Best Commercial Roof Coating For Flat Or Pitched Asphalt & Rubber Based Roofs
Free Shipping Direct To Your Location!

With the lowest moisture transmission rating Armor Roof Shield is the best roof coating at keeping water out of your building. The only thing more water tight would be a pool liner! It also has superior adhesion(cannot be separated from roof material), elongation (500%), memory retention (99.9%) and abrasion ratings (Shore D Hardness-60). This is an often overlooked factor/mistake made by customers who unknowingly purchase roof coatings based solely on price or name recognition without comparing or even looking at the product specifications. Many companies publish little or no specifications due to poor test results. So simply buying a product off the shelf or from some mass retailer with no knowledge of the performance specifications is not the right approach for doing a commercial roof job.

At ArmorGarage we feel who you buy from is as important as what you buy and it's why all our Sales Reps have extensive field experience with all the products we sell. We can guide you or your applicator every step of the way so that your project is done right the first time. As opposed to buying roof coatings from someone who never stepped foot on a roof.

WHY ARMORGARAGE ROOF COATINGS HAVE SUPERIOR LEAK STOPPING & LEAK PREVENTION CAPABILITIES

Vapor Transmission rating or Permeability of a roof coating is what determines how much moisture can pass through the coating over a period of time. As your roof or roof coating ages it becomes more permeable which simply means that the molecular bonds start to weaken and the pores of the coating get larger due to stretching and UV aging, eventually water starts to actually pass through your roofing material or coating.

That's why sometimes you can't seem to stop the leaks no matter how many flashings, small cracks or pits you patch. It's because the water may be slowly passing through the pores of your roofing material or coating over a large area and then running to the first opening. In which case finding and patching the leaks becomes a costly and futile effort. The majority of roofs start leaking due to this issue, in other words they just simply stretch and wear out from UV exposure and the elements.

So you want to start out with a coating that has the lowest permeability rating (moisture transmission) and highest rubber content as you can so that as the coating ages and the pores start to open up from UV degradation and stretching it will still repel water. If you start out with a high permeability rating and a low or no rubber content it only takes a surprisingly small amount of aging and stretching till that coating fails. Also the type of rubber is very important, we use Butyl rubber which is the highest grade of rubber for coatings.

ARMORGARAGE GUARANTEE

Armor Roof Shield has by far the lowest Vapor Transmission rating and when test during the ASTM G53-9000 HOUR Accelerated Weather Test which subjects the coating to extreme UV exposure and temperature swings, it showed no degradation or loss in permeability! It's why we offer a 15 year guarantee and no one else can and doesn't! Some other brands offer much longer guarantees but actually state that they do not guarantee results or you can't walk on your roof or your warranty is void if not installed by professional and here's the best part, you have to renew your guarantee every 10 years! Guess what that means, it's going to cost you every 10 years or have no guarantee. What kind of guarantee is that? If you cover your entire roof with Armor Roof Shield it's guaranteed 15 years with no ifs, ands or buts to keep you leak free! It flows into every tiny crack, crevice and pin hole and forms an impenetrable barrier that is super durable and impossible for water to pass through. 

THE ARMORGARAGE DIFFERENCE

When we say Armor Roof Shield is the toughest roof coating there is we mean it! This is the Light Gray Armor Roof Shield in our extreme performance test.
Don't try this with your water based elastomeric or silicone coating. The force and abrasion would rip regular roof coatings to shreds.

This is an arial view of our Metal Roof Coating installed at the Security Building at Beale Air Force Base. It's the same coating as this but modified to compensate for the extreme expansion and contractions of metal roofs. There's a reason the Air Force has chosen ArmorGarage for their roofs! You will get the same results and performance for our Tar & Rubber Roof Coating.

Below is a testimonial from our customer Patricia Jarimillo that shows how tough our roof coating really is. In addition to Patricia there's a testimonial from one of our residential  metal roof customers that lives in an historic neighborhood that had over 80% of the roofs destroyed by a severe hail storm while his roof suffered only minor cosmetic damage. Between our severe weather testing and the real world hail storm testimonials we're not sure what else we can say.

                                                                                                         "Hi Jim,
Here is our review of ArmorGarage Flat Roof Coating. It's great! This review comes a year after we used your product on our roof so it's more a testament to the quality of your product then merely getting the job done. We've had several heavy hail storms and rains and of course, we had to go up and check out the roof. There were no dents, no peeling or lifting of the product, no pooling and no bubbling or stretching. It looked perfect. My husband says, "That stuff really works." As stated, the Flat Roof coating bonds to the roof and is not merely a latex coating that will eventually peel when water gets under it from a crack, dent or hole produced from hail. It doesn't peel off gloves or boots either. We also noticed right away that the solar coating aspect of the product helped to cool the interior by at least 10-15 degrees. Great product. Our roof size required 22 buckets which we consider an investment. Thanks, Patricia - Hillsboro, NM."

