Before & After Gallery
Customer's Concern
The homeowner contacted Rebel Roofing ACT after noticing water stains on the ceiling near the chimney following periods of heavy rain. They were also concerned about cracked ridge pointing and several loose ridge tiles that had become more noticeable over time. A previous temporary repair around the chimney had started to fail, allowing water to penetrate the roof during wet weather. With Canberra’s colder months approaching, the homeowner wanted a permanent solution to prevent further leaks, protect the roof structure, and avoid more extensive repairs in the future.
Roof Inspection Findings
A detailed roof inspection was carried out before any repair work began to identify the source of the leak and assess the overall condition of the roof. The inspection confirmed several issues affecting both the chimney and the ridge line, all of which required attention to restore the roof’s weather resistance.
Failed Chimney Flashing
The existing chimney flashing had deteriorated over time, leaving visible gaps where the flashing met the brickwork and roof surface. These openings allowed rainwater to enter around the chimney during wet weather.
Water Penetration Around the Chimney
Signs of water ingress were found around the chimney area, confirming that the failed flashing was allowing moisture to reach the roof structure. Addressing the flashing was essential to stop further leaks and prevent damage to the underlying timber.
Cracked Roof Pointing
The flexible pointing along the ridge capping had cracked and separated in several sections due to years of exposure to Canberra’s changing temperatures. These cracks reduced the roof’s ability to resist water and wind.
Loose Ridge Capping
Several ridge tiles had become loose as the bedding mortar beneath them deteriorated. Although the tiles remained in place, movement was evident and rebedding was required to secure them correctly.
Deteriorated Bedding Mortar
The original bedding mortar had broken down in multiple areas, reducing its ability to support the ridge capping. Replacing the failed bedding provided a solid base before new pointing was applied.
Weather-Related Wear
General ageing from prolonged exposure to sun, heavy rain, frost, and strong winds had contributed to the deterioration of the flashing, bedding, and pointing. These are common issues found on older tiled roofs throughout Canberra.
Moss and Debris Build-up
Minor moss growth and accumulated debris were present around sections of the roof and ridge line. These areas were cleaned as part of the preparation process to ensure the new bedding and pointing bonded properly and the flashing could be installed correctly.
Roof Inspection Findings
Following the roof inspection, our team completed a series of repairs to restore the roof’s structural integrity and improve its resistance to Canberra’s weather conditions. The project included:
- Comprehensive roof inspection to identify the source of leaks and assess the overall roof condition.
- Safe removal of the failed chimney flashing surrounding the chimney.
- Installation of new weatherproof chimney flashing to create a durable, watertight seal.
- Removal of loose ridge tiles and deteriorated bedding mortar.
- Ridge tile rebedding using fresh bedding mortar to securely reset the ridge capping.
- Full roof repointing with a flexible, weather-resistant pointing compound to protect the ridge line from movement and moisture.
- Cleaning of the work area, including the removal of loose debris and old roofing materials.
- Final quality inspection to verify that the chimney flashing, rebedded ridge tiles, and repointed ridge line were completed to a high standard and that the roof was fully sealed and ready to withstand the elements.
Materials Used
Using quality roofing materials is essential for long-lasting repairs, particularly on tiled roofs exposed to Canberra’s changing weather conditions. For this project, we selected materials designed to provide a durable, weather-resistant finish and reliable performance over time.
Flexible Roof Pointing Compound
A premium flexible pointing compound was applied to all ridge tiles after rebedding. Unlike traditional mortar, it accommodates natural roof movement caused by temperature changes, helping reduce the risk of cracking and extending the life of the ridge line.
Bedding Mortar
Fresh bedding mortar was used to securely reset the loose ridge tiles. This created a stable foundation before the new pointing was applied, ensuring the ridge capping remained firmly in place.
Lead-Free Chimney Flashing
New lead-free chimney flashing was installed around the chimney to form a watertight barrier where the roof meets the brickwork. The flashing was shaped and fitted to direct rainwater away from vulnerable joints and prevent future leaks.
Roofing Sealant
A high-performance roofing sealant was applied where required to reinforce weatherproof joints and provide additional protection around flashing details and roof penetrations.
Roofing Screws and Fixings
Corrosion-resistant roofing screws and fixings were used where necessary to securely fasten roofing components and maintain the stability of the repaired sections.
Roof Surface Preparation
Before repairs began, the roof surfaces were thoroughly cleaned and prepared by removing loose mortar, debris, and contaminants. Proper preparation helped ensure strong adhesion of the bedding mortar, pointing compound, and flashing system, contributing to a durable, long-lasting repair.
