8 Common Problems With Tiled Roofs

As your home deteriorates and ages over time, there are 8 common problems we find with tiled roofs;


  • Broken roof tiles  – From weathering, ground movement or even walking on the roof. Broken tiles are common and can lead to water leaks during rainfall.
  • Broken ridgecapping  – A combination of age, ground movement and poor pointing materials used in the initial construction of your roof generally leave ridgecaps open to potential leak issues.
  • Bedding and pointing  – Cement pointing is a combination of sand and cement that was once a common bonding agent used in roofing ages. Over time it breaks down with ground movement and weathering. Flexible pointing is now available as a replacement.
  • Broken tile clips  – Tile clips are known to commonly break and as they do, become clogged causing blockages and a free flow of water.
  • Valley clips  – These are known to break, causing tiles in the valleys to slip and as a result can lead to water leaks.
  • Sarking  – The foil designed to reduce the transmission of moisture which acts as a home’s second skin to protect from weather. As this ages it can tear or be damaged from other trades working in or on your roof.
  • Valley irons  – A gutter system installed during construction of a home where 2 roofs meet. These can be found to be installed not wide enough and during heavy rainfall, cannot cope with the volume of water.
  • Valley seal  – A foam product designed to prevent water entering the roof cavity during heavy rainfall can deteriorate over a long period and needs to be replaced.



How to Maintain Your Tiled Roof

Keeping your roof in its best condition is simple. Make sure you inspect the roof regularly to check for any of the problems listed above. Also keep an eye out for any debris, especially after a storm and clear away any leaves or branches.


If you notice any problems with your roof or it needs maintaining, contact the team at JMZ Roof Restorations.We specialise in Tiled Roof Repairs and Tiled Roof Restorations.

Your roof silently protects your home from Brisbane's intense sun, sudden storms, and everything in between. But like any hardworking defender, it can show signs of wear that demand immediate attention. Ignoring these warning signals can lead to costly repairs, structural damage, and decreased property value. At JMZ Roof Restorations, we've been helping Brisbane homeowners since 1992, restoring over 35,000 roofs and building a reputation for quality and reliability. Through decades of experience, we've learned to spot the telltale signs that indicate when a roof needs immediate professional attention. This guide will walk you through five critical warning signs that your roof requires immediate restoration, helping you protect your investment and maintain your home's value. Sign 1: Visible Cracks or Breakage Cracks and breakage are among the most obvious signs that your roof needs immediate attention. These issues can appear in various forms depending on your roof type. Identifying Cracks and Breakage For tiled roofs, look for cracked, chipped, or completely broken tiles. These often occur after storms, from falling branches, or simply due to the natural aging process and weathering. Metal roofs may develop stress cracks, particularly around fasteners or where panels meet. Even small hairline cracks can quickly expand during Brisbane's temperature fluctuations. Walk around your property and inspect your roof from ground level. Use binoculars to get a closer look at suspicious areas. Pay special attention to areas where different roof sections meet, around chimneys, and near gutters. The Consequences of Ignoring Damage Cracked or broken roofing materials create immediate entry points for water. What starts as a small crack can become a major leak during the next heavy rainfall. Water infiltration can damage your home's structure, insulation, and interior finishes. The longer you wait, the more expensive the repairs become. A single broken tile might cost a few dollars to replace, but the water damage it allows can result in thousands of dollars in repairs to ceilings, walls, and flooring. Sign 2: Accumulation of Moss or Algae Brisbane's humid climate creates perfect conditions for moss and algae growth on roofs. While these organisms might seem harmless, they can cause significant damage over time. Why Moss and Algae Are Problematic Moss retains moisture against your roof surface, creating an environment that accelerates deterioration. The roots of moss can work their way into small cracks and crevices, gradually expanding them. This process is particularly damaging to tiled roofs, where moss can lift tiles and compromise the roof's water-shedding ability. Algae, while less structurally damaging than moss, create unsightly black or green streaks that significantly impact your home's curb appeal. These stains can permanently discolor roofing materials if left untreated. The Solution: Professional Cleaning and Restoration Attempting to remove moss and algae yourself can be dangerous and potentially damaging to your roof. Pressure washing, for example, can force water under tiles or damage protective coatings on metal roofs. Professional roof restoration includes thorough cleaning using appropriate techniques and products. At JMZ, we use specialised cleaning solutions that eliminate moss and algae without damaging your roof materials. Following cleaning, we apply protective coatings that help prevent future growth. Sign 3: Leaks and Water Damage Roof leaks represent one of the most serious problems requiring immediate attention. Even small leaks can quickly escalate into major structural issues. I dentifying Leaks and Water Damage Interior signs of roof leaks include water stains on ceilings or walls, peeling paint, and damp spots that appear after rainfall. You might notice a musty smell in certain rooms, which often indicates hidden water damage. Don't assume that water stains directly below indicate the leak's location. Water can travel along roof timbers and appear in unexpected places. Professional inspection is essential to locate the actual source of infiltration. The Serious Consequences of Roof Leaks Water damage extends far beyond cosmetic issues. Persistent leaks can rot wooden roof structures, damage insulation, and create conditions for mold growth. In severe cases, structural integrity can be compromised, leading to sagging or even collapse. Electrical systems can also be affected, creating safety hazards. Water and electricity don't mix, and roof leaks can damage wiring, outlets, and fixtures. Sign 4: Age of the Roof The age of your roof is a critical factor in determining when restoration becomes necessary. Different roofing materials have varying lifespans, and Brisbane's harsh climate can accelerate aging. Understanding Roof Lifespan Tiled roofs typically last 20-30 years with proper maintenance, while metal roofs can last 25-40 years. However, Brisbane's intense UV radiation, severe storms, and humidity can reduce these lifespans significantly. Factors that affect roof aging include the quality of original installation, maintenance history, and exposure to extreme weather. Roofs facing north or west often age faster due to increased sun exposure. The Benefits of Proactive Restoration Rather than waiting for complete roof failure, proactive restoration can significantly extend your roof's lifespan. This approach is often more cost-effective than complete roof replacement and can add substantial value to your property. JMZ's restoration process includes comprehensive inspection, cleaning, repairs, and protective coating application. Our 10-year warranty provides peace of mind, knowing that your investment is protected. Protecting Your Investment: Why Professional Restoration Matters Your roof is one of your home's most important components, and its condition directly impacts your property's value and your family's safety. The five signs discussed in this guide – visible damage, moss and algae growth, leaks, sagging, and age – all indicate that professional restoration is needed. At JMZ Roof Restorations, we've built our reputation on quality workmanship and customer satisfaction. Since 1992, we've helped thousands of Brisbane homeowners protect their properties with professional roof restoration services. Our fully licensed and insured team uses the best products available, backed by our unique 10-year warranty. Don't wait until minor issues become major problems.
