Your roof is part of your home’s foundation. A well looked after roof not only protects your home from the elements but also the overall condition of your home, preventing structural damage, water damage and costly repairs. Many homeowners however overlook the importance of regular inspections and roof pressure cleaning. Ignoring the signs of roof damage can lead to long term consequences like mold growth, energy inefficiency and even roof collapse.
In this guide we will look at the common signs that mean it’s time to call in a professional for roof cleaning and repairs including clogged gutters, moss growth, roof leaks and water infiltration. By recognising these signs early you can take a proactive approach to roof care and extend the life of your roof and improve your home’s energy efficiency.
Excessive Moss, Algae or Lichen Growth
One of the first signs your roof needs a clean is the visible presence of moss growth, algae streaks or lichen. These organisms love damp environments and damage your roof’s surface by trapping moisture. This moisture can lead to mold growth and deterioration of your roofing materials whether they are asphalt shingles, metal roofs or roof tiles.
The longer moss or algae are left to grow, the harder they are to remove and the more damage they cause. They cause water leakage and can lead to structural issues over time. Moss growth weakens the roof’s ability to drain water, increasing the risk of water stains on both the exterior and interior of your home. If left untreated, this moisture can seep into the roof deck and cause water damage and costly repairs.
Discoloration and Dark Stains
Water stains, dark spots and streaks are not just cosmetic, they often mean water damage. When mold growth or algae starts to grow on your roof it can cause the shingles to deteriorate. This can also cause granule loss especially on asphalt shingle roofs where granules in the gutter become displaced.
As the granules wear off your roof becomes less resistant to harsh weather and UV rays and deterioration accelerates. Dark streaks or black streaks caused by algae can also decrease your home’s curb appeal and market value. If left untreated these stains can lead to long term damage and require not just a clean but a full roof restoration or even a new roof.
Gutters Clogged
One of the most obvious signs your roof needs professional help is gutters clogged. When debris, leaves and even asphalt shingle granules get in your gutters, water can’t drain off your roof. This causes water damage to your roof and your home’s foundation.
Clogged gutters can also cause roof leaks and water in your attic or ceiling. If you see your gutters filling up with too much granules, it’s a sign your shingles are wearing down and may need minor repairs or in severe cases, emergency roof repair.
Gutter cleaning is crucial to your roof’s functionality. A professional roofer can do a full roof inspection and find any drainage issues that can cause water leakage and structural damage.
Roof Leaks and Water Infiltration
If you have a leaky roof, you may be dealing with one of the most serious signs of roof damage. Roof leaks are caused by damaged shingles, cracked roof tiles or improper installation of flashing around chimneys and vents. If left unchecked, even small leaks can cause extensive damage to the roof structure and inside.
Water stains on your ceiling or walls are a clear sign of water infiltration. Beyond the obvious water stains, you may also notice a musty smell or mould growth in your attic, both of which are signs the leak has been present for some time.
Regular roof inspections can catch leaks early and minor repairs before it becomes a bigger problem like a full roof replacement. Professional roof cleaning services also play a big role in preventing leaks by removing debris and organisms that cause moisture buildup.
Higher Energy Bills
If you notice a sudden increase in your energy bill, your roof might be the culprit. A dirty or deteriorating roof can’t insulate your home properly and makes it harder to maintain indoor temperature. As a result, you consume more energy and pay higher energy costs.
For example, moss and algae growth can block sunlight and make the roof retain moisture and reduce its reflectivity. This affects the roof’s overall energy efficiency especially during summer months when your roof should be reflecting heat away from your home.
Regular roof maintenance and cleaning can improve your roof’s energy efficiency by removing debris and making sure your roofing materials (metal roof, asphalt shingles, thatch roof) are working at its best.
Missing or Broken Roof Tiles
Missing or broken roof tiles are a sign your roof is open to further damage. This is most common after severe weather like storms or high winds. When tiles break or go missing it leaves your roof open to water intrusion and structural issues.
Missing tiles can also cause granule loss and weaken the overall structure of the roof, leading to water leakage and water damage. If left unchecked, this can affect the roof deck and even the roof structure itself.
For metal roofs rust and corrosion is a common problem when the coating wears off. Corrosion on metal roofs can cause water intrusion especially around the fasteners or seams. Regular roof inspections can help identify where tiles are damaged or missing and prevent further damage.
Sagging Roof or Deformed Roof Structure
A sagging roof or any dip in your roofline is a big red flag. It’s a sign of major structural damage that needs to be addressed now. This could be from water intrusion, which weakens the roof deck and causes the structure to sag over time.
Other factors like mold growth, moisture retention or a broken roof tile can also cause a deformed roof. If left unchecked this can lead to a complete roof collapse which is dangerous and costly.
If you see any signs of sagging, contact a professional roofing company now. Repointing and restoration may be required to fix the underlying issue and strengthen the roof structure before it gets worse.
Signs of Deterioration on Roof Valleys
The roof valleys where two slopes meet are critical for directing water off your roof. If these areas are showing signs of deterioration such as cracked or missing shingles this can lead to water damage quickly. Roof valleys are prone to water leakage because they handle a lot of water runoff during rainstorms.
When roof valleys are compromised they can allow water to seep into the roof decking and cause damage over time. Make sure your roof valleys are in good condition to prevent leaks and costly repairs down the line. Regular roof inspections can help you stay ahead of potential issues in these high risk areas.
Debris and Granules
If you’re finding asphalt shingle granules in your gutters or on the ground around your house it’s a sign your roof’s surface is deteriorating. Those granules help your roof withstand the elements, including severe weather like hail and high winds.
When granules start to wear off, your roof becomes more prone to water intrusion, water spots and roof deterioration. This can eventually lead to structural damage and roof replacement.
Also, debris like leaves and branches can trap moisture against your roof and cause moss growth and other biological growth. Keeping your roof clean of debris with regular cleaning can prevent these problems and extend the life of your roof.
Age of the Roof
The age of your roof is a big factor in its overall health and energy efficiency. Most roofs are designed to last between 20-30 years depending on the type of roofing material. As your roof gets older it becomes more prone to structural damage, mold growth and water intrusion.
An older roof is also more likely to have minor repairs that can turn into bigger problems if not addressed right away. Regular professional roofing inspections are key to identifying roof damage related to age so you can take preventative measures before a full roof replacement is needed.

How often should a professional roofing contractor inspect my roof?
Once a year, especially after severe weather. Regular inspections prevent water damage and structural issues.
Can roof cleaning really improve my home’s energy efficiency?
Yes! Removing debris, algae and moss from your roof restores its reflective properties and will improve energy efficiency and lower energy bills.
Do I need to clean my gutters regularly to maintain roof health?
Yes, clogged gutters can cause water intrusion and roof leaks and extensive damage. Regular gutter cleaning is key to preventing these issues.
How do I know if I need a full roof replacement vs. just repairs?
