Choosing the Right Material for Your Property
The modern standard for energy efficiency. White reflective surface lowers cooling costs. Heat-welded seams provide superior leak protection. Best for large commercial or modern residential.
Also known as "Torch Down." Multi-ply durability perfect for high-traffic roof decks or older San Francisco buildings. Extremely tough and puncture-resistant.
Chemical resistant and highly durable. Ideal for restaurants or industrial buildings with grease/oil exhaust. Long-term performance in harsh environments.
The enemy of every flat roof is standing water. Unlike pitched roofs, flat systems must be engineered with precise slopes (1/4" per foot) to ensure drainage.
We install custom-cut foam insulation boards to create positive drainage on dead-flat decks.
Diverters built around chimneys and AC units to prevent water from getting trapped behind obstacles.
Enlarged drainage outlets and overflow scuppers to handle atmospheric river storm volumes.
Answers to Common Questions
A modern TPO or PVC roof typically lasts **20-25 years**. Modified Bitumen (Torch Down) roofs generally last **15-20 years**. Proper maintenance and drainage are key to maximizing lifespan.
It depends on the building. TPO is better for energy efficiency (white reflective) and large open areas. Torch Down is excellent for complex roofs with many penetrations (vents, pipes) and high foot traffic. We can recommend the best system for your specific property.
California Title 24 requires new flat roofs to meet certain solar reflectivity standards to reduce energy consumption. TPO and white-granular Torch Down caps sheets meet these requirements, helping keep your building cooler.
