Can You Replace Only Half a Roof? - RoofClaim (2023)

Homes have many components and many homeowners pay a lot of attention to the interior, exterior, paint color, and doors. However, your roof is one of the major parts of your home that needs ample attention.

Extending the lifespan of your roofing is of utmost importance. Though this may depend on the materials used and the environment, maintenance can also affect the roof’s durability. Over time, your roof will deteriorate due to wear and tear. This is when roof repair or replacement comes in handy.

Some homeowners look into less expensive ways to solve roofing problems. One of these is a half-roof replacement. The question is, can you replace only half of the roof?

Is it a Good Idea to Replace Half a Roof?

While you can replace only half a roof, it is not recommended by roofing experts. Some homeowners might look at it as a cheaper choice–or think it saves time. From an expert standpoint, half roof replacement often brings more harm (or expenses) than good.

Why do experts disapprove of the idea of half-roof replacement? We’ve compiled four of the most common reasons why it’s not a recommended choice.

  1. Aesthetics

The way your roof looks is a major consideration in why you should not opt for a partial roof replacement. Even if you match the other half of the roof with the existing roofing materials, it will still show signs that one half is old and the other is new.

Furthermore, you cannot copy the same color as the older half of the roof as it has gone through wear and tear already, and it will not be uniform in color.

  1. Durability

Look at your roof as one entity. Replacing only half of the roof will have an effect on the other half. You are putting the reliability of your entire roof at risk. The support of your roof might already be brittle, and a half roof replacement could risk the integrity of the entire roof.

  1. Lifespan

Replacing only half of the roof can lead to an uneven lifespan of the roofing structure. While the new half has a long lifespan, the other half already has wear and tear. Keep in mind, once you perform a half roof replacement, you will have to do this over and over. Once the older half gets damaged or worn out, you will again take a half roof repair.

  1. Cost

If you think replacing half a roof is cheaper, you may end up regretting the decision. Because your roof is basically cut in half, you may experience leaks and other issues. Also, if your roof caves or you have serious damage, your insurance company will likely not cover a full roof repair, so you’ll have to shoulder higher expenses to get your roof repaired.

Roof Repair Versus Replacement

Can You Replace Only Half a Roof? - RoofClaim (1)

Some people insist on getting a roof repair when they need a replacement, often because budget is an issue. Choosing between roof repair and roof replacement should depend on your unique situation. At, our roofing professionals help you determine the risks and consider your options before making an educated decision.

People often get overwhelmed and confused about which method to use for fixing their roofs. Some tell-tale signs that you should consider roof repair or replacement include:

Consider roof repair when:

  • Shingles are cracked or curled
  • Shingles are wet, moist, and dark-colored
  • You see signs of shingle granules in the gutter
  • Signs of damages on the roof parts and openings
  • Peeling of paint on the roofline
  • Stains and signs of water in the ceiling
  • Roof leaks after a heavy rainfall
  • A sagging roof deck

You need a roof replacement when:

  • The roof is extremely old
  • There are visible missing shingles
  • You have damaged or missing flashing
  • Animals can pass through your roof or ceiling
  • The roof is caving in
  • The roof became damaged due to accidents or harsh weather conditions

But suppose you don’t fit in the categories above. Can you replace a portion of your roof? Yes, you can, but it’s only recommended if you fall into one of the situations below:

Lost Shingles

Can You Replace Only Half a Roof? - RoofClaim (2)

It is normal to lose a few shingles every now and then, especially if there are strong winds and heavy storms. While a few missing shingles due to wear and tear and damage is not a major cause for concern, you still need to contact a professional roofing company to figure out if there are more damages in other areas such as the decking or underlayment.

It is fairly easy to slot new shingles into the areas that need repairing. While it is a bit difficult to find the exact same shingles as the rest of your roof, doing this can extend the life of your roof without spending a lot of money. We can help you find the best solution to replace lost shingles while maintaining the integrity and look of your roof.

Minor Damages

Damages that do not cover a large portion of your roof can often be resolved by patching and using sealing products. However, you should still call a professional roofer so they can conduct a complete inspection and determine the best solution.

Roof Replacement Options

When you need a new roof, it should be done as soon as possible to prevent further damage to your home. But since replacing half a roof is not a trustworthy idea, here are the options you should explore.

Complete Roof Replacement

A complete tear-off and replacement is highly recommended by many roofing specialists. This removes all the issues that you experience with a half roof replacement. With this option, you get a whole new roof with new shingles, flashings, deck, and underlayment.

In addition, your new roof will have a longer lifespan, bringing protection and security to your home. Moreover, it makes your property look more aesthetically pleasing on the outside.

Added Roof Layer

Putting on a second layer is another option roofing experts recommend in certain situations. Here, another layer is added to your existing roofing. In case your old roof gives in and gets damaged, a new roof is already in place.

Compared to other options, this method offers a less expensive roof replacement alternative. It also requires less labor compared to a complete roof replacement. Furthermore, it doubles your protection from heat and other weather elements and helps prevent leaks.

Metal Roofing

This type of roofing material comes in vertical panels or shingles similar to slate. They typically last up to 60 years. Metal is excellent at warding off heavy rain and snow.

It may also acquire dents from hail.

Slate Roofing

Slate roofing can last for around 100 years or more. It is fireproof, waterproof, and mold and fungus resistant. Slate is ideal in wet regions. However, it is costly, heavy, and can chap easily when walking on. If you live in an area that experiences hail, slate may not be the best option.

Clay or Concrete Tiles

Built-Up Roofing

Built-up roofing consists of asphalt layers, tar, or adhesive applied underneath an aggregate. It is only applicable for flat roofs. Gravel roofs and tar roofs are compatible with rooftops with heavy foot traffic. The downside to it is that it can become sticky during hot seasons, and it is more difficult to eliminate snow from these roofs than smooth surfaces. They can last for about 20-25 years.
