Reflective systems for low-slope roofs, and Title 24. Reflective systems in West Hills, specified to the Title 24 figure that actually applies to your slope.
Free inspection, the deck and layer count established, then a written quote.
Most West Hills roofs are pitched and tiled, so the low-slope requirement reaches only the additions and garages. Coating a tiled main roof to meet an energy requirement that does not apply to it is money spent for nothing.
California's Title 24 energy code sets reflectance and emittance requirements for many re-roofs, and a low-slope roof in Climate Zone 9 is squarely in scope. Meeting it is not optional, and it is much cheaper to plan for than to retrofit.
Silicone and elastomeric systems run $2.50 to $7.00 per square foot installed in California. Coating a sound low-slope roof is the cheapest way to meet the cool-roof requirement - full cool roofing runs $4 to $12 per square foot depending on the material. West Hills is where the relay saves the most money in this market, because it is where most of the tile is. It is also partly inside the zones CAL FIRE redrew Very High in 2025, and a Chapter 7A fire-rated assembly adds roughly $1 to $5 per square foot - about 22% - on a re-roof there.
10, 15 and 20 year systems are different products at different prices. Ask which one you are being quoted.
Coating over trapped moisture seals the problem in. We establish the condition underneath first, and will say so if coating is the wrong answer.
Low slope is required statewide. Steep slope applies in climate zones 10 to 15 and Los Angeles is in 6, 8 and 9 - so a pitched roof here is generally exempt. A quote charging for it on a pitched roof is worth questioning.
Concrete tile is heavy, and the part that fails is almost never the tile. It is the underlayment beneath it, which has a far shorter life than the tile it is protecting. A roof that looks perfect from the street can be past due.
All roofing work in West HillsMost homes lost to wildfire are ignited by embers rather than the fire front, and the roof is the largest surface an ember can land on.
Open ridge and eave ends, unscreened attic vents, and gutters packed with dry leaves. Embers find the gaps, so the details around the covering matter as much as the covering itself.
Every slope is photographed before and after and the set is yours. Every price is against a written scope that names the detail, so the rating and the closures are on paper, not promised at the door.
On a tile roof, and a lot of West Hills is tile, the leak is almost never the tile.
Much of West Hills is newer than its neighbors, with substantial 1980s to 2000s tracts along the Valley Circle and Sherman Way corridors.
West Hills has more tile than anywhere else we work, most of it on tracts built from the 1980s on.
Newer West Hills tracts tend to have smaller low-slope areas - a porch roof, a garage, a bay - tied into a tiled main roof.
Where West Hills is shingle rather than tile it is usually the newer tracts, which means architectural laminate rather than three-tab.

The questions that decide a job, answered before you ask.
It depends entirely on slope. Low slope is required statewide. Steep slope applies in climate zones 10 to 15, and Los Angeles is in 6, 8 and 9 - so a pitched roof here is generally outside the requirement. If someone is charging you for it on a pitched roof, ask which climate zone they think you are in.
Aged solar reflectance index, and for low slope the figure to clear is 75 or higher. Ask for it in writing - initial reflectance is a different and more flattering number, and a product with no aged SRI has not been tested for this.
Often you do not. On a tile roof the tile is usually fine and only the underlayment has failed, which is a lift and relay at roughly half the cost of replacing. If that is what your roof needs, that is what we will quote - and we will show you the felt to prove it.
In the highest-risk fire zones it is what California's wildfire building standards call for, and on the hill side of the Valley it is worth asking for either way. The quote names the rating of the whole assembly, not just the covering, plus the vent screening and the ridge and eave closures.
For a full replacement in LA County, an estimated $10,000 to $25,000 covers most houses, and repairs usually run an estimated $350 to $1,500. The honest answer is that the range is wide because pitch, access, covering and what the old roof was hiding all move it - which is why the inspection is free and the quote is written down before any work starts.
