do Bruce, you know the work, go ahead and take your chances. A couple months later, Bruce called me. He said he was embarrassed to call me, but didn't know where to turn. He climbed on the roof, and seen nail heads between the rows. He asked me to come look, and he would pay the fee. No charge to this fella, I had to see what he was talking about. He then asked me what it would cost, to fix the problem. Well, the roofer had two complete rows, disappear when he got to the ridge, this was besides the hundreds of shiny heads that could be seen. I told him, the quote was still in the computer, and was still good. We ended up, tearing off the brand new roof. And, Bruce, well he took the company to court. But, the company went belly up. |

Asphalt shingle roofing question: How exposed is an "exposed nail?"
Exposed nails must be sealed. I just put 11 squares of arch. shingles
on my new garage. I am not an experienced roofer and used a nail gun. I took my time but wound up with 5 halfway exposed nails, plus 2 for the final ridge cap shingle. I used roofing cement to seal each nail and the cap. I would be ticked if there were 70 and I paid someone else. |

It would be interesting to know the length recommended for the 50 year laminate for which you have. I don't know. I suppose 1.25". From the Prestique Plus spec sheet on elkcorp.com: FASTENERS While nailing is the preferred method for Elk shingles, Elk will accept fastening methods according to the following instructions. ALWAYS NAIL OR STAPLE THROUGH THE FASTENER LINE. NAILS: Corrosive resistant, 3/8" head, minimum 12-gauge roofing nails. Elk recommends 1-1/4" for new roofs and 1-1/2" for roofovers. In cases where you are applying shingles to a roof that has an exposed overhang, for new roofs only, 3/4" ring shank nails are allowed to be used from the eaves edge to a point up the roof that is past the outside wall line. 1" ring shank nails allowed for re-roof. STAPLES: Corrosive resistant, 16-gauge minimum, crown width minimum of 15/16". Note: An improperly adjusted staple gun can result in raised staples that can cause a fish-mouthed appearance and can prevent sealing. Fasteners should be long enough to obtain 3/4" deck penetration or penetration through deck, whichever is less. Cheers, Wayne |

Asphalt shingle roofing question: How exposed is an "exposednail?"
I would be very interested in knowing who the roofer was, especially if
in Florida. We had the same shingle, similar problems with sloppy installation. I've posted details about it previously in AHR. We had many, many shingles nailed off the line - there is NO margin for error, as ours delaminated and fell off. Many were cut and pieced improperly, so the overall pattern is haphazard. Roofer used regular shingles for ridges, which also looked like crap. Elk used to have install requirements and warranty applications on their website, but which were taken down for a time. There is a form to be filled out and mailed to them for warranty - I would not count on the roofer to have done it. I believe the warranty is void if not installed according to instr. I learned, from our mess, a good deal about roofing that I had never expected to learn. Our condo board did nothing for a long time, and in the meantime the replacement value declines. They should have hired an attorney right away, as the shingles fell of in numbers. Still falling off, but not often, and after two major reworks. This shingle is worse on steep roofs, we have mansards, and the city now requires a spot of cement under each tab on mansards. The outcome of all of our grief is that the darn things stayed on pretty well through last year's storms whilst most buildings in the area lost shingles. The estimator told me they roofed with integrity, did the job right. They appear to take a lot of pride in correcting mistakes, so maybe they will correct these. How do you correct an exposed nail? How many shingles do they have to pull and replace and how? How many in a given area before it makes more sense to pull the whole area and replace them all? Thanks for the help! I am not much for lawyering up, but this is a job that seems worthy of an attorney handling construction defects. No way should such slop get a pass. Just for good measure, I would file a complaint with the agency that licenses the city building inspector who signed off on the job. My town has some real bad practices, and they just might have saved a life or two if they did a better job. I am very serious and pretty familiar with some awful professional practices. I bitched to our city manager about code issues, with no results, two years ago. Right now, we have a section of rotted atrium roof beam propped up with jacks = when it began to sag years ago, some genius put in two sections of downspout between the atrium ceiling and railings to hold up the roof!! Work is under way to replace the beam and jack up the sagging roof. A condo across the street has had work being done on roof and exterior walls for the past 6-7 months - apparently rotted out walls. And it is a neighborhood with investors rabidly buying in and avoiding maintenance to make a buck. PS I was wondering if there's any way to repair at least some of the exposed heads (maybe the ones down flush and barely showing). I'm probably naive, but I thought that maybe inserting a small rectangle (1.5" x 2") of thin stainless steel with sealant/adhesive under it over each exposed nail might make a permanent fix that would last decades.

