Marina Bay Roofing is a San Francisco roofing contractor providing roof replacement, roof repair, and roof maintenance for residential and commercial properties across the city. Whether you’re dealing with storm damage or need an emergency roof repair, our roofing experts handle every job for homeowners and business owners with code-compliant materials and warranty-backed workmanship.
Most residential roof replacement projects are completed in two to five days, depending on the size of the roof, the roofing material selected, and permit timing with the city. A larger reroofing job on a low-slope roof or a complex structure may take longer than a straightforward shingle job.
San Francisco’s microclimates create real challenges for roofing — a home in the Sunset deals with heavy fog, while one in Bernal Heights faces direct sun and wind. As experienced contractors, we evaluate each property’s exposure, roof age, and condition before recommending repair or replacement.
Deferred upkeep is the top reason San Francisco properties end up needing emergency roof repair instead of a planned replacement. Small issues — a lifted shingle, a cracked flashing seal, a clogged drain — compound quickly in a wet, foggy climate. Routine roof checks every one to two years catch these problems early.
Roof replacement is our core service and the most significant investment most owners make in a property’s long-term protection. Our team handles a complete reroof from tear-off through final inspection, using quality materials rated for coastal exposure, and we hold every job to the same quality standard regardless of size. We walk every owner through material options, code requirements, and warranty coverage before installation begins.
Not every roofing problem calls for a full replacement. Our roof repair addresses leaks, damaged shingle sections, flashing failures, and storm damage without unnecessary cost. We handle residential roof repair for single-family homes and multi-unit buildings alike. As a roof repair service, we diagnose the root cause before repairing it, so the same problem doesn’t return after the next storm — that is expert roof repair, not a quick patch.
An active leak or storm event cannot wait for a scheduled appointment. Our emergency roof repair crew responds quickly to stop water intrusion, cover exposed sections, and stabilize the property until permanent repair services can be completed.
New construction, additions, and accessory dwelling units all require professional roof installation. Our installation crews work with a range of roofing systems, matched to the structure’s slope, drainage needs, and the surrounding block’s exposure. Every installation follows manufacturer specifications and local code, and our contractors document each stage so property owners can see the quality of work at every step.
A thorough roof inspection identifies problems before they become expensive. We check flashing, shingles, drainage, and ventilation, and provide a written roof assessment homeowners can use for insurance, financing, or pre-sale purposes.
Ongoing roof maintenance extends the life of any roofing system. Our maintenance services include debris removal, drain clearing, flashing checks, and minor repairs scheduled on a regular basis to prevent small issues from becoming major damage.
Marina Bay Roofing also serves San Francisco businesses and property managers, working around business hours to minimize disruption to daily operations.
Shingles that curl, crack, or go missing across large sections usually signal the roofing material has reached the end of its service life. Isolated shingle wear can often be repaired, but widespread damage points toward a full roof replacement rather than another patch.
A roof leak that returns after repair, or shows up in more than one spot, often means the underlying system has failed rather than a single isolated area. At that point, repair becomes a temporary fix rather than a lasting solution.
A roof deck that sags or feels soft when walked on indicates water has reached the structural sheathing beneath the roofing material. This is a safety issue that typically calls for a full reroof rather than a surface-level repair.
Most roofing in San Francisco reaches the end of its expected service life between twenty and thirty years, depending on the material. If your roof is approaching that range, a proactive roof replacement is more cost-effective than repeated repair calls.
We start with a free roof inspection of the existing structure, checking the deck, flashing, ventilation, and drainage. This assessment gives owners a clear picture of condition before installation begins.
Once that step is complete, we walk owners through material options suited to San Francisco's climate, covering durability, appearance, and warranty coverage for each type of roof.
New material is installed according to manufacturer specifications and local building code, with flashing, ventilation, and drainage details addressed at every seam.
Once installation is complete, we walk the property with the owner, review the finished system, and provide warranty documentation for the completed project..
Winter storms bring heavy rain and wind that expose weak points in aging roofing across San Francisco. Storm damage often shows up as a new roof leak, a lifted shingle, or flashing failures around chimneys and vents. Our team handles storm damage repairs quickly, stabilizing the structure and preventing water from reaching the interior while a permanent fix is scheduled.
A leaky roof rarely originates exactly where water appears inside the building, which is why an experienced repair diagnosis matters. We trace every problem back to its source before completing the repair.
Wind and fog exposure loosen shingle edges over time. Addressing these small issues early prevents water from reaching the underlayment below.
This roof type is common on commercial buildings and some residential additions in San Francisco. Ponding water, membrane cracking, and drainage failures are the issues we see most often..
When water reaches the deck, the wood sheathing beneath the material can rot or weaken. Repairing affected sections is essential before new material goes on.
We install materials built for wind, moisture, and UV exposure, sourced from manufacturers with strong warranty programs, with quality control checked at every stage. The right material choice extends the life of the entire system, and quality installation matters just as much as the product itself.
Our team installs asphalt shingle, metal, tile, and membrane systems for residential and commercial projects alike, matching the type of roof to a property’s structure, slope, and surrounding exposure.
