ROOF COATING COMPARISON CHART

Below you will find the technical specifications of Armor Roof Shield versus popular Elastomeric Roof Coatings. The difference is plain to see. Armor Roof Shield is NOT an Elastomeric is made to provide a much longer useful life span than lower cost low quality retail grade products.

These types of retail grade roof products utilize Water and or Silicone as the main component of their formulation which are much lower grade materials versus our Copolymer Epoxy Rubber based coating and always breakdown prematurely regardless of how exaggerated a guarantee maybe marketed. The trade off in the lower cost materials(especially water) is in lower performance in key categories as you can see in the chart below.

Almost no other roof coating company provides ASTM-Accelerated Weathering test verification meaning that any claims to longevity is just marketing hype. Armor Roof Shield passes the ASTM 9000 Hr accelerated Weathering test with no signs of degradation. Armor Roof is an industrial grade roof coating that can be applied by even first timers with professional, energy saving, leak stopping results that will last. Our roof coating will assure you the lowest cost of ownership(cost/years of useful life) over the long term.

NOTES:

^Gaco Notes - Coverage: On textured surfaces such as all asphalt base roofs Gaco will require 3-4 coats. Actual coverage on textured surfaces is 33 SF/Gal.
  • Tensile Strength- Very Low should not be walked on.
  • Elongation: Very low, may be subject to cracking in extreme conditions.
  • Guarantee- Does not Guarantee results of application such as stopping leaks, guarantee void if roof coating is walked on or strict maintenance not done. Also Gaco does not provide any ASTM Accelerated Weather Testing to verify Longevity. Guarantee is nontransferable.


  • Hardness: This is an indication of how much wear & tear resistance a coating has, the higher the rating the better. Armor Roof Coat is as tough as nails and has the highest hardness rating. It means it is far more resistant to wear than lower rated coatings. Some coatings void the warranty or require an inspection after you walk on your roof. Any roof coating with a Hardness rating of 50 or lower cannot be walked on without the risk of damage. We recommend using our Granule version around areas that are walked on more than a couple of times a week. Even if you don't walk on your roof you should be concerned about wear. Rain contains lots of particles that it pulls from the air that are very abrasive and corrosive and along with the Sun(UV rays) is what produces that faded worn out look in standard roofs and roof coatings. As you can see Rood Coat has the highest hardness rating, each 5 points in hardness is an exponential difference. Plus we are one of only a few that pass the ASTM 9000 HR Accelerated Weather testing. We strike a great balance between hardness, durability and flexibility making Roof Coat extremely versatile so that it will wear like iron while not cracking or splitting during extreme temperature and weather exposure.

    Tensile Strength & Elongation are critical factors as to how much Stress, Expansion and Contraction a coating can withstand before failing. Most other coatings are significantly below Armor Roof Coat. In areas with wide seasonal temperature swings most other coatings are very prone to failure. Ames rating is based on use of Polyester Contouring Roof Fabric(additional labor and material costs).

    Elongation: Based on ASTM D-412 test means how much can the coating stretch before cracking, at 500% we offer plenty of expansion capability with 99.999% memory retention! Flexibility is no good if the coating doesn't return to its original dimensions.

    Vapor Transmission or Permeability- Perhaps the most important factor of all, whereas the lower the rating the better the coating resists water and vapor transmission. Armor Roof Coat is four times less Permeable than Liquid Roof and multiple times better than the rest. Simply put, it means Armor Roof Coat is far superior at preventing water and moisture transmission through your roof! Some roof coatings have ratings that are barely below the threshold where moisture will penetrate them. With these coatings just a tiny bit of wear will cause them to start leaking. Black Jack 1000 is not approved for use on Flat Roofs.

    Application Temperature: An important factor to keep in mind, this is the temperature at which the coating stops curing and is vulnerable to rain and or not having the curing process restarting. The same holds true for the curing time, until the coating is fully cured it is vulnerable to being washed away. We receive many calls from customers who had other popular brands just washed right off their roofs.

    *Gaurantee-10 Yr only when applied by certified Lexis applicator.

    ~EPDM Coatings, Liquid Roof and Pro Guard are the same product and therefore have the same specifications.
