Flat Roofing in Santa Barbara, California

The flat roof covers the garages, the additions, and the commercial buildings across Santa Barbara. The low slope needs the right membrane for the fog and the rain. Flat roofing in Santa Barbara installs and repairs the roofs that handle the Central Coast climate.

Why Flat Roofs Need the Right System in Santa Barbara

• The ponding water — the low slope holds the water and the membrane degrades
• The fog and the damp — the constant moisture feeds the algae and the moss
• The winter rain — the steady rain from November through March tests the seams
• The salt air — the coastal air corrodes the flashing and the metal
• The foot traffic — the maintenance visits can damage the membrane

How We Install Flat Roofs in Santa Barbara

1. Inspect the deck — check the condition and the slope of the roof
2. Prepare the surface — clean and prime the deck for the membrane
3. Install the insulation — the polyiso board improves the energy efficiency
4. Install the membrane — the TPO or the modified bitumen in the manufacturer’s pattern
5. Install the flashing — the corrosion-resistant edge metal, pipe boots, and wall flashing
6. Test the system — the flood test or the leak test confirms the integrity

Preventing Roof Problems in Santa Barbara

• Check for the ponding water after the rain — the standing water degrades the membrane
• Use the corrosion-resistant flashing — the salt air eats the standard metal
• Clear the debris regularly — the oak and eucalyptus leaves trap the moisture
• Limit the foot traffic — the membrane punctures are the common leak point

Expert tip: in Santa Barbara, the flat roof needs the drainage and the corrosion-resistant flashing to work. The ponding water degrades the membrane and the salt air eats the metal. Both need to be addressed.
