Benefits of Heat Welded Seams


How Heat Welded Seams Can Strengthen Your Roof 

Your building’s roof keeps out heat and cold and protects your business against inclement weather.  It works to defend your facility against leaks and moisture infiltration. While there are many types of roofing to choose from, some roofs do not prove as long-lasting as promised, and may need to be repaired or replaced within a few short years. Many times, it is the roofing attachment method that can ensure longevity.  One of the most popular attachment methods is mechanical attachment with heat welded seams.  Here are just a few of the ways that heat welded seams can keep your roof strong and solid for many years.


Moisture infiltration is one of the most serious and insidious threats facing modern structures. If rain is allowed to enter your building, it may cause structural damage and contribute to the growth of mildew or black mold. This is why it is so important to have a roof that completely keeps out the water.

Heat welding can help provide you with the dependable roof your building needs. This process produces results six times stronger than most adhesives. With heat welding, your roof’s seams will be even stronger than the durable roofing membrane around them.


Heat welded seams are not subject to significant deterioration over time. Your new or replaced roof will effectively resist the rigors of:

  • Cold
  • Heat
  • Rain
  • Severe weather
  • UV rays

This level of resistance can ensure the durability and longevity of your roof.

Energy Efficiency

Single-ply roofing membranes like PVC and TPO that use heat- welded seams are known for their Energy Star ratings due to UV reflection.  In addition to this energy savings, the nearly impermeable nature of heat welded seams helps to keep water out of the building.  Coupled with long-term durability, this energy efficiency makes a heat welded roof a smart and cost-effective solution for your building.

Easy Repairs

Heat welding works as well for repairs as it does for initial installation. You will find your roof incredibly resistant even to high winds and severe weather, but damage does sometimes occur. Heat welding can often provide a simple, effective and inexpensive solution to the problem.

Keeping Your Roof Sound

Your roof plays a large role in your building’s integrity and ability to resist the elements. Heat welded seams could prove to be one important tool in your quest to keep your building safe, dry and efficient.
