Just like that time when I decided to trade my old car for a shiny new one, many homeowners are now asking themselves: can you put a metal roof over shingles? It’s an upgrade they’re considering but with lots of questions hanging in the balance.

You see, both cars and roofs serve crucial functions. They protect us from harsh weather conditions while offering comfort and style. But what happens when your trusted asphalt shingle roof starts showing signs of age? Do you tear it off completely or just cover it up with sleek metal panels?

long run. From hidden water damage to extra weight, these factors could turn a seemingly cost-effective solution into an expensive mistake. It may be attractive to cover aged shingles with a fresh metal roof, yet it’s critical to evaluate the potential downsides and compare them against the advantages before concluding.

Can You Put a Metal Roof Over Shingles?

If you’re wondering if a metal roof can be installed over existing shingles, it’s not an easy answer. There are some potential risks involved.

The Potential Risks of Laying Metal Over Existing Shingles

Laying a metal roof over existing shingles may seem like it saves money upfront. Putting a metal roof on top of existing shingles could result in complications later.

A crucial issue is your ability to inspect and replace bad roof decking before installing the new roofing materials. If there’s any water damage or rot in your current deck, laying metal panels directly overtop won’t fix these issues – it’ll just hide them for now.

Beyond this, extra weight from the new material can stress your home’s structure. Remember, each layer added onto your house isn’t just more protection—it also adds more pressure. Even though metal roofs aren’t particularly heavy compared with other options, they still add considerable load when installed atop old asphalt shingle roofs.

An additional concern arises if future leaks occur after installation—tracking their source becomes significantly harder due to multiple layers being present instead of just one clean sheet of roofing components above you. This makes diagnosing and fixing any possible leaks quite tricky indeed.

All things considered; while putting up new sheets without removing old ones might seem like a time and cost saver at first, it may lead to more roof problems later. Be sure to consult a reliable roofing specialist before making any choices. 

Key Takeaway: 


Switching from shingles to a metal roof? Hold up. Slapping metal over existing shingles may seem like a budget-friendly shortcut, but it hides potential issues and adds extra weight on your home’s structure. Plus, future leaks can be tougher to trace and fix. Always get expert advice before you start this type of project.

Understanding Metal Roofing and Shingle Roofing

When deciding between metal roofing and asphalt shingle roofing, homeowners must consider their respective advantages and disadvantages to make an informed decision. Both have their pros and cons that can greatly affect your home’s aesthetics, functionality, and longevity.

The Pros and Cons of Metal Roofs

Metal roofs are known for their durability. They resist harsh weather conditions like windstorms or hail better than most other materials. In areas prone to wildfires, metal roofs are especially beneficial due to their non-flammability.

But let’s not forget about energy efficiency. A well-installed metal roof reflects solar radiant heat, helping keep your house cooler during hot summer months.

Why Homeowners Choose Asphalt Shingle Roofs

A key advantage of asphalt shingle roofs lies in their cost-effectiveness – making them popular among many homeowners across Kansas City who work with Pyramid Roofing.

In terms of design flexibility too, asphalt outshines its competition offering numerous colors & styles allowing owners to match it with their property’s overall aesthetic appeal perfectly.

However, being lightweight doesn’t mean they skimp on performance; when installed properly by experienced professionals at Pyramid Roofing, these versatile shingles provide robust protection against diverse weather elements from heavy rainfalls to scorching summers.

But bear in mind that every rose has its thorn so does this inexpensive yet reliable option – requiring more maintenance compared to some alternatives due to its susceptibility towards algae growth or curling over time.

Forbes reports that while metal roofs can be expensive upfront, their durability and low maintenance needs may result in savings over time.

Key Takeaway: 


Metal roofs are durable, weather-resistant, and energy-efficient but can be expensive initially. On the other hand, asphalt shingles offer cost-effectiveness and design flexibility but may need more maintenance due to their susceptibility towards algae growth or curling. Understanding both options helps you choose a roof that suits your home’s needs best.

The Benefits of Installing a Metal Roof

When selecting a roofing system, metal roofs are becoming increasingly preferred. But why is that? Well, installing a new metal roof has several advantages over other types of roofing materials.

Durability and Longevity

Metal roofs have an impressive lifespan. With proper care, they can last 40-70 years compared to the average 12-20-year lifespan for asphalt shingle roofs. They’re also resistant to cracking or shrinking and can withstand extreme weather conditions.

