Lower than most — the typical roofer in California sits at 0.8%. A higher share is a reason to read the critical reviews below, not a verdict.

The critical reviews

The one and two-star reviews, first. These are what a star average hides, and they are the reason this page exists.

We hold no one or two-star review text for Surfacing And Waterproofing. That is not the same as there being none — it means our capture did not reach any. The rating breakdown above is Google’s own count and is the number to go on.

    This was a pretty demanding commercial build in West Hollywood, and waterproofing touched almost every phase of the project. There were podium decks, elevator pits, planters, below grade walls, and a rooftop common area that all required …

    We're proud to be a leading waterproofing company in Los Angeles, it was a privilege to be part of your below grade and above grade waterproofing commercial project.

    We interviewed several companies before awarding this portion of the project. What separated them wasn't the bid it was their experience with larger commercial work. The building had multiple waterproofing systems being installed at different stages, from the foundation and basement waterproofing to exterior podium decks and TPO roofing transitions. They stayed involved from the early phases through closeout and were responsive anytime the field team had questions. It's refreshing to work with a subcontractor that understands the pace of commercial construction in Beverly Hills and keeps commitments.

  • 5 out of 5Rafiq Alfaraha month ago

    This was a large commercial project with multiple buildings, underground parking, and several rooftop amenity spaces, so there wasn’t much room for mistakes. The waterproofing scope included below-grade waterproofing, commercial deck waterproofing, TPO roofing tie ins, and sheet metal throughout different phases of construction. What I appreciated was that they understood how to work on an active jobsite with dozens of subcontractors. They kept to the schedule, communicated well with the superintendent, and handled inspections without creating delays for the trades behind them. On a project this size in Los Angeles, having a subcontractor you don’t have to constantly manage is a huge advantage

  • 5 out of 5Laffy2 months ago

    I’ve managed properties for a while and commercial deck waterproofing is one of those things you don’t want to cut corners on. We had a building in West Hollywood with a roof deck over occupied space and a few balconies that were showing their age. The crew handled the roof deck waterproofing, updated several sheet metal details, and applied new balcony deck coatings where needed. The work was phased so tenants weren’t constantly being disrupted, and everything was completed without creating new headaches. It’s rare that a project this involved ends up being this straightforward.

    What stood out to me was how early they caught a few things that could have become expensive later. This was a new build with multiple trades working at the same time, and they pointed out a couple waterproofing details that would’ve been buried behind finishes if nobody had noticed. It saved us from having to tear things apart down the road. They took care of their scope, kept the project moving, and made life easier for everyone involved.