Results
Following the completion of the repairs, the roof was fully restored and better equipped to withstand Canberra’s changing weather conditions. The combination of new chimney flashing, ridge tile rebedding, and flexible repointing addressed the existing defects while improving the roof’s long-term performance.
- New watertight chimney flashing installed, creating a secure seal around the chimney and eliminating the primary source of water ingress.
- Ridge tiles securely rebedded with fresh bedding mortar, restoring stability along the roof’s ridge line.
- Flexible roof pointing applied across the rebedded ridge capping to accommodate natural roof movement and reduce the likelihood of future cracking.
- Improved weather protection against heavy rain, strong winds, frost, and seasonal temperature changes common in Canberra.
- Reduced risk of future roof leaks by repairing vulnerable areas around the chimney and ridge capping before further deterioration could occur.
- Enhanced structural integrity by replacing deteriorated materials with durable, weather-resistant roofing products.
- Neat, professionally finished appearance, improving the overall presentation of the roof while maintaining its functionality.
- Roof prepared for long-term performance, giving the homeowner confidence that the repaired areas are protected and ready to handle Canberra’s changing climate.
Maintenance Tips After Chimney Flashing, Rebedding & Repointing
Regular roof maintenance helps extend the life of roofing repairs and allows potential issues to be identified before they develop into major problems. After completing chimney flashing installation, ridge rebedding, and repointing, homeowners can protect their roof by following these maintenance steps.
Inspect Chimney Flashing Annually
Check the area around the chimney at least once a year for signs of deterioration. Look for gaps, damaged seals, rust, movement, or water stains inside the home that may indicate flashing problems.
Check Ridge Tiles After Severe Weather
Strong winds, storms, and heavy rainfall can affect ridge capping over time. After major weather events, inspect the roof for loose ridge tiles, cracked pointing, or visible movement along the ridge line.
Keep Gutters and Roof Drainage Clear
Blocked gutters can cause water to overflow onto roof areas and increase moisture exposure around flashing, tiles, and roof joints. Regular gutter cleaning helps maintain proper water flow away from the roof.
Schedule Periodic Roof Inspections
Professional roof inspections help identify early signs of wear, including cracked pointing, deteriorated bedding mortar, damaged tiles, and failing flashing. Regular checks are especially important for older tiled roofs in Canberra.
Repair Minor Issues Before They Worsen
Small cracks, loose tiles, or minor gaps around flashing can allow water to enter and lead to more expensive repairs. Addressing these issues early helps protect the roof structure and prevent further deterioration.
Monitor the Roof After Heavy Rain
After significant rainfall, check for signs of leaks such as ceiling stains, damp areas, mould growth, or water marks near chimneys and roof penetrations. Early detection can prevent more extensive damage.
Why Canberra Roofs Often Need Chimney Flashing, Rebedding & Repointing Repairs
Canberra’s climate places constant pressure on residential roofing systems throughout the year. Homes with tiled roofs are exposed to hot summers, cold winters, heavy rainfall, strong winds, and regular temperature changes that can gradually weaken roofing components.
Heavy Rainfall
During periods of heavy rain, damaged chimney flashing and cracked roof pointing can allow water to enter vulnerable areas of the roof. Chimneys create natural junction points where water must be redirected away from the roof surface, making correctly installed and maintained flashing essential.
Frost and Cold Winter Conditions
Canberra experiences cold winter temperatures and regular frost, which can affect roofing materials over time. Moisture trapped in small cracks can expand during freezing conditions, causing pointing compounds and bedding mortar to deteriorate faster.
Strong Winds
High winds can place additional stress on ridge capping and chimney flashing. When bedding mortar weakens or ridge pointing cracks, ridge tiles can become loose and more vulnerable to movement during storms.
Summer Heat and Temperature Changes
Canberra summers bring high temperatures that cause roofing materials to expand, followed by contraction as temperatures drop. This repeated movement can contribute to cracking in older mortar-based pointing and deterioration around flashing joints.
Thermal Movement
Roof tiles, mortar, and metal flashing materials naturally expand and contract at different rates. Over many years, this movement can weaken seals, create gaps, and reduce the effectiveness of older roof repairs.
Ageing Tile Roofs
Many Canberra homes feature tiled roofing systems that have been exposed to decades of weather conditions. Over time, ridge bedding can break down, pointing can crack, and chimney flashing can deteriorate, increasing the risk of leaks and water damage.
Regular roof inspections and timely repairs help identify these issues before they develop into larger problems. For this Kambah roof project, replacing the failed chimney flashing, rebedding the ridge tiles, and applying new flexible pointing restored the roof’s protection against Canberra’s climate.