Safety Features

Metal won’t spark or ignite into flames during a wildfire or lightning strike. If you live in an area where wildfires and lightning strikes are frequent, metal roofing could be your most secure choice.

Energy Efficiency

Apart from safety and durability, another significant benefit of metal roofing is its energy efficiency. It reflects solar radiant heat which helps reduce cooling costs by up to 25%.

Eco-friendly Choice

Metal roofs not only save money but also help conserve our planet. Most metal roofing materials contain recycled content ranging from 25%-95%. Moreover, at the end of their life cycle, these roofs are completely recyclable too.

Compared with asphalt shingles, despite being cost-effective initially may lead homeowners towards frequent maintenance cycles adding extra weight on both the wallet and the environment.

To make sure we get all these benefits right out of the box without any issues like future leaks due to bad decking structures under existing roof material; a complete tear-off followed by fresh installation is recommended.

While installing metal panels directly over existing shingles may seem like a time-saving move, it adds weight and can lead to problems down the line. It’s always best to start with a clean slate when installing your new roof.

To ensure you get all these benefits without any hitch, hiring a reputable roofing contractor is crucial. In the Kansas City area? Pyramid Roofing got you covered. Our team of experts will make sure that your metal roof installation goes smoothly.

Key Takeaway: 


Reap the Benefits of Metal Roofs: With a lifespan of 40-70 years, metal roofs outlast asphalt shingles by decades. They’re safe in wildfires or lightning strikes and offer energy efficiency by reducing cooling costs up to 25%. As an eco-friendly choice with high recyclability, they help conserve our planet too. But remember, every roof comes with its own set of pros and cons. So it’s essential to weigh these factors carefully before making your final decision.

The Process of Installing a Metal Roof Over Shingles

Switching from shingle roofing to a metal roof can be an enticing prospect. But it’s not as simple as laying metal panels over your current asphalt shingles. Let’s delve into the process and understand why.

Potential Problems with Overlay Installation

Laying a new, shiny metal roof directly on top of old, weathered shingles may seem like an efficient idea that saves money upfront. However, this approach may lead to potential issues that could be costly down the road.

A crucial roofing concern is tracking future leaks or water damage. If you install metal over existing shingles without inspecting for any underlying issues first, pinpointing sources of roof leaks later becomes much more challenging because there are now two layers involved – your new metal cover and the old layer underneath it.

Tackling Decking Issues Before Installation

An integral part of any successful installation involves assessing and replacing bad sections of your roof decking if necessary before installing anything else atop them. A complete tear-off helps in detecting broken boards or signs of rot which can compromise your new roofing components’ integrity.

Weight Concerns When Layering Roofs

Another factor often overlooked is weight considerations when adding another layer to your current asphalt-shingle-covered home. Your building structure needs enough strength to handle extra weight added by a fresh layer.


Key Takeaway: 


Switching to a metal roof from shingles isn’t as straightforward as overlaying the new on top of the old. This could mask potential problems like leaks or deck damage and adds weight to your home’s structure. Therefore, proper inspection and preparation are crucial before installation. If you’re in Kansas City and need help with this task, Pyramid Roofing is ready.

Addressing Roof Decking Problems

When you’re gearing up to install a new metal roof, one thing that often slips through the cracks is checking your roof decking. The integrity of these wooden boards beneath your shingles can be the difference between a sturdy and secure home or unwanted water damage.

A thorough examination of the current decking should be conducted by your roofer to detect any wear or deterioration. If bad roof decking isn’t addressed before laying down those shiny new metal panels, it could spell trouble in more ways than one.

Damaged decking may not provide adequate support for the extra weight added by a metal roof. This can lead to structural issues and potential safety hazards down the line – definitely something we all want to avoid.

The Warning Signs: Identifying Bad Roof Decking

If you spot sagging areas on your current asphalt shingle roofs, it might indicate rotten wood underneath. Dark stains or streaks are also red flags pointing toward possible leaks that have soaked into the board over time.

You’ll need an experienced eye from Pyramid Roofing around Kansas City to get a free estimate, ensuring every corner is checked properly and replacing bad sections if needed because let’s face it; this isn’t DIY territory.

