Your Commercial Metal Roof Might Be Leaking Because of These Three Reasons

There are different types of roofing options in the market. There is asphalt shingles, clay tiles, slate shingles, green roof, etc. However, if there is a roofing option that lasts longer, requires little maintenance, stands up to all weather conditions, and cuts down energy costs, it is the metal roof. But, all these qualities do not make metal roofs indestructible. These roofs can leak too. In this blog, we will take a look at common reasons why properly installed metal roofs can leak. Let’s get started!

Screws Driven In The Metal Roof

You will be surprised to know that most leaks in metal roofs are caused by roofing screws. The job of the screws is to form a seal so that water stays out. It achieves this by pressing a rubber washer present at the base of the screw head. A sort of gasket gets formed between the roofing panel and the screw head when a screw is driven into the metal roof panel. Properly driven screws form a proper gasket but under driving screws, driving screws at an incorrect angle, overdriving screws, or screws that miss the framing member, all allow water to penetrate through the metal roof.

Stack Flashings

Many commercial metal roofs leak through the stack flashings, which are basically flashings around the pipes that go through the metal roof. Many things go through your metal roof such as plumbing pipes, HVAC vents, air vents, etc. The job of the stack flashings is to waterproof the pipe by creating a seal using its rubberized material. These flashings form a double seal. One is formed by staying flat on the metal roof surface and another one is formed by squeezing the pipe from all sides. Although these seals are strong, constant expansion and contraction of the metal roof make them weaker over time. Also, the rubberized material degrades over time under direct sunlight. You should replace old stack flashings to keep your building dry.

Worn Out Sealants

It has been found that metal roof sealants that are installed together with the metal roof do not hold out as long as metal roofing panels do. They need to be changed with regular roof maintenance. You need to fill up sealants around areas such as roof transitions, metal ridge caps, counter flashings, Z flashings, pitch pans, etc., as they all wear with time. It is therefore essential to use only sealants that are specifically made for metal roofs. As we all know, metal roofs expand and contract. If you want sealants to last longer and offer protection against water penetration, you must only use sealants that are flexible and can stretch with the metal without breaking their seal.

So, there you have it. These are some of the most common causes of leaks in metal roofs. You can get in touch with a reputable metal building contractor like the Metal Guard for getting your metal roof inspected for leaks and their possible causes. Proper metal roof sealing is essential for keeping water out of your building. With the help of an experienced metal building contractor, you will be able to seal your metal roof in the correct way.

6 Preventative Tips To Prevent Leaking Metal Roof Situation

In the crowd of clay roofing shingles, high-density slate, and synthetic thatched installations among the popular roofing choices, metal roofing has slowly yet claimed its spot across every Texas home. Considering the high functionality, durability, esthetic versatility, speed, and ease of installation, the one-time high installation costs are now being overlooked by homeowners. People can see the long-term benefits of metal roofing. However, preventative maintenance care is a must even for the sturdiest metal roof installation. People often tend to let go of any maintenance measures thinking that it’s “metal” (read: sturdy and invincible). This causes dangerous leaking metal roof situations and premature roof failure across different structures.  

Being in the metal roofing industry for over 20 years, in most cases, the major roof repairs we undergo could have easily been prevented with a little bit of TLC. Here are our top expert-recommended tips for you:


Clean your metal roof regularly to get rid of stains, dirt, leaves, mildew, and other debris. Apart from looking unappealing, it also ruins the paint system of your metal roof.


Your gutter system includes downspouts and drains boxes. The clogging of drains and gutters can lead to water overflow, increasing premature corrosion for every metal roof material.


Elements of nature include tree twigs, branches, leaves, stones, among many other things. If left unattended, their degradation can ruin the material of your roof, leading to metal roof leaking, falls, scratches, denting, among other severe roof issues.


Corrosion is the worst enemy for every metal. It’s like cancer for metal roofs. The most vulnerable spots for corrosion are around chimneys, HVAC vents, air conditioner installation spots, or any other oil condensers above cooking areas. Excessive steam, heat, and chemicals can break down the protective paint layer and lead to corrosion.


