Energy Code Compliance

All recommendations meet ASHRAE 90.1 standards, and California Title 24 energy code requirements for new construction or retrofit projects. Verified computer modeling simulations analyze options.

Material Selection Considerations

Solar Reflectance Index (SRI):

Higher values reflect more sunlight, lowering roof temperatures and AC usage. Materials undergo rigorous SRI testing by a CA-licensed lab.

Emissivity:

Materials’ innate ability to release absorbed heat as infrared radiation. Ceramic-coated metal and modified bitumen options have very high emissivity expelling heat effectively.

Insulation Value (R-Value):

Added roof insulation below the decking improves overall assembly R-Value, reducing heat transfer into conditioned spaces and requiring less energy usage. Options range from R-19 to R-38.

Airtight Installation:

Properly sealing roof penetrations and ensuring underlayment/deck joints do not compromise air barrier integrity is crucial for maximizing attained R-Values and minimizing air infiltration/exfiltration.

Cool Roof Material Options:

Energy Star® Rated Metal Roofing:

– Durable steel options with factory-applied solar-reflective paint coatings

– Lifetime SRI values range from 85-110

Modified Bitumen Membranes:

– Thermoset or thermoplastic formulations with ceramic-based UV-resistant surfacing

– SRI 65-95, built-in insulation providing R-values up to R-7.4

TPO & PVC Single-Ply:

– Heat-welded seams create fully adhered, monolithic membranes

– White surfaces standard with SRI over 82 and reflective options SRI 105+

Green Roof Systems:

– Engineered assemblies raising the roof deck above the structure on waterproofed trays

– Planted with drought-resistant flora naturally cooling surrounding spaces
