Roofing.

​

Torch on roofing is made up of synthetic rubberized asphalt sheets (SBS Modified Bitumen) that can be installed using a variety of methods depending on building type, substrate, usage and budget. Commonly referred to as a two-ply torch-on roof. Two-ply systems utilize a slip sheet (on a combustible substrate), a torch-applied base sheet and a torch-applied layer with a factory-installed granular surface (cap sheet). These systems tend to last much longer than single-ply EPDM or TPO systems, which are applied in one layer of 40-80 mils thickness. A torch on the SBS system creates a more substantial, durable membrane ranging from 220 mils to 300 mils in thickness.  The multiple layers also significantly reduce the chance of workmanship error and increase the ability to withstand traffic and penetrations within the roofing membrane.

Torch-on-roofing systems do tend to carry a higher initial cost over single-ply roofing options; however, torch-on routinely outlasts and performs single-ply roofing alternatives, providing torch-on roofing with a long-term value not seen with other roofing systems. The durability, lifespan and versatility of the torch on roofing make it the definitive roofing system in Vancouver and the lower mainland.

Advantages of Torch on roofing systems

There are several advantages to having a multi-layer torch on roofing system installed. Some of the most common benefits seen when installing this type of roof include:

  • Torch on roofing is made of a synthetic rubberized asphalt material which provides exceptional flexibility regardless of temperature. Any property owner in need of strong yet flexible water resistant roofing material should go with this type of product.

  • Versatility can provide a superior roof system across a variety of substrates and building types

  •  Torch on roofs also reflect UV rays, which helps to keep indoor temperatures down during the summer months.

  • Low Maintenance torch on roofing requires very little annual maintenance.

  • The average lifespan for a three-layer torch on roof is two decades. Two-layer roofs tend to last around 15 years, and they rarely need to be repaired.

  • Modifications are easy, whether it’s a new skylight or a substantial addition

Rolls of the material can obtained and installed as required.​

  • Durability is key to the success of a torch on roofing system. The rubberized asphalt material provides a superior due to the tear and puncture resistant properties.

Rubberized asphalt waterproofing (Hot Rubber) is a monolithic, fully bonded roofing and waterproofing membrane commonly found in high-rise roofing, as well as parkade roof slab systems. The membrane is hot applied and then reinforced with a polyester fabric and protection board. Upon cooling the system can be built up in a variety of ways utilizing insulation, paving stones, Traditional ballast or vegetation. Rubberized asphalt remains to be the cornerstone of our waterproofing operations, due in part to the superior versatility and protection provided by hot rubber over other waterproofing systems.
