Composition shingle, and what the sun does to it. Composition roofs across West Hills, including wind damage that is invisible from the ground.
Free inspection, the deck and layer count established, then a written quote.
Where West Hills is shingle rather than tile it is usually the newer tracts, which means architectural laminate rather than three-tab. Those fail differently: less granule loss, more seal-line failure and wind lift along the rakes.
Composition shingle is the most common covering in the Valley and the one the climate is hardest on. Ultraviolet light drives the volatiles out of the asphalt, the mat goes brittle, and the granules that were protecting it wash into the gutter.
Composition repairs run $350 to $1,500 in Los Angeles. Where a whole slope has gone, replacement is $7 to $11 per square foot - and on this housing stock a slope does tend to finish all at once rather than in patches. 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.
A creased shingle drops back flat and looks intact. Caught now it is a repair; found in January it is a ceiling.
We will tell you honestly which one you have. A bald section usually means the slope is finished, not damaged.
Two layers is the practical legal limit. If you are already at two, the next job is a tear-off whatever anyone quotes.
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.
A Class A roof assembly carries the highest fire rating a roof can have, and in the highest-risk fire zones it is what California's wildfire building standards call for. On the hill side of the Valley it is the rating worth asking for either way.
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.
Most West Hills roofs are pitched and tiled, so the low-slope requirement reaches only the additions and garages.

The questions that decide a job, answered before you ask.
Yes, and it is a cheap check. Santa Ana damage is close to invisible from the ground - the shingle creases at the seal line and drops back flat. It leaks in the first driving rain after, which can be months later when nobody connects the two.
Be careful what that tells you. Composition here tends to finish across a whole slope at once rather than in patches, so a bald section usually means that slope is done. We will tell you which one you have rather than selling you a patch that fails.
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.
Free inspection, written quote, and we will tell you if the cheaper option is the right one.
