Waterproofing roof options are one of the ‘behind the scenes’ materials that do not get enough credit. Reports show that waterproofing accounts for 1% of a building’s construction costs. However, when ignored, it can be responsible for 90% of its damage! Waterproofing your roof protects the integrity of your roofing and building structures by preventing water damage when done by a professional like ABC Roofing.

There are a variety of waterproofing roof options. They are all designed to meet the waterproofing needs of our different roofing materials. It can be quite an overwhelming process so here are some of the most common waterproofing roof options and some of their properties:

It may be more pricey than other waterproofing options, but it will definitely keep your home protected for longer. Polyurethane can be extremely dangerous if not handled correctly which is why we recommend calling ABC Roofing for help.


Ethylene and propylene are combined to create an effective, synthetic rubber material known as EPDM. This material is popular for its water-repelling, flexibility, and recyclable properties. Available in different thicknesses, this material is an affordable way to ensure that your home is protected.

Rubberized Asphalt

Rubberized asphalt is a popular material for commercial roofing systems, for a number of reasons because it:

  • Is tough but flexible
  • Can withstand the harsh outdoor elements
  • Has a moisture vapor permeance that is very low

When used on concrete, this material can also help to cut down on cracking This means that it not only repels water but enhances the durability of the materials underneath it.


While thermoplastic is not the cheapest waterproofing material on the market, it does offer a number of benefits, such as:

  • It is one of the strongest waterproofing materials around
  • It can provide 50 years or more of durability
  • Containing elastomers allows it to resist impact better than other materials

Aside from the costs, unfortunately, thermoplastic is extremely tricky to work with, especially on a roof. Luckily, ABC roofing is just a phone call away!

Bituminous Membrane

Combining bitumen (asphalt/coal-tar) and organic liquids leave you with a very sticky and durable material popularly known as a bituminous membrane. This waterproofing material is perfect for protecting both commercial and residential buildings. This option may be slightly more affordable than other materials. However, it’s made of crude oil. This makes it an unsustainable product. Additionally, extreme temperatures and UV radiation shorten a bituminous roof’s lifespan.

PVC Membrane

A PVC membrane is a common waterproofing material made from polyvinylchloride. With a reinforcing base made from fiberglass or polyester mesh, this material has a number of benefits. It is:

  • Water-resistant and vapor permeable
  • Available as reinforced, making it more durable or unreinforced, making it more flexible
  • Easy to install
  • Has a long lifespan
