ROOF COATING COMPARISON CHART
Roof Coating Comparison
Below you will find the technical specifications of ArmorGarage Roof Coatings versus popular water based and elastomeric roof coatings. The difference is plain to see. ArmorGarage Roof Shield is NOT an typical elastomeric and 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. Water based and silicones 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 Coating 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 one of 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. You will need substantially more product.
- Guarantee- Gaco does not guarantee their product unless installed by an authorized Gaco installer. Furthermore Gaco does not Guarantee results of application such as stopping leaks. Guarantee is 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.
- Tensile Strength- Very Low should not be walked on.
- Hardness- 50 rating is exponentially softer than Armor Roof's 60 rating. Armor Roof can be walked on whereas Gaco cannot be.
- Elongation: Very low, may be subject to cracking in extreme conditions.
- 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.
