The city changed its name from Lake Worth to Lake Worth Beach in March 2019, mainly to separate its identity from unincorporated areas to the west and to lean into its beach access. The housing stock is genuinely old by South Florida standards: around 1,000 small cottages built roughly between 1913 and 1949, giving the city one of the largest concentrations of that housing type in the state. The College Park neighborhood was mostly built 1925-1949 and Old Lucerne runs from about 1913 to 1951 — this is a pre-hurricane-code, wood-frame-heavy building stock, not the concrete-block-and-tile construction that dominates most of Palm Beach County.
That age shows up in the roofing: a lot of original wood roof decking, homes that have been re-roofed multiple times over a century with a mix of asphalt shingle and metal, and decking that sometimes needs replacement (not just a new roof covering) once it's opened up. Newer construction and the condo/multifamily buildings closer to the water use more standard concrete tile or modified bitumen, but the defining character of this market is old wood-frame cottages, not tract-built tile roofs.
Lake Worth Beach has six recognized historic districts — College Park, Old Lucerne, Old Town Commercial District, Northeast Lucerne, Southeast Lucerne and South Palm Park — three of which are listed on the National Register of Historic Places, plus individually listed landmarks like the Gulf Stream Hotel and Old City Hall. Visible roof work on a contributing structure in one of these districts needs a Certificate of Appropriateness from the city before a permit is pulled, and the city publishes its own roof-replacement checklist for exactly that review. Outside the historic districts it's a standard permit, but on this housing stock, checking district status before scheduling work is worth the extra call.