Houston is home to more extreme weather conditions than other US states. Therefore, a professional maintenance inspection is a must to overcome the impact of torrid weather conditions. Your location plays a role in deciding the frequency of scheduled maintenance. If your home is lying under the shade of trees, you will need to call for professional inspections at least twice a year (or every six months). Speaking from experience, this is way less expensive than the repair you will probably require if you forego this point.


Damaged roof parts may include loose flashings, fasteners, loose sheets, closures, ridge caps, venting materials, and more. Cracks, penetrations, dents, and seams in your metal roof will fail to prevent water entry, thus leading to a leaking metal roof. Make sure to take assistance from reliable professionals to cover up any holes and cracks with a quality roof sealant.

Aging, severe weather events, among other factors, can decrease the longevity of your metal roof. A regular maintenance schedule with a reliable team of experts preserves your investment while saving your time and efforts for repairs keeping up the appearance of your metal roof.

You Might Have To Replace Your Commercial Metal Roof If It’s Showing These Signs

There is no doubt about the fact that metal roofing is one of the best commercial roofing options in the market. It is known for its durability and insulation properties. However, it would be wrong to assume that your commercial metal roof won’t need replacement. Albeit late but your metal roof will need to be replaced at some point. You can surely extend its life by making sure it is installed properly in the first place and by following its maintenance requirements. Below, we have listed some common signs that indicate your metal roof has served its time.


Signs of rust tell a lot about the condition of a metal roof. Firstly, it is a clear indication of tarnish. Secondly, it shows that the protective coating of your roof has worn off. As soon as the coating or finish gets deteriorated, water and moisture will start to come in contact with the metal, which needless to say, causes rust eventually. It is essential to get your roof inspected at fixed intervals so that signs of rust are noticed well before leakage starts to happen. Many commercial building owners get to know about rust only when their roof starts to leak. When getting your roof inspected, make sure areas such as ridge caps, flashings, skylights, seams, fasteners, vents are especially examined.


It does not matter whether your metal roof is leaking a little or a lot, we will advise you to contact metal roof experts straightaway. It is true that most leaks are caused by rust, but there are many other possible causes of metal roof leaks. For example, warped or loose panels can easily allow water to penetrate through new openings. It is essential to understand that at first, water leakage might not look like a serious problem. But if ignored for long, it can cause damage to building materials, electrical systems, and create conditions for mold to grow.

Loose Panels

We have already mentioned above that one of the causes of water leakage in metal roofs is loose panels. Your facility can get damaged due to loose panels caused by high winds, storms, and warping. You might not know this but thieves, who usually enter facilities through windows and doors, can also make their way inside your facility through loose panels. Not just thieves, rodents, and other animals can enter your facility through loose panels. Birds can form nests in the ceiling or the wall of your facility, which can pose safety and health hazards.

Even the most properly installed and well-maintained metal roofs are given in extreme weather conditions and age. If you notice any of the above-mentioned signs in your commercial metal roof, get in touch with Metal Guard immediately. We will properly inspect your metal roof to ascertain whether it needs to be repaired or replaced completely. For professional commercial metal roof repair or replacement, look no further than MetalGuard.

Is Your Metal Building Energy Compliant?: Tips From Expert Metal Building Insulation Suppliers

With the energy-efficient building market to develop at an 8.17% CAGR (by 2027), the concept of green in construction and architecture has claimed its space for good within the economy. Metal structures are a popular choice among architects and construction engineers due to their design flexibility, high value-to-cost while being cost-effective for practical and aesthetic purposes. With the site and labor costs rising each day, metal offers a more affordable solution for meeting large site requirements such as warehouse needs, contemporary-styled performing arts center, or even a traditional-style church. However, the impeccable conduction power of metal makes it difficult to keep the heat out. This makes the occupants and sensitive components stored within the building vulnerable to extreme temperature shocks or other types of damage.

