Q. What type of surfaces will a
Armor Roof Coat adhere to? And is it ok for flat or pitched roofs?
A. Armor Roof Coatings will adhere to most any type surface such as metal, wood and wood composites, masonry, concrete, asphalt roofs, Modified, EPDM, PPO, APP, Hypalon and all built up roofs. We recommend that any wood or wood composite be sanded first to remove any Mil finish. Any large Joints in concrete or wood roofs should be sealed with our roof mastic and reinforcing roof mesh. Simply apply a thin layer of mastic and then embed the mesh and coat over with a second coat. Let it dry over night and then apply coating. For metal roofs coat all boltheads and head laps with roof patch.
Armor Roof Coat is suitable for any type of roof, flat or pitched and can even be applied onto vertical surfaces such as parapet walls.
Q. What surface preparation is needed? Is a Primer coat required?
A. All surfaces must be clean of any and all rust, dirt, grime, mold, mildew and any other foreign materials, use chlorine or bleach solution to kill and remove mold & mildew. A good washing with water hose and some TSP powder usually gets the job done quickly. Be careful if using a pressure washer since this can cause additional damage to older roofs especially granulated tar paper. You want to make sure you get all the loose granules off but you don't want to be knocking anymore of them off with a high pressure stream. Once cleaned the surface must be dry.
Then repair any damaged areas such as split seams, cracks or holes with our roof mastic product, you can insert roofing mesh into the patching for added strength in needed areas. Bubbles should be cut open and dries out then repaired with paintable roof tape then coated.
In sum you want to make sure all flashings, seams and roof penetrations are properly sealed then when you apply the coating it will be virtually impossible for water penetration. See the pictures on this page for an example of a
Properly Prepared Roof Surface
For Metal Roofs that are rusted all loose rust should be removed and any remaining rust should be coated with a Rust Inhibitor. If your roof is bare metal and is not rusted then no priming is needed. If your metal roof has a paint coating on it we recommend our Bonding Primer be used to ensure adhesion between the paint surface and our coating. Concrete and Wood Roofs should have all the joints and seams sealed with a combination of our Roof Mastic and Roofing Mesh. This will ensure a crack in the coating doesn't form at the seam over the years.
Armor Roof Coatings do not require a primer coat(see above exception), they are self priming and there are no chemicals to mix! It's a very easy product to apply for professional results.
Q. How long will Your roof coating last?
A. It is guaranteed for 12 years and with basic maintenance such as keeping roof drains clean and removing large debris from storms it routinely lasts 15-20 years! At which time you can in most cases simply apply one coat for 12 more years of guarantee! This is really a superb product.
Q. Why is your coating more expensive than other coatings?
A. Look at our specs compared to any other roof coating. As with most products you buy as the quality of the product goes up so does the cost to make it. Armor Roof Coat is stronger, more flexible, has a harder finish for higher abrasion resistance, provides a higher water and vapor barrier and is Energy Star rated by the EPA. Armor Roof Coat also has a Class A UL fire rating! Roof Coat may cost a few dollars more because it's made with the best material ingredients allowed by the EPA. There are many Elastomeric Roof Coatings but you should know the difference. Most elastomeric coatings are water or silicone based. These are the cheapest versions and are usually sold through Home Improvement Centers and such. Armor Roof Coating is a rubber copolymer epoxy based roof coating. This is the highest grade of roof coating made and the most expensive to manufacture. We also use more of the key ingredients and not less like other manufacturers do who water down their products in order to offer a low selling price. This results in coatings prone to failure, extra long cure times, higher application temperature requirements or coatings that actually just wash away or fail in a few short years.
Our roof coating will pay off in reduced energy costs and cost of ownership which is the cost of the material divided by the number of useful years the product lasts. We guarantee Armor Roof Coat for 12 Years while the other products that may save you a few dollars have little or no guarantee and the few that have similar guarantees to ours seldom last to the end of their guarantee period! Bottom line is you don't want a guarantee replacement, you want a roof coating that will last longer than the guarantee. Armor Roof routinely lasts 15 or more Years! So don't be fooled by lower first costs from other products, in the long run they are far more expensive.

Q. What's the operating temp range and what temp can it be applied to?
A. Armor Roof Coat has a temperature range of -40 to 300 degrees. It will remain pliable at these temperatures and will not run, crack or become brittle. It can be applied in ambient temperatures down to 40 degrees.
Q. What is the cure time and can it be used on roofs with ponding issues?
A. Cure time is 24-48 hours unlike other EPDM products that take up to 7 days to cure. Armor Roof Shield lets you get the job done in a short window of time. Ideally ponding areas should be repaired so that they are properly pitched. If that's not possible Armor Roof is resistant to ponding water. We recommend a thick layer of our roof mastic with embedded roof mesh be applied over ponding water areas. This will do two things, it provides extra protection and adds thickness to those low areas helping more water to drain off. But for any area holding significant water for more than 48 Hrs, a roof drain or additional sloping should be considered.
Q. How is it applied and do I have to hire a professional? Also what is the coverage?
A. It is easily applied with a roller. No experience is needed and is designed to be applied by first time users. Coverage is 100 sq ft/gal for the standard coating and two coats are required. Do not apply thicker than 100 sq ft/gal. Coverage of 17-25 sq ft/gal for the granulated coating. If using the granulated coating it is applied by trowel.
Armor Roof can also be sprayed on with the proper spray equipment. A sprayer with 3000 psi capacity, 3/8" I.D. hoses and tips from .027 to .031 with filters removed can be used for faster application over large areas. The granulated version should not be sprayed. It's installed with trowels.
Q. What is the difference between the standard coating and the coating with granules and when should I use each?
A. The Granulated coating is the same as the standard coating except that it has rubber granules embedded into it for extra wearability. Use the granulated version for roofs with heavy foot traffic, around HVAC equipment or on roof decks that will have tables, chairs and foot traffic. You can do the entire roof area first coat with the standard version and then apply a second coat of the granule version in areas with high wear concerns.
Q. What is your warranty on the product and policy.
A. Armor Roof is guaranteed for ten years from any material defects when properly applied and applied to a properly prepared surface. We will replace free of charge any amount of material that has been determined to be materially defective in any way. ArmorGarage is solely responsible for the replacement of product and shall not be liable for any incidental or consequential damages under any circumstances if such should occur. Armor Roof when properly applied to a properly prepared surface will yield 12-20 years of service.
Q. Can Armor Roof Coating be bought in different colors?
A. Yes. White and light gray are the standard colors and 13 additional special colors, please allow 5 extra business days delivery time for special colors.
Q. Do you have large quantity discounts and how long does it take to get?
