Aged Flat Roof Overview

This homeowner reached out after dealing with recurring leaks and signs of interior damage from the front part of his roof. At SLOG, we offered a Free Roof Inspection and Full Roof Analysis to evaluate the condition. We discovered a flat roof system (mod-bit) with ponding water, poor drainage, and visible aging of materials. The client had also attempted to request estimates from other contractors but found a lack of transparency and incomplete solutions. Our detailed inspection gave him clarity on his situation — and a real path forward.

What We Found

  • Ponding water compromising the roofing layers.
  • A deteriorated section of mod-bit that was contributing to the leak.
  • Coping tiles and flashing showing signs of weather-related damage.
  • No proper pitch directing water to the gutters.

After reviewing the situation, we offered two clear solutions. That’s when we proposed the perfect solution: restore with premium coating instead of replace.

The Solution: Castagra Ecodur+ premium coating

  1. Inspection & Planning
    We began with a thorough Free Inspection of the flat roof, using photo documentation and our in-house tools to track ponding areas, degraded layers, and overall roof health. After understanding the client’s budget and expectations, we aligned on a Castagra coating solution — the most efficient route to restoring his roof and protecting his property for years to come.
  2. Partial Tear-Off & Roof Prep
    Before applying any coating, we performed a partial tear-off of the mod-bit section with the most damage.
    We then re-pitched that section to create water flow toward the existing gutter system. This critical step would help prevent future ponding.
  3. Repairs & Cleaning
    Our crew repaired small cracks and weathered edges. We removed any debris and made sure the entire surface was clean and dry before coating. A blow-dry process was used to eliminate moisture pockets.
  4. Application of Castagra Ecodur+ (30 mils)
    With precision and care, we coated the entire roof with 30 mils of Castagra Ecodur+, creating a seamless barrier resistant to UV rays, ponding water, and extreme weather conditions.

Final Outcome

The project was completed in just 3 days, with zero delays. The homeowner was impressed with the professionalism, efficiency, and clarity throughout the entire process.
He wrote us a detailed Google review, highlighting how Santiago and the crew explained every step, answered questions honestly, and even resolved issues related to the coping tiles — without additional charges.

Weeks later, after storms and strong winds, the client reported no recurrence of leaks and shared that he would recommend SLOG and Castagra Ecodur+ to anyone looking for transparency, reliability, and results.

When a Repair Is the Smartest Investment

Not every roof needs a full replacement — and that’s exactly why we believe in customized solutions. In this case, the homeowner saved up to 35% by applying a premium coating compared to the cost of a new mod-bit installation, without sacrificing quality or peace of mind.
If you suspect damage or aren’t sure what your roof needs, book a Free Inspection with Slog Group.
