Apartment Building Rock Roof Restoration in Long Beach, CA: 8 Tons of Gravel Removed and a 20-Year ASC Warranty

An apartment building rock roof restoration in Long Beach can remove major roof weight, stop chronic leaks, and create a lighter long-term maintenance path when the existing roof can be converted correctly. On this project, Golem Roofing removed nearly 8 tons of gravel, rebuilt the surface with a reinforced acrylic and silicone coating system, and reduced the finished roof weight to under 1.5 tons.

Project Snapshot

• Location: Long Beach, California
• Property type: Multi-family apartment building
• Existing roof: Leaking tar-and-gravel rock roof
• System: Fluid-applied reinforced acrylic and silicone coating system
• Weight reduction: Nearly 8 tons of gravel removed; new system under 1.5 tons
• Protection: 20-year ASC manufacturer NDL warranty, Golem Roofing’s 20-year contractor no-leak warranty for this project, and a $250,000 third-party guarantee

The Challenge: Heavy, Leaking Gravel Roofs

Tar-and-gravel roofs can be difficult for owners to manage because the leak source is often hidden under rock. The system is heavy, hard to inspect visually, and can keep failing as age, UV exposure, seams, and drainage issues compound over time.

For this Long Beach apartment building, a traditional tear-off would have meant a messy and expensive process: vacuuming tons of gravel, removing the old assembly, and installing another heavy asphalt-based roof. The owner needed a cleaner path that would stop leaks, reduce structural load, and protect the property financially.

The Engineering Solution: Convert the Rock Roof

Golem Roofing converted the obsolete rock roof into a reinforced fluid-applied system. The goal was not only to waterproof the building, but to reduce roof load and create a sustainable maintenance path for future recoats.

1. Gravel removal and substrate prep: Nearly 8 tons of rock and gravel were removed from the roof deck, then the surface was pressure washed and cleaned.
2. Inspection checkpoints: The cleaned roof deck passed city inspection and a technical audit by ASC manufacturer inspectors before the next system layer.
3. Reinforced acrylic armor: A base coat of acrylic was applied, polyester reinforcement fabric was embedded across 100% of the roof surface, and a second acrylic layer encapsulated the fabric.
4. Silicone weatherproof finish: A premium silicone finish coat added UV protection and ponding-water resistance.

The Breakthrough: Weight Savings and the “7 Lifetimes” Advantage

The finished system reduced the roof load by more than 6.5 tons, dropping from nearly 8 tons of gravel to less than 1.5 tons for the new coating assembly. That matters because California buildings have practical and code-related limits around roof weight and roof-layer buildup.

Because the new system is so light, the roof can be cleaned and recoated up to seven times at 20-year intervals before reaching the weight of the original rock roof. In practical terms, the owner can keep renewing the waterproofing system for decades at a fraction of the disruption and cost of repeated replacement.

Warranty and Third-Party Protection

This eligible commercial project was backed by a 20-year ASC manufacturer NDL warranty, Golem Roofing’s 20-year contractor no-leak warranty for this project, and a $250,000 third-party guarantee. That combination gives apartment owners and property managers a stronger documentation package than a basic repair invoice.

For owners comparing roof systems, warranty clarity is part of the scope. The best decision is not just “repair or replace.” It is whether the roof can be restored, reinforced, inspected, and protected with a system that matches the property.

FAQ

Can a tar-and-gravel roof be restored instead of torn off?

Sometimes. The roof must be inspected to confirm deck condition, moisture risk, adhesion, drainage, and whether the old surface can be converted into a reinforced coating system safely.

Why remove gravel before applying a coating system?

Removing gravel allows the contractor to inspect and prepare the actual roof surface, reduce roof weight, address defects, and build a cleaner reinforced membrane system.

How much weight did this Long Beach project remove?

Golem Roofing removed nearly 8 tons of gravel and reduced the finished system weight to under 1.5 tons, creating more than 6.5 tons of roof-load reduction.

What is the advantage of a recoatable roof system?

A recoatable roof system can be cleaned, inspected, repaired, and renewed with future coating applications, extending service life without repeating a full tear-off each cycle.
