Complex Roof Repair Project in Summer Hill: A Detailed Case Study
Project Overview
At Skydog Roofing, we recently completed a challenging roof repair project at Summer Hill that showcased our expertise in handling multiple roofing issues simultaneously. This case study details our approach to addressing water leaks in both metal and tile roof sections, demonstrating our commitment to providing comprehensive roofing solutions for Sydney homeowners.
Initial Assessment
Our team conducted a thorough inspection of the property, identifying two critical areas requiring immediate attention:
- A lower metal roof section with significant water pooling issues around a skylight
- A damaged tile roof section above the front bay windows showing signs of structural compromise
These issues required different approaches and expertise, making this project particularly interesting from a technical perspective.
Detailed Inspection Findings
Lower Metal Roof Section Analysis
Upon closer inspection of the metal roof section, we discovered several concerning issues:
- Heavy accumulation of organic debris (leaves, soil) and construction materials (pavers, timber posts)
- Significant water pooling due to inadequate drainage
- Compromised skylight flashings positioned too low relative to water levels
- Borderline pitch angle for the existing corrugated profile
- Direct exposure to overhanging trees, contributing to ongoing debris accumulation
The combination of these factors created perfect conditions for water ingress, particularly during heavy rainfall events. The low pitch of the roof, combined with debris buildup, was causing water to back up and overflow the existing flashings.
Top Tile Roof Evaluation
The tile roof section over the bay windows presented its own set of challenges:
- Visible impact damage to multiple tiles
- A completely dislodged ridge cap
- Sequential displacement of adjacent ridge caps
- Compromised wall flashing integrity
- Multiple entry points for water infiltration
The damage pattern suggested a significant impact event, possibly from fallen branches or storm debris, which had created a cascade effect of structural compromises.
Project Challenges
This project presented several unique challenges that required careful consideration:
- Working with multiple roofing materials and systems simultaneously
- Addressing immediate leak issues while implementing long-term preventive measures
- Maintaining structural integrity during the repair process
- Ensuring proper integration between different roofing sections
- Managing safe access to all work areas, particularly around the bay windows







Implementation of Solutions
Metal Roof Section Renovation
Our comprehensive solution for the metal roof section included:
- Complete removal of all debris and existing roofing materials
- Installation of new structural supports:
- H2 Treated Pine Timber Battens for enhanced durability
- 60mm Anti-condensation Insulation blanket across the entire affected area
- Installation of premium roofing materials:
- 0.48 BMT Colorbond Klip Lok Roof sheeting, specifically chosen for low-pitch applications
- 0.55BMT Custom Folded Apron Flashings
- Enhanced Skylight Flashings with 100mm minimum height
- Diverter V Flashings for improved water management
- Integration of a new drainage system:
- 0.55BMT Custom folded Colorbond Box Gutter
- New nozzle connection to existing downpipe system
Tile Roof Restoration Process
The tile roof section required a methodical approach:
- Professional scaffold installation for safe access
- Careful selection and installation of matching second-hand ridge caps
- Implementation of a multi-layer waterproofing system:
- Premium Wakaflex flashing for roof-to-wall transitions
- Custom folded Colorbond over-flashing with 20mm wall chase
- Color-matched materials for aesthetic integration
- Complete ridge capping restoration using dark red flexible pointing
Project Outcomes
The completed project achieved several key objectives:
- Complete resolution of water infiltration issues
- Enhanced structural integrity of both roof sections
- Improved water management and drainage
- Extended roof system longevity
- Aesthetic improvement while maintaining architectural integrity
Ongoing Maintenance Recommendations
To ensure the longevity of the repairs, we recommend:
- Regular Inspections:
- Quarterly visual inspections of all repaired areas
- Annual professional assessment of structural integrity
- Post-storm checks for any damage or debris accumulation
- Preventive Maintenance:
- Regular cleaning of gutters and drainage systems
- Removal of accumulated debris from roof surfaces
- Inspection of seals and flashings for early signs of wear
