A roof is one of the most crucial components of a building, yet it often goes unnoticed until a problem arises. Neglecting the health of your roof can lead to costly repairs and structural damage. Therefore, keeping an eye on such issues, as well as getting help from professionals to get instant repairs, is a must to increase the longevity of your roof.

In this blog, we explore the seven most crucial warning signs that indicate your roof might need some TLC (Tender Loving Care). Whether you are a mature homeowner or a first-time buyer, understanding these important signals can save you time, money, and stress in the long run. Let’s dive in:

7 Signs of an Unhealthy Roof

Here are the 7 most important signs of an unhealthy roof:

1. General Roof Leaks

Roof leaks are the most common issue that leads to roof repairs. As a result, few take them seriously but do remember that even minor roof leaks can cause significant damage to your property over time. Therefore, repairing roof leaks should be the number one priority of homeowners.

Repairing roof leaks immediately prevents further damage to the roof. On the other hand, a delay could lead to high repair bills. Professionals can locate and repair all types of roof leaks in a matter of a few hours in most cases.

2. Failing Lead Flashings

Another important sign of an unhealthy roof is failing lead flashings. To be sure, lead flashings are commonly found in chimney stacks and parapet walls. If ignored, these flashings can cause damage to these areas.

Professionals can inspect and upgrade your home’s led flashings to prevent any damage, even if you cannot see the problem with the naked eye as of now. The upgradation or renewal of roof flashing also reduces the risks of water penetration of the roof and increases its life.

3. Slipped or Broken Tiles

Over time, the tiles on your roof may shift, break, or crack. This not only looks bad but can also let water seep into your roof. In the long run, it could be problematic for your home. It may lead to damage, mould on your walls and furniture and even problems with the structure of your house.

Keep an eye out for broken or missing roof tiles and cracked, curling, or completely missing tiles. If you notice any of these issues, it is essential to address them promptly to prevent further deterioration of your roof and, eventually, your home sweet home.

4. Failing cement work

Another major sign of an unhealthy roof is failing cement work, which clearly shows that you need immediate repair work. For the unversed, the root cause of failing cement work is water penetration. If the cement work continues to deteriorate, it could impact the chimney stacks the most, primarily due to the high exposure to the elements.

Professionals can work on failing cement work by repointing brickwork and repairing cracking or bulging rendering. These processes protect your property from water penetration and damage and increase the life of the roofs.

5. Sagging Roof Deck

A sagging roof deck is a serious red flag that your roof is in trouble. This can be caused by excessive moisture, the weight of accumulated snow, or deteriorating roofing materials. One way to identify this issue is by visually inspecting the exterior of your roof for any noticeable dips or sags. Additionally, if you observe interior signs such as cracked paint or unusual ceiling stains, it could be an indicator of a sagging roof.

A sagging roof not only compromises the aesthetics of your home but also poses a significant risk to its structural stability. If you notice any sagging, it is imperative to consult with a roofing professional to assess the extent of the damage and determine the best course of action.

6. Moss or Algae Growth

The presence of moss or algae on your roof can be indicative of underlying issues. While it may seem harmless, these organisms can trap moisture, leading to the premature deterioration of roofing materials.

Additionally, moss and algae growth can spoil the aesthetic appeal of your home. Regularly inspect your roof for any spots of greenery. Typically, moss appears as a green, fuzzy layer, while algae can present as dark streaks.

If you notice a notable change, consult with a professional to address the problem and prevent further damage.

7. Increased Energy Bills

An often-overlooked indicator of an unhealthy roof is a sudden spike in energy bills. A compromised roof can lead to poor insulation, allowing warm air to escape in the winter and cool air to seep out in the summer.

If you notice a significant increase in your energy costs, it may be a signal that your roof is not providing adequate protection. Addressing insulation issues and fixing any leaks can help improve your home’s energy efficiency and save you money overall.


In conclusion, neglecting the health of your roof can lead to costly repairs and greater structural damage. By being observant of the warning signs, you can take proactive steps to maintain your roof and avoid major problems further down the line.
