Metal Building Roof Inspection Process

Metal roof repairs include thorough inspections. The Metalguard team got down on their hands and knees to find this leak in the metal roof. One issue we found was a crack on the top of a high metal rib.  The rust around the two slits, indicates the metal roof panel damage occurred some time ago.  The top of the metal high rib is a small area 1” wide, consistent with expectations for a small leak. Our team caulked the crack in the metal roof to restore the metal roof panel integrity.

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.

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.

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.
