Roofing systems made of metal make up a major chunk of the company's revenue. When it comes to building upkeep, you've probably come across a few buildings with metal roofs.
The problem of leaks in metal roofing is something you've probably encountered as a roof manager. Metal roof components are specific to different types of roofing systems. Therefore, different repair methods also require different approaches.
Metal roofs can be found on a wide variety of buildings. They see widespread use in residential developments situated atop mountainous terrain. In addition, they are frequently used in business and manufacturing facilities. Certain industrial buildings' metal roofing systems also serve as structural roof decks, preventing water from penetrating the building's interior.
Have You Experienced Roof Leaks On Your Metal Roof System?
If that's the case, know that you're not alone. Leaks are common in metal roofing systems in some climates.
They say that the devil is in the details. Particularly applicable to the setting up and repairing of metal roof assemblies.
Some frequent metal roof concerns include:
- Unclosed seams
- Exposed-penetration flashings
- metal roof oxidation
- Unsecured ridge/headwall flashing due to fastener backout
- The counterflashing is a little sloppy.
- Poor set-up procedures
- Damage to the panel
Let's take a look at some of the core design features of a metal roof system before we go into the common problem areas.
Metal Roof Systems: Structural vs. Architectural
Metal roofing systems can be put together in one of two ways, depending on the intended function: as an aesthetically pleasing design or as a strong and reliable structural element. The fundamental difference between the two kinds of roofs is the incorporation of a structural roof deck.
It is common practise to instal a structural roof deck separately, then instal an architectural metal roofing system on top of that. These sorts of systems are used in a wide variety of commonplace domestic contexts. Metal roof panels can be seen not just on residential structures, but also on commercial buildings like shopping malls and office buildings, where they are supported by a separate deck. One distinguishing characteristic of this design for a metal roof system is the use of a separate structural deck as support for the metal panels.
A structural metal roofing system is exactly what it sounds like: a roofing system made of metal. However, in this design, the metal roof panels serve double duty as both the roof's structural deck and the building's waterproofing system. These metal roofing systems are standard on prefabricated metal buildings.
These metal roofing systems rely heavily on clips during assembly and assembly. All the panels are fastened to the building's horizontal purlins with these clips. Batten insulation is commonly installed above purlins before metal panels are installed.
Comparing Hydrostatic and Hydrokinetic Structures
Metal roofs are easily recognisable due to their slope, which is a characteristic design feature. Metal roofing systems can be constructed with either very steep or very shallow slopes, depending on the needs of the building. However, metal roofs can experience serious problems if the roof's pitch isn't taken into account.
It is imperative that the roof's pitch be taken into account during the planning, installation, and upkeep of a metal roofing system.
Metal roofs designed for hydrostatic drainage absorb rainwater and hold it until it can be drained away. Because of this, water may be collected and stored without posing a threat to the integrity of the roof. These metal roofs are typically seen atop big pre-engineered metal buildings.
It will be more expensive to create these larger buildings with a steeply sloped roof assembly. However, there are various types of hydrostatic metal roofing systems that are sometimes used in residential construction. Tin and copper metal roofs can be installed using a soldered flat seam hydrostatic technique.
Hydrokinetic metal roof assemblies are intended to be watertight. These tools were designed for usage on challenging terrain, such as steep inclines.
Steeply sloping systems are commonly used in residential and commercial settings where water cannot be permitted to pool on the roof. When water collects on a roof for an extended period of time, hydrostatic pressure builds up and pushes water into the roofing system's details, leading to leaks in metal roofs.
Metal Roof Leaks.
Mistakes in the design and installation of a new metal roof might cause serious issues later on. In most circumstances, however, problems do not arise in the process of selecting the system itself.
Most problems that cause leaks in metal roofs may be traced back to the finishing touches that are used to instal the roofing. Once the installation is complete, you won't be able to see these mistakes. They could require some extra time to grow up.
The following are the top five problems discovered while checking the state of a metal roof.
Holes on the side seams
Sometimes it's impossible to fabricate metal roof panels that are long enough to cover an entire building's rafters. For this reason, the designer of the project may decide to place constraints on the total length of the panels to account for thermal expansion and contraction.
Panel length restrictions necessitate horizontal seams in the roofing system, else the job cannot be finished. The metal roof's standing seams are oriented at right angles to these horizontal seams.
