If you are considering adding solar panels to your home, one of the first things you will want to do is check the condition of your roof. Rooftops that are damaged or nearing the end of their lifespan will need to be replaced before you can safely add a rooftop solar system to your home.
But what if only part of your roof is damaged? Can you replace only part of a roof? The answer is more complicated than you might think.
Can I Replace Just Half of My Roof?
There may be situations where your roof sustains partial damage – usually due to storms or fall trees. However, in most cases, it is in your best interest to do full roof replacement rather than a partial one. Doing so will minimize the chances for complications and preserve the aesthetics of your home.
Here are a few reasons why we recommend a full roof replacement:
The appearance of your home
The roof is an essential component in boosting the aesthetic value of your home. Replacing only a section of your roof can result in an uneven appearance. It will be challenging to match the exact shape and color of your existing shingles. Even if you are able to find an exact match, part of your roof will appear noticeably older and worn out by the sun and other natural elements.
Hidden expenses
Partial roof replacements aren’t as cost-effective as you may think. Full roof replacements allow you to purchase materials at bulk prices. Replacing only a section of the roof will usually result in a higher cost of materials and labor.
Partial roof replacements also set the stage for complications – such as leaks or sagging – that will result in additional repair costs over time.
The Logistics It Entails
Replacing only part of a roof can affect the integrity of the entire structure. Think of your roof as a single structure instead of something made from multiple parts. Once you start taking out sections and putting new ones in, the entire support system becomes weaker and the additional weight of a solar PV system may be too much to handle.
The Uneven Life Span
You end up with a home that has a roof with different life spans after a partial replacement. As a result of the uneven lifecycles, you will have set the ground for constant inconsistent work on your roof. The worst part is you do not get a warranty for a partial replacement like you would for a full one.
When Is a Partial Roof Replacement Acceptable?
Can you replace only part of a roof? Technically, yes. Should you replace only part of a roof? That is debatable.
Although we advise against replacing part of your roof in most cases, there are instances when it is okay. A partial roof replacement is acceptable when:
- A specific area that is less than half of your roof is damaged.
- A few individual shingles are missing or damaged
Partial Roof Replacement vs. Full Roof Replacement
It might be tempting to opt for a partial replacement to save a few dollars, but in most cases, the risks outweigh the benefits.
If you are asking “can you replace only part of a roof?,” the answer is technically yes, but we generally do not recommend it. Opting for a full roof replacement can save you from a lot of headaches and frustrations – not to mention expenses – down the road.
