By understanding both the pros and cons of a metal roof, you can make an informed decision for your property.
What Are the Biggest Disadvantages of a Metal Roof?
The disadvantages of metal roofing depend on the type of metal roof being installed.
Common considerations include:
Higher upfront cost
Specialized installation
Thermal expansion and contraction
Possible denting
Oil canning
Snow and ice sliding
Repair complexity
Panel color matching
Walking difficulty
Potential corrosion when materials or coatings are damaged or incompatible
These disadvantages do not mean metal roofing is a bad product. They simply need to be compared with the advantages before deciding which roofing system makes sense for the home.
1. Metal Roofing Usually Costs More Upfront
One of the biggest disadvantages of metal roofing is the initial investment.
A quality standing-seam metal roofing system can cost considerably more upfront than a standard architectural asphalt shingle roof.
The final cost depends on:
Metal type
Panel profile
Gauge or thickness
Paint finish
Roof pitch
Roof complexity
Tear-off
Decking
Flashing
Trim
Valleys
Chimneys
Labor
Homeowners should compare complete installed roofing systems rather than material prices alone.
2. Metal Roofing Requires Specialized Installation
Metal roofing installation is different from asphalt shingle installation.
Standing-seam systems may require specialized equipment, panel fabrication, clips, seams, flashing details, and knowledge of thermal movement.
Poor installation can cause problems involving:
Leaks
Fasteners
Panel movement
Flashing
Oil canning
Wind performance
Water drainage
Because metal roofing can represent a larger investment, installer experience becomes particularly important.
3. Metal Roofs Expand and Contract
Metal naturally expands when heated and contracts when temperatures fall.
A properly designed metal roofing system accounts for this movement.
If panels are incorrectly fastened or restrained, thermal movement can contribute to stress, distortion, attachment problems, or leaks.
The Metal Construction Association specifically notes that metal-panel systems must account for substantial thermal movement and that incorrect design can contribute to attachment fatigue or failure.
This is especially relevant in Northeast Ohio because roofing materials experience major temperature swings between summer and winter.
4. Metal Roofs Can Show Oil Canning
Oil canning is visible waviness that may appear across the flat areas of metal roofing panels.
It is primarily an aesthetic issue rather than automatically indicating structural failure.
Oil canning can be influenced by:
Panel width
Metal thickness
Manufacturing
Handling
Installation
Thermal movement
Roof decking
Lighting and viewing angle
The Metal Construction Association notes that oil canning can occur in steel, aluminum, zinc, or copper panels and cannot always be completely eliminated.
Homeowners choosing wide flat standing-seam panels should understand this appearance before installation.
5. Metal Roofing Can Dent
Metal roofing can be dented by large hail, falling tree limbs, tools, or people walking improperly on the roof.
The likelihood of denting depends on:
Metal type
Panel profile
Material thickness
Support underneath
Hail size
Impact energy
Roof slope
A dent may sometimes be cosmetic while other impacts can damage the coating or roofing system.
Do not say every metal roof is more hail-resistant than every asphalt shingle.
Performance varies by actual product.
6. Snow and Ice Can Slide Off Metal Roofs
Smooth metal roof surfaces can allow accumulated snow and ice to release suddenly.
On a Northeast Ohio home, sliding snow can create hazards around:
Entryways
Driveways
Walkways
Vehicles
Decks
Landscaping
Lower roofs
Gutters
The Metal Construction Association specifically warns that steep, slippery roof surfaces can allow large amounts of snow and ice to release suddenly and recommends properly engineered snow-retention systems where appropriate.
Do Metal Roofs Need Snow Guards in Northeast Ohio?
Some metal roofs may benefit from engineered snow-retention systems.
Snow guards are designed to help hold snow on the roof and allow it to melt or release more gradually instead of sliding off in a large mass.
Whether they are needed depends on:
Roof pitch
Roof geometry
Panel type
Snow load
Entrances
Walkways
Parking areas
Lower roofs
Local conditions
Snow-retention systems should be designed for the specific roof rather than randomly attaching small guards to panels.