The tendency of horizontal seams to come apart increases with time. Hydrostatic metal roof systems are vulnerable to this because it can cause a leak in the roof, allowing water to seep back in after it has been drained.
Signaling Penetration Holes
Metal roofing systems can swell and shrink with the weather. As a result of temperature shifts, the metal panels have shifted, resulting in the damage. As a result, the roof's attachments and any openings in it experience strain. Leaks have developed at roof penetrations where flashings have deteriorated as a result of the stress.
During the assembly of a metal roof, the seams between individual metal panels serve as fasteners. It is quite difficult to disassemble a metal roofing system once it has been installed.
Unfortunately, unlike an asphalt shingle system, they cannot be taken apart and used to fix the flashing around roof penetrations. This makes it more difficult to address long-term repairs, especially if the puncture was added after the metal roof was first built.
Rust on the Roof
Metal roofing can be made from a wide range of different materials. Metals like iron, aluminium, tin, copper, and zinc are examples. Metallic steel is incorporated as well. Some of these materials are susceptible to oxidation. Almost all metal roof panels are made from sheet metal that has been coated to prevent water damage. In time, this coating usually wears off, exposing the metal panels to oxidation.
Sometimes issues arise when the surface oxidises. If the metal roofing system is also a structural system, then structural failure could be an issue. Also, oxidation makes repairs more of a hassle. Sometimes it's hard to get a good seal because the metal panel has oxidised at the fastening heads.
Unscrewing Bolts
There is often a combination of both exposed and concealed fasteners in metal roof construction. These fasteners could be nails or screws. Typically, a neoprene washer will be used to create a watertight seal between the exposed fastener's head and the metal roof panel.
Fasteners tend to stand up from a seated position as time progresses. Several hypotheses have been proposed to account for this observation. Some fasteners may loosen due to wind uplift. Metal panels in the open air will vibrate and eventually lose their fasteners if the wind is strong enough. Fasteners might loosen due to the freezing and thawing process.
When the neoprene washer dries out, water may be able to get through. In the winter, the water's increased probability of freezing and expanding increases the possibility of the fastener coming loose.
The Flashing of the Open Ridge and Headwall
In some cases, the exterior of the building must be reached by roof systems via a different type of termination. One of these features is sloping wall detailing at the points where the roof meets the walls or ceiling. For instance, a shopping mall with a metal roof and a rising wall below a band of advertising would fit this description.
This is where a flaw is most likely to show up. Often, this is the result of sloppy work done during the first installation. Water can't be allowed to blow back into the detail by using closure strips in this situation.
Putting in this sealing strip is optional for the contractors. It is the underlayment's first function to prevent water from getting through to the roof deck during blowback. If the underlayment ages, moisture can seep through and damage the roof.
Leaks on metal roofs can originate from a wider variety of causes. These five are good representations of widespread resources that should be consulted initially. Nevertheless, recognising the existence of possible leaks is only half the battle; the other half is actually locating those leaks.
Let's have a look at the options available for fixing or replacing metal roofs.
Metal Roofing Leaks: What Can Go Wrong?
Metal roofing typically incorporates copper, aluminium, zinc, or one of three types of steel. Among the many available options for this roof is a standing seam metal roof.
There is a wide range of metal roofing systems available, each with its own set of pros and cons. However, metal roofing is among the longest-lasting options because of how well it resists rust and fire.
The metal roof on your house, if properly installed, should not need major repairs or replacement for a very long time. Depending on the quality of the paint used, a painted metal roof can last anywhere from 40 to 70 years with no maintenance. The bulk of its initial reflectance and emittance should likewise be maintained for about the same period of time.
The most important thing to remember if you find a leak in your roof is that it has nothing to do with the metal you used or the quality of the metal. The installation is typically the starting point for troubleshooting.
Inadequate Fastenings
When installing metal roof panels, you can use either clips or rubber washer fasteners to keep them in place. Each of these two categories of fasteners is unique. Clips are attached in such a way that any overlaps in the metal seams are concealed. In addition, a sealant (often acrylic or urethane) is used to permanently bond all of the metal roofing panels together.
It is possible to drill less frequently (as often as once per two square feet) when using fasteners with rubber washers. Placement of the metal panels in close proximity to one another keeps the seam laps smooth without the use of sealer or butyl tape.
