Can You Replace Just Part of a Roof?

If you are experiencing leaks, it is important to fix the problem as soon as possible to prevent further damage. Some people may think that they can just replace half of their roof.

Even if you could, should you? Is it a good idea?

Can You Replace Part Of A Roof?

Technically, yes, you can replace just part of a roof. However, it isn’t something we usually recommend.

We aren’t saying that if you need a small roof repair you shouldn’t do it (you definitely should). If you have a single hole that needs to be fixed, for example, you may just need a small repair.

When it comes to replacing only part of your roof, however, there are some things to consider before you decide whether or not to do.

Reasons You Shouldn’t Replace Just Part Of A Roof

It Can Be Difficult To Match The Materials

If you have an asphalt shingle roof, the color of the new shingles may not match the old ones. This can be especially noticeable if your roof is more than 20 years old and the new shingles are a different brand or style.

The same goes with tile roofing. If you have a tile roof, it can be difficult to find replacement tiles that match the ones you currently have. This is because roofing manufacturers often discontinue styles and colors. Even if you are able to find matching tiles, they may not be from the same batch, which can cause slight color variations.

It Will Cost You More In The Long Run

By replacing only the damaged section of your roof, you can save money initially.

The keyword there is “initially”

The issue is, you may have to replace the entire roof sooner than you would if you had replaced it all at once. This is because your roof will have different levels of wear and tear, and the new shingles will not last as long as the old ones.

You should really think about how much you’re really paying for a partial roof replacement. Each time you replace half your roof, you’re paying for materials, labor, time, the contractor’s overhead, and more.

Depending on the size of your roof, you’re going to end up paying more in the long run per square foot than you would for a full replacement.

You might believe replacing half of your roof will save you money, but it will truly cost you more.

It’s Not Always Possible

In some cases, it may not be possible to replace just part of your roof. If the damage is widespread, or if your roof is nearing the end of its life, you may need to replace the entire thing.

It’s also important to keep in mind that most roofing warranties require you to replace the entire roof if even a small portion is damaged. So, if you have a warranty, replacing just part of your roof could void it.

You Won’t Get a Full Warranty

When you replace your entire roof, you will usually get a warranty from the manufacturer for the new materials. However, if you only replace part of your roof, the warranty will not be as comprehensive.

This is because manufacturers typically only offer warranties for their products when they are used in conjunction with other compatible products. So, if you mix and match shingles from different brands or styles, you void the warranty.
