You’ve had an interest in updating your roof but may be intimidated by where to start. It’s understandable, the roof is an extremely important part of your home and upgrading it may be costly. Can you lay new shingles over old shingles to save time and money, or do you need a full roof replacement to protect your home?
Finding the answers to some of these questions starts with identifying your needs. What is your purpose for wanting a new roof? Are you trying to fix leaks, repair damaged shingles, or is it more about aesthetics and updating the color?
There are many misconceptions about what you can and can’t do to your roof. But these don’t have to keep you from taking action.
Keep reading to learn whether you can truly shingle over shingles.
Can You Lay Shingles Over Shingles?
The short answer is yes. The more helpful answer is that, while you can, you may not want to in certain cases. That said, there are some scenarios where you can lay shingles over shingles. Start by considering your roof’s age and condition as well as learning the advantages and disadvantages.
If you have asphalt shingles (also called “composition shingles”) this could be a reasonable option. In fact, these are the only type of shingles where laying new shingles over old ones is possible. This is not recommended with other shingle types.
To decide whether this method would work for your roof, reach out to an experienced roofing contractor and have an inspection done.
Before making a sound decision, always look at the pros and cons. Typically, you will find the best solution by doing your research, talking with a professional, and weighing the good and the bad.

When You Should Shingle Over Old Shingles
While many roofing companies will not shingle over old shingles, some still do. It may not always be the appropriate choice, but in some instances, it may be an option that works for you.
If your roof is in overall good condition
Even if your roof is quite aged, if the underlying structures and sheathing are in good condition, you can reroof over old shingles. This is especially true if there are no leaks and there are no curling or missing shingles. An amateur may overlook structural damage or leaks, so always have a professional check for you.
Laying new shingles over old ones could get you a new roof with a shorter timeline than a full replacement.
You Want a Different Design or Color
Maybe you are renovating your entire home, and you would like your roof to match. Or, perhaps you just want to give your home better curb appeal.
Often, homeowners will update and upgrade their homes when they are trying to sell them quickly. If it is your forever home, a different design may be part of your plan as you work to complete your vision.
In either case, it may be possible to layer a new color over your current shingles for less time and money.
You’re Trying to Minimize the Cost of a New Roof
Putting new roof shingles on top of old shingles can be more cost-effective, at least in the short run. Roofers will spend fewer hours on labor and clean-up since they won’t need to tear off your current shingles. The smaller the mess there is and the shorter time spent on labor, the less you will be charged.
Otherwise, if you have your roof replaced, a large part of the cost goes toward labor fees.
You Don’t Need to Replace Your Entire Roof
The majority of your roof may be in good condition. If this is the case, it could make more sense to reroof the section that needs to be restored. Sometimes if there are more good shingles than bad, you can buy yourself some time by just fixing what is damaged.
When You Should Not Shingle Over Old Shingles
As you’re learning, there are a few cases where reroofing over old shingles is doable. However, there are times where it is impossible or will cause more trouble to lay new shingles over old ones.
You Already Experience Leaks
Though a common misunderstanding, adding more layers will not make your roof waterproof. Your underlayment is what protects it from water, and if that needs replacing, the whole roof does.

Your Roof Already Has Multiple Layers of Shingles
Roof structures are not built to withstand multiple roofs. Due to building codes, the limit is two, and even that second layer of shingles weighs it down. Often, roofs will already have two layers, meaning they are unable to structurally support more.
Your Roof is Curling and Shingles are Misshapen
If your shingles are curling or misshapen, it will do more harm than good to shingle over old shingles. The roof’s surface must be flat, or water can get underneath the shingles. Covering curled or damaged shingles will only trap that moisture. By not having the roof properly repaired, you may set yourself up for leaks.
You are Planning to Sell Your Home
While reroofing may seem cost-effective in the moment, it can become more costly in the long run. Some home inspectors will frown upon this method as they know that the roof may not last and may be a higher cost for the new homeowners down the road. This will not add value when trying to sell your home.
Laying New Shingles Over Old Shingles May Impact Your Warranty
Shingle manufacturers require their shingles to be installed according to their guidelines and specifications. Since putting shingles over shingles can shorten the new shingles’ lifespan and damage the roof’s overall structure, doing this may void your warranty.
