Metal roofing is a popular choice for homeowners and business owners alike, thanks to its durability, energy efficiency, and low maintenance needs. However, as with any roofing system, it is not without its challenges. While metal roofs are generally built to last, certain issues may arise over time that need attention. This blog will address some of the most common metal roofing problems, how to solve them, and the importance of choosing a reliable service provider like Nurnberg Roofing to keep your metal roof in top shape.
1. Corrosion: A Major Threat to Metal Roofs
What is Corrosion?
Corrosion is the gradual deterioration of metal due to chemical reactions between the metal and moisture or other environmental factors. This is particularly an issue for roofs in coastal areas, where salty air can accelerate the corrosion process. Over time, corrosion can compromise the structural integrity of your metal roof and cause leaks.
How to Solve It?
To prevent corrosion, make sure your metal roof is coated with a high-quality protective layer, such as zinc or aluminum-based coatings. These coatings help prevent moisture from directly coming into contact with the metal surface. Regular maintenance, including inspections for rust spots, will allow you to catch any potential issues before they become serious.
If you notice signs of corrosion, address them promptly by cleaning the affected areas with a wire brush and a solution of water and vinegar. For more severe corrosion, you might need to replace rusted panels or hire a professional service like Nurnberg Roofing to handle more extensive repairs.
2. Leaking Roofs: Common But Solvable
Why Do Metal Roofs Leak?
Although metal roofing is known for its water resistance, leaks can still occur due to various reasons, such as improper installation, poor sealing around fasteners, or damaged flashing. Leaking roofs are especially concerning in the case of older metal roofs or when the installation wasn’t done properly from the start.
How to Solve It?
Inspect your metal roof at least twice a year to ensure the fasteners are secure, seals around joints are intact, and flashing is in good condition. If your roof has developed a leak, pinpointing the source is the first step. It may be due to loose fasteners, where the roofing panels have shifted, or it could be damaged flashing. You can use roofing sealants or silicone caulking around the leaking area to fix small leaks.
For significant leaks or installations that are more complex, contact a professional roofing company like Nurnberg Roofing. With their experienced team, you can ensure the roof is fixed properly and does not suffer from additional leaks in the future.
3. Poor Installation Leading to Other Issues
The Importance of Proper Installation
Even the best quality metal roofing can fail if it’s not installed correctly. Poor installation can cause all sorts of problems, including misaligned panels, rust spots, and improper flashing. Misalignment is often due to unlevelled or incorrectly spaced supports. These factors can affect the overall performance and longevity of your roof, leaving it vulnerable to issues like leaks, corrosion, and wind damage.
How to Solve It?
The best solution is to hire a professional roofing contractor like Nurnberg Roofing who knows exactly how to install a metal roof the right way. During installation, ensure the roofing panels are aligned properly, the fasteners are correctly placed, and all edges and flashing are sealed tight.
In case of poorly installed roofs, you might need to replace the problematic panels or adjust the roofing structure. The cost of fixing this may be high, but it’s better than dealing with worsening issues down the line.
4. Expansion and Contraction: Movement of the Metal
Why Does the Metal Roof Expand and Contract?
Metal expands and contracts due to temperature changes. This is particularly common during seasonal transitions, where the difference between summer heat and winter chill creates movement in the material. Over time, the constant expansion and contraction can lead to loose fasteners, misalignment, or damage to the roof’s seams.
How to Solve It?
Most metal roofing systems are designed to accommodate expansion and contraction. However, if the roof has expanded or contracted too much, it could indicate that the fasteners were not installed with enough flexibility. Tighten any loose fasteners or replace any damaged panels.
Using metal panels with expanded spacing and adjustable clips can also help minimize the impact of this natural movement. Regular inspections by a roofing contractor, like Nurnberg Roofing, are key in keeping this issue under control.
5. Noise: Noisy Metal Roofs During Rain or Hail
Is Metal Roofing Noisy?