I read your post that mentioned the cap a day or two later and it didn't ring a bell, so I suspected that they'd cut for cap. Dan, the brand of cap won't sabotage the perfomance of the covering. I'm just anal about aesthetics, some people probably wouldn't notice, even if/when it was pointed out. I probably notice this practice, because I'm in the business, and it rubs me the wrong way. I see that. I have a 3 tab shingle in the room with me and can see that the overlap is barely more than an inch. Not all the shingles look the same, by a long shot, but this one has a whitish line at about the midway point in the overlap, and I assume that's the nail line and I guess they should really be on that line, not so much as a 1/4" below it or the nail can be seen, at least from the side. I was thinking maybe they did nail on-line, but used the nail line, to align the bottom of the shingle? I believe Elk has a 5-5/8" exposure (you would have to check me on this). The bottom of each shingle should be aligned to the "cut out" of the previous shingle. But then again, since I've seen off-line nailing by the hundreds, nothing surprises me. Also, not just online nailing is important, but placement of the nails. Example- 1" in from each end, and 1 foot in from each end (or manufacturer recommendations). You don't want nails any closer than 2" from butt end of shingles. I'm wondering how I'll know if they did a kludge and reused the shingles with holes in them or replaced them with new shingles. I guess I could get up there on the roof and watch them like a hawk, but I was trying to avoid that scenario. I suppose I was engaging in a lot of wishful thinking when I put so much trust in these guys. This is my first contract in my life. I was hopeful but I'm taking my knocks now. I'll find out what they say this morning, the estimator (who I think is also one of the company owners, probably, or at least a higher up), and the project manager who I'm going to call in an hour or so. Being anal like I am, I probably would take a can of fluorescent spray paint and mark each bad shingle. That way I would know which ones they replaced, or should've replaced. I'm not suggesting you do this, but just something I would do. The estimator told me they roofed with integrity, did the job right. They appear to take a lot of pride in correcting mistakes, so maybe they will correct these. How do you correct an exposed nail? How many shingles do they have to pull and replace and how? How many in a given area before it makes more sense to pull the whole area and replace them all? Thanks for the help! Well, with as many goofs as you explained, I hardly believe for one minute, that they roof with integrity. No one should have that many mistakes on one roof. The damaged shingles needs replaced, nothing less would do, for a newly done job. I would not settle for sealant of any type. To replace a shingle, you need to pull the fasteners from the shingle/s above the bad one, plus the fasteners in the bad one. PS I was wondering if there's any way to repair at least some of the exposed heads (maybe the ones down flush and barely showing). I'm probably naive, but I thought that maybe inserting a small rectangle (1.5" x 2") of thin stainless steel with sealant/adhesive under it over each exposed nail might make a permanent fix that would last decades.

Asphalt shingle roofing question: How exposed is an "exposed nail?"
Roofers often hire inexperienced help as "nailers". You sure had some
poor nailers on your job. You should see no nails except at the very end of the top cap. There is probably a lot more wrong with your job. Better have it inspected by a professional. |

Asphalt shingle roofing question: How exposed is an "exposed nail?"
The project manager came by today an hour after he sent out a couple of
guys with some shingles, who repeatedly shook their heads at what they saw and started replacing shingles. I stood on the roof and watched them work. I could see that they were replacing shingles. The process of removing nails from the shingle above has me worried. It seems like that will damage the roof. Also, nailing with a hammer in that circumstance looks iffy, like they can easily damage the shingles. They have to lift up an edge of a shingle to nail down the one below. I don't think the younger guy is very experienced and the older guy seems tired, way too tired to be a regular roofer. The project manager comes by an hour later and declares that nails that you can see from the side are OK, particularly on a low sloped roof. I'd think it the other way around. He says they'll only replace shingles with nails you can spot from directly overhead. He also declared my north dormer 4/12 and therefore the single layer of underlayment is sufficient. I told him I measured it at 2.71/12, but he said he'd measured it 4/12. I insisted, so he got his guage and measured and he said it said it was 3/12. I said the instructions on the package clearly indicate that this requires double underlayment. He said it wouldn't leak and I said it would after a few years. He changes his tack and says the double underlayment in under 4/12 sloped roofs is only for when you use 15 lb. felt and they'd used 30 lb. felt. To this I said I'd reread the instructions. Here's the instructions verbatim: " UNDERLAYMENT Apply underlayment (Non-Perforated No. 15 or 30 asphalt saturated felt). Cover drip edge at eaves only. ICBO requires No. 30 underlayment for re-roofing over wood shingles. For low slope (2/12 up to 4/12), completely cover the deck with two plies of underlayment overlapping a minimum of 19". Begin by fastening a 19" wide strip of underlayment placed along the eaves. Place a full 36" wide sheet over the starter, horizontally placed along the eaves and completely overlapping the starter strip." To me, that means they didn't do the job right. Am I wrong? I told him I had a mind to have the roof professionally assessed and he said go ahead. I called one of the estimators I had bid the roof and he called me back and said their fee is normally $300. He said that after they finish their repairs today if I still want to to call him back and he'd come out and do the inspection. Is $300 too steep for that? I can call some other local roofers. The project manager said the crew chief that did the job hasn't gotten compaints before and he doesn't know why this job turned out so bad. He admits that when he came back to replace badly nailed shingles he seemed to have done "nothing." I'm afraid that I'm not going to wind up with a long-lasting roof job here. The roof looks a ton better than it did, all the sagging is gone, or almost all of it, but if I have leaks I'll be bummed. Their warranty is for 7 years. Of course, the shingles are 50 year. Maybe I should try to get the Elk rep over here. Thanks for your help. Dan |

