Remove Algae Streaks Without Damaging Your Shingles

Non-damaging roof cleaning services for homeowners in Lafayette, Louisiana.

You look up at your roof and see dark streaks running down from the ridge, and you wonder if it is time to replace the shingles. In Lafayette, those streaks are usually algae, not wear, and they show up on roofs that still have years of useful life left. The discoloration makes your home look older than it is, and if left untreated, the organic growth can hold moisture against the shingles and shorten their lifespan.

Roof washing removes algae streaks, moss, and organic buildup using methods that protect the integrity of your shingles. Freedom Exterior Services applies a cleaning solution designed to break down the growth without the high pressure that can dislodge granules or lift shingle edges. The process is aligned with manufacturer recommendations and focuses on restoring appearance while supporting the long-term health of your roof. The work is performed with care to avoid damage to surrounding property, including gutters, landscaping, and painted surfaces.

If your roof in Lafayette has visible streaks or moss growth and you want to understand what cleaning involves, Freedom Exterior Services can inspect the roof and explain what results are realistic given the current condition.

What Safe Roof Cleaning Actually Involves

The process begins with a roof inspection to identify the type of shingles, the extent of growth, and any areas that need special attention. In Lafayette, that often means addressing algae on north-facing slopes and moss in valleys or near tree lines. The crew applies a cleaning solution using low-pressure equipment, allows it to dwell, then rinses it away carefully to avoid forcing water under the shingles.

After the roof is cleaned, the dark streaks will be gone and the original color of the shingles will be visible again. The roof will look maintained rather than neglected, and the removal of organic growth helps prevent moisture retention that can degrade the shingles over time. The appearance improvement is immediate, and the roof will stay cleaner longer because the algae has been killed at the source.

The service includes clearing debris from gutters after the cleaning and rinsing landscaping to remove any runoff. It does not include shingle repair, replacement, or structural work. If the roof has missing shingles, damaged flashing, or leaks, those issues need to be addressed separately. Roof washing cleans the surface but does not fix underlying damage or extend the life of a roof that is already failing.

Questions Homeowners Ask About Roof Cleaning

Most people want to know whether roof cleaning is safe, how long the results last, and whether it will affect their warranty. These are the questions Freedom Exterior Services hears most often from homeowners in Lafayette.

Will roof cleaning damage my shingles?
Roof cleaning performed with low pressure and appropriate solutions will not damage shingles. Freedom Exterior Services uses methods that align with manufacturer guidelines to protect the granules and integrity of the roofing material.
How long will my roof stay clean after washing?
Your roof will typically stay clean for two to four years depending on shade, humidity, and nearby trees. Roofs with heavy shade or surrounded by foliage may see algae return sooner.
Can roof washing remove moss as well as algae?
Roof washing can remove light moss growth, but heavy moss may need to be manually loosened before cleaning. The crew will assess the roof and recommend the best approach based on what is growing and where.
Will cleaning my roof void the shingle warranty?
Cleaning your roof with approved low-pressure methods should not void your warranty. Freedom Exterior Services follows manufacturer recommendations and avoids high-pressure techniques that some warranties specifically prohibit.
What happens to the cleaning solution after it runs off the roof?
The crew pre-wets and rinses landscaping around the roofline to dilute any runoff. The cleaning solution breaks down quickly once exposed to soil and water, minimizing impact on plants and grass.

If your roof has dark streaks or visible moss and you want to restore its appearance without replacing shingles, Freedom Exterior Services can schedule an inspection to assess the condition and determine whether cleaning is appropriate.