These fasteners loosen with time, leaving potential gaps or holes in the metal seam laps. As a result, not only can water seep through the cracks, but it also lays the way for future issues to occur as a result of the initial one.
Standing seam metal roofing systems are more superior at keeping a tighter seal than other types of metal roofing.
Paneling Is Missing Or Poorly Fastened
If the panels on your roof weren't securely fastened, they may shift or even be blown off in a storm. This occurs when the fasteners, about which we just spoke, are not properly tightened. It's also important that the metal roof's panels fit snugly and securely together. Without proper safety measures, you risk losing important parts over time.
Most metal roofing materials, when installed correctly, can withstand gusts of up to 110 mph. In contrast, if you see that pieces of your metal roof are breaking off, it's probably because the installers didn't do a good enough job.
Splits in the Seams
If you're installing a metal roof, check that all of your seams are secure and flush. If the joints aren't correctly sealed, water can seep in and cause leaks in your roof.
Open seam laps on a metal roof will not only lead to leaks, but also have the potential to create structural damage, which can cost you a lot of money and bring you a lot of hassle in the long run.
Disjointed Bits and Pieces
Parts of your metal roof may become dislodged due to sustained high winds, storms, debris, or even deterioration. Your metal roof will eventually rust and corrode, even if you live in a climate that rarely has severe storms (like our hometown of Youngstown, Ohio).
Water seepage or leakage can occur when extra physically critical pieces are not installed properly. This class include foam seals, vent flashings, boots, downspouts, gutters, and edge metal.
Plumbing vents and HVAC curbs, for example, are considerably more likely to come apart if they weren't installed using the proper materials and sealants, allowing the elements inside the property.
A Rusty Finish
Depending on the coating you apply, rusting may become an issue for your metal roof sooner rather than later. When metal is exposed to air and water, rust forms as an inevitable byproduct. It's good news that rust isn't always an indication of leaks.
Rust on metal roofing, however, is cause for immediate attention. If not stopped in its tracks, rust can rapidly spread and inflict extensive destruction. Eventually, the coating will flake off, the metal will scale, and the holes will be eaten away by corrosion. Because of all of these potential causes of structural damage, it is imperative that all of these risks be taken seriously.
In order to stop the rust from spreading, a rust inhibitor must be used. It won't stop the rust from happening or even significantly slow it down, but it will afford you some time to make the necessary repairs.
Splits and Tears
Rust is the only guaranteed way to get holes in your metal roof, but there are other potential sources of damage. Surface damage, such holes and punctures, is a common effect of foot traffic that involves the dragging of heavy goods.
For instance, the installation of a heating, ventilation, and air conditioning system might cause considerable disruption. This is because HVAC systems are bulky and cumbersome, and dragging one across a metal-paneled roof would cause scratches, dings, and punctures.
Deflection, which looks like a crimping or creasing of the metal panels, could also occur as a result of this. A deflection can also result from bending. When this happens, water is more likely to collect in the area of the deflection, which can lead to rust. As a result, you shouldn't wait for a leak to appear before checking the work done on your metal roof.
Changes in the Water
It's possible the leaks you're experiencing are related to the patch repairs you had recently made on your metal roof. You may have caused the situation by attempting to cure a roof leak with a patch job. Water should be able to easily run off of the roofing system, therefore its design should take that into account.
Water will pool and become stuck in the area where the roof was patched if the materials used to do so do not allow for the necessary elongation. That's why it's important to always utilise flexible materials when repairing your roof. They will continue in the same fashion as the other metal sheets.
Material Incompatibility
Metal roofing systems necessitate the use of anti-oxidant and anti-corrosion compounds. The ability of metal roofing to maintain its watertight seal can be compromised by the presence of corrosion or oxidation, which can occur when certain metals are employed together.
To prevent water damage to your structure, make sure the flashing around its weaker points is properly installed using high-quality materials. Skylights, vents, and other openings of a similar nature are common places to look for a leak. It's unfortunate, but using the wrong metals and sealants on your metal roof will actually weaken it.
When working with sealant, an acrylic or urethane coating is recommended. These alternate options not only help stop rust from accumulating, but they also help seal the area where leaks typically occur. Instead of using a sealant, butyl tape can be utilised in some instances.
What are the most frequent issues with metal roofs?
After your metal roof has been installed, you may face the following challenges. Although it is common knowledge that such roofs are durable and energy-saving, regular problems can still arise at any time.
