Can You Extend the Lifespan of an Asphalt Roof?

Every property owner wants more out of their system. Replacement work is expensive, and if you can avoid the constant worry of an impending roof failure, you’d pursue the opportunity to do so.

Our roof coating systems give ageing asphalt roofs a practical way to stay in service longer. The idea is straightforward: by repairing the existing surface, sealing cracks and vulnerable areas, and creating a seamless waterproof membrane across the roof, we can help reduce the wear that leads to ongoing leaks and premature replacement.

Plenty of short-term fixes simply mask the problem. Our approach is backed by manufacturer-approved systems, experienced applications, and superior warranties.

When Is It Time for Asphalt Roof Restoration?

Many business owners aren’t sure when asphalt roof restoration becomes the right choice. The truth is, you don't have to wait until your system is falling apart before taking action. There are clear signs that it’s time to book an inspection and get the process started with a free quote.

Some of them include:

  • Ponding water that doesn't drain away
  • Cracks beginning to form across the roof surface
  • Blisters or areas where the membrane has started to lift
  • Worn or loose granules exposing the underlying surface
  • Leaks appearing after heavy rain or melting snow
  • Open seams around flashings, vents, or rooftop equipment

How Do Asphalt Roof Leaks Start?

Flat commercial asphalt roofs are exposed to the same weather, temperature swings, and day-to-day demands year after year. Every system will eventually begin to show signs of wear. It’s just a matter of when and where the issues develop.

Asphalt roof leaks will begin where the roof surface has started breaking down. Cracks, failing seams, worn flashing details, and openings around rooftop equipment can all give water a way in. This creates the conditions for rapid decline and often desperate, unproductive workarounds. To help you break that cycle, we repair, prime, and seal your roof before applying layers of roof coating to both correct problem areas and prevent new ones from forming.

Why Preparation Matters for Asphalt Roof Coatings

The coating may be the final result, but preparation is where the restoration really begins. Every step that follows depends on getting the roof ready first.

Once we've inspected the roof and confirmed it's a good candidate for restoration, we begin by thoroughly power washing the existing surface to remove loose material and years of buildup. From there, we repair damaged areas, including cracks, blisters, and sections of the substrate that need attention before the coating system is applied.

Taking the time to prepare the roof properly lays the groundwork for a consistent application. The attention to detail here is also necessary for the completed system to have that reinforced, monolithic finish it's designed to achieve.

What Does a Base Sealer Do for an Asphalt Roof?

The ASTEC® Base Sealer we use is one of the products we trust for this early stage of work. It first saturates the high-tensile-strength polyester cloth used to reinforce the most vulnerable areas, such as seams and vents. Once those details have been addressed, one or more coats of that same base sealer are applied across the roof before the finish coats are installed, creating the bond between the existing surface and the roof coating system.

The base sealer has an important role to play. As it cures, it fills small cracks and irregularities while forming a continuous membrane across the roof. That added layer helps create a stable foundation for the finish coats and strengthens the roof's resistance to water intrusion.

Do Roof Coating Systems Enhance Material Performance?

Roofing performance isn't measured by technical specifications alone. As a property owner, you measure it by a simple outcome: your roof keeps the weather out, your building stays protected, and you're not constantly dealing with new problems.

A fluid-applied roof coating system is designed to improve that performance in several key areas; here are a few of them:

  • Waterproofing: Creates a seamless membrane that helps keep moisture out
  • Energy efficiency: Reflects sunlight to help reduce cooling costs
  • Weather resistance: Improves protection against rain, UV exposure, and weather
  • Surface durability: Adds another protective layer that stands up to wear
  • Corrosion resistance: Helps protect the roof from many airborne corrosives
  • Flexibility: Remains pliable as the roof expands and contracts

Why Does It Matter if an Asphalt Roof Is Pliable?

A roof needs to move with the conditions it faces every day.

As temperatures rise and fall, roofing materials naturally expand and contract. If a coating becomes too rigid, that movement can place added stress on the surface. Our pliable coatings remain flexible as your roof moves, helping it maintain a continuous waterproof barrier through changing weather and seasonal conditions.
