Renewing and restoring your existing roof provides a sustainable solution to your roofing issues without ever needing to tear-off and replace your roof again. Reusing your current rooftop saves a tremendous amount of money by avoiding landfill fees, transportation fees, installation costs, new roofing material expenses and business closure costs.

Restoring your existing roof is done directly over your current rooftop with no drilling, nailing, or seam-welding, and with industry leading roof coating products that contain minimal or zero VOC’s and no harmful or harsh odors. Your business is able to remain open during the restoration process with minimal disruptions to your businesses daily work environment. National Coatings has restored several buildings that require their businesses to remain open without business interferences, including hospitals, schools, medical centers, airports and more.

Restoring your roof with a full system AcryPly Roof Restoration System or AcryShield SPF Roofing System allows you to qualify for a 10, 15 or 20-year warranty. (Click here to request more information on our warranties.)

Renewing or restoring your roof is the economical choice versus traditional roof tear-off and replacement. These maintenance and restoration systems are cost effective and can be renewed every 10 or so years to avoid a roof replacement indefinitely.

Roof coating are excellent as maintenance systems because they renew and repair aged roof substrates while lengthening the roofs’ lifespan and lowering costs.

Maintenance Systems using Roof Coatings

The AcryShield® Roof Management (ARM) System is excellent for maintaining your roof. These systems allow you to renew your roof every 10+ years to avoid a costly tear-off indefinitely. The ARM systems provide a simple solution to lengthening your roofs lifespan while increasing or adding UV protection. This not only protects your roof from premature aging and roof failures, but it also lowers cooling costs associated with using an air conditioning unit to cool the inside of the building.

The ARM system uses localized polyester fabric reinforcement in weak areas on the rooftop to create durability and strength in those troubled areas. The base coat renews the roofs waterproofing capabilities and provides resistance to ponded water. The AcryShield topcoats used in these roof maintenance systems provide industry leading UV protection, longevity and brightness leaving you with a white, reflective rooftop with lowered roof maintenance costs, lowered energy costs and superior waterproofing capabilities.

The ARM systems are great for renewing your existing roof when minimal aging has occurred or for adding UV protection and high reflectivity to your existing, non-reflective roof – new or aged. These roof maintenance systems can be applied over asphalt, BUR, concrete, EPDM, Hypalon, metal, mod bit, PVC, single-plies, SPF (re-coat) and TPO roof surfaces.

Roof maintenance systems provide protection, durability and a lengthened lifespan. When your roof begins experiencing water infiltration, or aging and deterioration issues, a roof maintenance system can be installed to preserve and enhance your current rooftop. Reusing your existing roof and coating it with a roof coating system, allows you to remain open for business during the restoration process and you avoid a costly and timely traditional roof tear-off.

The AcryShield Roof Management (ARM) System is specifically designed for roof maintenance. It is a seamless, monolithic membrane that provides excellent weatherproofing and strength. This system also adds and/or boosts reflectivity to provide the maximum UV blocking protection against the main cause of roof leaks and failures - the sun’s harmful UV rays.

Apply the ARM System in few simple steps: 

Preparation

1. Make sure the rooftop is completely clean and free of any debris that would prevent proper adhesion. (Read: A Simple Test to Determine if your Asphalt Coating will Adhere – this can be applied to any roofing substrate)
2. Seal all joints, roof penetrations, leaks, etc… with AcryFlex and add reinforcing polyester fabric or butyl seam tape where necessary.
3. If there are areas where water accumulation is an issue, a custom localized reinforcement may be applied. In this case, apply an AcryShield base coat at the rate of 2 gallons per 100 square feet, approximately 46 inches wide. Immediately embed 40-inch wide polyester reinforcing fabric into the wet base coat, and then with a second coat of AcryShield basecoat, cover the fabric at a rate of 1 gallon per 100 square feet. Allow coating to dry (typically 8-24 hours depending on weather conditions) before proceeding to application of the remainder of the roof coating system.

Application

1. Spray, brush or roll the entire roof surface evenly with an AcryShield base coat consisting of 1.5 gallons per 100 square feet. Wait for base coat to dry - typically 8-24 hours.
   
   
   • These AcryShield base coats provide excellent waterproofing, superior adhesion, resistance to ponded water, bleed through protection and resistance to plasticizer migration.
     
     
2. Spray, brush or roll the entire roof surface in a crosshatch technique with an AcryShield topcoat consisting of 1.5 gallons per 100 square feet. Allow coating to dry completely before exposing the rooftop to any foot traffic.
   
   
   • The AcryShield top coats provide industry leading UV protection, longevity and brightness. These roof coatings are formulated for superior dirt pick-up resistance and protection against biological attack, such as algae and mold.
