Commerical flat roof

At Union Roofing, we have extensive experience in commercial roofing installation. Flat-roofed buildings are characterized by a clean, modern look. Moreover, this type of roof allows the development of future projects such as a terrace, a green roof or even the installation of solar panels. The use of an elastomeric membrane has several significant advantages, such as recognized efficiency, easy maintenance and a lifespan of 20 to 30 years.


The elastomeric membrane: a dependable choice

Since the 1970s, the elastomeric membrane has become a must in the field of construction for all types of so-called flat roofs (roofs with a slope under 3/12 or 1:4). This modified bitumen coating is created by fusing a base membrane with a granule coated cap sheet. These are UV resistant and can extend the life of a flat roof up to 30 years. This is an investment that is worth it!


Take care to make a good investment for your roof by choosing elastomeric membrane!

Whether for a flat roof or low slope roof, Union Roofing has the advanced expertise necessary to maintain and repair your roof while ensuring optimum durability in all seasons. To achieve this, elastomeric membrane is a must. Indeed, this great product outperforms traditional asphalt products hands down.


Long-term peace of mind

Known for its durability, the elastomeric membrane has many advantages:

  • Life span of 20 to 30 years
  • UV resistant
  • Easy to maintain
  • Light and durable
  • Uniform quality when installing
  • Excellent waterproofing properties
  • Recyclable
