Shingles Installed over old shingles

10 posts in this topic

Hello All,

I have a question. We have a smaller Cabin and i need to put new shingles on it. Can I install the new shingles right over the existing ones? We are planning on remodeling with in 10 years so then the whole roof will get redone. As for a quik easy install is it all right to leave the old ones on and go over with the new? If so, anything special I should do? I assume no tar paper?? Long nails i would think??

Thanks

If I were you I would go with metal roofing, it will go right over the old shingles with no problems.

I have never heard of laying another layer of shingles over old ones?

Under Minnesota code, you can not shingle over shingles. Every brand of shingle I've worked with also states that shingling over shingles will void the warranty.

Ya, I was not sure. A few people have mentioned to me to possibly do this for a quik fix for a few years BUT I have no experiance with it either.

Thanks

We put metal roofing over rolled roofing and it works great.

It used to be a fairly common practice. You can figure about a 10 year max life out of them.

I have them on my house right now and this fall they will be replaced. 10 years. I did it for a quick fix but ended up staying here longer than I had planned.

Not fun tearing off a double layer !

It will be easier to tear it off now, and tear it off again during the remodel, than it will be to pull two layers.

The code for no two layers is only in the hail zone. I have the counties listed, but I don't want to list them all.

As for the metal. It leaks, trust me, you just don't know it yet. It's a quick fix, but not a long term thing, unless it is just a simple two slope cabin that is rarely used. It will either leak or sweat eventually. I have a finished pole barn and I cringe when it rains because I know sooner or later I'll be ripping it all off and recycling it. Then I can put a real roof on.

Its only not code if your area has accepted new codes and lots of minn. isnt under current new codes but there is most likly a code of some type from the county.So it depends where you are.

It was just a few years ago a 2nd layer was accepted but not a third because of weight.Check county codes and if its OK, go for it.There should'nt be much problem for your short time,I have seen go overs last as long as new installs,

I have never been in favor of that practice. First, it adds too much soft cushion under your top layer. When hail hits it, it has a better chance of doing damage. When you walk on it, the shingles will flex too much and this too can cause issues. I've also heard that even though you use longer nails or staples, they are just not as secure and wind damage is more probable. It might be a quick fix but wait until the day you have to hire a contractor to remove a double layer. The cost can be considerably higher and as already mentioned, you won't save in the long run because the life expectency will drop a lot.

    • My only concern is the timing of all of this. We seem to be loading up for a run in the next year or two but the Warriors are still sitting there stacked beyond belief.  Can we add enough and develop our young guys enough to be a legit threat to the Warriors.  Lebron, Irving, and Love barely made the Warriors break a sweat in the finals.  I'd like to see them time their final acquisitions to correspond with the end of the Warriors run. 
    • Maybe line up all the non-compliant VW's and gas 'em all out with diesel fumes. 
    • Glad Lavine is gone! Added nothing but slam dunks to the team. I've been out of town for the past week, so I was very delighted to hear about this trade today.
    • Not unless they ban the toothpick crossbow here too. Takes those beetles out clean.   
    • That's called seasoning. Two years ago I took a trip to Germany and we spent a few days in the black forest where I got to see some authentic old world smoke houses dating back to the 1500's and the amount of buildup on the walls, hooks, poles etc is part of what gives their hams,bacon and sausage their flavor. They use juniper wood for smoking. Absolutely delicious.  But yeah, foil, Pam and other things can help. You can also use a power washer to clean them.
    •   "We have found they do not like limburger cheese, hot dogs, or Makers Mark bourbon.  I am thankful for that."   Thanks for making my nite.  
    • Also woodpeckers beat on stuff to mark their territory.   I am pretty sure that there aren't any bugs on my metal downspouts.
    • You will often discover that birds are picking very small insects from decks and other woodwork around your house;  they do the same with trees and any other structure that might hold the bugs. We see them often on our decks and they usually pick a little bit and then move on,  perhaps just checking to see if there is anything edible there. These rascals also love hummingbird or oriole nectar, sunflower seeds and of course suet in winter. We have discovered  many species that will head straight for the nectar for orioles or hummingbirds and also plunge their beaks eagerly into the grape jam bowls orioles love. Birds will eat a greater variety than you might think. We have found they do not like limburger cheese, hot dogs, or Makers Mark bourbon.  I am thankful for that.
