Flat Roof Waterproofing in Manhattan Beach.
Flat roof waterproofing in Manhattan Beach, CA (90266) is a coastal specialty — the modern flat and low-slope homes that define the Tree Section and Sand Section live or die by their seams, drainage, and the metal that salt air is always working to corrode. Samuel Roofing Inc. is a family-owned, owner-operated roofing company serving the South Bay, and we waterproof the whole system, not just the spot that's showing. 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 Manhattan Beach
Manhattan Beach is full of flat and low-slope roofs: the modern architectural rebuilds throughout the Tree Section and Sand Section, contemporary additions and rooftop decks, and the low-slope sections that tie pitched homes together. These roofs don't shed water the way a steep roof does — they rely entirely on an intact membrane, properly detailed seams and penetrations, and drainage that actually moves water off the roof. Near the water, salt air adds a second front, corroding drains, scuppers, and edge metal.
Systems we install
We match the system to the roof. TPO is a clean, reflective single-ply membrane well suited to many low-slope homes here. Torch-down and modified-bitumen systems — we use leading manufacturers membranes — give a durable, multi-ply build that handles foot traffic on decks and ties cleanly into walls and curbs. Silicone coatings can extend the life of a sound but aging roof by sealing the surface and seams. We'll recommend the right one for your slope, drainage, and exposure, and name it in your written scope.
Marine-air & ponding issues at the coast
Two problems dominate coastal flat roofs. The first is ponding — water that sits in low spots because slope or drainage is inadequate, accelerating membrane breakdown and finding any weak seam. We re-establish positive drainage and detail the drains and scuppers so water leaves the roof. The second is corrosion — salt air eats drains, edge metal, and fasteners — so we specify corrosion-resistant components and seal the transitions where metal meets membrane.
Our waterproofing process
We start with a drone inspection to map ponding, seam condition, and corroded details. Then we prep the surface, repair or re-deck any soft sheathing, and rebuild the waterproofing: fully welded or torched seams, reinforced detailing at every penetration, curb, and wall, and re-established drainage. We document the finished system from the air, and the work carries our 10-year workmanship warranty.
Neighborhoods we serve
We waterproof flat roofs across Manhattan Beach: the Sand Section near the Strand, the Tree Section, the Hill Section, East Manhattan, and around Manhattan Village, along Highland Avenue and Sepulveda Boulevard.
A recent Manhattan Beach flat-roof project
A homeowner in the Sand Section in 90266 had a low-slope roof with a rooftop deck that was ponding and leaking into the room below. The drone survey showed standing water at a blocked drain and split seams nearby. We re-established drainage, rebuilt the seams and deck detailing in a leading manufacturers system, and re-flashed the drain with corrosion-resistant metal. The roof drained clean afterward, and they had a full drone record. Written pricing. No pressure. No surprises.

Manhattan Beach roofing questions
Why do flat roofs leak in Manhattan Beach?
Flat and low-slope roofs leak at seams, penetrations, and low spots where water ponds. Marine air also corrodes drains and edge metal. We waterproof the whole system — seams, drains, and details — rather than just sealing the spot that shows.
Which waterproofing 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, and exposure. On the coast we favor systems that resist ponding and salt.
Can you fix ponding water?
Often, yes. Ponding usually comes from inadequate slope or blocked drainage. We re-establish positive drainage and detail the drains and scuppers so water leaves the roof instead of sitting on it.