Metal roofing has a number of drawbacks, including those listed below.
Leaking
The leaking of a roof might be a major issue if you reside in an area that regularly has heavy weather. As a result, the roof is at risk for numerous problems. It's possible that the leak could spread to the walls, ruining the paint, texture, and other finishes. Additionally, if the bolts that hold the metal roof together are left exposed to the air, leaks in the roof may develop.
In most cases where problems arise, it is because the roof was improperly installed. Possible causes include improperly constructed seams or poorly placed screws. Leaking is expensive because it requires not only fixing the roof but also the walls and any other damaged parts of the house.
Scratches
The most common problem with metal roofs is their susceptibility to scratches. There's a wide range of situations and actions that could trigger this. While preparing the product, it is crucial that the manufacturers take extra care to avoid damaging the surface. Companies involved in transportation also have a higher duty of care.
It is equally important to avoid dropping or rubbing the metal sheets or panels with any equipment during installation.
After the installation is finished, you should avoid walking on the roof to prevent scratching the surface. The metal sheets can't be moved or shipped without first being protected from damage by edge guards. The employment of listing devices is mandated to reduce the possibility of damage from scuffs and scratches.
Bottling Oil
Aluminum, copper, steel, zinc, etc., metal roofs are a good example of this. Oil canning on a metal panel shows up as wrinkles or waves and is usually the result of tension. Stress is mostly brought on by the material's being coiled, rolled, or sliced repeatedly.
This can also happen when seasonal temperature variations cause expansion and contraction, but not enough room is available. This phenomenon, which results in the flat appearance of the metal roof being compromised, is sometimes referred to as elastic buckling.
Many Types of Corrosion
Metal roofs may be resistant to corrosion, but there are still various types of corrosion that can occur on them. When the coating isn't placed properly, water can become trapped under the panel. This could lead to corrosion of the metal sheet, which could lead to damage. Consequently, those who live near the seaside should be careful about the metals they employ in their construction projects.
Having salt water nearby means the roofing will corrode more quickly. Metal roofing made of aluminium or zinc can be ideal for such dwellings. Yet, galvanic corrosion of the metal roofs is a distinct risk.
This occurs when two different metals come into touch with one another and react in the presence of water or electrolytes. In this case, the more reactive metal will corrode, leading to the destruction of a roof section.
Effects of Chalking and Color Loss
The roof will always be exposed to air and sunlight, no matter where in the world your home is located. Chalking and colour fading are typical results of being exposed to UV rays. Roofs often develop a white film known as "chalking" as UV radiation from the sun degrade the paint resin.
Fading occurs over time because paint pigments are easily broken down by environmental elements like water and UV light. Exposure to environmental contamination over a long period of time is another potential contributor to this illness. In most cases, the local environment will dictate how much discoloration and chalking will develop. Cleanliness and pollution levels are two other important considerations.
Installation Errors
Many problems with metal roofs are caused not just by environmental conditions but also by shoddy installation. Issues with the roof's endurance can stem from a number of sources, including loose screws, poor fitting or finishing, and shoddy attachments.

How To Solve Metal Roofing Problems?
Contacting Houston, TX roofing contractors is the best option, but we found these other methods recommended by the top Houston roofing companies.
Because of Spilling
Checking the condition of the metal used in the roof is essential for detecting and fixing leaks. Additionally, if you fit everything down tightly, any leakage damage will be minimised.
Reasoned Use: Scratching the Roof
Scratches in a roof can be easily concealed by applying a layer of paint that is the same colour as the roof. This, however, is pertinent in the case that the harm is quite little. Still, if large dents or scratches have been made in the roof, it will be time to get a new one.
When Preserving Oil
Choose thick metal sheets made of a material with a low shiny finish for oil canning. Both the occurrence and public awareness of oil canning are diminished in this way. The sheets can only be slit using a ribbed roller along the flat edges.
Against Corrosion
Since corrosion comes in numerous ways, preventing it requires both choosing a suitable metal for the roof and covering it with a protective material. To further reduce corrosion, don't ever swap between metal types.
To Be Used With Chalking And Color Fading
High-quality adhesives must be used to prevent the colour from fading and chalking. Most manufacturers also offer warranties that, depending on the extent of colour loss and chalking, will restore the roof to its pre-damage condition.