One concern with metal roofs is the noise that can occur during heavy rain or hailstorms. Metal roofing tends to amplify sound, so during these storms, the noise can be uncomfortable. Some homeowners feel the noise is a drawback compared to other roofing materials that tend to absorb sound better.
How to Solve It?
To mitigate noise, you can install a solid sheathing underneath your metal panels. Materials like plywood or foam board insulation can create a barrier between the roof and the interior, reducing sound transfer. This approach provides both soundproofing and added insulation.
Alternatively, thicker metal roofing panels may reduce sound, but this can add to the material cost. If this is an issue for your home, reach out to Nurnberg Roofing to explore options tailored to your needs.
6. Punctures and Dents: Impact Damage
What Causes Metal Roofs to Get Punctures or Dents?
While metal roofs are durable, they aren’t entirely immune to impact damage. Severe weather, such as hailstorms, physical impacts from tree branches, fallen debris, or even human activity (like walking on the roof), can cause punctures or dents to your metal roof.
How to Solve It?
Minor dents usually do not affect the performance of the roof but can be unsightly. If the damage is limited, you can attempt to smooth out the dents using a hammer and a block of wood to protect the metal. Be careful not to cause additional damage.
However, deeper punctures and larger areas of damage require more attention. A professional inspection from Nurnberg Roofing will help identify whether the affected section of the roof needs to be patched or replaced entirely.
7. Fading and Discoloration: Losing the Shine
Why Does Metal Roofing Fade?
Exposure to the sun’s UV rays, rain, and other weather elements will, over time, cause the color of your metal roof to fade. Some materials, like those with painted or coated finishes, tend to lose their brightness after years of exposure. Although fading doesn’t directly impact the roof’s performance, it can detract from the curb appeal of your property.
How to Solve It?
Regular cleaning can help prevent surface buildup and UV damage. Clean your metal roof with a mild detergent and rinse it thoroughly to prevent streaks or discoloration. Repainting or re-coating your metal roof with a fresh finish every few years will also maintain its appearance.
When repainting a metal roof, be sure to select the right product for your specific roofing material. If you’re unsure of the best approach for your roof, Nurnberg Roofing can help you choose the right coating and apply it correctly.
8. Wind Damage: Impact of Strong Winds
What Causes Wind Damage?
While metal roofs are designed to withstand high winds, they are not immune to damage from particularly strong gusts. If metal panels are not properly secured, they can be lifted or torn off. In severe cases, the entire roof can suffer significant damage from windstorms.
How to Solve It?
The most effective solution to prevent wind damage is ensuring your metal roof is properly installed with all panels securely fastened. Metal roofs with standing seam systems are excellent at resisting wind uplift, and you can increase wind resistance by using appropriate fasteners.
If your roof does sustain wind damage, get in touch with Nurnberg Roofing right away for professional repair.
FAQs: Solving Metal Roofing Problems
Q1: Can I fix metal roofing corrosion myself?
Yes, small patches of corrosion can often be treated by cleaning the rust off and applying a rust inhibitor or sealant. However, if the corrosion is extensive, it’s best to have a professional roof technician assess and replace the affected areas to prevent further damage.
Q2: How often should I check my metal roof for problems?
It’s advisable to inspect your metal roof at least twice a year—once in the spring and once in the fall. Regular inspections will allow you to catch any minor issues early, preventing costly repairs down the line.
Q3: Is it possible to add insulation to reduce noise from my metal roof?
Yes, it’s possible to add a layer of insulation or sheathing underneath the metal roof to minimize the noise from rain and hail. Insulation acts as a sound barrier and helps maintain comfortable indoor temperatures as well.
Conclusion
While metal roofing is a strong, reliable roofing option, it does have some common issues that homeowners should be aware of. Whether it’s dealing with corrosion, addressing leaks, fixing poor installation, or handling impact damage, taking proactive steps to care for your metal roof is essential for its longevity. Working with a trusted roofing company like Nurnberg Roofing ensures that any issues are handled professionally, maintaining the performance and beauty of your metal roof for years to come.
