The Roof Is Only Half the Question. The Other Half Is Where the Water Goes

Yes. Re-roofing a home in Highland requires a building permit through the city’s building department, and the work is inspected. That applies to a full composition tear-off and generally to a tile lift-and-relay too, since replacing the underlayment is replacing the roof system regardless of the tile going back on.

The inspection is the value in it. It is the only independent confirmation that the deck was repaired where needed, the underlayment went on to the manufacturer’s requirements and the flashing was replaced rather than resealed — none of which is visible to you afterwards. It also puts a dated record of the roof’s age and assembly on the property, which is useful at resale and increasingly with insurers. We file the permit at the start of the project rather than mid-job, so the inspection points and the build sequence stay in step.

Usually a sizing problem, and it is genuinely both. A gutter is a channel with a finite capacity, and the flow reaching it depends on the roof area feeding it, the pitch of that area, and the intensity of the rainfall. Highland sits at the mountain front where storm intensity runs higher than out on the valley floor, so a gutter section that is perfectly adequate a few miles west can be undersized here on the same house.

Overshooting matters beyond the nuisance. Water going over the front of a gutter lands at the base of the wall, which over years works on stucco, on the fascia above, and on whatever the ground does with it at the foundation. Water backing up behind a full or undersized gutter can also work back under the first course of the covering, which is where it becomes a roof leak. The fix is usually a larger section, more downspouts, or both — and it is worth doing at the same time as a re-roof because the access is already paid for.

Away from the building, and further away than most people assume. A downspout that empties at the base of a wall is putting a concentrated volume of water directly where you least want it — against the stucco, into whatever is planted there, and into the ground next to the foundation. In a mountain-front storm that is a lot of water arriving in a short time at one point.

The straightforward answers are an extension that carries the discharge clear of the building, a splash block onto a surface that drains away, or where the site allows it, tying into something that takes the water off the property properly. Which one suits depends on your grading, and the honest version of that conversation happens standing on the ground looking at where the water currently goes. It is also worth counting downspouts rather than assuming: a long run with a single downspout at one end is a common arrangement and a poor one, because the far end of the gutter has to carry the entire flow to reach it.

That pattern almost always points at capacity rather than at a hole. A valley collects the flow from the two planes either side of it and carries it down to the eave. In light rain the volume is small and the valley handles it comfortably. In an intense storm the same valley is moving several times the flow, the water depth in it rises, and it can rise above the lap of the covering at the edge of the valley — at which point water goes sideways under the tile rather than down the valley.

It is a construction and sizing issue, and it shows up most on roofs where two large planes drain into one valley, which is common on the bigger tract plans. The correction is a wider valley metal, a different valley construction, or in some cases changing how the tile is cut and set at the valley edge so the water has less opportunity to get across it. A repair that just seals along the valley will not address it, because nothing was leaking through a hole in the first place.

The covering follows the usual drivers: area, pitch, assembly, layer count, deck condition and roofline complexity. The drainage is the additional line here — valley construction sized for the planes feeding it, gutter section and downspout count matched to the roof rather than inherited from whatever was on the house, and discharge routed properly.

That drainage work is a modest share of a re-roof and it is the part most likely to prevent the next problem, which is why we price it separately rather than absorbing it. It also means you can see the choice: if the covering has life left, doing the drainage on its own is sometimes the right call. Californian roofing runs above the national average on labour and materials and the state’s licensing requirements.

Yes. CSLB #1105333 is a Class B General Building licence, which covers the roof and the trades a water problem actually damages. On a Highland house that frequently means stucco at the base of a wall where a gutter has been overshooting for years, fascia above it, and the interior drywall and paint where a leak has come through.

The reason it matters to have it under one licence here is that the cause and the damage are often in different trades. Fixing the roof without fixing the drainage leaves the stucco to keep taking water; repairing the stucco without fixing the drainage means doing it again. Following the water from the ridge to the ground and repairing everything it touched is one project when one contractor is answerable for all of it, and three phone calls otherwise. Free roof inspection, and financing if the full scope is larger than you planned for.