This further makes building insulation more difficult while leading to higher energy consumption to maintain a comfortable environment. With governments worldwide putting an increased emphasis on zero-energy buildings, the IECC (International Energy Conservation Code) outlines a set of energy codes for all metal buildings. Here’s what you need to know:

Checking Compliance With The Energy Codes

The IECC sets ground rules and standards for states while outlining guidelines for building design, materials, and performance related to the energy efficiency of buildings and structures.  

The code covers every aspect of the building, including walls, windows, doors, panels, insulation, HVAC system, power and lighting, ventilation, and even air leakage.

Depending upon your regional zone ( location-wise segregation from 0 to 8 with eight being the coldest) and type of building, your energy requirements must be fulfilled.

Pro tip from our metal building insulation suppliers: Run an energy audit with the help of an expert to correctly estimate what’s costing you per month.

The standard formula for estimating energy compliance is the R/U ratio. R refers to the resistance of a material to let heat pass through it, and U refers to the amount of heat or cold passing through a system. The higher the R/U value, the better the energy standards.

Additionally, professional metal building insulation suppliers also use continuous insulation (ci) and linear systems (ls) on the exterior and interior of a metal building for adequate insulation.

With that being said, here are a few ways to make your metal building more sustainable and energy compliant:

  • Install a cool roof to decrease the burden on your AC system.
  • Plug air leaks to prevent the mixing of outer air with your inner environment.
  • Invest in renewable energy sources such as solar energy, wind turbines, and geothermal heating systems to reduce your dependency on electricity.
  • Incorporate rainwater harvesting tanks and switch to tankless water heaters.
  • Go for the highest R-value insulation to maximize energy savings and maintain a comfortable inner environment.

The points mentioned above are more of a generalized solution for energy compliance. Depending upon your building structure, location, and usage, a professional building contractor can provide more accurate suggestions as per the level of insulation needed by your building structure and combinations that will be more effective. Besides, it’s always cheaper to move under the proper guidance than to circle back and re-do them.

3 Common Commercial Metal Roof Problems

Standing seam metal roofs are quite popular as they last for a long time, look modern, and protect the structure pretty well. For this type of metal roof, aluminum serves as the best base metal material. Aluminum is known for being a greener alternative, its durability, resistance to rust, and its energy-efficient properties. In spite of being so good, aluminum standing seam metal roofs can sustain some damages. With the help of an experienced metal building contractor, you can fix those damages by understanding the causes. In this blog, we will tell you what common problems you can face with standing seam metal roofs. Let’s get started.


Rust and corrosion are common problems with any galvalume or galvanized steel metal roof. Usually, water and water-borne pollutants are the culprits responsible for the problem of corrosion. You can bring down the risk of rust by inspecting the water-resistant paint on metal roofs at fixed intervals. As soon as the coating becomes damaged or worn out, metal roofs become susceptible to corrosion. Also, moisture can makes it’s through the metal if an open edge of the metal is left exposed, which usually happens when metal roofing material is cut during installation.

Worn Out Fasteners

Your standing seam metal roof will stay in its place with the help of fasteners. In most cases, galvanized clips and screws are used to hold the galvalume and galvanized metal roofs in place. Although these clips and screws can hold the metal roof, the problem with them is that they cannot last for a long time as they go down in quality and become corroded as soon as they start coming into contact with moisture. That is why it is advised you should always use top-quality clips and fasteners for properly installing a metal roof.

Scratches And Punctures

Over time, debris from trees and snow can scratch up your standing seam metal roof. If those scratches are left unattended for a long time, it won’t take long for your roof’s durability to go down in quality. As we all know, there is a protective coating on metal roofs. If the coating gets scratched way too much, your metal roof will become jeopardized. Your metal roof will start leaking if punctures get formed. That is why it is recommended that you get your roof inspected at fixed intervals so that you can know in time when to cover it up or replace it.

So, there you have it. These are some of the most common problems that you might face with a metal roof. There can be many other problems as well.
