7 reasons to avoid DIY roof repair

Fixing your own roof may seem like a smart idea when you're staring down hefty quotes from roofing contractors — but DIY roof repair is seriously risky. From voided warranties to potential legal issues and a high risk of injury, DIY roofing may not be as clever as it seems, and roofing work is best left to the professionals.

Here, we'll talk through the seven key reasons to avoid DIY roof repair and replacement and clarify why hiring a licensed roofing contractor is probably the right move.

Why DIY roofing (usually) isn't worth the risk

1) Roofing is extremely dangerous, even for the pros

DIY roof repair carries a high risk of injury. In fact, roofing remains one of the top three most dangerous professions in the U.S., according to Roofing Contractor , the official publication of the International Roofing Expo.

Especially on steep roofs, the risk of slipping and falling is significant. To reduce your risk of injury or worse, skip the DIY and call a trusted roofer.

2) Fixing your own roof may void your warranty

If the danger alone isn't enough to stop you, know that working on your own roof will likely void your warranty. This means you won't be covered by your roof's manufacturer if your roof is damaged in a storm or other unexpected event. Victors Home Solutions lists "improper installation" as the number-one cause of a voided roofing warranty.

When roofing materials are installed by trained and certified professionals, they're automatically covered by manufacturers' warranties — many of which last anywhere from 25 to 50 years — and most roofers offer in-house labor warranties too. Opting for a DIY roof job might save you a little money in the short term, but the lack of warranty coverage could cost you big time in the future.

3) DIY roof repair increases the risk of leaks and costly issues

A roof installed by anyone other than a licensed roofing contractor is simply more likely to leak or fail. This increased risk of leaks and weak spots is yet another reason DIY roofing may not actually save you as much money as you think.

Unless you're a trained roofer, you likely don't have the skills or experience needed to effectively repair a roof. This lack of expertise significantly increases the likelihood of mistakes, which can lead to costly repairs down the line. Even if you try your best to do everything by the book, there's a certain level of know-how you just won't have on a first-time roof repair job.

4) You might have to pay more for roofing materials

DIY roof replacement may save money on labor, but retail material costs can add up.

Most professional roofing contractors can access wholesale pricing on roofing materials, allowing them to save big when purchasing bulk shingles, for example. Since you'll likely only be buying enough materials to repair or replace your own roof, you may end up spending more on materials than you otherwise would.

5) Roofing requires specialty tools and materials

Speaking of added costs, fixing your own roof means you'll need to buy or borrow specialty roofing tools like nail guns, roofing shovels and shingle cutters. IKO, a large North American manufacturer of roofing materials, lists 27 basic roofing tools needed to start safely working on roofs. But when you hire a professional roofing contractor, you won't have to foot this extra cost.

Licensed roofers also use special equipment for cleaning up job sites, like high-powered magnetic sweepers, dump trailers and netting systems. These help keep your property clean throughout the very messy process of repairing or replacing a roof, so cleanup will be much harder if you DIY.

6) DIY roof replacement could take (a lot) longer

While fixing your own roof might seem like a cost-effective solution at first, remember that time is money, and DIY roof repair can take much longer than a pro roofing job.

Most trained roofing crews can finish simple roof repairs in a few hours or less, all with your warranty and safety intact. Even a full roof replacement can be finished in one or two days, depending on the size of your roof, according to Joyland Roofing in Elizabethtown, Pennsylvania. DIY roof repairs should be expected to take much longer, since you'll be figuring out the process as you go. You'll also need to work around your schedule, which may already be limited.

7) Lack of proper insurance could lead to legal issues

Finally, working on your own roof can create serious legal issues for you and your family. If, for example, your neighbor's home or property is damaged by falling debris, you could be held liable, according to RoofCrafters , and you may not have the proper insurance to cover the damages. Roofers, on the other hand, carry special insurance that covers the company, property and crews in case problems arise.

Hobby roofers are also more likely to skip over the permitting process, which could create a host of problems if your city or county finds out. Roofing work completed without a permit in areas where permits are required could result in hefty fines or even legal penalties, according to Excel Construction Group , and you may even be required to hire a professional roofer to redo the work.

Here's why you should leave roof work to the pros

Despite the money you might save on labor, DIY roof repair just isn't worth it in most cases. Of course, you to know what's best for you and your home, but the average homeowner doesn't have the expertise, tools or time to properly install or repair a roof.

Instead, roofing work is best left to the pros, and here's why:

• Professional roofing contractors are specially trained and licensed

• Your roof will be protected by labor and materials warranties

• You won't have to buy your own tools, and you may pay less overall for materials

• Leaks, mistakes and other issues are far less likely when you hire a pro roofer

• You'll pay more upfront, but professional roofing services will save you in the long run

DIY roof repair FAQs

Do I need a permit to replace my roof myself?

In most cases, yes. If your city or county requires residential roofing permits for roof repairs or replacements, then you are required to obtain a permit prior to beginning work. Permits are required regardless of who's performing the work.

How to fix roof leaks?

The process of fixing a roof leak will depend on several factors, such as the cause of the leak and the type of roof. The best way to determine the type of repair needed is to consult with a licensed roofing contractor who can perform an inspection. Once the issue is diagnosed, hire a trusted contractor to complete the repairs rather than attempting to fix it yourself. DIY roof leak repair is generally not advised, as it may void your roof's warranty and create further issues down the line.

How much will I save if I do my own roof?

DIY roof work may save you money in the short term, but it presents a far greater risk of creating expensive problems later on.

The cost of labor generally accounts for about 60% of total roofing costs, according to industry experts like Bar Zakheim of Better Place Design & Build in San Diego , so you could save up to 60% up front by working on your own roof. But DIY roofing increases the risk of costly issues like leaks, property damage or injury. It also creates new upfront costs since you'll need to buy specialty tools and rent a truck or trailer for cleanup.
