Roof Maintenance Cost Calculator
Roof maintenance is the cheapest money you will ever spend on your house. Clearing gutters and fixing small leaks costs a few hundred dollars a year; ignoring them turns a $400 repair into a $4,000 one when water reaches the decking. This calculator estimates realistic annual upkeep for your roof.

How we calculated your estimate
Annual maintenance is driven by material and climate. We estimate gutter clearing, inspection and minor repair costs scaled to your roof size, adjusted for how demanding your material is — wood shake needs regular treatment, metal needs almost nothing.
Labor rates derive from published BLS occupational wage data. Read the full methodology →

Factors that affect the cost
Material
Metal needs almost nothing. Wood shake needs regular cleaning and treatment. Asphalt sits in between.
Climate & trees
Overhanging trees mean debris, moss and blocked gutters. A heavily treed lot can double your maintenance burden.
Roof size
Bigger roof, more gutter, more surface to inspect and clear.
Neglect
The most expensive factor of all. Deferred maintenance is the leading route from small problem to structural repair.
Ways to save money
Clear gutters twice a year, without fail
Blocked gutters send water back under the shingles and into the fascia. It is the single highest-return maintenance task there is.
Trim overhanging branches
Branches drop debris, hold moisture against the roof, and give squirrels a road in. Trimming is cheap; a rotted deck is not.
Fix small leaks immediately
A leak that reaches the decking turns a few-hundred-dollar repair into a few-thousand-dollar one. Water damage compounds.
Common mistakes to avoid
Pressure-washing an asphalt roof
It strips the granules that protect the shingle from UV. It looks better for a season and takes years off the roof.
Ignoring moss
Moss holds moisture against the roof surface and lifts shingle edges. In damp climates it is a genuine cause of premature failure, not a cosmetic issue.
Frequently asked questions
Typically $300–$800 annually — gutter clearing twice a year, an inspection, and budget for a minor repair. Wood shake costs more; metal costs very little.
Once a year, and after any major storm. An independent inspection costs $150–$400 and is not a sales pitch — which is exactly why it is worth paying for.
It is the highest-return spending on your house. A $200 gutter clean prevents water getting under shingles and into the decking, where a repair costs thousands.
Clearing gutters and removing debris, yes, with proper safety precautions. But never pressure-wash asphalt shingles — it strips the protective granules and takes years off the roof.
Use a purpose-made moss treatment, applied gently, and fix the underlying cause — usually shade and trapped moisture from overhanging branches. Never scrape or pressure-wash.
Meaningfully. Clear gutters, good ventilation and prompt small repairs can be the difference between an asphalt roof lasting 20 years and lasting 30.
