Roof leaked on to insulation and plasterboard waiting to be plastered

Best solution would be remove the damaged plasterboard and Insulation, Once plasterboard gets wet it never really recovers

Hi There, Hard to give a definitive answer without actually seeing the level of water damage, but to give you an idea. If its solid, rigid insulation such as Celotex you should be fine as water will not penetrate the board. The plasterboard is a different thing if it is excessively wet I would recommend changing but slight water ingress should be fine and will dry out. People have leaks in homes all the time and you dont rip out the wetted boards, you just let it dry out. I would try and get the water entrance point addressed immediately then give the damaged boards time to dry out. Any decent plasterer when they turn up will let you know if they are happy to skim onto the boards or advise they should be changed. Hope this helps, goood luck with the rest of youe renovation

If the insulation and plasterboard have become wet due to a leak in the new roof, it's important to address the issue promptly to prevent further damage and potential health hazards like mold growth. Here are a few steps you can take: 1. **Assess the Damage**: Determine the extent of the damage caused by the leak. If only a small area has been affected and the materials are not extensively soaked, they may dry out without needing replacement. However, if a large portion is wet or if the materials have been soaked through, replacement might be necessary. 2. **Allow Drying Time**: If the affected area is relatively small and the materials are not saturated, you can allow them to dry out thoroughly before proceeding with any repairs or plastering. Ensure proper ventilation in the area to aid the drying process. You may use fans or dehumidifiers to expedite drying if necessary. 3. **Monitor for Mold**: Keep a close eye on the affected area for any signs of mold growth during the drying process. If you notice any mold developing, it's crucial to address it promptly to prevent further spread. Mold can pose health risks and may require professional remediation. 4. **Consult with Professionals**: Consider consulting with a professional contractor or a building inspector to assess the damage and determine the best course of action. They can provide expert advice tailored to your specific situation and recommend whether replacement or drying out the materials is the appropriate solution. 5. **Ensure Proper Repairs**: Once the affected materials have dried out completely, ensure that any necessary repairs to the roof are completed to prevent future leaks. It's essential to address the root cause of the issue to prevent recurring problems. In summary, whether the insulation and plasterboard need to be replaced or can be dried out depends on the extent of the damage and the saturation level of the materials. It's essential to assess the situation carefully and take appropriate action to ensure the safety and integrity of your home. If in doubt, consulting with professionals is always a wise decision.

If its only a little bit then will be fine to let it dry out.
