Flat and low-slope roofs are common on San Francisco's Edwardian flats, TIC buildings, and commercial-residential mixed-use properties. These roofs rely on continuous membrane integrity rather than the drainage slope of pitched surfaces, making any breach, open seam, or ponding water area a significant leak risk. Deluxe Roof Repair diagnoses and repairs the full range of flat roof systems including modified bitumen, TPO, and built-up roofing (BUR) assemblies.
Repair work addresses the most frequent failure points: open laps where membrane sheets have separated, blistering and bubbling that indicates moisture trapped beneath the surface, cracked or loose parapet cap flashing, and deteriorated roof drains or scupper boxes. For roofs that are structurally sound but showing surface aging, an elastomeric or acrylic reflective coating can restore waterproofing performance and reduce heat gain — a benefit in San Francisco's microclimates that experience significant summer sun on south-facing rooftops.
We assess ponding water patterns and, where drainage improvements are within scope, address them through auxiliary drains or tapered insulation recommendations. Our flat roof work is backed by a detailed inspection report noting all repaired areas and any sections that should be monitored at the next service interval, giving building owners full transparency into the roof's condition.

Common Questions
How do I know if my flat roof needs a repair or a full replacement?
If the membrane is less than 15–20 years old, leaks are isolated to specific areas, and the substrate is dry and structurally sound, targeted repairs and coating are usually the right choice. If there are widespread blisters, the membrane has exceeded its expected service life, or moisture testing shows saturated insulation across large sections, replacement is more cost-effective. We perform a full assessment before recommending either path.
What is a roof coating and how long does it last?
A roof coating is a fluid-applied, elastomeric membrane — typically acrylic or silicone — that is rolled or sprayed over an existing flat roof surface to restore waterproofing and add UV and thermal protection. Quality coatings applied at the correct thickness last 10–15 years and can often be recoated at the end of that period, extending the roof's service life without a full tear-off.
