I have a ranch home with a section of an "added-on" garage with a flat roof that needs repair.
I have gotten several estimates to have the entire roof done. Rip up the old shingles and replace ice guard and what ever else they do.
The last guy that gave me an estimate states that I dont need to rip up the old shingles on the whole house. Repair and replace the flat roof the rest of it just put new shingles on.
Is this wise? It's certainly cheaper and will look just as nice when finished? I need help please!!!

A professional roofing crew can rip off the old shingles in no time, thus the cost to do this is very small to the overall cost, but worth it. Your new roof will have a much better appearance, and the overall weight on your tressles will not have undo strain them on them, which can cause warpage and really degrade the appearance of your home.
Removing the old shingles also permits the opportunity for the sheathing underneath to be inspected and pieces replaced if rotted. (even though your roof may not appear to be leaking, sometimes water will get though and old roof and begin to rot some of the wood sheathing)
A decent shingle will last for 25 years. Don't cut corners. Few a few dollars and piece of mind for 25 years. Treat your home right.

I'd have it all ripped off and replaced. Even though your roof might not leak, the under layer of shingles probably have some curl to them and it will transfer through to the new shingles so the roof won't be as flat as it should be.
Also, when you "repair and replace" the new shingles don't exactly match the old ones. So, there again, you can really tell what's been done and where. I had to repair some shingles on my house before I sold it and I thought it looked horrid, but the new owner got "new shingles" and now she'll have to see the patch for the next 10 years until the rest of the roof needs replacing.

it seems that you got alot of very good answers but it seems alot of them forgot what your question was!
if the rest of the house does not need replacing don't
my recommendation would be to put fiber board over the shingles on the garage roof and then .060 rubber this would be the litest and the easiest to tie into the main house roof
buy the way the BBB isn't for you
get some references
make sure you get a minium of 10yrs for your warranty
also ask your contractor about a warranty strait from the manufactor
this will ensure that it is done right because a roof inspection will be done by some one from the rubber company

I was a Roofer for over 10 years, it is common practice to just shingle over old shingles. If your roof now is not leaking then this is a good idea, the only reason to have the old shingles torn off would be because of a leak and water damage of the plywood under the shingles. one word of advice though, do not use cheap shingles. Speak with your contractor, most can get you good deals on shingles, and with the money you are saving by not having to pay for tear off and clean up, you will have extra money to spend on shingles. Good luck with your home updates.

You can have up to 3 layers of shingles on your home without having to remove to replace. Are there any indications of leaks under your house roof? Best way to find this out is to go into attic space and look for leak rings. Flat roofs are not a good idea for any part of a home in high snow areas. The weight of snow could actually end up collapsing the structure. Would it be financially possible to replace the flat roof with a peaked one, to bring it in line with the rest of the house? Remember that this would require a permit!

I agree a lot with the above answers. But one thing that no one mentioned is "get references". And does he have insurance? And what type of warranty does he offer on the shingles and labor, and get it in writing. And also get it in writing the date the job will be completed. And it would be a good idea to check out the Better Business Bureau on this person or company. And very important do not pay for the job until it is completed and that you are happy with all of it including the clean up.

My dad was a carpenter for over 40 years. He knows that the trend now is to rip up the old roofs, and he doens't agree with it. His feeling--and he did excellent work--was that this is not necessary if you've only got one layer of shingles on there now. I'll bet this last guy is from the "old school," and I think you'll be fine if you let him do it the way he wants.

Roofing last longer when it's a single roof. Also the warranty is based on one roof, not on several. Multi layers of roofing hold in heat and decrease the life of your new roof. If it's worth doing, it's worth doing right. It's your house, but I'd do it the best way possible. Good Luck

The new roof can be installed right on top of the old roof, but there are several considerations, or "replacement triggers" which have to be looked at:
1. Building code requreiments
2. Roof deck condition
3. Ice dam protection
4. Vapor retarders and ventilation
5. Is it a recoverable system?
If all the crtieria is met, you can recover the exisitng system without reducing the quality of the new roof.

depends on how old your roof is. some might say that just because you have one layer of shingles its ok to put on another layer. that is totally wrong. putting on another layer just adds more weight to your roof increasing the chances it will collapse. layering is cheaper but you get what you pay for. think about it. what will make you feel better, after all you will live there
