Premium roofing materials — clay tile, natural slate, standing-seam metal — are 50-to-100-year systems. The 30-year view of their maintenance is more useful than the year-one view, because year-one is uneventful and year 30 reveals which roofs were maintained and which were not.
Here is the maintenance program we offer and what it covers across the lifespan.
Year 1: Establish the baseline
- 30-day inspection (included in project price)
- 6-month inspection (included in project price)
- 12-month inspection (included in project price; begins the annual cycle)
The first year is the most-attended period in a roof's life. We are establishing the baseline against which all future inspections will compare.
Years 2-10: Annual inspection cycle
- Annual visual inspection (ground walk + drone, $250-$450)
- Light maintenance (gutter cleaning, valley debris removal, $150-$300)
- Fastener inspection at year 5 (sample of accessible fasteners, $300-$500)
Light maintenance prevents the small accumulations that lead to larger problems. Annual inspections catch any drift in roof condition before it becomes critical.
Years 10-25: Mid-life inspection cycle
- Annual visual inspection (continues)
- Light maintenance (continues)
- Year 10 fastener inspection (broader sample, $400-$700)
- Year 15 underlayment inspection at sample locations ($600-$1,200, requires lifting small areas of field material)
- Year 20 flashing assessment (visual + selected probe, $400-$700)
The mid-life inspections catch the silent failure modes — fastener corrosion, underlayment edge wear, flashing sealant aging — that the visible field does not show.
Years 25+: Late-life inspection cycle
- Annual inspection (more thorough)
- Year 25 underlayment assessment with documented decision: replace at year 30, defer to year 35, or replace immediately
- Year 30+ depending on assessment: planned underlayment replacement, with field material reset
The underlayment is the single largest replacement item over the roof's life. Clay tile and slate fields can be reset on new underlayment; the field material itself does not need replacement.
What this costs over 30 years
Approximate cumulative cost of full maintenance program over 30 years on a typical 4,000 sq ft tile or slate roof:
- Annual inspections: $250-$450 × 30 = $7,500-$13,500
- Light maintenance: $150-$300 × 30 = $4,500-$9,000
- Mid-life targeted inspections: roughly $2,500-$4,500 cumulative
- Year 30 underlayment replacement: $25,000-$45,000
Total over 30 years: roughly $40,000-$72,000 in maintenance and the major underlayment refresh.
For comparison, the same roof completely replaced at year 30 (because it was not maintained): $180,000-$320,000.
The maintenance program extends the roof's life by 25-50 years on a $200,000-$300,000 initial investment for the cost of one substantial annual line item.
Who we put on the program
Almost all of our clients. The default at handover is enrollment; we ask the client to opt out rather than opt in.
About 75% of our clients stay on the program through year 5. About 60% remain through year 10. The clients who fall off are typically owners who sell the home before then — the program does not transfer to a new owner unless they renew.
What the program is not
The program is not extended warranty. The contractor's workmanship warranty (10 years) and the manufacturer's product warranty (50-75 years on premium materials) are separate from the maintenance program.
The program is preventive maintenance. The warranties are for defect-driven failures.
Why we offer this
The roofs we install are designed to last decades. The maintenance program is how the design intent is realized. A roof that is inspected annually and maintained on schedule reaches its design life. A roof that is ignored does not.
The program is also good business for us. Maintenance clients become long-term relationships; long-term relationships produce referrals; referrals are how a quiet practice grows.
The math works for everyone. The owner gets the longest possible life from the roof. We get the longest possible relationship with the property.
