ProShield Polyurethane Roofing
Don’t Replace your roof! Restore with a system that is even better than a brand new roof
Save the time and hassle of a full tear-off by having us install the ProShield dual membrane system on your roof today! What you end up with is a thicker, tougher, longlasting roofing system while also saving you up to 50% on cost of replacement.
ProShield is a roof restoration system that in reality is a standalone 110 – 120mil DFT roof membrane. While products such as Acrylics or Silicones are just roof coating systems, these coating systems are usually a 15 – 30mil DFT for Acrylics and 22 – 25mil DFT for Silicone. Our Urethane top coat is tougher and has better chemical resistance as well.
Protect your investment & extend the life span of your roof
Typically flat/low slope commercial roofs will have areas of ponding or standing water. Ponding is defined as water that remains for 48 hours or longer. Ponding water accelerates the deterioration of many materials, including seam adhesive in single ply roof systems and asphalt roofing material. Ponding water is an exclusion in most conventional roof manufacturers (EDPM, TPO, Bitumen sheet, etc.) and is a condition that can void their warranties.
Ponding water is NOT an exclusion in our warranty!
Materials
ProShield Emulsion is a water based single component cold spray applied coating that combines the elastic properties of polymers with the weatherproofing and waterproofing capabilities of highly refined asphalt. This ZERO VOC high-build coating forms a seamless waterproof membrane that fully adheres to most construction substrates. This is very important in restoring the waterproofing capabilities of the existing roof. It also displays excellent chemical and corrosion resistant properties.
ProShield Emulsion is designed to provide a durable elastomeric protective coating and can be used wherever an impenetrable moisture barrier is required. ProShield HE can be used by itself as a complete protective coating membrane or be used in combination with ProShield Coating Technology Inc. topcoats and fabrics to form a fully redundant and lifetime renewable roof system. Unlike other fluid applied materials we do not compromise, we incorporate reinforcement fabric in all of our specifications. Think of it like steel reinforcing rod in concrete, you’re stronger for using it.
ProShield Coating Technologies utilises two formulations to meet specific project requirements. Both ProShield emulsions are blended to meet the CAN-CGSB- 37.58 standard and are the primary (base) waterproofing component of our UL Class A and Factory Mutual 4470 Class 1 roofing systems. Most of our systems also can be LEED USGBC (Green Building Council) Certified.
Our fabric is a 90GSM (2.7 ounce) stitch-bonded heat-set polyester high-performance reinforcement fabric designed for water-based emulsion coatings, cold-applied built-up roofing and elastomeric roof coatings used in *MESH REINFORCED ELASTOMERIC ROOF COATINGS (MREC) SYSTEMS.
These fabrics are designed to be used with liquid roof coatings to create a solid reinforcement layer, the fabric has high absorption capability, allowing liquid coating materials to quickly wet into and become encapsulated, forming tough waterproof details and reinforcements.
MREC systems are accepted by the US Department of Defense; one of the toughest standards to meet. Referenced in the Unified Facilities Criteria – Roofing Update January 1, 2017 here is the excerpt:
MESH REINFORCED ELASTOMERIC ROOF COATINGS (MREC).
6-3.1 Mesh reinforced elastomeric roof coatings can be used in two general ways:
- Mesh Reinforced Elastomeric Roof Coating (MREC): The application of a liquid applied elastomeric coating to an existing roof in order to sustain the roof at low cost.
- Mesh Reinforced Elastomeric Roof: The application of a liquid applied elastomeric coating to an existing substrate such as concrete or mechanically fastened over-layment.
For either application, the minimum dry film thickness is 40 mils (1 mm) applied in stages over 100% polyester fabric reinforcing.
6-3.2 MREC has a wide range of use in reroofing, repair, and sustainment. As indicated in Table 6-1, MREC may be used over most roof systems such as built up, metal, and modified bitumen. These coatings provide not only waterproofing, but can achieve cool roof ratings as well. At a fraction of the cost of replacing, MREC offers a high return on investment with low risk.
6-3.3 Elastomeric coatings may provide an inexpensive alternative to metal roof removal and replacement.
*Note. ProShield exceeds the US Department of Defence minimum DFT by over 150%.
There are several options available when considering a topcoat; Acrylics, Silicones and Polyurethanes. Why did ProShield choose Urethane even though it is the more expensive option? Simple answer – it is the best option for our climate and environment and we will not compromise – just a case of you get what you pay for. ProShield Urethane HE provides an authentic “cure” that provides a strong, resilient, chemical resistant waterproof surface.
ProShield Urethane HE is a high solid, single component moisture cure elastomer, designed for use as a cure in place, breathable, coating for our roof coating and foundation waterproofing system. ProShield Urethane HE provides extreme chemical resistance that far exceeds any other roofing material, resists weathering and oxidation and will withstand high temperatures and UV radiation.
How tough is our Urethane HE? We use this polyurethane in our traffic deck membrane system that is designed to take the punishment and chemical assault of vehicular traffic.
