Properly sealing seams and guaranteeing watertightness is vital in preventing common roof leakage. As you inspect your metal roof, you might come across common problem areas where leaks tend to occur, such as around screws, lap joints, and flashing details. These regions are especially susceptible to water infiltration due to the tendency of metal to expand and contract over time.
To address these common leakage issues effectively, it is important to identify the root cause of the problem before applying a coating. For example, if you notice corrosion or rust near the screws or lap joints, proper surface preparation, including power washing, cleaning, and priming, becomes essential to guarantee strong adhesion of the coating material to the metal surface.
Using a high-performance coating like ArmorGarage's industrial-grade metal roof coating can provide long-term protection by encapsulating the surface fully and sealing any gaps that might lead to water penetration. Regularly inspecting and maintaining the coating, particularly at the vital points mentioned above, will help extend the life of your metal roof and reduce future repair costs.
Improper Installation Issues

Improper Installation Issues
The problems you encounter with your metal roof often arise from the quality of its installation, where misplaced screws, inadequate sealing, or skipped maintenance progressively corrode the structure. It's not rare to see metal roofs leaking due to these issues. Even with the best materials, improper installation can render your roof vulnerable to water intrusion.
Here are key improper installation issues you should know:
- Fastener Errors: Overdriven, underdriven, or incorrectly angled screws can create openings for water to seep in.
- Sealant Omissions: Inadequate or missing sealants around joints and flashings can allow moisture to collect and cause damage.
- Flashing Issues: Poorly installed or damaged flashing points, such as chimneys and valleys, create a direct path for water to enter your roof.
Metal Substrate Preparation
Improper surface preparation is often the root cause of metal roof coating failure, as inadequate cleaning, degreasing, and priming deprive the coating of a strong foundation. Imagine if you were to apply a new coat of paint to a dirty, oily wall. The results would be predictable—the paint would peal, blister, and fail to provide the necessary protection. The same principle applies to metal roofs. Without proper surface preparation, the new coating cannot adhere reliably, allowing moisture and weather conditions to attack the metal substrate itself.
This failure to prepare the metal substrate leads to:
- Insufficient bonding between the coating and the substrate, making it vulnerable to peeling and blistering.
- Creation of a pathway for water and other corrosive substances to seep beneath the coating and cause damage.
To avoid these pitfalls and guarantee a successful recoating project, focus on creating a clean, durable surface for the new coating to adhere to. By diligently addressing any existing issues with the substrate, you set the stage for a strong, long-lasting bond that will protect your metal roof for years to come.
Sealant and Coating Application

Now that you've confirmed a clean and durable metal substrate, you'll need to apply the sealant and coating to guarantee peak performance and longevity. This is a critical step, as the sealant and coating will help protect your metal roof from corrosion, moisture intrusion, and other environmental factors. Here are some key considerations to remember:
- Proper Adhesion: Verify the coating is compatible with the metal substrate and has ideal adhesion properties.
- Correct Application: Follow the manufacturer's instructions for application, paying attention to details such as thickness and drying time.
- Quality Finish: Ensure a smooth, even finish with no streaks or bubbles to confirm the coat performs as intended.