Here's a comment placed in our comment box on the checkout page from a customer who was reordering more roof coating to do the rest of his rubber roofed trailers. Comments: "Your product is beyond belief. You should see what it accomplished on my rubber roofed trailers, just incredible." Scott from Tacoma WA. Scott has promised to send us some pictures. We'll post them as soon as we get them.
 
IF YOU HAVE A LOT OF FOOT TRAFFIC ON YOUR ROOF

Available with embedded rubber granules version for roofs that have areas that are walked on regularly such as roof decks or areas around roof mounted mechanical equipment. Rubber Granule Version is applied with trowel if using roller thin slightly with Xylene. If doing walkways or areas around roof mounted equipment, a base coat of standard coating can be applied first and then second coat with granule version on high wear areas is acceptable.

Custom Colors available on orders of 50 gallons or more.

For projects 10,000 SF or more please submit a Request For Quote form for a quick discounted price.

Once you have applied two coats of Armor Roof Coating you will have 15 years of guaranteed leak free service from your roof! Proper repairs to all flashings or other defects in roof with ArmorGarage Roof Mastic is required prior to application of coating. Coating must be applied to entire roof for warranty coverage. Once a year routine inspection/maintenance is recommended to remove any accumulated debris and to ensure roof drains are clear.

Guarantee shall consist of coverage for delamination or erosion of the coating during the warranty period, coating must be applied to entire roof surface, there is no guarantee for partial roof coverage. This is a tried and true product that doesn't fail and each lot is thoroughly test before shipping to ensure a defect free product but should you feel that the product has failed for any reason we request that the property owner notify ArmorGarage by email or fax with a description and nature of failure. On substantiation of a product defect, ArmorGarage, as its sole liability and the property owners exclusive remedy, will provide sufficient replacement product to repair all affected areas. ArmorGarage is not liable for any labor or consequential damage costs such as but not limited to mold or mildew damage, loss of use or any damage to property.

Exclusions to warranty: Damage arising out of failure to apply coating in accordance with our instructions, natural disasters and acts of God or nature, shifting or swelling of the roofing system or structure, exposure to destructive chemicals, over accumulation of organic materials, water or other roof debris, failure of previously applied coating(s), acts and causes beyond our control, negligence, misuse of the product, and cosmetic changes in coating appearance. Failure of product due to ponding water areas that lasts longer than 48 hours after last rainfall. For these areas use our Roof Ponding Water Coating.

Because there are extenuating factors beyond our control it is the purchaser's responsibility to repair all roof defects properly such as peeling prior roof coatings or patching materials, delaminating or damaged seams, flashings, mold, mildew or badly deteriorated roofing material prior to application of our roof coatings, to apply product at recommended thickness to a listed compatible surface during proper weather conditions.

Coverge is 100 sf/gal and two coats are required. To determine number of 5 gallon pails required divide the square footage of your roof by 250 this will result in the number of pails to do two coats. To determine the number of 50 gallon drooms divide the square footage by 2500 this will result in the number of drums required to apply two coats.

 

The following series of images perfectly illustrates how to do a proper commercial roof coating job. Even though these smaller roofs the concept is exactly the same no matter how large the roof is. Clean the roof, mastic seams and flashings as need and roll or spray on two coats. 

Please take note of the roof to the right it has an Aluminum Fibered Roof Coating on it that is failing after only 3 years. That is the reason the owner chose Roof Shield for this other leaky roof and all the remaining roofs.

 

This is a close up of the an area patched with residential grade roof cement or coating. This is typically what happens after just  a short time. You must remove as much as possible and then coat over whatever can't be removed with our roof mastic as seen below.

This is the roof prepared with our roof mastic. The owner chose to do all the seams and flashings since  the roof was small enough. Normally you would apply our roof mastic to where it's needed only. But this isa good example of prepping any roof. Once the coating was on it was impossible for it to leak and it didn't

This is the finished roof after two coats. The roof is now close to 20 years old and the owner has not had to recoat it. When the time comes all that's needed is a cleaning and roll on one new coat.

APPLICATION:

Product is applicable down to 40 degrees. Temperature must remain above 40 degrees for a minimum of 24 hours after application. Do not let freeze.

