Weather-impact guide
Identify where San Diego roofs most often fail during storm sequences: flashing transitions, valleys, tile movement, drainage bottlenecks, and wind-driven water intrusion paths.
Quick answer
Flashing joints, valley intersections, roof-to-wall seams, drain entries, and displaced tile edges are common failure origins during high-pressure rain windows.
Intent support: cost
When you can label the failure pathway first, quote comparisons become cleaner on the cost page and avoid under-scoped bids.
Interactive weak-point scanner
Set your home profile and storm stress levels to see directional weak-point priority. Use this to shape inspection scope before estimates.
Top weak point right now: Flashing transitions. Route to cost once this zone has a defined repair/replacement scope.
Multimedia intrusion model
Water pushes laterally under lifted edges and flashing terminations, then tracks to deck seams before appearing indoors.
Focus inspection at roof-to-wall transitions, counterflashing laps, and vent/pipe flashings first.
Weak-point matrix
Use this table to define inspection scope before comparing bids, then continue to the cost page for price ranges by scope depth.
| Weak point | Typical storm trigger | Cost impact pattern |
|---|---|---|
| Roof-to-wall flashing | Counterflashing laps and sealant fatigue | Localized repair if early; larger scope if deck wet |
| Valleys | Debris choke + water concentration | Valley rebuild and adjacent underlayment correction |
| Tile fields | Tile shift or cracked units opening pathways | Selective reset can work unless repeated movement exists |
| Drain/scupper entries | Backflow and overflow during bursts | Drainage correction often lowers recurrence risk |
| Prior patch interfaces | Old repairs with incompatible sealants | Frequent hidden source of repeated interior staining |
