This comes up constantly, and the useful version of the answer is shorter than most of what is written about it. Here is how cool roofs and energy savings actually works for a homeowner in Beverly Hills, without the parts that exist to sell something.
What makes a roof cool
Ventilation is the quiet half of this: a sealed attic shortens any roof.
Two numbers: solar reflectance and thermal emittance. Together they give the Solar Reflectance Index that code references.
What it saves
Real savings on cooling load in a valley summer, and a meaningfully cooler attic, which extends the life of everything stored in it.
Where it is required
California Title 24 sets prescriptive requirements for many re-roof scenarios by climate zone.
The short version
- What makes a roof cool
- What it saves
- Where it is required
- Get it in writing, whatever it is
- Ask what happens if the assumption behind the price turns out to be wrong
None of this is complicated, but it is the sort of thing that is easy to skip when the roof is already leaking and the decision feels urgent. That urgency is exactly when the questions matter most.
On cool roof, two quotes can differ by thousands and both be honest - the scopes are different.
Questions we get asked
How much does cool roofs and energy savings usually cost?
It varies with scope more than with anything else, which is why a number quoted before anyone has looked at the roof is not a number. Get an itemized estimate.
How do I know the contractor is legitimate?
Check the license against the CSLB database yourself, ask for the workers compensation certificate, and confirm the permit is pulled in the contractor's name rather than yours.
Should I get more than one estimate?
Yes, and compare the scopes rather than the totals. Two estimates that differ by a third usually differ because one of them includes underlayment, flashing and deck repair and the other does not.
