If your shingles show evidence of wear, then you may be wondering if you can simply lay new shingles over the old ones. The short answer is that yes, you can put a new roof over your old shingles, however there are some factors you must be aware of prior to doing this. First, the new shingles will only be just as sturdy as the previous ones. Therefore, should your old ones be in bad condition they won’t be any better. Also, you should ensure that your new shingles are well-sealed and that they overlap with the old ones by at minimum 3 inches. If not, you could have the chance of leaking or other damage.

Take into consideration the age of the current roof
One factor you must be aware of prior to re-roofing your roof over current shingles is the current roof. Shingles have a lifespan of 20-30 years. If your roofing material is at the end of its lifespan It may be better to replace it entirely rather than re-roofing over it. Re-roofing old shingles could be an issue if roof shingles aren’t in good state, as this can result in the roofing material to fail more quickly.
Verify roof repair
If you’re thinking of re-roofing your home, one of the first things to check for roof damage. This is crucial because of a few reasons. First, you’ll need to make sure you have the affected areas fixed prior to installing new shingles. In the event that they are not, you may be left with leaks. The damaged shingles could be an indication that your deck’s roof is in bad shape. When this happens, you’ll need to replace your deck before installing new shingles.
Check local building codes
Before beginning your Reroofing in Lomita project, it’s important to check with the local building code to confirm that you’re allowed to reroof over the old shingles. Some codes might require you take off the old shingles before making the roof, and others permit you to put the new roof over old shingles.
If you’re not sure what the code is in your area then you should contact the building department in your area or the manufacturer of the roofing material you’re planning to use. They should be able to tell you what the code is and if you can reroof over your existing shingles.
Inspect the roof decking

If the roof decking is in poor condition then you’ll need to replace it prior to proceeding with the re-roofing.
Take into consideration the weight of the new roof
It is important to be aware of the weight of your new roof prior to re-roofing old shingles. The old shingles may not be able to support that weight, that could cause issues later on. Always consult with a professional to determine the capacity of your home to bear the weight of a brand new roof.
Check the ventilation
Before starting your project make sure you check the ventilation of your roof. This is essential to ensure that the new roof will be capable of breathing and will not hold in moisture. To accomplish this, you’ll need to remove all of your old roof shingles as well as felt paper from the roof deck. Once this is done, you should be able to observe the ventilation channels that are in place. If you are not able to observe them, you might need to install new ones.