Choices for Fixing or Replacing a Metal Roof: Repair, Restoration, or Substitution
There are essentially three options open to building owners and managers when dealing with their roofing systems. They can either restore the current roofing system or instal a completely new one.
So, when you have a metal roof that is leaking, you'll need to decide whether to fix it, restore it, or replace it.
Fix Up And Keep Up With
Metal roofs can be fixed or kept in good condition with regular maintenance and repairs. The expected lifespan of these roofs may be thirty years or more if they were installed properly. For this reason, it is recommended that metal roofing systems be evaluated at least once every two years.
Metal roofs require regular inspections to ensure they are being cared for properly. Finding problems before they become catastrophic is always the best course of action. When problems like oxidation are detected early on, they can be fixed cheaply. Leaks can be avoided and general roof care and maintenance can be improved by simply looking for loose fasteners and tightening them.
Restoration
Leaks are more common in an older metal roof compared to a brand new one. Eventually, a more broad scope of repair work will be required due to the frequency of leaks and the general state of the roofing system. The roof will continue to deteriorate if no action is taken to restore it. There is a limited window of opportunity to implement a restoration programme before it becomes necessary to replace an item.
There is typically a set order of operations that must be completed while restoring a metal roof. These include fixing the issues we've already discussed, such putting a rust inhibitor on the metal or replacing the fasteners. There may be a need for further work on the penetrations and details. A coating should be applied to the roof's surface after any necessary repairs are made.
You can pick between two primary categories of coating materials. They are acrylic and urethane paints. Both of these options are viable considerations when thinking about metal roof restoration. In the process of formulating a restoration strategy, however, it is important to keep in mind the limitations of each of these choices.
Replacement
Changing out metal roofs with the metal retrofit system is a modern innovation. This system is used to replace an existing low-slope metal roofing installation. Typically, this system is installed over an already-in-place structural metal roof, which acts as the metal deck for the new roof.
A Description of the Methods at Work
Before installing the metal retrofit system, an insulating board is inserted into the cavity created between the metal ribs of the panel. This creates a flat surface. To create a firm base for the roof membrane to adhere to, an additional layer of insulation board is installed after the infill has been laid. Finally, the installation of a brand-new single-ply membrane has begun.
A Standing Seam Imitation
Although a metal roof's aesthetic appeal is often sought after, it is sometimes impossible to have the system installed owing to adverse weather or other factors. It may not be possible to utilise a regular metal roof panel, for instance, on a job with an unusual layout or a deck surface that cannot accept nails.
Single-ply manufacturers have created imitation standing seam roofing systems to meet the needs of these one-of-a-kind projects. The system incorporates a regular PVC roofing system. The final step in the installation of a standing seam roof is to attach a simulated rib of seam metal along the roof's top surface. While it looks like a standing seam, this has all the benefits of a single-ply membrane.
Old-Fashioned Metal Roofing
Metal roofing's durability, longevity, and versatility make it an excellent choice for a wide variety of building types and designs. Standing seam metal panels and metal roof shingles are only two examples of the many different types of metal roofing panels available. Which application is best for a given project or structure will depend on its specifics.

Frequently Asked Questions About Leaking Metal Roof Problems
For metal roofs, a high-solid polyether or silicone sealant is best. Many of these are pigmented to match popular roof colours, so they blend in and form a solid seal.
The majority of leaks on metal roofs are caused by leaking roofing screws. Metal roofing screws keep water out by compressing a rubber washer at the base of the screw head. When the screw is inserted into the metal roofing plate, the rubber washer creates a “gasket” between the panel and the screw head.
Signs That May Indicate a Leak in a Metal Roof
- Rust on the Surface of the Roof.
- Improper Roof Movement.
- Issues with Fasteners.
- Holes or Crimping in the Roof.
- Improper Materials or Installation.
- Body of the Roof.
- Transition Points.
- Roof Penetrations.
For a metal roof system, a silicone sealant is preferred as it adheres well to metal and other common construction materials. It also offers excellent moisture and UV protection and features exceptional joint movement capabilities.
It is safe to seal a roof with Flex Seal. Flex Seal is applied to damaged roofs to fill gaps and prevent leaks. It forms a solid bond to the shingles, tiles, or metal on your roof that keeps water out. Also, Flex Seal can form a protective seal for years to come without harming the roofing.
