As a homeowner, one question that you’ll inevitably face is: repair vs replace roof. Do you patch up a few missing shingles, or does it warrant an entire roof replacement?

Minor issues can often be repaired, while major problems may require a complete replacement. Always consider the age of your roof and the lifespan of roofing material. Older roofs approaching the end of their lifespan or showing signs of deterioration may be better candidates for replacement.

In this post, we will unravel the pros and cons on repairing or replacing your roof. We’ll also share some insights on roofing materials like asphalt shingles — such as how often they might last in cases of replacement. Tresnak Roofing offers licensed and insured roof experts, who can adequately assess whether your roof is a prime candidate for replacement or simple repair.

Factors to Consider When Deciding to Repair or Replace

When deciding whether to repair or replace your roof, consider factors such as the extent of damage, age of the roof, cost, and future maintenance.

Extent of Damage

Assessing the extent of damage is a fundamental step in deciding whether to repair or replace your roof. For minimal issues such as a few missing shingles caused by a heavy storm, quick and less-costly repairs are usually sufficient.

However, when major problems like persistent leaks, extensive water damage or structural deformities due to long-standing wear appear on an old roof deck, they signal deeper-seated concerns that simple fixes might not resolve fully.

Age of Roof

Consideration of your roof’s age is fundamental in the “repair or replace” decision-making process. On average, the lifespan of a standard asphalt shingle roof tends to range between 15 to 30 years.

If you’ve recently installed new roofing materials and perhaps only have just a few shingles missing or loose due to high winds or minor damage, opting for repair work might be cost-effective instead of going for an entire roof replacement.


Taking into account financial factors is a fundamental step when deciding between roof repair and total replacement. Looking at the national average, a roof replacement project typically costs around $11,500 but can vary between $5,700 to $12,500.

On the flip side, if your current roof has minor damage or missing just a few shingles due to high winds or ice dams for instance, opting for repairs could be more cost-effective.

These small-scale fixes range in price from about $120 to $2,500 per job depending on severity⁠—a clear distinction from the heftier price tag that comes with entire roof replacements.

However tempting saving money may sound though, always consider future maintenance costs as well.

Future Maintenance

Considering future maintenance is crucial when deciding whether to repair or replace your roof. While repairing a damaged section of the roof may seem like a cost-effective solution in the short term, it’s essential to think about the long-term maintenance requirements.

On the other hand, replacing your entire roof provides an opportunity for a fresh start and minimizes future maintenance concerns. By investing in a new roof, you can ensure that all potential issues are addressed, such as weak spots or deteriorating materials, which might require frequent repairs if left unattended.

When contemplating future maintenance needs, keep in mind that preventing small problems from escalating into major ones can save you significant time and money in the long run.

It’s crucial to consult with a trusted roofing contractor who can conduct a thorough inspection and advise on whether repairing or replacing your roof would be more beneficial based on its current condition and projected lifespan.

Benefits of Repairing Your Roof

Repairing your roof is a cost-effective option that can extend the lifespan of your roof, saving you money in the long run. But repairing a few shingles or patching up minor damage may not always be enough to address underlying issues. A roof repaired is not equivalent to a new roofing system, with brand new shingles and materials.

Cost-Effective Option

Repairing your roof can be a cost-effective option when compared to the hefty price tag of a total roof replacement. The cost of repairs is usually less expensive per square foot than replacing the entire roof.

Additionally, bulk discounts on materials are not available for repairs, which means that you won’t benefit from any savings in that regard.

While the initial cost may be lower, repairing your roof also comes with some long-term considerations. For example, if your existing roof is older or has experienced significant damage, opting for repairs might not extend its lifespan by much.

Ultimately, deciding whether to repair or replace your roof depends on several factors like the extent of damage and age of your current roofing system. It’s always a good idea to consult with trusted roofing contractors who can conduct a thorough inspection and provide expert advice tailored to your specific situation.

Extends Lifespan of Your Roof

Repairing your roof can be a cost-effective option that not only fixes existing roof damage but also extends the overall lifespan of your roof. By addressing minor issues promptly, such as replacing a few missing shingles or fixing a small leak, you prevent these problems from escalating into more significant and costly repairs down the line.

For example, asphalt shingle roofs typically have a lifespan of 20 to 30 years. However, without regular upkeep and necessary repairs, their longevity can be significantly reduced.

By addressing minor damages early on, you can extend the life expectancy of your asphalt roof by several years.

Remember that roof repair is an ongoing process rather than a one-time fix. Regular inspections and proactive maintenance are essential in identifying potential issues early on and preventing them from causing further damage.

Benefits of Replacing Your Roof

Replacing your roof comes with several advantages over roof repair. Firstly, a brand new roof provides improved protection for your home from roof leak and new shingles are often covered by warranty for 25-50 years. Roofing companies will often advocate for a new roof in cases of severe roof damage, because it’s more cost effective long-term to opt for a complete roof replacement at that point.

Additionally, a new roof enhances the energy efficiency of your home by providing better insulation and reducing heat loss or gain through the roof. Any professional roofing company will give you a comparison of repair vs replace roof after a proper roof inspection.

Replacing your old or damaged roof provides peace of mind. You won’t have to worry about ongoing repairs or potential problems down the line when you invest in a complete replacement.


Roof repairs are often a cost-effective option that can extend the lifespan of your roof. By addressing minor issues such as missing shingles or leaks early on, you can prevent further damage and save money short-term.

However, there are situations where replacing your entire roof may be necessary, or make the most sense long-term. If your asphalt shingle roof is approaching 15-20 years old and there are signs of significant structural damage, a complete new roof installation may be warranted.

Ultimately, making an informed decision about repairing or replacing your roof requires careful consideration of all these factors. A leaky roof often signals a problem that requires more than replacing a few shingles.

Tresnak Roofing can help you assess both short-term costs and long-term benefits when considering repairing or replacing your roofing system. Regular maintenance and timely repairs can prolong the life expectancy of most roofs while saving money, however a new roof adds a lot of value and longevity to your home.
