Roof leak sealant and coating service restores waterproofing on aging-but-sound roofs: we repair the active failures first, prepare the surface properly, then apply professional-grade sealants and elastomeric coatings to manufacturer spec — extending roof life by years. Older housing stock means multiple roofing layers and long-past-due flashing details are common.

Maintaining Your Coated Roof

Coated roofs need light maintenance: keep drains clear, recoat high-wear areas as needed, and have the coating inspected every few years. Touch-ups are cheap when caught early.

We offer maintenance plans that keep your coating performing for its full rated life — and document everything for warranty purposes. Mature street trees drop heavy seasonal debris into valleys and gutters.

• Inspect coating every few years
• Touch up wear areas early
• Maintenance plans available
• Keep drains and surfaces clear

Our Process: Repair First, Coat Second

Anyone who coats over active leaks is selling you a failure. We repair all breaches, re-flash details, replace wet insulation, and verify the roof is dry — then prepare the surface: cleaning, priming, and detailing seams and penetrations.

Only then does the coating go on, at the specified thickness in the specified conditions. Older housing stock means multiple roofing layers and long-past-due flashing details are common. This is why our coatings last and bargain coatings don't.

• All leaks repaired first
• Wet insulation replaced
• Proper cleaning and priming
• Seams and details reinforced

Energy Benefits Beyond Waterproofing

Reflective coatings bounce solar heat instead of absorbing it — cutting surface temperatures by 50+ degrees on summer days. That means lower cooling bills, less thermal cycling stress on the membrane, and a more comfortable building.

For Bellflower properties with big flat roof areas, the energy savings alone can justify the project over a few cooling seasons. Bellflower is the adjacent city of postwar 1940s–60s homes, many with original-era roof structures.

• More comfortable interiors
• 50°+ cooler roof surfaces
• Lower cooling costs
• Less thermal cycling damage