Repair vs Replacement: Making The Right Call

In some cases, minor repairs may suffice if only small parts of your decking show signs of rotting or moisture damage. However, when large portions are compromised – replacing them becomes inevitable. Your roofing materials must rest on strong supports; otherwise they lose their efficacy over time due to instability below. Check out our list here for some of the strongest roofing materials that withstand severe weather conditions and time.

A bad deck doesn’t mean you need an entire roof replacement. It does mean, however, taking action before those small issues become major problems. It’s wiser to take preventive measures than to suffer the consequences when it comes to safeguarding your house.

Key Takeaway: 


Depending on the severity of these issues, you may need to repair or even replace your roof decking. This is a crucial step because it’s not just about slapping a new metal roof onto an old, damaged base. You want to make sure that everything underneath is solid and secure. After all, what good is a shiny new roof if it’s sitting on top of rotten wood? Remember – when installing your metal roof, don’t just look up…look under.

Hiring a Reputable Roofing Contractor

When it comes to roofing services around Kansas City, Pyramid Roofing stands out. But why should you pick us? Well, because the right contractor can make or break your roof replacement project.

A reputable roofing contractor like Pyramid Roofing will recommend installing a new roof rather than overlaying an old one. It’s not just about saving money upfront; it’s about long-term quality and avoiding future issues.

We understand that replacing an entire roof might seem daunting, but here are some reasons why we advocate for this approach:

  • Detailed Inspection: We get the chance to thoroughly inspect your current asphalt shingle roof before we start laying metal panels over it. This lets us spot any existing problems such as water damage or broken boards in the decking that could lead to serious structural concerns down the line.
  • Better Performance: The weight of a metal roof added on top of your current shingles can strain your home’s structure. With complete tear-off and replacements, there is no extra load on your house frame, ensuring its longevity.
  • Saves Money Long-Term: An overlaid metal roof may save you money now but may cost more later when leaks occur due to underlying problems hidden by existing shingles.

It all boils down to trustworthiness. At Pyramid Roofing, our work speaks volumes about who we are and what values drive us – commitment towards excellence in service delivery, quality workmanship, and complete customer satisfaction.

Don’t just take our word for it – ask around. Good roofing contractors have a solid reputation in their local communities. They also uphold high standards of professionalism, are licensed and insured, provide written estimates, and offer robust warranties.

Understanding the Weight Considerations

If you’re considering a metal roof for your home, it’s crucial to understand how weight factors in. Many homeowners are surprised to learn that installing a metal roof over existing shingles adds extra weight, which can potentially cause structural damage.

The additional load of a new layer may seem minimal on paper, but every pound matters when it comes to supporting structures like your home’s framework and foundation.

The Heftiness of Metal Roofs

Metal roofs indeed have many benefits: they’re durable, low-maintenance, and offer excellent energy efficiency. However, their robustness also contributes significantly to their heftiness compared with traditional asphalt roofing materials. So before deciding whether or not to install one over your current shingle roof, remember this – there is such a thing as too much of a good thing.

Potential Structural Damage from Extra Weight

A structure designed only for lighter-weight asphalt shingles might struggle under the burden of both layers combined – kind of like wearing two heavy winter coats instead of just one. This double-layer approach could put undue stress on the building’s frame, leading to serious consequences down the line, including foundational problems or even worse – catastrophic failure. And nobody wants that drama at 2 am during a stormy night…

Evaluating Your Home’s Capacity

To avoid any unfortunate surprises later on, make sure you consult with a reputable roofing contractor who will conduct a thorough inspection, evaluating the overall strength and integrity of your house to determine its capacity to handle the additional loading imposed by newly installed metal panels on top of the existing ones, rather than tearing them off and replacing them completely.

Finally, let me share a piece of advice for fellow homeowners – while installing a metal roof over shingles may seem like a cost-effective solution upfront, always weigh the potential long-term risks involved. In the end, a thorough assessment and careful decision-making can save you from an unwelcome structural calamity.

Key Takeaway: 


Before deciding to install a metal roof over your existing shingles, it’s crucial to consider the added weight. This extra load can potentially cause structural damage to your home. A thorough inspection by a reputable roofing contractor will help determine if your house can handle this additional burden. While it may seem cost-effective initially, always weigh the long-term risks before making such decisions.
