The three things that wreck roofs here
Heat, wind and neglect, in that order. A summer of days above a hundred degrees bakes the asphalt out of composition shingles and turns underlayment under tile brittle enough to crumble in your hand. Then the Santa Ana winds arrive in the fall and find every loose ridge cap and lifted tab.
Neglect does the rest. A roof that gets its gutters cleared and its flashings sealed every year lasts a long time in this climate. One that nobody looks at until the ceiling drips has usually been failing quietly for several winters.
What I offer
Inspections with a written report, repairs to any roof type, full replacements when they are warranted, storm response, gutter and debris service, and a yearly protection plan that handles the boring maintenance for you.
Commercial flat roofs are part of the work too, mostly shops and small industrial buildings between the 10 and the 210.
How I decide repair versus replace
I am looking at three things: is the underlayment still doing its job, is the deck solid, and is the damage local or everywhere. Local damage on a sound deck gets repaired. Failed underlayment across most of the roof means the surface material is no longer the problem and patching would be throwing money at a lost cause.
You get both scopes in writing when the answer is close, and I tell you which one I would pick for my own house.
Local roof types
Older neighborhoods around downtown San Bernardino and the west side carry a lot of three-tab composition shingle, some of it layered twice. The tracts built from the late 1970s on, especially toward Highland and north Rialto, are mostly concrete tile. Scattered through both you find shake that has been overlaid, and a few metal roofs on ranch properties.
Each one fails differently, and each one gets a different inspection route from me.
Start here
If you have a stain, a leak or a tile in the yard, use the contact page and describe it. If you just want to know where your roof stands, book an inspection in early fall before the first real rain.
