Homeowner Forum / Construction / August 2005Re-sealing asphalt shingles -- OK?
I live in Florida and I have a 10 year old roof that sustained some hurricane damage in the September 2004 storms. Roughly 1/4 of the shingles on the roof have lost their seals -- IE you can stick your finger underneath them and lift them up off the roof. The past several months of unusually hot weather, even for this region, have not caused the shingles to reseal, indicating that they probably are not going to. The roof has been inspected by several professionals, all of whom agree that this is wind damage. There is a discrepancy, however, in the recommended method of repair. Most of the roofers say that the shingles in question need to be replaced, and that due to the large number, the whole roof ought to be replaced. The insurance adjuster, citing a GAFMC installation manual, says that all of the shingles can be hand-resealed with plastic cement. He provided me with a few pages photocopied from this installation manual as proof of this. I read through the information he provided, and it describes a procedure for hand sealing NEW shingles that had never been sealed. But it does not address, one way or another, whether hand-resealing is appropriate for shingles that have been torn free by wind, as these have. In other words, his evidence doesn't really back up what he's saying. Therefore, I'm looking for some information to either support or refute the adjuster's claim, since what he provided me does not appear to do either. Is it acceptable to repair a roof with the damage I've described by resealing all of the loose shingles with plastic cement? And can you point me to any official documentation so indicating? Thank you in advance. Tony >I live in Florida and I have a 10 year old roof that >sustained some [quoted text clipped - 46 lines] > indicating? > Thank you in advance. This sort of thing is often not documented.. but might well be workable, try a few and see. how long term the plastic cement is, is another issue. I would call the shingle mfgr myself. Phil Scott > Tony My roofer says that he's done this on other houses, and that it seems to hold for 3-6 months. This seems consistent with what the GAFMC documentation *did* say. In the section labeled "when is it appropriate to hand seal shingles", they mentioned when it is cold, and when blow-offs occur before the shingle has sealed on it's own. It's not spelled out so as to be irrefutable, but it almost sounds like they're describing the plastic cement method as a temporary, secondary mechanical fix designed to keep the tar strips touching the layer below until it gets hot enough for them to seal. Anyway, workable isn't what I'm looking for. My fear is that the insurance company is trying to use this as a way to get out of replacing the roof. Their obligation, legally, is to make the roof "like it was". One adjuster says hand resealing with plastic cement will do that, and all roofers say that it won't. Each has interests that could be behind what they're saying to me, so I don't really feel that I can completely trust any of them. That's why I'm looking for objective information, preferably in writing. Thanks for your response.

If the shingles are laying flat and just not sticking to the shingle below, using roofing cement in a caulking gun is a quick way to seal them down. You can also use roofing cement and a margin trowel but it's slower. If they're not laying flat it's a bigger deal. The roofing cement won't hold them flat until it dries, so you'd have to weight them down. Whether it makes sense to do it in your case would depend on the conditon of those ten year old shingles. R Have a look at a product called "Re-Roof". It is a new product that can add 10 years to your roof. Also consider the roofing cement and caulking you will want these products as well. These are all DIY's. When dealing with professionals such as an insurance company you will likely want to go with the professionals opinion.

My main problem is that the professionals are not all of the same opinion. I'm trying to find some kind of objective information that doesn't have me relying on the opinion of anyone with an agenda, one way or the other. Any advice along those lines? Tony > Thanks Tom.

If the shingles aren't damaged and they're laying flat, the roof cement will work. There is no doubt about that, I've done it many times, albeit on a smaller scale. If you're looking for some irrefutable information source on gluing down ten year old shingles loosened by wind, you're not going to find it. It sounds like you're looking for some assistance in arguing your case with your insurance companies adjuster. Private adjusters typically are veteran insurance company claims adjusters who have gone freelance, and have expertise in negotiating property claims to make sure you get the most out of your policy. R What does your insurance guy say? If they are going to pay then it will be up to them what work they will cover. I have done roofing professionally and I do not have an agenda! The pros you have/will be talking to will naturally want to know what the insurance company will cover and they will also want to get as much of that money as they can. Getting an estimate from your adjuster will be your first move likely! Hope this helps! Let me know if you have any more questions! Tom : Thanks Tom.

Roughly 1/4 of the [quoted text clipped - 27 lines] > > About 15 years ago, I installed a skylight above a very dark stairwell in my 20 year old home. My roof was shingled with Johns Manville Midnight Black shingles. I had no spare shingles and I found out that J-M no longer made that color, so I had to carefully remove the singles in the area that I was going to install the skylight. After installation of the skylight and flashing, I replaced the removed shingles around the skylight and then used a caulk gun with a black tar-like shingle adhesive to reseal the shingle tabs and edges along the flashing. They have been glued down for 15 years now. Of course, I live in NY where hurricanes don't happen very often, but we have had a couple (the last one being Floyd in Sept. 99, where I lost a 50' wild cherry tree).  SignatureBill |
