Metal Roof Repairs and Maintenance

As an experienced metal building contractor, Metalguard can diagnose your metal roof issues and develop the best solution for you. We can replace or repair only what is necessary. Not all metal roofs require a complete replacement. Therefore, sometimes the most effective solution for our clients includes a partial metal roof replacement, and repairs on the rest of the existing metal roof. This extends the life of the metal building and provides the best value for client.

Metal Building Repairs

These photos show a current Metalguard project that involves replacing part of the metal roof. This metal roof was leaking, so to fix the issue, we sealed the lower metal roof and upper metal roof. First, because of a previous coating, we installed a larger amount of new material to cover the old material.  Then, on the rest of the existing metal roof panels our team sealed the fasteners. The photos show the repaired metal roof. The light colored areas are new metal roof panels, and the white dots are sealed fasteners. Replacing where necessary, and repairing the rest of the roof represented the best value for the client.

We recommend fixing broken metal roof panels and performing maintenance as needed to extend the life of your metal building. Fixing the broken sections of the metal roof and performing maintenance on the rest, results in extended life for metal buildings.

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.

Metal roof inspection discovered this crack in the metal roof. Our team caulked the crack.

Metal Roof Repairs

Our metal roof inspections revealed one more cracked panel in the same area. This cracked metal panel is at the ridge cap and in the middle you can also see a very small crack.  For a roof this large a small problem like this can be hard to find without the help of our team, or a heavy rain.

Metal Building Tilt Wall Repair

Metalguard has extensive experience repairing metal buildings damaged by severe weather events such as hail, tornados, and hurricanes.

For this project, Metalguard was called in to repair a tilt wall supporting a metal building roof for a customer in Houston, TX. Several feet of water fell within a short period of time during a tropical storm, overwhelming the small roof drains and collapsing the metal roof.

Metalguard deployed a custom engineered solution including shoring up the metal roof, bracing exterior metal wall panels, and installing wall channels.

This picture shows where the beam landed on the stack of sheet rock. The white spot on the wall is the hole the beam made.  The groove above is where the beam was bolted before it fell.
The beam slid down about 12 inches and created this hole in the tilt wall.
We built this shoring device to brace the metal roof for repairs.
Custom built shoring device to hold up the metal roof.

We installed exterior wall braces.
The inside concrete wall was bowed out. Our team installed these channels to straighten and strengthen the wall

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.
