Torch Felt Flatroof
Certainly! Felt roofs are commonly used for flat roof extensions and outdoor buildings due to their simplicity in application, affordability, and ease of maintenance. However, these roofs can encounter issues over time, including splitting, lifting, and leaking. Here’s an overview of the process for a temporary repair using a paint-on water-based sealant to address these problems:
Common Felt Roof Repair Issues:
- Splitting: Occurs when the felt material develops cracks or splits due to wear and tear, weather conditions, or age.
- Lifting: Refers to areas where the felt has detached or lifted from its original position, potentially causing gaps or entry points for water.
- Leaking: Water ingress through the roof due to damages like splits or lifting, leading to dampness or water stains inside the building.
Temporary Repair Process Using Paint-On Water-Based Sealant:
- Identifying Issues: Look for signs of damage inside the building, such as watermarks or damp patches. Measure the distance from the affected area to the nearest wall to locate the problem area.
- Roof Inspection: Ascend to the roof and inspect the identified area. Check for splits, lifting sections, or any signs of damage. Pay attention to any irregularities, ridges, or pooling of water that might indicate weakened areas.
- Preparation: Remove accumulated water using towels and clean the affected area by sweeping away dirt, debris, or moss.
- Applying Waterproof Sealant: Use a paint-on water-based sealant to cover the damaged or problematic area of the felt roof. Ensure the application is around 2mm thick, focusing on joints, splits, or lifted sections for complete coverage.
- Reinforcement (if necessary): If there are splits or areas that seem vulnerable, consider reinforcing them with additional sealant or using a plasterer's scrim to add an extra layer of protection.
- Completion: Once the sealant has been applied and dried, it forms a protective layer over the damaged area, temporarily preventing further leaks or issues. This temporary fix allows time to plan for a more permanent repair or replacement if needed.
This temporary repair method using a paint-on water-based sealant can provide immediate relief by addressing splitting, lifting, and leaking issues in felt flat roofs. However, for a long-term solution and to ensure the integrity of the roof, it’s advisable to consult professional roofing specialists who can assess the damage and recommend appropriate repairs or replacements.
