Rooftop deck installation in Lake San Marcos, CA.

You call, we take down the details of the project, and we match you with an insured local deck crew that covers Lake San Marcos. The crew handles the estimate, the written scope, the permit, and the build. You contract and pay the contractor directly.

$15,000-$60,000 depending on area, membrane work, and structural needs. That is a typical San Diego County range, not a quote. The crew matched to your project sets its own price in writing after seeing the site.

Inland community with a lake-effect microclimate, summer highs of 80 to 90 degrees, mild winters, and approximately 12 inches of annual rainfall.. North County Inland rooftop decks in San Marcos and Escondido are less common than in coastal and central neighborhoods, but second-story additions with flat roofs are increasingly popular on large-lot properties where views over the hills are available from higher elevations.

Most liquid-applied and torch-down waterproofing membranes on residential flat roofs last 15-20 years. After that, the membrane becomes brittle and starts to crack at seams and penetrations. The crew assesses the existing membrane condition before recommending repair or full replacement. Building new decking over a failing membrane is the most common and most expensive mistake on rooftop projects.

Most California flat roofs are designed to a live load that includes deck use, but older construction from the 1950s through 1970s should be structurally assessed before adding a deck. The crew coordinates a structural review when the building age or design raises questions, and that assessment goes in the project scope before any materials are ordered.
