Roof Waterproofing in Pico Rivera, California

The Pico Rivera winter rain can be heavy, and the flat roofs on the commercial and the apartment buildings are the most vulnerable. Roof waterproofing in Pico Rivera seals the roof surface against the rain and the standing water.

Signs Your Pico Rivera Roof Needs Waterproofing

• Ponding water after a rain — the water sits on the roof for days
• Leaks during the winter rain season — the water finds the cracks
• Blisters and bubbles on the membrane — the moisture is trapped under the surface
• Cracked sealant around the drains and the flashings — the water gets in at the edges
• The roof is over 15 years old — the waterproofing has worn out

Why Pico Rivera Roofs Need Waterproofing

The LA Basin rain is seasonal and can be heavy. The flat roofs on the commercial and the apartment buildings pool the water, and the standing water finds the weak points.

The waterproofing membrane seals the roof surface. The water runs off the drains, and the roof deck stays dry.

How We Waterproof Roofs in Pico Rivera

1. Inspect the roof — find the cracks, the blisters, and the weak seams
2. Clean the surface — pressure wash the dirt and the debris
3. Repair the damage — patch the cracks, replace the damaged membrane
4. Apply the waterproofing — liquid membrane, sheet membrane, or coating
5. Seal the flashings and the drains — the edges are the vulnerable points

Preventing Roof Problems in Pico Rivera

• Check the drains before the winter rain — the debris blocks the drainage
• Inspect the seams and the flashings — the edges fail first
• Clear the ponding water — the standing water ages the membrane faster
• Schedule a fall waterproofing check — catch the weak spots before the rain

Expert tip: in Pico Rivera, the waterproofing work peaks in the fall. The window before the winter rain is the time to seal the roof.