SURFACE PREP: Roof must be cleaned of all dirt, debris and residues, scrub any mold or mildewed areas with chlorine or bleach solution. Power wash if possible. Patch any damaged areas, visible cracks, punctures or areas that have completely worn through, use our Roof Patch Mastic for best results. Visually inspect all roof flashings, seams for debonding, all penetrations and repair as needed. Only seams that have split apart or cracked need to be patched, same with curb flashings, only flashings that have cracks or pit holes need to be patched. Embed roof mesh into Roof Patching Mastic for extra strength and flexibility. All ponding areas should be coated with two coats of Roof Mastic, embed layer of roofing mesh in first coat and then apply second coat. Let the mastic dry and then coat with Armor Roof Shield. Any ponding areas that hold water more than 48 hours should be coated with our Ponding Water Roof Coating. Armor Roof Coat is very forgiving as it will cover up many types of small mistakes but a little extra time and effort in prepping your roof will result in a much higher quality job.

 

APPLICATION: Roof Coat is easily applied by just about anyone and requires no special skills or experience. The main objective is to get an even coating over the WHOLE roof. If you do that, Roof Shield will take care of the rest.

 

On Large roofs after it has been cleaned and prepped mark out 500 square foot sections as shown in the image below and place a pail in each section. Mix the coating in can with paddle mixer on low speed. Use a high quality brush to coat any hard to reach areas first. This method makes it easy and foolproof to get the coating applied evenly at the proper spread rate. Simply roll or spray one pail per square!

If rolling you can use a calibrated squeegee to spread the coating out, it makes it esier cause the coating is so thick a roller sometimes slides across the top at first. Then backroll with your roller.

Then proceed to next section and repeat until entire roof is coated in the same manner maintaining the 100 SF/Gal spread rate. Roof Shield can be applied from roof right up parapet walls. Allow first coat to dry(24-48hrs)until dry and hard to the touch then apply second coat. For best results apply second coat perpendicular to first coat. If need be you can wait several days or a week or two between coats, the second coat will reactivate the first coat and the two coats will bond and cure into a single monolithic rubber surface. Be sure to cover every inch of roof surface. As long as you get the coating on 100% of the roof surface there is no possible way water can leak through. Tip: Make sure you check the inside of all mechanical equipment and the flashings around all roof penetrations, often water penetrates the inside of roof mounted equipment and other flashings, finds its way down to the roof deck and runs to an opening which could be far away from the original leak source.

 

Armor Roof Shield cannot be sprayed with light duty sprayers designed for water based products. Use a Commercial Airless Sprayer with 3300 psi, .75-1 gpm minimum with a .027- .031 tip with 3/8" ID hoses. For hose lengths greater than 60' use 1/2" ID hoses. Graco models-Ultra Max 795 or higher. Depending on sprayer thinning with 4-8ozs Xylene per 5 gallons may be needed for proper spray pattern. Maintain the 100 sq ft/gallon spread rate.

Application for rubber granule version is by trowel with average coverage approximately 25 sq ft/gallon. A base coat of the standard coating topped with one coat of the granule version on walkways or around mechanical equipment is acceptable. A test patch should always be done first when applying to any type of rubber roof to ensure compatibility.

Do not apply if rain is forecasted within 24-36 hrs

Roof Coating Comparison
Below you will find the technical specifications of Armor Roof Shield versus popular water based and elastomeric roof coatings. The difference is plain to see. Armor Roof Shield is NOT an 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 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.

The following is an explanation of the data you saw in the comparison chart regarding Harness, Tensile Strength and Elongation. It's important that you understand what these numbers mean so you know what level of performance you will be getting. Not knowing these numbers is really buying blind. If you need help in understanding all this data please feel free to give us a call or send us an email. 

 

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 weather conditions.

 

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 tells you how much can the coating stretch before cracking, at 500% we offer plenty of expansion capability and with 99.999% memory retention! Flexibility is no good if the coating doesn't return to its original dimensions. Most coatings will stop returning to their original dimensions after a relatively low amount of expansions and contractions! Then they start leaking because their pores have been stretched past the water repelling point. Then when you look for the source of the leak you will never find it because the the roof is leaky right through the microscopic pores of your bargain roof coating.

Tensile Strength: We have found through extensive testing that 1000psi of tensile strength is needed for a coating to both perform at it's optimum and to be able to survive the high stress demands encountered on roofs. If a coating isn't strong enough it will simply break down and cease to perform. It's that simple.

 

With commercial roof coatings the saying you get what you pay for is very appropriate. Bargain priced coatings have only one superior feature they offer you cost savings albeit for only a short time until you have to redo your roof cause it's leaking again.
