How to Successfully Apply a Roof Coating System on an Aged Roof

When it comes time for roof maintenance, one option you have is applying a roof coating system. It can be a great way to extend the roof life and keep it in good condition for years to come. However, there are a few things you need to know before you get started. This blog post will go over the standards for successfully applying a roof coating system on an aged roof. Let’s get started!

Preparing Your Roof Surface Is Important

Administrators must identify any current roof problems before embarking on a roof-restoration operation. Before the paint treatment can commence, you must repair exposed seams, blisters, cracks, and other flaws.

Wet insulation may be located using infrared technology, which is crucial. After removing the wet insulation and installing the replacement membrane, professionals may start surface preparation and coating treatment.

Before adding any roof coating, it is necessary to prepare the roof surface properly, and the level of preparedness required varies depending on the roof’s present state. Fixing, priming, and sweeping seams could be all that is needed for preparation so you can properly apply your roof coating.

Adhesion can not happen unless the surface to be coated is dry. If the roof coating chosen does not attach adequately to the surface, it may gradually disband from the surface, leading to a failed project.

As with most surfaces, a primer is advised. Professionals must spray the base coat at the company’s suggested film thickness in multi-coat installations. Workers must spray the topcoat parallel to the base coat to avoid inconsistencies formed by roller markings.

What Is an Elastomeric Roof Coating?

An elastomeric roof coating is a fluid coating usually made of acrylic or silicone, which hardens to form a long-lasting, extremely elastic membrane. Its elastic properties make it simple to install with most roof surfaces, and highly adaptive to various weather situations.

Elastomeric roof coatings are applied to roofs to offer an extra layer of weatherproofing, or to prevent and stop leaks, enhance the roof’s integrity, and prolong the roof’s lifespan, saving you money.

What Types of Surfaces Can Elastomeric Coatings Be Used On?

Numerous roofing types, including but not limited to the following, can be effectively coated with elastomeric roof coatings:

  • Asphalt
  • APP or SBS cap sheet
  • Aged EPDM or TPO membranes
  • Built-up roofing
  • Concrete
  • Exterior-grade plywood
  • Existing elastomeric coatings
  • Fiberglass
  • Metal
  • PVC
  • Sprayed polyurethane foam

What Are the Benefits of Applying Roof Coatings?

There are many benefits of roof coatings, including. 

  • UV protection and lower energy costs due to energy efficiency. Silicone roof coating systems provide a “cool roof” impact in the summertime, lowering electricity bills.
  • It gives extra corrosion and waterproofing resistance. Silicone roof coating systems offer a durable barrier from snow, rain, ice, and other elements. It also provides additional support for roofs that may be subjected to strong winds.
  • Extend roof life and delay roof replacement.
  • When installed, it’s simple to fix and upkeep. It can be resealed by adding an extra coating to damaged regions.
  • Roof viability is restored, and the roof’s lifespan is extended. An elastomeric coating properly applied might last 10-20 years.

Elastomeric Coatings: How to Use Them

Step 1: Collect the necessary equipment and tools.

Installations will be faster and easier if you have the correct equipment and materials. For the application procedure, you’ll need all-purpose brushes, solid plastic core roller covers, mallets, scissors, a power drill with mixer, push brooms, and sprayer equipment, in addition to personal protective gear, including goggles, gloves, work boots, hard hats, and safety harnesses.

Step 2: Clean the roof with a high-pressure washer.

To apply a coating successfully, you must first prepare the surface. Before spraying the coating, the roof must be neat, clean, and dry. Clean the roof of all debris and grime. Then, using a broom or brush, loosen the dirt in badly stained areas. Before proceeding to the following step, make sure the roof is dry.

Step 3: Reinforce and repair the roof.

Before spraying the elastomeric roof coating, you must repair any damage. Then, reinforce these restored sections and roof penetrations, curbs, and rooftop apparatus using Polyglass PolyBrite polyester fabric and mastic.

Step 4: Perform an adhesive test in the field.

The next step is to perform a field adhesion trial on the roof to identify what primer (if any) is required. Put the primer, spread the fabric, and spray an additional coat of primer over it to connect a test sample of polyester reinforcing fabric, keeping two inches of material free for the trial. Wait 24 hours for the fabric to dry before pulling it with the uncoated part. You will require a primer if the coating breaks cleanly off the substrate; however, you may not require a primer if the primer is left on the surface.

Step 5: Combine and stage roofing materials.

To ensure optimal administration, properly mix all Polyglass materials, such as the elastomeric roof coating. Blend the substance using a 3/4-inch corded electric drill with a power mixer attachment. All items should be kept out of direct sunlight and protected from chilling.

Step 6: Set up spray equipment and start spraying.

Spray the coating equally at the desired wet film thickness while maintaining the nozzle 12-18 inches from the surface using airless spray gear with a minimum capacity of 3/4 gallons of volume per minute and 3,300 p.s.i.
