Frequently Asked Questions

Q: What makes the Acrylabs Roof System seamless?

A: The system is applied as a liquid with a separate fabric reinforcement embedded between coats. The cured membrane creates a durable, monolithic and watertight surface.

Q: Will my existing roof need to be removed?

A: The EPDM system should always be and is removed. That allows us to properly assess the condition of the substrate.

Q: What if my roof has been damaged by water or impact?

A: If long-standing leaks or an accident have damaged the structural materials, cutting open and repairing the plywood, metal or fibreglass materials may need to be performed prior to applying the new membrane.

Q: What happens to the equipment and penetrations now on the roof?

A: All supports, brackets and protrusions on the roof surface are treated with the Acrylabs system. This creates a positive seal to the flat areas and ensures that the entire roof membrane has no seams or joints.

Q: How are rain gutters at the edge of the roof addressed?

A: The Acrylabs reinforced system extends into to the gutters to seal the joint and fasteners. 

Q: Will the new roof membrane be heavy?

A: The completed membrane is very lightweight – only a few ounces per square foot.

Q: Will driving at high speeds affect the new roof membrane?

A: The Acrylabs System has excellent adhesion and has been tested to withstand high wind speeds. It has a long track record of outstanding performance on roofing in hurricane zones.

Q: What colours are available?

A: Light colours reflect sunlight and help keep the interior of RV’s and mobile homes cooler. Reflective White or Bone White are recommended but other colours are available to satisfy aesthetic needs.

Q: Will the process be expensive?

A: The application of an Acrylabs Roof Membrane is quite affordable and a fraction of the cost of competing inferior systems.

Q: Where is the work performed?

A: RV roof applications are performed at the facility of a manufacturer’s approved applicator or can be done on site. An Acrylabs crew will apply the system on-site for mobile homes and RV’s in parks.

Q: How long will the new roof membrane last?

A: The complete membrane is highly durable and is expected to last a minimum of ten years. It can be renewed after ten years (or anytime sooner) with the application of a single maintenance coat.

Q: Is the Acrylabs RV Roof System just another coating?

A: Acrylabs roof products are high performance materials originally created for commercial roofs in harsh environments. The composite membrane includes multiple applications of high strength coatings combined with fabric reinforcement.

Q: What about exposure to the sun?

A: Acrylabs components are UV resistant and experience minimal effects from exposure to sunshine, even in desert-like conditions.

Q: Will the membrane be flexible?

A: The membrane is designed to be highly flexible, a feature necessary for application to RV’s and mobile homes. The membrane accommodates expansion and contraction of metal and other roof materials as well as the flex and movement of RV’s travelling over rough roads.

Q: How will the membrane perform in very hot and very cold conditions?

A: The membrane will remain highly flexible under all weather conditions and climates. It is unaffected by extreme temperatures from- 50° C to +50° C and rapid changes between.

Q: Will this system work on other type of roofs?

A: Acrylabs Roof Systems are applied to a wide variety of commercial, institutional and industrial roofs. The system has been applied to millions of square feet of flat, low-slope and metal roofs, with great success. Most smooth surfaces are appropriate for an Acrylabs system which can be applied directly to existing roof materials as well as new plywood, hardboard, etc.

Q: How long has this system been in use?

A: Acrylabs has been manufacturing these roof systems since 1989.

Q: Can I buy the product myself?

A: No we do not sell the product.

Q: What about RV roof coatings I can buy at Home Depot and do myself?

A: Good question. Short answer is no. These coatings are known to last for at most a year in the MIDDLE of the trailer but needs re-application on all seams and corners after one year. Finally you will be required to condition your roof a couple times a year at a cost of about $100 per time.

This is actually one of my favorite questions to answer, because it gets into the science of coatings. This is our specialty.

In simple terms, a coating is simply a hardened liquid. Depending on the level to which a coating cures, it's density, elasticity, and tensile strength all effect its durability, longevity and performance.

When dealing with acrylic, rubber, or epoxy coatings for RV roofs, there are certain inherent weaknesses.

1) UV degradation: the sun is the most powerful degrader of coatings, and cannot be underestimated.

2) Natural erosion: wind, rain, and sun will combine to erode an average of .5 mil DFT (dry film thickness). Most coatings go on at 2 mil WFT (wet film thickness), which shrinks to roughly 1 mil thickness per coat.

3) Tensile strength and elasticity versus stresses and adhesion. It's an age old battle. 99% of coatings are corner to corner coatings, meaning they don't overlap and come down the side. This causes a couple of issues, particularly for RV's, trailers, and even mobile homes. These structures are constantly shifting, moving, expanding, and contracting. They simply cannot hold on, and will start to shrink, creeping away from the sides, which inevitably leads to delamination. Often you will see micro cracking, and in some cases even larger.

What this means, through all of these weaknesses, is that generally most coatings on these structures last not much longer than a year.

Q: Why do the dealers charge so much?

A: Our system is completely different than the dealers. It's a good question to ask them.

Q: What is dry rot?

A: Wood that had gotten wet and then dried out has been weakened and can no longer support as much weight.

Contrary to what most dealers will say, it does not always need to be replaced. RV roofs are not designed for load bearing or foot traffic to begin with. As long as you can ensure no water will get in again with our Acrylabs system then if not severe you may be able to avoid this.

Q: How long does it take?

A: Much depends on demand as we often have a waiting list but we ask that you expect a week.

Q: How long has SEI Chemical Canada been in business?

A: We have been doing specialized coatings in the area of anti graffiti, anti microbial, anti corrosion and building envelope since 2005.

Q: Are you insured?

A: We have sought out and attained specialized insurance that applies to RV roof systems specifically.

Q: Are there any discounts?

A: Yes we offer a 5% discount when you bring a friend. The discount applies to BOTH projects.