Asphalt shingle roofing question: How exposed is an "exposednail?"
I don't know whether the actual shingle has changed, but the sales pitch
has. 10 year longer warranty (attractive to homeowner), fewer nails required (attractive to installer) - since all of the disasters, they are probably cranking out shingles as fast as they can. 50 year? The replacement value goes down with time, used to be on the website. Keep an eye by your downspouts after it rains and see if you see piles of granules. |

I have been in court for testimony, on more than one occasion. First, before you have anyone come out, and assess the project, make double sure, they have qualifications which will stand up in court. Otherwise, you're throwing your money away, again. Qualifications should include at least five years in the profession. Licensed, bonding (if required), and insurance. Any roofing certifications from manufacturers, such as Master installer etc. A list of projects and permits pulled within the last five years. I can't speak for other areas of the country, or even in my state. For my area, an assessment would include detailed & typed documentations of the problems, with photos & labeling provided at a cost of $150.00. Actually going to court, providing sworn testimony, or questions/answer sessions for your attorney/others, or any other incurred time, would be additional, @ $60 per hour plus expenditures. If you already have a family attorney, I would put in a call to them, for advice on exactly where to proceed before spending anymore. |

The guy I called is from a large reputable roofing company. I haven't checked them out in detail, but will before I hire them for an inspection. They were the high bidder on the job and their bid looked it - fancy packaging. They, too, were recommended in the local area Good Service Guide along with about 4 other roofers, including MY roofer! : :I can't speak for other areas of the country, or even in my state.

Sounds expensive to take this to court. : :If you already have a family attorney, I would put in a call to them, for :advice on exactly where to proceed before spending anymore. I don't have an attorney, but my sister (who lives close by) probably does or knows of them, or can get a good recommendation. I don't know if he'll budge on the side-seen nail heads, but he changed his mind about the double underlayment on the low sloped dormer (about 500 square footer). He called and said they WOULD tear it off and apply two layers of underlayment (maybe a second on top of the first, I don't know) and put new shingles on top. Hopefully, this time they will nail them right. I think it might still be a good idea to have that inspection. It is apt to turn up some other things they could fix before I pay them. So, even if the report doesn't figure in a court case, I can use the findings to get the roofer to fix problems. They seem to be willing to fix things when I make problems apparent to them. But I don't know much about roofing, so a professional inspection seems to me to be worth the money, even if it costs $300. |

Asphalt shingle roofing question: How exposed is an "exposed nail?"
On Sat, 12 Nov 2005 23:18:09 GMT, Dan_Musicant
scribbled this interesting note: an, you're right. Also, you shouldn't be able to see heads of fasteners :PERIOD. Does that mean from overhead or from an angle? The PM contends that if you can only see it from the side, it's not of consequence. See my earlier post about the surface tension of water and how it will curl around the bottom edge of the shingle. On a 4/12 pitch, I've seen water marks on shingles up to an inch above the bottom edge of the shingle above. Those fasteners will get wet. Over time that moisture, with repeated freezings and thawings, will move those fasteners around a bit and eventually they will leak. Absolutely and with no other questions asked I will tell you they will leak. On the other hand, if you have a seven year labor warranty, what the hell? If you get any leak whatsoever, this fellow is liable for it. Any problems ought to show themselves in that seven year time frame. Ask him if he will be liable for consequential damage like interior painting? Right now the owner of the company is on the defensive and of course he will deny, deny, deny. That being said, it sounds like he might just be firing one of his crews because they screwed up this job so badly. You will find that you will get better service if you become his friend rather than his enemy. At this point he knows his crew messed up a simple job. He knows his good name is on the line. He should want to make it right, and so far as he is able at the moment, he seems to be doing that. But be firm. There are likely other problems you can't see right now that will turn up over time. Keep his phone number handy...you will be needing it later... -- John Willis (Remove the Primes before e-mailing me) |

Asphalt shingle roofing question: How exposed is an "exposed nail?"
Two to 2.5 cents inine from this peanut gallery:

Also, you shouldn't be able to see heads of fasteners : :PERIOD. For sure! From ANY direction. I can't find it, but there is a spec on how/where nails go in shingles. Anyone know it? : : Does that mean from overhead or from an angle?