The MCA specifically notes that snow-retention design should account for roof-specific forces.
7. Metal Roof Repairs Can Be More Complicated
Repairing metal roofing can require specialized materials and installation knowledge.
Problems may involve:
Seams
Clips
Fasteners
Panel ends
Flashing
Penetrations
Sealants
Coatings
Panel replacement
Removing one damaged metal panel may be more complicated than replacing several asphalt shingles.
The repair method depends heavily on the particular metal roofing system.
8. Matching Old Metal Panels Can Be Difficult
Metal roofing colors and finishes can change over many years of weather exposure.
If one panel becomes damaged years after installation, obtaining an exact replacement may be difficult if:
The manufacturer discontinued the color
The panel profile changed
The coating changed
The existing panels faded
The metal thickness is no longer available
The original installer or supplier is gone
A technically compatible replacement panel may therefore still look different from the surrounding roof.
9. Walking on a Metal Roof Can Be Difficult
Metal roofs can become extremely slippery when wet, frosted, snowy, or covered with debris.
Walking incorrectly can also damage certain panels or finishes.
Homeowners should avoid walking on a metal roof themselves.
Inspections and repairs should be handled by professionals familiar with the specific roofing system and appropriate fall-protection requirements.
10. Condensation Can Become a Problem if the Roof Assembly Is Poorly Designed
Metal roofing does not automatically cause condensation.
However, a poorly designed roof assembly can experience moisture problems when warm, humid indoor air reaches cold roofing surfaces.
Proper:
Ventilation
Insulation
Air sealing
Vapor control where appropriate
Underlayment
Roof design
all matter.
Condensation should be evaluated as part of the complete building assembly rather than blamed solely on the metal roofing material.
The Metal Construction Association notes condensation as an important design consideration for metal-roof retrofit projects.
11. Corrosion Can Occur Under Certain Conditions
Modern coated metal roofs are designed to resist corrosion, but corrosion can still occur when the roofing system is exposed to unfavorable conditions.
Potential causes include:
Damaged protective coatings
Incompatible metals
Improper fasteners
Standing water
Trapped debris
Chemical contamination
Improper rooftop equipment drainage
Poor detailing
Do not describe Cleveland as having marine saltwater exposure.
Lake Erie is freshwater.
The concern for Northeast Ohio should instead focus on choosing compatible roofing components and maintaining the protective coating system.
Are Metal Roofs Really Loud When It Rains?
Not necessarily.
A residential metal roof installed over solid roof decking with an attic, insulation, and finished ceiling may not be dramatically louder than other roofing systems.
Noise can be more noticeable in structures where metal panels are installed over open framing or where there is little insulation.
The Metal Construction Association specifically describes the blanket claim that metal roofing is inherently loud during rain as a myth.
Are Metal Roofs Heavier Than Asphalt Shingles?
Metal roofing is generally lighter than asphalt shingles.
The Metal Construction Association reports common metal roofing around 0.7–1.3 pounds per square foot compared with approximately 2–4 pounds per square foot for asphalt shingles.
A structural evaluation can still be required depending on the particular building and roofing project, but metal roofing should not be described as an unusually heavy roofing material.
Do Metal Roofs Need to Be Recoated Every 5 to 10 Years?
Maintenance requirements depend on the particular metal, coating system, manufacturer, installation, and environment.
A properly finished residential metal roof should not automatically be expected to need full recoating every five to ten years.
Homeowners should follow the maintenance recommendations for the specific roofing product installed.
Metal Roof vs Asphalt Shingles: Which Costs Less?
Architectural asphalt shingles generally have a lower upfront replacement cost than premium standing-seam metal roofing.
Metal roofing may appeal to homeowners who prioritize:
Long-term durability
Distinctive appearance
Metal construction
Low weight
Potentially longer service life
Architectural asphalt shingles may appeal to homeowners who prioritize:
Lower upfront cost
Broad color and style availability
Simpler repairs
Easier material matching
Familiar residential appearance
Neither material is automatically best for every Northeast Ohio home.
When Do Asphalt Shingles Make More Sense Than Metal?
