Henderson FAQ
Do I need a cool roof for my house?
No. Henderson cool-roof rules apply to low-slope commercial. Steep-slope and residential roofs are exempt but eligible for NV Energy and utility rebates if voluntarily installed.
What is solar reflectance index?
SRI measures how much sunlight a surface reflects rather than absorbs. Higher SRI means cooler surface temperatures, lower cooling loads, and reduced urban heat island contribution.
Las Vegas FAQ
Do I need a permit to reroof my house?
Yes. Las Vegas requires a roofing permit through the Department of Building and Safety. The contractor must select materials meeting IECC reflectance and submit product specifications for review.
Can I keep dark tiles for aesthetics?
Steep-slope homes have more flexibility. Some HOAs require specific colors. Work with your contractor to find tiles that match the neighborhood palette and still meet the solar reflectance index threshold.
