What Is Roof Coating and How Does It Work?
Roof coating is a seamless, liquid-applied membrane that seals your existing roof surface. It works by creating a watertight barrier that blocks leaks, reflects UV rays, and prevents further wear. We start by inspecting your roof for rot, decay, sagging, or granule loss. If the structure is sound, we clean the surface thoroughly, repair any cracks or blisters, and then apply the coating in multiple coats to ensure full coverage. The result is a roof that resists water, heat, and weathering for years.
This service is ideal for flat or low-slope roofs common on Newark's commercial buildings and many older homes. It's not a fix for severe structural damage—if your decking is rotted or your roof is sagging, a tear-off and replacement is the honest recommendation. But for roofs with end-of-life wear but no major structural issues, a coating can add a decade of life at a fraction of replacement cost.
We use self-adhered membranes at seams and flashings to reinforce vulnerable spots. The coating itself is applied with a sprayer or roller, depending on the product and roof shape. Once cured, it forms a monolithic layer that flexes with temperature changes—critical in Newark's climate, where summer humidity and nor'easter winds put constant stress on roofing materials.
When Do You Need Roof Coating?
You might need roof coating if your roof is leaking, showing widespread cracking, or losing granules. Water that seeps through small gaps can wick into the decking, causing rot and decay that spreads quickly. If you notice peeling paint on the ceiling, damp spots in the attic, or visible cracks on the roof surface, a coating can seal those entry points before they become major repairs.
Roof coating is also a smart choice when your roof is still structurally sound but showing signs of aging. If your shingles are curling or the membrane is blistering, a coating can restore the surface and buy you time. It's not a permanent solution—eventually, every roof needs replacement—but it's a cost-effective way to manage your budget and avoid an emergency tear-off.
We've applied coatings to roofs across Newark's five wards, from the brownstones of the North Ward to the flat commercial roofs near the Prudential Center. Each job starts with a thorough inspection and a clear explanation of what we find. If a coating won't solve the problem, we'll tell you that too.
What Does Roof Coating Cost and How Long Does It Take?
Roof coating costs $1.50 to $4.00 per square foot, depending on the product, the condition of your roof, and the complexity of the job. A typical 1,500-square-foot roof runs $2,250 to $6,000. That's a fraction of the $10,000 to $15,000 a full replacement would cost. We provide a free estimate with no pressure, and we'll walk you through the numbers so you know exactly what you're paying for.
Most residential coating jobs take one to two days. Commercial roofs with multiple penetrations or complex flashing can take longer. We use ring-shank nails for any needed fastener replacement, and we hand-seal every penetration—vents, pipes, skylights—to ensure a watertight seal. The coating cures within 24 hours, and you can walk on it after that.
We stand behind our work with a satisfaction guarantee and a workmanship warranty. If you have questions about whether a coating is right for your roof, call us at 877-854-0330. We'll give you an honest answer and a free estimate.
Frequently Asked Questions
Can roof coating be applied over any roof?
Roof coating can be applied over most roofs—asphalt shingles, metal, single-ply membrane, and built-up roofs—as long as the surface is clean, dry, and structurally sound. We don't recommend coating over roofs with active rot or sagging; those need replacement first.
How long does a roof coating last?
Roof coating lasts 10–15 years with proper maintenance. The lifespan depends on the product, the roof's exposure to sun and weather, and how well the surface was prepared. We'll tell you what to expect based on your specific roof.
Will roof coating stop a leak?
Roof coating stops leaks caused by cracks, blisters, or failed seams. It won't fix a leak from structural damage or a roof that's reached the end of its life. We'll inspect first and let you know if a coating will solve the problem or if you need a repair or replacement.