Asphalt shingles may make more sense when the homeowner wants:
A lower upfront roof replacement price
A traditional residential appearance
More color choices within a specific budget
Simpler localized repairs
Widely available replacement materials
A faster or more familiar installation system
The correct roofing material depends on the house, budget, roof design, and homeowner’s long-term plans.
When Does Metal Roofing Make More Sense?
Metal roofing may make more sense for homeowners who:
Plan to remain in the property long term
Prefer the appearance of standing seam
Are comfortable with the higher upfront cost
Want a lightweight roofing system
Want a premium exterior appearance
Understand potential snow-retention requirements
Are hiring a contractor experienced with metal roofing
Northeast Ohio Weather and Metal Roofing
Metal roofing can perform well in Northeast Ohio, but the system must be designed for the local environment.
Homes throughout Northeast Ohio experience:
Lake-effect snow
Ice
High winds
Heavy rain
Summer heat
Freezing temperatures
Repeated freeze-thaw cycles
Major seasonal temperature changes
These conditions make thermal movement, snow retention, flashing, drainage, ventilation, roof penetrations, and proper installation especially important.

1. Initial Cost
One of the most significant disadvantages of metal roofing is its higher upfront cost compared to traditional roofing materials like asphalt shingles. While the cost of a metal roof can vary depending on the material (such as steel, aluminum, or copper) and the type of roof system (standing seam, corrugated, or metal shingles), it’s generally more expensive than other options.
A. Higher Material Costs
Metal roofing materials tend to be more expensive per square foot than asphalt shingles or wood shakes. High-end metals like copper or zinc will be at the top of the price range, while more common metals like steel and aluminum may cost less.
B. Additional Labor Costs
Since metal roofing installation requires specialized skills and equipment, it often takes longer to install than other roofing materials. This can increase labor costs, especially if you need to hire a professional with experience in metal roof installation. A roofing company in Cleveland or Lakewood may charge higher rates for metal roof installation due to the complexity of the work involved.
C. Long-Term Savings
Although the initial cost is higher, many homeowners find that the long-term savings in energy efficiency, durability, and maintenance make metal roofs a worthwhile investment. In some cases, a metal roof can last two to three times longer than an asphalt roof, which may offset the higher initial costs.
2. Noise
While metal roofs are known for their strength and durability, they can be much noisier than traditional roofing materials, especially during heavy rain or hailstorms. This is particularly true if the roof is installed directly over plywood decking without any insulation in between.
A. Rain and Hail Noise
When rain or hail hits a metal roof, the noise can be significantly louder than on other roof types. This can be particularly bothersome if your metal roof is installed on a structure with a vaulted ceiling, which may amplify the sound.
B. Sound Insulation
To mitigate this noise, homeowners may need to invest in additional soundproofing measures. This might involve installing extra insulation beneath the metal roof or choosing specific roofing products that are designed to minimize noise. While this may add to the overall cost of the installation, it can make living under a metal roof much more comfortable.
3. Denting and Scratching
Despite their toughness, metal roofs are still susceptible to denting and scratching under certain conditions, particularly if they are made from softer metals like aluminum.
A. Hail Damage
While metal roofs are more resistant to hail than asphalt shingles, large hailstones can still cause dents, particularly if the roof is not properly installed or if the metal is of a thinner gauge. If you live in an area prone to severe storms, such as Cleveland, this could be a concern when considering a metal roof.
B. Physical Damage
Metal roofs can also become scratched or scuffed during installation or if something comes in contact with them while performing maintenance tasks. Although most metal roofs are coated with protective finishes to help prevent rust, scratches or dents can lead to corrosion over time if the coating is damaged.
4. Expansion and Contraction
Another disadvantage of metal roofing is that it is prone to expansion and contraction due to temperature fluctuations. Metal expands when heated and contracts when cooled, and this can create potential issues over time.
A. Warping
If not properly installed, the movement of metal panels can lead to warping, buckling, or even the loosening of fasteners. The metal’s natural expansion and contraction can cause panels to shift or make noise as they move. This is especially true for large, flat metal panels.
