The visible surface signs (1–6)
Curling or cupping shingles: edges turning up or centers sagging — the classic end-of-life signal. Cracked shingles: thermal cycling has made them brittle. Missing shingles after moderate wind: seals have failed.
Bald spots and granule loss: check your gutters — granule piles mean the protective surface is washing away. Moss or algae colonization: holds moisture against shingles and accelerates decay. Daylight through the attic deck: the unmistakable ‘it’s time’ signal.
The structural and age signs (7–9)
Sagging deck areas between rafters: structural compromise, often from long-term moisture. Widespread flashing failure: when every joint is failing, the system is done. Age past 20–25 years for shingles (15–20 in harsh CA sun): even good-looking roofs this old are living on borrowed time.
Multiple active leaks at unrelated points: not bad luck — systemic failure. Repairing the third while the fourth brews is the definition of good money after bad.
The economic signs (10–12)
Repair bills approaching a third of replacement cost on an aging roof. Energy bills climbing as ventilation and insulation underperform. A sale or refinance on the horizon — appraisers and buyers mark down failing roofs hard.
Any two of these together mean it’s planning time. Any four mean it’s past planning time.
