TILE ROOF MAINTENANCE & REPAIRS

SealPro Coatings approved applicators employs a meticulous, step-by-step process to ensure your tiled roof remains leak-free and resilient, addressing all potential failure points with precision and care:

1. Detailed Roof Inspection: Our team conducts a thorough assessment of your tiled roof, identifying vulnerabilities such as cracked or deteriorated ridge mortar, broken tiles from movement or storm damage, issues around solar brackets or roof penetrations, blocked or misaligned valleys, poorly installed flashings, and chimney joints prone to leaks. This ensures we address all potential problem areas before they escalate.
2. Tile Replacement: Badly broken tiles, often caused by foot traffic during maintenance or storm damage, are replaced with new tiles to restore the roof’s structural integrity. If the tiles can’t be replaced it will be fixed using the StretchSeal Flex waterproofing system.
3. Roof Surface Preparation: Loose or deteriorated cement in ridges, flashings, or chimneys is carefully raked out, and cracks are opened to prepare a clean surface for repairs. This step is critical to ensure that subsequent fillings and waterproofing adhere properly and provide lasting protection.
4. Filling Cracks and Gaps: We apply Posi Skim Filler to fill cracks and gaps in ridges, flashings, and chimney joints. For flashings and chimneys, the filler is applied at a 45-degree angle between the roof tiles and parapet walls, creating a strong, angled seal that directs water away from vulnerable areas.
5. Valley Maintenance and Repair: Blocked valleys, often caused by debris like leaves or dirt, are opened and cleaned to restore proper water flow. In cases where valleys are misaligned or damaged, we fill gaps with Posi Skim Filler and strengthen them with the StretchSeal Flex waterproofing system, ensuring a watertight seal that withstands heavy rainfall.
6. Waterproofing with StretchSeal Flex: We apply StretchSeal Flex to ridges, flashings, solar brackets, and chimneys, embedding it with Flex to create a flexible, durable membrane that prevents leaks and accommodates thermal expansion and contraction. This system is particularly effective for sealing complex areas like solar bracket penetrations and open tiles left exposed after roof work or storm damage.
7. Protective Topcoat with PlasRoof Roof Paint: Repaired sections are overcoated with PlasRoof Roof Paint, a UV-stable coating that protects the waterproofing system from South Africa’s intense sunlight and enhances the roof’s aesthetic appeal. For roofs without this topcoat, we recommend reapplying a UV-protective coating every 3 years to maintain durability and prevent degradation.