If you get any leak whatsoever, this fellow is liable for it. Umm, he doesn't sound like the kind to rush right over to take care of any future problems; he can't do it right the first time, has time to do it over partially now, but I wouldn't bet on later on. He just doesn't want to bother. : Any problems ought to show themselves in that seven year time frame. : Ask him if he will be liable for consequential damage like interior : painting? I suspect this type of person wouldn't feel liable for any consequential damage at all, including the inside attic debris, etc.. :... Somewhere I saw a comment that legal action wouldn't be worth it, but I disagree. If he won't make it right before he calls it finished, I'd say take him to small claims court, depending on the max you can sue for there. Around here it's $6,000, and that 6k would not only pay for the inspection the OP discussed, plus the repairs, but maybe even a beer or two afterwards. It's also a lot easier to win in small claims courts as a generaal rule. If the contractor values his business at all, he'll stop before he has to get to court and take care of things. He won't like the bad PR that could scrape up for him. OTOH, you can't be an a_hole about it, either. If it hasn't already been done, someone should get up there with a camera and take pictures of the problems, with at least one of the pictures including that day's newspaper for "proof" of the date the pictures were taken. That would be usable in most small claims courts; they like pictures. : But be firm. There are likely other problems you can't see right now : that will turn up over time. Keep his phone number handy...you will be : needing it later... .... or sooner. g. If all this info is correct, that guy's doing the same stuff to other people too, so he should be stopped. Gives the whole industry a black eye. : : : -- : John Willis : : (Remove the Primes before e-mailing me) HTH, Pop |

Asphalt shingle roofing question: How exposed is an "exposed nail?"
"Dan_Musicant" wrote Does that mean from overhead or from an angle? The PM contends that if you can only see it from the side, it's not of consequence. Dan, This person is yanking your chain. You're not supposed to see the fasteners from any angle. I suggest you read the warranty, posted on Elk's site. Your warranty is void, when not installed correctly. You can read the installation procedures, also on their site. In bold letters, it states: "Always nail or staple through the fastener line". It also states exposure is 5-5/8", with the nail line at 6-1/8". There's not a lot of margin for error, when installing these shingles. This is why I would also be concerned of placement of fasteners, with a proper distance from the seams. |

In bold letters, it states: :"Always nail or staple through the fastener line". It also states exposure :is 5-5/8", with the nail line at 6-1/8". Yes, the nail heads themselves are very nearly 3/8 inch in diameter. So assuming the nail line and cutouts of the shingles are accurately placed and that the nail is driven dead on the nail line, there would be a tad (1/64th inch, approximately) over 7/16 from the bottom of the overlieing shingle to the bottom edge of the nailhead. Whether or not you can see that nail head depends a lot on how raised the overlieing shingle edge is. All this varies from shingle to shingle. I can try again, but yesterday the project manager didn't want to replace a shingle on the basis of whether a nail in it was visible. He said it had to be visible from straight over it, looking down at a 90 degree angle from the shingle. : :There's not a lot of margin for error, when installing these shingles. Also, a lot of the nails are at a fairly (obviously) pronounced angle, because the nailer was in such a hurry he couldn't be bothered to adjust his position when nailing the entire shingle. Many are not flush, either. Some stand up, I'd say, a good 3/16". : :This is why I would also be concerned of placement of fasteners, with a roper distance from the seams. That's another area where I think they are guilty. They fired away a lot of times, putting easily double the number of fasteners in a shingle as if they could correct their errors by firing in more nails. I'm concerned about another thing right now. The project manager gave his two men instructions early yesterday afternoon to remove all the shingles from the north dormer, which is the 20' x 25' less than 3/12 sloped roof that requires double underlayment. They left the current layer of 30 lb. underlayment. I can understand doing that overnight to leave protection against any possible precipitation (although there's none in the forecast). However, I doubt that this existing layer of underlayment should be left on there before they proceed. The manufacturer's specification is for overlapping double underlayment, not one layer on top of another. Here's what it says on the shingle package: " UNDERLAYMENT Apply underlayment (Non-Perforated No. 15 or 30 asphalt saturated felt). Cover drip edge at eaves only. ICBO requires No. 30 underlayment for re-roofing over wood shingles. For low slope (2/12 up to 4/12), completely cover the deck with two plies of underlayment overlapping a minimum of 19". Begin by fastening a 19" wide strip of underlayment placed along the eaves. Place a full 36" wide sheet over the starter, horizontally placed along the eaves and completely overlapping the starter strip." Maybe I should print that out and hand that to them when they come in the morning, although it wouldn't surprise me if the person in charge wouldn't comprehend it. If they try to put a second layer of underlayment over the existing one, it won't be to specification and the lower layer will have hundreds and hundreds of nail holes in it to boot. |
