Condition, scope & system planning
Maintenance should protect the roof without damaging the covering, finish, flashings, fasteners, or warranty
Routine roof care can identify small problems before they become interior leaks. Useful checks include debris, gutters, valleys, sealants, exposed fasteners, pipe boots, flashings, broken tiles, lifted shingles, corrosion, and tree contact.
Algae, lichen, moss, stains, and organic debris should be evaluated by roof type. Aggressive pressure washing, harsh chemicals, walking, or scraping can damage shingles, tiles, coatings, seams, or protective finishes.
The cleaning method should follow roofing material and manufacturer guidance. Runoff, landscaping, pools, metals, painted surfaces, gutters, and nearby property need protection.
Maintenance records, photographs, invoices, and warranty requirements can be valuable when tracking recurring conditions or documenting the roof over time.
Schedule may depend on tree cover, coastal exposure, debris, roof design, drainage, building use, and recent storms rather than a fixed annual rule.

Questions homeowners often ask
Should asphalt shingles be pressure washed?
High-pressure washing can remove granules and damage shingles. Use methods appropriate for the specific roof material and manufacturer guidance.
Does algae mean the roof is leaking?
Not necessarily, but biological growth can retain moisture and affect appearance. A separate inspection is needed to evaluate roof condition.
How often should a roof be inspected?
Frequency depends on age, material, tree cover, exposure, warranty, leaks, and storms. Many owners schedule periodic and post-storm checks.
