Flat Roof Waterproofing in Redondo Beach.
Flat roof waterproofing in Redondo Beach, CA (90278) is steady work in a city built heavily on condos, townhomes, and low-slope homes — many a short walk from King Harbor and the salt air that comes with it.

Every project starts with a free on-site inspection, drone documentation, and a written roof report. We hold a CSLB C-39 roofing license (#1137536), we're licensed, bonded and insured, and we're Google Guaranteed with a 5.0-star rating on Google.
Flat & low-slope roofs in Redondo Beach
Redondo's flat and low-slope roofs sit on its many condos and townhomes across North Redondo and Golden Hills, on contemporary homes and additions in South Redondo and the Hollywood Riviera, and on mixed-use buildings near King Harbor. These roofs depend on an intact membrane, well-detailed seams and penetrations, and drainage that clears the roof — not on slope to shed water. Near the coast, salt air corrodes the drains, scuppers, and edge metal that drainage relies on.
Systems we install
We match the system to the roof and its use. TPO is a clean, reflective single-ply membrane suited to many condo and low-slope roofs. Torch-down and modified-bitumen systems — we use leading manufacturers membranes — give a durable, multi-ply build that handles foot traffic and ties cleanly into parapets, curbs, and shared walls between units. Silicone coatings can extend the life of a sound but aging roof by sealing the surface and seams, a practical option for an HOA building that isn't ready for a full membrane replacement. We recommend the right one for your slope, drainage, and exposure, and name it in your written scope so an owner or board knows exactly what's going on the roof.
Marine-air & ponding issues at the coast
Two problems dominate. Ponding — standing water from inadequate slope or blocked drains — degrades the membrane and finds any weak seam; we re-establish positive drainage and detail the drains and scuppers. Corrosion — salt eating drains, edge metal, and fasteners near the water — we counter with corrosion-resistant components and sealed metal-to-membrane transitions. On shared condo roofs, the transitions between units and at parapets get particular attention.
Our waterproofing process
We start with a drone inspection to map ponding, seam condition, and corroded details across the full roof. Then we prep the surface, repair or re-deck soft sheathing, and rebuild the waterproofing: fully welded or torched seams, reinforced detailing at every penetration, curb, and parapet, and re-established drainage. We document the finished system from the air, provide board-ready records on HOA jobs, and back the work with our 10-year workmanship warranty.
Neighborhoods we serve
We waterproof flat roofs across Redondo Beach: North Redondo and Golden Hills, South Redondo, the Hollywood Riviera, and around King Harbor, along Catalina Avenue, Pacific Coast Highway, and Artesia Boulevard.
A recent Redondo Beach flat-roof project
A homeowner in South Redondo in 90277 had a low-slope addition ponding and leaking after winter rains. The drone survey showed standing water at a blocked scupper and split seams across the addition. We cleared and re-detailed the scupper, re-established slope, and rebuilt the seams in a leading manufacturers system with corrosion-resistant edge metal. The roof drained clean afterward, fully documented. Written pricing. No pressure. No surprises.

Redondo Beach roofing questions
Do you waterproof condo and HOA flat roofs?
Yes. Redondo's many condos and townhomes carry shared low-slope roofs. We provide board-ready written scopes, coordinate access across units, and document the finished waterproofing system from the air.
Which systems do you install?
We install TPO, torch-down and modified-bitumen membranes, and silicone coatings, choosing the right one for your roof's slope, drainage, traffic, and coastal exposure.
What causes ponding on a Redondo flat roof?
Ponding comes from inadequate slope or blocked drains and scuppers. We re-establish positive drainage and detail the drains so water clears the roof instead of sitting and breaking down the membrane.
