When it comes to replacing your roof, it’s easy to see why you might consider doing it yourself. After all, replacing your roof can be one of the more expensive home improvement projects, and cutting out labor costs could save thousands. But before you grab your ladder, utility knife, & tin snips and start tearing off old shingles, it’s crucial to understand what you’re getting into. A DIY roof replacement is a big undertaking—one that comes with both potential rewards and serious risks.
At Black Hill Roofing in Austin, we’ve seen homeowners successfully take on their own roof repair or replacement, but we’ve also seen many more struggle or run into problems they hadn’t anticipated. In this blog post, we’ll walk you through the pros and cons of replacing your own new roof, helping you decide if this is the right move for you or if hiring a professional roofing contractor is a better option.

Pros of DIY Roof Replacement
- Cost Savings
The main draw of a DIY roof replacement is the potential to save money. By removing labor costs, you’re only paying for materials like asphalt shingles and tools, which can seem like a substantial saving. But it’s important to consider that roofing materials are still a significant expense, and the amount you save may not be as much as you’d expect once the total cost is factored in. - Learning a New Skill
If you enjoy hands-on work and tackling home projects, replacing your roof could be an opportunity to learn a valuable skill. You’ll gett more experience handling tools like a caulk gun and an air compressor to ensure materials are sealed properly. Not only will you better understand the structure of your home, but the sense of accomplishment that comes from completing such a massive project can be incredibly rewarding. - Full Control of the Project
When you’re managing the roof installation, you get to make every decision—what materials to use, whether to go with asphalt shingles or a metal roof, how quickly or slowly the project goes, and what level of detail you want to focus on. Having that much control can be empowering, especially if you’re very particular about your home.
The Cons of DIY Roof Replacement
- Serious Safety Concerns
Roofing is dangerous work. It involves climbing ladders, working at steep angles, and handling heavy materials—all while being high off the ground. Many DIYers don’t have the proper safety equipment, such as harnesses or proper footwear, that professionals use. Falls from roofs are one of the most common causes of serious injuries for homeowners, so it’s vital to consider whether you’re comfortable with the physical risks involved. - Work Time Commitment
While you might think you can knock out a roof installation over a couple of weekends, the reality is often very different. Even experienced DIYers find that reroofing a house takes far longer than anticipated. Between stripping off old shingles, installing drip edge and step flashing, and dealing with any unforeseen issues (like rotting decking), this project can easily stretch out over several weeks—or even months. And any delays could leave your home vulnerable to weather damage. - Lack of Experience
Even with all the instructional videos and articles at your fingertips, nothing can replace hands-on experience. Roofing is a specialized skill, and mistakes—whether it’s improperly aligned shingles, gaps, or miscalculating your drip edge, or not securing step flashing correctly—can lead to roof leaks, rot, and other structural problems. These issues may not be immediately noticeable but can cause significant damage down the road. - Voiding Warranties
Many roofing materials come with warranties, but these are often only valid when installed by a licensed professional. If you opt to install the roof yourself, you could void those warranties, leaving you unprotected if the materials fail or if issues arise in the future. This is an important consideration, as repairs or replacements under warranty can save you significant costs down the line. - Hidden Costs
DIY projects rarely stay within budget. You may have to rent or buy special tools, replace materials if mistakes are made, or address unforeseen issues like damaged decking or rotting wood. These unexpected expenses can add up quickly, potentially costing you more than you initially saved.

Common Mistakes to Avoid in DIY Roof Replacement
Even with the best intentions, many DIY roofers make mistakes that can lead to bigger issues down the road. Here are some common errors we’ve seen homeowners make—and how to avoid them.
- Incorrect Material Choice
Not all roofing materials are the same, and choosing the wrong type can affect the longevity of your roof—especially in Austin’s unique climate. Some materials may need to withstand the intense Texas heat, humidity, and occasional severe storms, while also being suitable for your roof’s slope. For instance, using asphalt shingles designed for low-slope roofs on a steeper roof can lead to premature wear and tear. It’s essential to research or consult with a professional to ensure you’re selecting the best materials for your Austin home’s specific needs. - Improper Installation of Flashing
Flashing—those metal pieces installed around chimneys, skylights, and vents to prevent water from seeping in—is crucial. DIYers often either skip this step or install step flashing incorrectly, which can lead to water infiltration and long-term damage. Ensuring your flashing is installed properly is key to prevent leaks in the long term. - Poor Ventilation
A roof needs proper ventilation to prevent moisture buildup in your attic, which can lead to mold, rot, and increased energy costs. DIYers may overlook or inadequately install ventilation systems, which is a common cause of roof damage over time. Be sure to account for ventilation in your roofing plan. - Neglecting Underlayment
Underlayment is a waterproof barrier that sits between your roofing materials and the roof deck. Skipping or incorrectly installing this crucial layer can result in water damage beneath your shingles. Make sure your underlayment is laid properly to avoid future issues. - Misjudging Weather Conditions
Roofing should only be done in dry, clear weather. A sudden rainstorm or even high humidity can cause materials to swell or not adhere properly, leading to future damage that could require additional roof repairs. Always check the forecast and plan your project around a long stretch of good weather. - Underestimating the Physical Demand
Roofing is physically demanding work. From carrying heavy bundles of shingles to maintaining balance on a sloped surface, many DIYers underestimate how exhausting the new roof process can be. Pace yourself, take breaks, and make sure you have the stamina to safely complete the job.
Is DIY Roof Replacement Right for You?
The decision to reroof your house ultimately comes down to your skills, available time, and comfort level with the risks involved. If you’re experienced with home improvement projects, have access to the necessary tools (i.e. an air compressor, roofing nails, etc), and are confident in your ability to work safely at heights, a DIY roofing might be a viable option for you.
However, if any of these factors give you pause, it’s worth reconsidering whether the cost savings are worth the potential risks. Roofing is a critical part of your home’s structure, and even a small mistake can lead to significant problems down the road. In many cases, hiring a professional roofing company can save you time, stress, and, ultimately, money.
