Can you put new roofing shingles over old ones?

October 26th, 2022

Picture it: You’re standing outside looking up at the bright, blue sky when out of the corner of your eye, you see something that look a little off. You grab your ladder, scale the side of your house only to find what you fear the most: your shingles are lifting. In fact, a few of them obviously flew off during the last thunderstorm.

It’s at this point that most homeowners start to panic and think that they’ll have to sell everything they own to afford a new roof because it’s impossible to lay new roof shingles over old ones, isn’t it?

Read on to learn more about re-roofing and how to go about it.


The first step is determining whether you can reshingle is proper roof evaluation. Although there are cases where the entire roof needs replaced, most other roofs can be reshingled simply by putting new ones over the old ones. This not only saves time, but labor costs as well.

Benefits of Reshingling

Laying new shingles over the old ones comes with a slew of benefits. From a financial standpoint, homeowners can save thousands when compared to ripping off an old roof with a new install.

In addition, reshingling also looks as good as a new roof would, upping the resale value of your home. And depending on which types of shingles you choose and the company who installs them, you could have an extended manufacturer’s warranty as well.

Situations When You Need a New Roof

Even with so many benefits of putting new shingles over old ones, there are times when it just won’t work. Since most building codes only allow two layers of shingles on a roof, laying new ones really may be prohibited. In fact, if it’s a commercial property, you might end up having to rip the roof entirely, if it’s fails inspection.

From residential standpoint, you’re better off replacing your roof if it continually leaks when it rains, feels spongy and soft or has gaping holes in it. If this happens, your roof may not be able to support the additional weight of the shingles. In fact, it could collapse.

To Shingle or Not to Shingle

Putting new shingles over the old ones is possible, however, there are also times when it just won’t work. If you’re not sure whether needs replaced, it’s always best to consult with a roofing expert instead of just winging it.
