Built Into a Slope, With Roofs at Three Different Heights

Because that junction is doing more work than any other part of the roof and it is usually detailed as though it were doing less. An upper roof collects water across its whole area and delivers it in a concentrated stream to the point where it meets the wall below. The flashing there has to handle that volume, and it has to be integrated into the wall covering rather than sitting on top of it.

In winter it gets worse. Snow shed or sliding off the upper roof piles against that same wall, then melts slowly over days, which means standing water and saturated snow sitting directly against a junction for extended periods rather than running past it. Very little flashing survives that treatment if it was installed as a rain detail. The durable fix is a properly built step and wall flashing, integrated behind the wall covering, plus managing what arrives from above — retention on the upper slope, or a diverter designed as part of the system rather than added to it.

They should be part of the conversation even if they are not part of the scope, because on a stepped hillside house the deck connections are one of the main ways water gets into framing. A deck ledger bolted to the house sits directly in the path of water coming off the roof above it, and if the flashing over that ledger was done poorly or has failed, water runs behind the ledger and into the wall framing where nobody sees it.

The practical problem is trade boundaries: roofers quote roofs, deck builders quote decks, and the flashing between them is the seam where responsibility gets vague. Because our licence is Class B General Building, roofs, deck structure, ledgers and the flashing that joins them are all things we can price and do. Whether you want the decks in the job is your call. What we would not do is replace a roof above a deck ledger that is visibly failing and say nothing about it.

San Bernardino County Land Use Services, because Twin Peaks is unincorporated rather than part of an incorporated city — the same as most of the Rim communities. Where the scope extends into deck structure or framing repair, that can carry its own review requirements beyond a straightforward covering replacement, and it is confirmed for the specific job rather than assumed.

The area is also in a fire hazard severity zone as a forest-adjacent mountain community, which bears on the assembly and its venting. All of that is established for your parcel during the estimate rather than surfacing later, because on a hillside house with a short working season an unexpected approval is an expensive kind of delay. The permit is filed at the start so the inspection points line up with the build sequence rather than extending it.

It is a cost and a planning item rather than an obstacle, and it should be settled before the price is agreed. On a house built into a slope, material frequently has to be moved by hand from wherever a truck can stop to wherever the work is, and debris has to come back the same way. That is real labour, it is predictable, and it belongs in the estimate.

What causes trouble is a contractor who quotes from a plan or an aerial view, treats the site as though it were flat, then meets the actual approach on the first morning. At that point the options are asking for more money or rushing, and neither is good for you. We walk the access on the first visit, including which levels are reachable and from where, and price what is actually there. On some Twin Peaks lots that assessment is the largest single variable in the job.

The area of covering is often the smaller part of the answer. A stepped house with three roof levels has more perimeter, more flashing and more junctions per square foot than a single-plane roof of the same total size, and the junctions are where the skilled labour goes. Access adds handling. The mountain assembly — eave protection, ventilation, Class A fire performance — is real material and work.

Then there is what gets found. On these houses, framing damage at a step junction or behind a deck ledger is common rather than exceptional, so we price deck and framing repair in the written estimate rather than leaving it open. Californian roofing runs above the national average on labour, materials and the state’s licensing and permitting requirements. Free inspection of every level and junction, financing available, 15% remodeling coupon running.

Yes, and on a hillside house that is usually where the actual damage is. CSLB #1105333 is a Class B General Building licence, covering wall and roof framing, sheathing, deck structure and ledgers, and the interior finish, alongside the covering itself.

That breadth matters here because a leaking step junction damages things in three different trades at once — the roof above it, the wall framing behind it, and often the deck attached nearby. A roofing contractor can stop the water and legitimately leave the framing to somebody else, but the framing is the part that determines whether the house is sound. Under one licence the whole junction gets rebuilt as one piece of work, and the person who diagnosed it is the person who fixes it. Free roof inspection, and financing available if the full scope is more than you planned to fund at once.
