Repairing a badly leaking concrete roof with a big crack requires proper attention to prevent further damage. While major repairs may require professional assistance, here are some steps you can take to address the issue without spending a lot of money:
Safety first: Ensure your safety and that of others by taking necessary precautions. If the leak is severe or if you are unsure about handling the repair yourself, it's best to consult a professional roofer or contractor.
Temporary fix: To minimize water damage in the short term, you can use a waterproof sealant or roofing cement to temporarily patch the crack. Clean the area around the crack, apply the sealant generously, and smooth it out with a putty knife or trowel. This temporary fix will buy you some time while you arrange for a permanent solution.
Locate the source: Assess the roof carefully to identify the main source of the leak. It may not necessarily be limited to the visible crack. Look for other potential areas where water may be entering, such as damaged flashing, loose or missing shingles, or deteriorated caulking around vents and chimneys.
Repair flashing and seal gaps: Check the flashing around any roof penetrations (such as vents, chimneys, and skylights) for signs of damage or deterioration. Replace or repair damaged flashing and use roofing sealant to seal any gaps or openings.
Address drainage issues: Ensure that the roof has proper drainage to prevent water from pooling. Clear any debris from gutters and downspouts and ensure they are functioning properly. Consider installing gutter guards to prevent future clogging.
Monitor and document: Keep an eye on the repaired area and monitor for any further leaks. Document the issues and take photographs to provide accurate information to professionals if needed.
Professional assessment: While the temporary fix may hold for some time, it's important to consult a professional roofer or contractor to assess the extent of the damage and provide a long-term solution. They can provide expert advice and guidance on the most cost-effective and durable repair options.
Remember, addressing a badly leaking concrete roof with a major crack requires proper expertise and may require significant repairs. Investing in professional assistance can help prevent further damage and potentially save you money in the long run.
