Does Rubber Roof Coating Stop Leaks? Your Ultimate Guide

Do Rubber Roof Coatings Stop Leaks? Yes — Here's How
Why ArmorGarage's industrial-grade rubber epoxy coatings outperform every patch, seal, and silicone on the market
Maintaining the integrity of your roof is one of the most critical aspects of protecting your home, commercial property, or RV. Leaks cause extensive damage and lead to costly repairs if left unaddressed. This is where rubber roof coatings come in — but can a coating truly provide a long-lasting solution to water infiltration?
The short answer: yes — if you use the right one.
ArmorGarage roof coatings are industrial-grade rubber epoxy copolymers that will 100% stop any roof leaks when properly applied — guaranteed for 15 years and recoatable, unlike silicone coatings.
What Is ArmorGarage Roof Coating?
Our Tar & Rubber Roof Coating is a specialized protective layer applied to roofs with materials such as EPDM, TPO, and any type of tar-based roofing — torch down, built-up roofs, and more. It can be applied to flat or pitched roofs.
The coating creates a seamless, weather-resistant barrier that protects against extreme weather, water damage, hail, and harmful UV rays. Apply it once and you have a 15-year guaranteed product that can be recoated when needed — unlike silicone coatings, which cannot.
We don't sell a one-coating-fits-all product. We carry specialized coatings for metal roofs, roofs with ponding water, shingle roofs, and standard flat or pitched tar and rubber roofs.
How Our Roof Coating Stops Leaks
β Seamless Monolithic Application
The primary reason our rubber epoxy roof coatings are so effective is their ability to create a uniform, continuous layer with the lowest permeability ratings in the industry. It forms a single solid layer of epoxy rubber that is impenetrable by water.
Apply our seam mastic to any seams or flashings that need repair, then apply two full coats over your entire roof — it's simply impossible for water to leak through.
β Why Other Coatings Fail — The "Phantom Leak" Problem:
Inferior coatings have poor memory retention — their microscopic pores stretch open from thermal expansion and don't fully close back up. Given enough rain, moisture penetrates right through the coating itself. You look everywhere but you'll never find an actual leak — because it's the coating itself that's leaking. ArmorGarage's 99.9% memory retention means our pores stay sealed.
β Flexibility & Durability
ArmorGarage roof coatings are engineered to expand and contract with your roof's natural movements due to temperature fluctuations. This flexibility prevents the cracks, fissures, and open pores that lead to leaks in rigid coatings.
β Waterproof Barrier
We subject all our roof coatings to extreme weather testing to ensure that no matter the conditions, your roof stays watertight. Our coatings even protect against hail damage — one homeowner with a 100-year-old historical metal roof survived a hailstorm that destroyed 80% of the roofs in his area. Our metal roof coating saved his roof with only slight cosmetic damage fixed with a single pail of coating.
There's a reason Beale Air Force Base chose ArmorGarage to replace the silicone roof coating they were using.
β Seals Existing Damage
Our rubber epoxy coatings effectively seal small cracks, holes, and worn areas — halting existing leaks and preventing new ones. Unlike roofing cement or other temporary fixes, this is a lasting solution.
β The Patching Trap:
Trying to patch and patch leads to multiple layers of multiple products stacked on top of each other — many of which are incompatible. It can reach the point where everything has to be removed, which is difficult and expensive. It's counterintuitive, but when your roof begins to leak, it's always far cheaper in the long run to simply apply one of our roof coatings and be done with your roof for the next 15–20 years.
Coatings for Every Roof Type
β Flat Roofs
Prone to pooling water. We offer both a standard flat roof coating and a specialized ponding water coating for problem areas.
β Metal Roofs
Rust, split seams, expansion. Our metal roof coating has 500% elongation, is heat reflective, and dramatically lowers living space temperatures.
β RV Roofs
Intense sun, heavy rain, constant travel. Our coatings reduce heat transfer to keep you cooler while ensuring long-term leak protection.
β EPDM & Tar Roofs
Our Tar & Rubber coating actually outperforms your roof's original EPDM material. Popular for commercial properties.
β Sloped & Pitched Roofs
Our coatings are viscous enough to apply to pitched roofs without running or dripping. Added protection against UV degradation.
β Shingle Roofs
Our shingle roof coating adds years of protection and seals aging shingles against water infiltration and wind damage.
How to Apply — It's Easier Than You Think
Our roof coatings are simple to apply and can be done by anyone with no prior experience. We offer expert evaluation of your roof's condition and will recommend how to prep and apply the coating. If you prefer to have a handyman or painter do it, a 5-minute conversation with us is all they need.
β Step 1: Surface Preparation
1. Clean the roof of all dirt and debris — make sure it's 100% dry
2. Remove any previous peeling coatings and roof cement patches that are cracking or alligatoring
3. Apply our roof mastic to any seams, screws, or flashings that need sealing
4. Apply two coats of roof coating — that's it
β Step 2: Application Methods
Small flat or pitched roofs — roller and brush
Larger roofs — commercial sprayer (Graco 795 or 1016)
Metal roofs — usually sprayed unless small enough for roller and brush
Not Sure Which Product? An ArmorGarage rep can help you select the right coating for your roof type and guide you through prep and application. It's a very straightforward process once you know what to do.
Why This Is the Most Cost-Effective Roof Solution
Roof replacement is expensive — especially for larger commercial buildings or specialty roofs. ArmorGarage rubber epoxy coatings offer a far more cost-effective alternative by restoring and preserving your existing roof.