B. Installation Techniques
To minimize the impact of expansion and contraction, it’s crucial to hire an experienced roofer who knows how to install metal roofing properly. Special fasteners and techniques, such as leaving room for the panels to move, can help alleviate these issues. In areas like Medina and Beachwood, where temperature fluctuations are common, this is a particularly important consideration.
5. Limited Design Options
While metal roofing comes in a variety of styles, colors, and finishes, it may have fewer design options compared to traditional roofing materials like asphalt shingles or tile. Metal roofing typically has a more industrial or contemporary look, which may not appeal to everyone.
A. Aesthetic Limitations
While some metal roofing options mimic the look of other materials like slate or wood, they can still look starkly different from traditional roof materials. If you’re looking for a more classic or rustic look, you may find that metal roofing doesn’t align with your desired aesthetic. Homes with historical or vintage designs, particularly in older neighborhoods like Cleveland Heights, may not be suitable for metal roofing.
B. Increased Complexity for Customization
If you want a more customized look for your roof, adding features like decorative elements or intricate roofing designs can be more challenging with metal. Custom designs might require special manufacturing or additional materials, which can increase both the cost and installation time.
6. Installation Challenges
Installing a metal roof is a more complex process than installing traditional roofing materials, and it requires specialized skills and tools. For this reason, installation can take longer and be more expensive.
A. Experienced Roofers Required
Metal roofing needs to be installed by roofers who are specifically trained in working with this material. An inexperienced roofer may make mistakes during installation, which could lead to water leaks, improper ventilation, or other issues. The complexity of installation also means that the project timeline may be longer compared to other roofing types.
B. Roof Reinforcement
In some cases, especially when installing a metal roof over an existing roof (called a re-roof), the underlying structure may need to be reinforced to accommodate the weight and design of the new roof. This can add additional costs and time to the project.
7. Specialized Maintenance
Although metal roofs are generally low-maintenance compared to other roofing materials, they do require some specialized maintenance to keep them in top condition.
A. Rust Prevention
One of the main concerns with metal roofs is rust. If the protective coatings on the metal roof are scratched or damaged, moisture can penetrate the surface and cause rust to form. Regular inspections are necessary to ensure that the roof is intact and free from rust.
B. Cleaning
Metal roofs can collect debris like leaves, branches, and dirt, especially in areas with heavy tree cover. These materials can trap moisture against the roof, which could lead to corrosion or mold growth if not cleaned regularly. While cleaning a metal roof is not particularly difficult, it does require special tools or professional help to avoid causing damage.
C. Sealing and Coating
Periodically, the roof may need to be resealed or recoated to maintain its protective finish and prevent corrosion. This is an added step that homeowners may need to plan for every 5 to 10 years.
8. Corrosion Concerns
While metal roofs are designed to resist rust and corrosion, certain environmental factors can still lead to corrosion issues over time.
A. Saltwater Exposure
In coastal areas where the air is salty, such as Cleveland along the lakefront, metal roofs can be more vulnerable to corrosion due to the presence of salt in the air. Saltwater accelerates the process of rust formation, which can significantly reduce the lifespan of a metal roof.
B. Improper Coating
Another potential issue is the quality of the coating on the metal roof. Lower-quality coatings may degrade more quickly, leaving the metal exposed to the elements and susceptible to rust. It’s essential to choose a roofing system with a high-quality finish to prevent these issues.
Conclusion
Metal roofs are a popular choice for many homeowners due to their durability, energy efficiency, and long lifespan. However, as with any roofing material, metal roofs come with a range of potential disadvantages that need to be carefully considered before making a decision. Some of the disadvantages include:
- Higher initial cost compared to other materials
- Noise issues during rain and hail
- Denting and scratching concerns
- Expansion and contraction that can cause problems
- Limited design options for certain aesthetic preferences
- Installation complexity and need for experienced professionals
- Specialized maintenance requirements
- Corrosion concerns in certain environments
Ultimately, deciding whether a metal roof is right for your home or business depends on a variety of factors, including your budget, climate, aesthetic preferences, and long-term goals.
