Tri-Thermal Roofing and SPF: Is There a Difference?

Both Tri-Thermal roofing and spray polyurethane foam roofs have become household names for building roof solutions. Here’s an analysis on how they measure up with each other.

Tri-Thermal Roofing

The Tri-Thermal roof is a low-slope roof that uses three different materials to provide an energy-efficient roof system. It works similar to tar and gravel roofs, but uses multiple layers that include bitumen, reflective coating, and durability enhancements. In addition, Tri-Thermal roofing systems do not have a noxious smell and completes faster than its traditional counterpart.

The three layers of a Tri-Thermal roof are:

  • The base layer is a bitumen membrane that is sealed to prevent leaks.
  • The middle layer is a reflective white metal or bronze coating that reflects heat back into the sun. This layer also protects the roof from fire and weather.
  • The top layer is a dark color for foot protection and aesthetic purposes.

Advantages

Fire Resistance

Tri-Thermal roofing has excellent fire resistance because of its multiple layers. of insulation

Thermal and Sound Insulation

Tri-Thermal roofing’s layers of insulation absorb sound, decreasing noise levels for occupants, keeping temperatures inside the home more stable.

Affordable

Tri-Thermal roof installation labor is more affordable because it’s quicker to install than tar and gravel roofs. It requires less chemicals and equipment to install on roofing materials.

SPF

Spray foam is sprayed onto the roof, where it expands and hardens, forming a waterproof membrane. It is then covered with a layer of granules which are lightweight and able to reflect sunlight. The granules also serve as insulation. The foam also protects the roof from heat and damage, with the foam able to quickly shed water to prevent leaks. in addition foam also makes it easier for the roof to breathe and prevents condensation buildup.

There are two different types of SPF material:

  • Open-cell: These foam roofs are constructed with a foam core and a thin skin layer. The foam is applied to the roof surface and then sprayed with a polyurethane coating. It’s most efficient uses are often drywall and attic layers that provide insulation, strength, and lightweight insulation.
  • Closed-cell: Closed-cell spray are used to insulate buildings and other structures. They are sprayed on the roof of a building to increase the amount of thermal mass, deflect heat and light into the interior space, increase energy efficiency, and provide a more comfortable working environment.

Advantages

Quick Installation

Professional SPF applicators only need 3-5 days to spray an entire SPF roof during spring and early summer.

Easy Maintenance

SPF can start chipping away at its layers between 3-5 years after installation. With regular maintenance, SPF teams can reapply sealing caulk on potholes and other impact points on the material.

Easy Reinstallation

Most SPF roofs last for 20-25 years. Fortunately, it’s easy to tear off and replace SPF roofs than traditional single-ply materials or Tri-Thermal roofing systems.

Which One Is Best To Use For Your building?

The most important thing about roofing installations is performing it with the least amount of disruption possible while achieving exceptional performance.

Tri-Thermal roofing is an excellent choice because roofers can achieve quick installations and no noxious fumes. However, Tri-Thermal roofing requires some time to cure and test to make sure the new roof is efficiently working.

On the other hand, SPF roofing is easy to install as Tri-Thermal roofs and they can expand with the same density. However, SPF roofing takes 48-72 hours to fully cure.
