Spray Foam Roofing

Spray foam roofing, as the name would suggest, is sprayed onto the roof and expands into the shape of the roof making it a cost-effective and versatile solution, especially for complex roofs.


  • Spray foam is very easy to install and can typically be applied with zero interruption to the daily function of the property.
  • Can be applied directly over the existing roof and expand to fit all shapes and types of roofs.
  • Spray foam is energy efficient, keeping cooling costs low by keeping summer heat out and holding the cold, Portage winters at bay.
  • Spray foam roofs are very low maintenance.
  • When appropriately applied, spray foam roofs are completely waterproof.


  • Improperly applied spray foam doesn’t work and can even damage the property – installers need to have high technical knowledge.
  • The weather conditions must be appropriate for spray foam installation which can be trickly with the volatile weather in Portage.
  • While generally low-maintenance, spray foam roofs should be inspected at least twice a year to ensure they haven’t been damaged.
  • Damaged spray foam can be finicky to repair.

Modified Bitumen Roofing

Modified bitumen roofing is an asphalt-based roofing system that is designed to withstand harsh exposure and environments.  It was created for low-slope and flat roof structures.


  • Modified bitumen roofing is tear resistant due to its reinforcement layers.
  • Modified bitumen roofing is extremely waterproof, preventing leaks even in the sometimes extreme weathers in Portage.
  • Adding a cool roof like solar reflection to the top layer of your modified bitumen roof can help it to be energy efficient.
  • Due to its flexibility, modified bitumen expands and contracts with temperature changes.
  • Repairs and maintenance are very easy.


  • Older modified bitumen roofing installation processes can be a fire hazard due to the need for heated installation.
  • Modified bitumen roofing can be fragile when disturbed and isn’t suitable for areas of high foot traffic.
  • The impact resistance of modified bitumen isn’t as high as other commercial roofing materials.
  • The life expectancy of modified bitumen roofing is somewhat short at 10-20 years.
  • EPDM is an energy efficient commercial roofing option that can help keep out heat in the summer and keep in heat in the winter.

EPDM Roofing

EPDM roofs have a thin, waterproof rubber membrane that’s both durable and easy to install.


  • EPDM roofing is extremely cost effective and less expensive than other commercial roofing options.
  • Made from 100% recyclable materials, EPDM roofs are very eco-friendly.
  • EPDM roofs are very fire resistant.
  • Properly installed and maintained EPDM roofs can last 20+ years.


  • While it’s an overall inexpensive roofing option, more technical EPDM installations can be costly depending on the specific choices you make.
  • Non-reinforced EPDM is prone to puncturing and shrinkage which can lower its lifespan.
  • EPDM roofs are somewhat unattractive.

TPO Roofing

TPO roofs are a single-ply membrane used to protect from leaks and is considered a green option due to its heat reflective properties.


  • TPO roofing is a very durable option for a low slope roof system with a strong resistance to tears and punctures.
  • Due to its water resistance, TPO is fungi resistant.
  • TPO comes in a variety of color options which can help with both UV resistance and aesthetic appeal.
  • TPO roofs have a high impact resistance rating making them perfect for areas like Portage that are prone to hail.
  • TPO roofs have an expected lifespan of 20-30 years, are easy to install, and are low maintenance.


  • Not all brands of TPO are created equal, and it’s a relatively new product having only been introduced in the last 30 years, so quality can be hit or miss.
  • The cost for a TPO roof in Portage is higher than that of other commercial roofing options, but its durability and lifespan make up for the higher price tag.
  • TPO isn’t inherently fire resistant, although it can have fire retardant added.
  • Repairs require special tools like a heat welder, so, typically, TPO roofs can only be repaired by a professional.
