Types Of Roofs We Clean

We specialize in cleaning a variety of roof types with techniques tailored to their unique materials and structures. Each type requires specific care to maintain integrity and extend lifespan.

1. Tile Roof Cleaning


Tile roofs, made from clay or concrete, are durable but prone to moss, algae, and dirt buildup. We use soft washing methods to gently remove debris without damaging the tiles or dislodging them.


Our approach includes careful inspection of broken or loose tiles before cleaning. We apply eco-friendly cleaning solutions that inhibit future growth of moss and algae. This method preserves the color and texture of the tiles while improving your roof’s appearance.



2. Asphalt Shingle Roofs


Asphalt shingles are common and vulnerable to mold, algae, and granule loss. We avoid high-pressure washing, which can strip shingles and lead to premature wear.


Instead, we use low-pressure cleaning combined with specialized treatments to kill algae and moss at the root. This approach reduces damage risks and extends the shingles’ effective life.


We also clear gutters and examine shingles for signs of curling, cracking, or other damage during cleaning.




3. Flat and Low-Slope Roofs


Asphalt shingles are common and vulnerable to mold, algae, and granule loss. We avoid high-pressure washing, which can strip shingles and lead to premature wear.


Instead, we use low-pressure cleaning combined with specialized treatments to kill algae and moss at the root. This approach reduces damage risks and extends the shingles’ effective life.


We also clear gutters and examine shingles for signs of curling, cracking, or other damage during cleaning.

Signs Your Roof Needs Cleaning

We recognize several clear indicators that show when a roof requires cleaning. These signs can affect the roof’s lifespan and appearance, so attention is essential.

Visible Algae or Moss

One of the most common signs is the presence of algae or moss growth on the roof surface. Algae often appear as black or green streaks, primarily on shaded north-facing slopes where moisture lingers.


Moss growth occurs in clumps and can trap water, potentially causing shingle damage over time. Both algae and moss retain moisture, which accelerates roof deterioration.


Regular inspection for these growths helps us determine when cleaning needs to happen, reducing the risk of structural issues and keeping the roof looking well-maintained.

Staining and Discoloration

Stains and discoloration often show up as dark patches or uneven color on roof shingles. This is usually caused by dirt, pollution, mold, or fungi buildup.


Such staining not only affects curb appeal but can indicate moisture retention that harms the roofing material. We prioritize cleaning when these stains appear to maintain the roofing system’s integrity.



Left untreated, discoloration can lead to premature aging of the roof and may reduce its protective capabilities against the elements.

Debris Accumulation

Leaves, pine needles, branches, and other debris collecting on the roof can block drainage and trap moisture. This accumulation can promote wood rot and increase the risk of leaks.



Debris in gutters can cause water backup, which may damage the roof edge and fascia. We recommend periodic removal to prevent these issues.


We also look for clogged valleys and gutters, as these areas tend to accumulate debris and require thorough cleaning to ensure proper water flow.

Frequently Asked Questions

In Glendale’s warm, sunny climate, roofs quickly collect dust, pollen, and organic growth that can shorten their lifespan and hurt curb appeal. These FAQs cover what to expect when hiring Glendale Elite Roofing for professional roof cleaning in Glendale, CA—so you can make the right choice without any guesswork.

  • How often should I have my roof cleaned in Glendale, CA?

    In Glendale’s dusty, sun-baked environment, we recommend roof cleaning every 2–3 years. If you notice black streaks, green algae, or granule buildup sooner, schedule a cleaning sooner—especially under oak trees or near landscaped areas that drop leaves and debris.

  • Will roof cleaning extend the life of my roof?

    Yes. By eliminating algae and moss that trap moisture, our soft-wash cleaning helps prevent shingle deterioration, rot, and leaks. In Glendale, where rainstorms can follow extended dry periods, keeping shingles clear of organic growth means fewer repairs down the road and a roof that lasts longer.

  • Can I walk on my roof right after cleaning?

    We recommend waiting at least 24 hours after our soft-wash process to allow shingles to fully dry and cleaning agents to rinse away. Once dry, shingles are safe to walk on. We’ll notify you when it’s okay to venture up for any repairs or inspections.

  • Do you offer any guarantees or warranties?

    Yes. Glendale Elite Roofing stands behind our work: if any algae or black streaks return within 12 months of cleaning, we'll re-clean those areas at no additional charge. This guarantee applies only if no roof repairs or new debris sources (like dropped sap or heavy leaf cover) are introduced.

  • What if I notice stains or growth on my roof again after cleaning?

    Minor algae spots can reappear over time. Glendale Elite Roofing offers an annual maintenance check (at a discounted rate) to spot-check for regrowth. If you see recurrence within six months, we’ll return and touch up those areas at no extra labor charge—only the cost of materials.
