The Challenge: Tear-Off or Restore?

The HOA was dealing with a large, aging flat roof system that had already gone through prior repair attempts. Those repairs were no longer holding, and most contractors treated a costly tear-off and full roof replacement as the only responsible path.

The property made the decision more complex. The buildings were three stories tall, access was restricted, and the existing roof surface was heavily weathered and soiled. For an HOA board, that kind of project is not just a roofing issue. It can mean resident disruption, noise, reserve-budget pressure, and weeks of coordination.

Why Silicone Restoration Was the Better Fit

After inspection, Golem Roofing identified a more strategic solution: restore the existing flat roof instead of replacing it. A silicone restoration system can be a strong option when the roof is still a candidate for cleaning, repairs, reinforcement, and a properly specified coating system.

This is not a shortcut. Restoration only works when preparation, repairs, adhesion, coating thickness, and manufacturer requirements are handled correctly. That is why the project was built around documentation and quality control, not just coating the surface.

How Golem Roofing Executed the Restoration

• Deep cleaning and preparation: The roof was pressure washed and degreased to remove industrial dirt and prepare the substrate for adhesion.
• Comprehensive repairs: Historical leak points, compromised seams, penetrations, and flashing details were reinforced before coating.
• Silicone coating application: A high-solids, ponding-water-resistant silicone membrane created a seamless waterproofing barrier.
• Manufacturer quality control: Two separate on-site inspections were completed with the material manufacturer’s technical experts.

The Result: Less Disruption, Lower Cost, Better Protection

By choosing restoration over replacement, the Signal Hill HOA avoided unnecessary tear-off debris, reduced construction disruption for residents, and saved thousands of dollars in labor and disposal costs. The reflective cool-roof surface can also help lower rooftop heat gain, which matters for multi-family buildings in Southern California.

The finished system was backed by a 20-year manufacturer NDL warranty, Golem Roofing’s 20-year contractor no-leak warranty for this project, and a $250,000 third-party guarantee. For an HOA board, that combination matters because it converts the roof decision into a documented, protectable capital improvement instead of a guess.

What HOA Boards Should Ask Before Replacing a Flat Roof

Before approving a full tear-off, HOA boards and property managers should ask whether the roof is truly past restoration eligibility. The answer depends on moisture, deck condition, existing assembly, seams, drainage, penetrations, prior repairs, and manufacturer requirements.

FAQ

Can an HOA flat roof be restored instead of replaced?

Yes, but only when the roof is still a restoration candidate. A qualified inspection should confirm substrate condition, moisture risk, seams, drainage, repairs, and whether the system can meet manufacturer requirements.

Why does a manufacturer NDL warranty matter?

An NDL warranty, or No Dollar Limit warranty, can provide stronger protection for eligible commercial and HOA projects because the manufacturer stands behind the approved system under the warranty terms.

Does silicone restoration help with ponding water?

Silicone is often used on flat and low-slope roofs because it can provide strong UV resistance and ponding-water resistance when the roof is properly prepared and the coating system is installed to specification.

Yes. Golem Roofing serves HOA, apartment, commercial, and multi-family properties in Signal Hill, Long Beach, the South Bay, Los Angeles, and Orange County.
