Roof Waterproofing in San Clemente, California

The winter rain in San Clemente finds every gap in the flat roof and the low slope. The waterproof membrane seals the surface and the water runs off. Roof waterproofing in San Clemente protects the flat roofs and the low-slope additions.

Why San Clemente Roofs Need Waterproofing

• The flat roof and the low slope — the low slope holds the water and the membrane needs the seal
• The winter rain — the steady rain from November through March tests the seals
• The garage and the addition roofs — the flat roofs are the common leak point
• The ponding water — the standing water degrades the membrane and the seal
• The salt air — the coastal air corrodes the flashing and the metal

How We Waterproof Roofs in San Clemente

1. Inspect the roof — check the condition, the cracks, and the leaks
2. Clean the surface — the power wash removes the dirt, the salt, and the debris
3. Repair the damage — patch the cracks, the blisters, and the seams
4. Apply the primer — the primer bonds the waterproofing to the surface
5. Apply the waterproof membrane — the liquid or the sheet membrane in the manufacturer’s pattern
6. Inspect the coverage — check the thickness and the uniformity

Preventing Roof Problems in San Clemente

• Check the waterproofing each spring — the winter rain reveals the gaps
• Check for the ponding water — the standing water degrades the membrane
• Use the corrosion-resistant flashing — the salt air eats the standard metal
• Recoat every 5 to 10 years — the membrane wears and needs the renewal

Expert tip: in San Clemente, the waterproofing is about the preparation. The surface needs to be clean and the cracks need to be patched before the membrane goes on. The prep work determines the life of the waterproofing.
