What to Know About Materials Shortages in the Roofing Industry

A perfect storm of supply chain issues has spurred unprecedented shortages in roofing as well as the construction industry at large. These problems are widespread, affecting countries across the world and almost every type of construction material. As a result of materials shortages in the roofing industry, many construction companies are unable to deliver their usual level of service. Materials have become more expensive and are taking longer to produce. The delays are also highly unpredictable, leaving companies unsure of when they will be able to complete a job or how much it will cost. 

Here we will explain what is happening and why roofers around the world over are struggling to perform their work as usual.

Supply and Demand Issues

Shortages in steel, lumber, and chemicals used in construction are driving up costs. Steel and lumber shortages first began to appear in 2018 as a result of tariffs on imports from China and Canada. This created a backlog of producers in need of materials before the pandemic even hit. Then, in 2020 when COVID-19 appeared on the scene many manufacturers and other providers of raw materials (like sawmills, steel manufacturers, and chemical plants) drew down their production due to uncertainty. Some of these businesses closed for good, and those that have reopened have not been able to secure the raw materials they need to quickly ramp up production to meet their increasing backlog of orders. 

These shortages in roofing material are overlapping with a huge surge in demand for homes and other buildings following the pandemic. There is an increased demand for homes spurred by people moving during the pandemic, and many projects delayed in 2020 are now getting underway.

Panic buying by contractors unable to secure construction materials has also inflated demand and compounded delays. Many construction companies are double ordering materials in hopes of securing them sooner and instead are creating confusion with manufacturers. 

Transportation Issues Are Causing Delays

The pandemic contributed to a slowdown in global shipping, which has contributed to a shortage of shipping containers in the U.S. This has slowed trucking and transportation in rail, making the delivery of roofing materials much less reliable than in the past. Even when a company does manage to secure materials for construction, they are often delayed or rerouted.

Before the pandemic, the delivery of materials from Asia used to take about seven weeks and was very reliable. Those same shipments are now taking 24 weeks if the materials can be secured at all.

Gulf Storms Have Slowed Production and Disrupted Transportation

Ice storms, hurricanes, and even a fatefully placed lightning strike have all conspired together to disrupt petrochemical production in Louisiana. The state is a global hub for these materials, which are used in nearly every type of roofing system. Storms halted chemical production at some facilities, leading to skyrocketing prices and shortages. Major hurricanes, like Ida, also disrupted shipping and rail transportation of other materials. 

Roofing Companies Are Struggling to Ensure Normal Service

All of these global issues are making it difficult for roofing companies to follow their normal processes for price and delivery estimates. Delivery dates on materials are no longer guaranteed, so roofers can’t estimate when they can get the job done. Since prices continue to skyrocket, roofers have been unable to accurately estimate the cost of jobs that will occur later in the year.

A Look at the Various Types of Commercial Roof Materials

No two businesses are alike, and neither are any two commercial roofs. Commercial roofs will differ from each other from the equipment they hold to the type of materials that make up their composition. Every kind of roof and roof material has its pros and cons. 

Here, we will look at some of the most common types of materials used on commercial roofs and explore the advantages and disadvantages of each one:

Polyvinyl Chloride Membranes

Known in the roofing business as PVC, Polyvinyl Chloride Membranes are one of the most popular commercial roofing materials. PVC roofs are made up of two layers of roofing material with a polyester layer in the middle for reinforcement. PVC is popular because it is extremely durable and long-lasting. It is also resistant to fire and moisture. The main downside is that PVC can be expensive compared to other roof materials. The material can also be difficult to repair when it ages.

Ethylene Propylene Diene Monomer

EPDM is commonly known as rubber roofing. This roofing material is easy to install, lightweight, long-lasting, and is one of the most inexpensive roofing materials. While EPDM roofs will last a long time in perfect conditions, they do puncture easily. Rubber roofs can also spring leaks easily if they are not properly adhered and leaks are difficult to detect in this material. EPDM is also not considered to be very aesthetically pleasing for buildings where the roof will be visible.

Metal Roofs

Many different kinds of metal can be used in commercial roofing from copper to galvanized steel to aluminum. Each type of metal has its own advantages and disadvantages but, generally, metal roofs are among the most durable and long-lasting roof options. Metal opens up a whole world of design options for a building, and the material is usually used for buildings where looks are a concern. Metal roofs also tend to be more fireproof than other types of roofing material, but it can be expensive.

Thermoplastic Polyolefin

In most cases, thermoplastic polyolefin, or TPO, is the cheapest roof material available. TPO is similar to both PVC and EPDM, but it is 100 percent recyclable. TPO is a lightweight membrane that is typically heat-welded at the seams rather than adhered like EPDM—however, it can also be mechanically fastened. This welding makes TPO more resistant to leaks than EPDM, but the material also has many disadvantages. TPO is prone to shrinking and cracking. The material is also not fire-resistant. 

Spray Polyurethane Foam

SPF is a plastic that is sprayed out as a foam that then solidifies and expands over a rooftop. This foam seals off gaps on the roof and is extremely insulated, helping owners save on energy bills. SPF is typically layered onto a roof underneath another roof coating. Applying SPF is a specialized skill, and not all roofing companies offer it. Applying and maintaining this material can be expensive.

Because this type of roof is difficult to repair and replace, Maxwell strongly recommends against having this type of roofing material installed. 

Asphalt

Asphalt is an older method for commercial roofs. The material is rolled out and pressed onto a roof deck. Asphalt roof systems are typically more expensive than PVC, EPDM, and TPO but are also more durable and long-lasting. They are very tough and puncture-resistant due to the multiple plies included in the system. This type of material is recommended for manufacturing plants or any roof that will have roof traffic or penetrations.
