Instead of tearing the whole roof off, can I just put new shingles over the old roof?

best bet is to check with town building official as to the requirements in your state. personally, i would tear off the old shingles and do the whole roofing system over. there are a lot of new technologies in use today to better seal your home from water. ice and water shield is one, if you live where it snows. this has to go on the wood decking and will seal around the nails to prevent leaks. plus with a "clean" start your roof will be put together right and last longer. the cost of disposal of roofing is going up in many areas so doing it now will be cheaper. one other thought, next time you can go over it if you choose to. good luck and happy holidays!!

if you put new shingles over old it will cut down on the life expectancy of you new roof. Some manufacturers will void their warranties if you do not remove the old roof.
If removing the old roof is not an option, consider another material such as metal or fiberglass sheets.

Check with your state building codes first to see how many layers you are allowed but it is best not to go more than 3 -4 layers because of the weight issue.But take it from a construction worker it is always best to tear off the old one first that way you can make sure from eye on experience that all you're decking is good and isn't rotten so you don't have problems with sagging or wood rot. Do things the right way so you won't have to do it twice. Work smart not hard! Good luck:)

If you are going to replace the entire roof .you might as well do it right. That means tear it all off . down to the plywood . and put all new tar paper roof tabs and then shingles . you will come out ahead .

By most building codes you can have a total of three layers of asphalt shingles before you must tear all layers off and start over.

If you have 1 roof on their already,you can.If you have 2 roofs on it,you take a chance of wind damage & broken rafters,so if you have 2 roofs on it,it's best to tear it off.If youre uncertain about how many roofs already exsits,you can find companys to give free estimates,my husband is one...Randy"s Roofing if you would like to discuss this further e-mail me at baby_gail_1994@sbcglobal.net.

yes, but is better to tear it off and start over. how many layers are there now? too many and you will have issues with weight. also, if some blow off, such as in a storm, insurance company may not pay for total replacement.

you can if there is only one layer of shingles, but it would be best to remove the old ones first

Up to say, two layers, then the weight comes into question.
