10 Signs Your Roof Needs a Moss Makeover – Don't Miss #7!


Your roof is a vital part of your home’s protection against external elements. However, over time, it may become susceptible to moss growth, which can cause numerous issues if left untreated. Identifying the signs that your roof needs a moss makeover is crucial to maintaining its longevity and functionality. In this article, we will discuss ten telltale signs that your roof requires immediate attention. Make sure you don’t miss out on the seventh sign, as it can have significant implications for your roof’s health!

1. Excessive Shade

If your roof is situated in a predominantly shaded area, it is more likely to develop moss growth. Moss thrives in moist and cool environments, making shaded rooftops perfect breeding grounds. Look out for patches of dark green or black vegetation, as this may indicate the presence of moss.

2. Damp or Moisture Retention

Moss tends to retain moisture, and if your roof holds water after rain showers or exhibits signs of prolonged dampness, it could be a sign of moss accumulation. Examine your roof for areas where water seems to collect or if you notice moisture seeping through your ceiling.

2.1 Water Pooling

One specific sign of excessive moisture retention is water pooling on your roof. If you notice standing water after rainfall or areas where water accumulates, it may be an early indication of moss growth. Addressing this issue promptly will prevent further damages to your roof.

2.2 Leaks and Water Stains

Moss can deteriorate your roof’s protective layers, leading to leaks and water stains inside your home. Keep an eye out for discolored spots or watermarks on your ceilings or walls, as this may point to an underlying moss problem.

3. Accelerated Roof Aging

A roof with an excessive growth of moss often appears older than it actually is. Moss can cause premature degradation of roofing materials, such as asphalt shingles or tiles. If your roof looks noticeably aged, brittle, or worn out compared to its expected lifespan, moss may be to blame.

4. Visual Distortion

Moss growth on your roof can cause it to look irregular or distorted. The presence of lumps and bumps can be a clear indication of moss accumulation. If you notice any of these visual irregularities, it’s essential to address them promptly to maintain the aesthetic appeal of your home.

5. Damaged Gutters and Downspouts

Excessive moss growth on your roof can clog gutters and downspouts. Debris accumulated from decaying moss can obstruct the proper flow of water, leading to water backups and potential gutter damage. Regularly inspect your gutters for signs of moss buildup to prevent these issues.

5.1 Overflowing Gutters

Overflowing gutters during rainfall can indicate moss accumulation. When water cannot flow freely through clogged gutters due to moss and debris, it can spill over the sides, causing potential damage to your home’s foundation or landscaping.

5.2 Sagging Gutters

Moss-filled gutters can become heavy, resulting in sagging or detached sections. This compromises their functionality and may require costly repairs or replacements. Keeping your gutters free from moss is crucial to avoid such issues.

6. Loss of Granules

Moss growth can cause the loss of granules from your roofing materials. If you find an excessive amount of granules in your gutters or if your roof looks bare in certain areas, it might signify that moss has taken hold and caused damage to the protective layer of your roof.

6.1 Granule Accumulation

Inspect your gutters for an accumulation of granules mixed with moss or clogged within the moss itself. This is a strong indicator that your roof is in need of a moss makeover, as the loss of granules can accelerate the deterioration of your roofing materials.

7. Animal Infestation

One crucial sign not to miss is the presence of animals on your roof. Moss provides a habitat for small critters, such as rodents or insects, which can cause further damage to your roof and compromise its integrity. If you spot any signs of animal activity, it’s essential to address the moss problem promptly.

8. Peeling or Curling Shingles

Moss can lift shingles or cause them to curl due to its persistent moisture-retaining qualities. If you observe any shingles that appear warped, bent, or raised, it could be a result of underlying moss growth, and immediate action should be taken to rectify the situation.

9. Weakened Structural Integrity

Prolonged moss growth can weaken the structural integrity of your roof. If you notice any sagging or dipping sections on your roof or if it feels unstable when walking on it, it could be a sign of significant damage caused by moss. Professional assistance should be sought to prevent further deterioration.

10. Reduced Energy Efficiency

Moss-covered roofs can hinder your home’s energy efficiency. Moss prevents sunlight from properly reflecting off your roof’s surface, leading to increased heat absorption and potential temperature imbalances within your home. A moss makeover can help restore your roof’s energy-saving capabilities.


Identifying the signs that your roof needs a moss makeover is crucial to ensuring its longevity and structural integrity. From excessive shade and moisture retention to visual distortions and weakened structural integrity, familiarizing yourself with these indicators will help you address roof moss issues at the earliest possible stage. Don’t forget to pay special attention to the presence of animals on your roof and the potential consequences of moss on your gutters. By taking timely action, you can maintain a moss-free roof and protect your home from further damages. So, be proactive and don’t overlook the seventh sign, as it may be the key to preserving the health and appearance of your roof.
