Got an HOA Letter About Dirty Siding or Roof?

What does an HOA violation letter for dirty siding or roof mean?

An HOA violation letter citing stained, discolored, or "unsightly" siding, roofing, or walkways means the association's exterior maintenance standard has been triggered by algae, mildew, or oxidation visible from the street. It is a cure notice: the homeowner has a set period, commonly 14 to 30 days, to fix the condition before fines begin. One professional cleaning visit clears it.

What is the association actually enforcing?

Every planned community operates under a declaration of covenants, conditions, and restrictions, the CC&Rs, plus a set of rules and architectural standards. Somewhere in those documents is a clause requiring owners to keep exterior surfaces "clean," "well maintained," or "free of mildew, stains, and discoloration." The letter quotes that clause.

The inspector is not measuring anything. Violations are called from the street or sidewalk on the basis of what is visible: a green cast on the north wall, dark vertical runs on the roof, black walkways, a fence that has gone gray-green. Because the standard is visual, the fix is visual too. Once the surfaces look clean from where the inspector stood, the violation is cured.

Most notices follow a standard sequence. The first letter is a courtesy notice or warning with a compliance date. If nothing changes, a second letter sets a hearing or begins daily or weekly fines. Continued non-compliance can lead to the association hiring a contractor and billing the owner, or in some communities placing a lien. None of that happens if the first letter is answered within the cure period, which is why the date on page one matters more than the tone.

In New Jersey, associations generally must give written notice and an opportunity to be heard before imposing fines, so a homeowner who disagrees with the finding can request a hearing. In practice, on a cleanliness citation, cleaning is faster than arguing.

Step 1: Read the letter for the three things that matter

Set aside the boilerplate and find the finding, the deadline, and the proof.

The finding is the specific condition cited. Letters vary from precise ("mildew on north elevation siding; algae staining on front walkway") to vague ("exterior requires cleaning"). If the letter is vague, call the management office and ask exactly what was flagged and from where. Cleaning the wrong surface does not clear the violation. Common findings and what they almost always are:

• "Discoloration" or "green/black staining on siding." Algae and mildew on vinyl, aluminum, or fiber cement, heaviest on the north and east walls and under eaves.
• "Roof staining" or "streaks on roof." Gloeocapsa magma algae feeding on the limestone filler in asphalt shingles, running down the slope from the ridge.
• "Walkway/driveway staining." Black algae and mildew on concrete or pavers, sometimes with rust from sprinklers or leaf tannin stains.
• "Fence discoloration." Green algae on white vinyl fencing or gray-green growth on wood.
• "Gutter staining." Black tiger stripes on gutter faces, which are oxidation and overflow residue.

Next comes the deadline, the compliance date, which should be treated as firm. Note whether the letter asks for the work to be completed by that date or merely scheduled, since some associations accept a contractor's confirmation as good faith. If the date is tight and weather is a factor, a call to the management office before the deadline, not after, usually buys an extension.

Last is the proof: what the association wants to see afterward. Some require a written response, some re-inspect automatically, some ask for photos. Knowing this on day one saves a second letter.

Step 2: Match the fix to the finding

Each cited surface has a correct cleaning method, and using the wrong one either fails to clear the growth or damages the surface.

Siding is soft-washed. Algae and mildew are killed by a biodegradable cleaning solution applied at low pressure, under 500 PSI, allowed to dwell, then rinsed. High pressure on vinyl forces water behind the panels and etches aluminum; it also leaves the roots of the growth in place so the green comes back within weeks. A full house exterior takes four to six hours.

Roofs are soft-washed as well, never pressure washed. The same class of solution kills the algae on contact, and streaks fade over the following 24 to 48 hours as rain rinses dead growth away. Pressure on shingles strips granules and voids the manufacturer's warranty, which is a second problem the association will notice.

Walkways, driveways, and patios are power-washed with heated water at pressure suited to concrete or pavers. Rust and oil need a pre-treatment before the wash. Pavers with sunken or missing joint sand can be re-sanded in the same visit.

Fences and decks get low pressure and the appropriate cleaner for vinyl or wood. Gutter faces need a dedicated oxidation remover and hand work; a rinse alone does not remove tiger striping.

Booking these together is the efficient move. A single visit can cover the siding, roof, walkway, and gutter faces cited in one letter, with landscaping pre-wetted and protected once. The order runs top to bottom: roof, then gutters and siding, then hard surfaces last, so runoff never lands on a surface already cleaned.

Step 3: Close out the violation and keep it closed
