DIY vs. Professional Roof Repair: When to Call the Experts

Last Updated on February 12, 2025 by Tanya Janse van Rensburg

As a homeowner, taking care of your home often means tackling repairs yourself. 

Whether that means learning how to spot and fix common roofing issues, identifying when an HVAC system is faulty, or just determining something as simple as if there’s an insulation issue.

Knowing when to contact a professional is equally important. 

While there may be a certain satisfaction that comes from fixing things yourself and cost savings, making a mistake can lead to more expensive issues down the line.

When it comes to something as important as issues with your roof, an expert who has specialized knowledge, tools, and professional expertise is always best. 

Attempting to fix a repair by yourself can lead to serious mistakes, safety hazards, and even voided warranties on your home. 

Learn the most common roofing problems along with what you can fix on your own in addition to when you should call the pros.

The Most Common Roofing Problems

Before deciding whether or not you should take on a repair job by yourself, you must understand the most common issues you may run into. 

These problems can range from minor wear and tear issues to major structural concerns. 

The most prominent include:

  • Missing or damaged shingles: Often caused by wind, storms, or aging, missing shingles can quickly lead to leaks if not replaced

  • Leaks and water damage: Small leaks might seem manageable at first, but they can quickly worsen and lead to mold, rotting wood, and ceiling stains

  • Clogged or damaged gutters: Blocked gutters prevent proper drainage, leading to water backup and potential roof damage over time

  • Flashing issues: Flashing is the material that seals roof joints and it can loosen over time, causing water seepage near chimneys, vents, or skylights

  • Structural concerns: A sagging roof or rotting wood is a serious issue that requires immediate professional attention due to the immediate threat it poses

    While some of the above problems have simple solutions, others demand expert repair. 

    Knowing which is which can save you time and money in the long run while also ensuring your safety. 

    DIY Roof Repairs: What a Homeowner Can Handle

    Assuming you have a basic comfort with tools and a sturdy ladder, there are a few roofing tasks you can handle safely on your own. 

    The first is gutter cleaning and downspouts. 

    Gutters play a major role in moving water away from your home, but when they get clogged with leaves and debris they can cause leaks and foundation damage to your roof. 

    Regular cleaning before winter and after storms will help to prevent further issues.

    If you notice a few shingles missing or curling, consider replacing them a relatively simple job. 

    You’ll need to purchase matching replacement shingles, nails, and other items to remove and replace the damaged ones. 

    Be sure to remove the old ones properly with a pry bar and secure the new ones effectively to prevent future leaks.

    Building off of this, if you happen to notice any minor leaks or small gaps around the vents in your roof you can seal these with a high-quality sealant to provide a temporary fix. 

    Be aware that this is a good short-term solution, but it shouldn’t replace professional repairs for larger leaks in the future. 

    Some general safety precautions to keep in mind if you plan on getting up to your roof with a ladder include:

    1. Use a sturdy and well-anchored ladder

    2. Wear non-slip shoes for better grip

    3. Always work in dry weather

    4. Ensure someone is home in case of emergencies

    DIY tasks can extend the life of your roof, but there are many situations where admitting you are out of your depth can help keep you safe.

    The Risks of DIY Roof Repairs 

    Attempting any major roofing work without the right expertise, tools, or skills can be both dangerous and costly. 

    Falls from roofs account for a significant number of home improvement injuries per year, with 70% of fall-related work deaths being attributed to this cause. 

    Without the right safety equipment, working on a steep roof can be very risky. 

    Beyond safety, there are structural integrity concerns to keep in mind. 

    Fixing a few shingles might seem easy at first, but if they are installed incorrectly, for example, you could create new leaks or compromise the integrity of your whole roof.

    When to Call a Professional Roof Repairman

    Naturally, certain roofing problems are too complex or dangerous to be handled as a DIY repair. 

    Below are some of the most common situations in which hiring a professional is the best choice:

    • Major Leaks or Widespread Water Damage: If water stains appear on your ceilings, walls, or attic, it’s a sign that there may be a major leak somewhere. Since water damage often extends beyond what’s visible, it’s always best to get a professional to take a look at things. 

    • Structural Issues: A sagging roof, rotting framework, or large sections of missing shingles can all indicate serious structural concerns that require an expert roofer to evaluate and fix. 

    • Flashing or Chimney Repairs: Flashing is crucial for keeping water out of vulnerable areas of your home and if it’s loose or rusting then a professional may be needed to seal it to prevent future leaks. 

    • Large-scale Shingle Replacement: Replacing a few shingles is manageable on your own, but if a significant portion has been damaged then it’s likely time for a professional reroofing job.

    • Post-storm Repairs and Inspections: Storm damage isn’t always obvious to the eye but a professional roofer should be called to conduct a thorough inspection to look for hidden issues and to document damage for insurance claims if you believe something is amiss.

    Conclusion: Make The Right Repair Choice For Your Home

    When it comes to roofing, knowing your limits is everything. 

    Cleaning gutters, replacing a few shingles, and sealing small cracks are all acceptable DIY tasks that aren’t likely to have major consequences.

    Always ensure to call a repairman if there are complex issues like those described above which may lead to injuries, void warranties, or cause long-term damage. 

    If you are ever in doubt, just call a pro to err on the side of caution.
