Waterproofing Roof  Deck and Parapets"Waterproofing

Waterproofing a roof deck and parapets is crucial to protect the structure from water damage and ensure its longevity.

Using waterproofing products like Drizoro can be an effective solution. It’s crucial to address roof leaks promptly to prevent further damage to external and internal aspects of the building.

Steps to take to prevent water entry.

  1. Identify the Source of the Leak:
    • Determine the exact location of the roof leak. Check the interior of the building for water stains, dampness, or visible dripping. The point where water enters the interior may not necessarily be directly below the source on the roof, as water can travel along beams or other structures.
  2. Safety First:
    • Ensure safety for yourself and others in the building. Be cautious when inspecting the roof or performing repairs, especially if the roof is steep or damaged. Use appropriate safety equipment, including harnesses and fall protection gear.
  3. Contain the Damage:
    • Place containers or buckets under the leak to catch dripping water and minimize damage to the interior. Often creating a leak point so the water leaks from fewer points and gets out the ceiling where it may cause the plaster lining to collapse.
  4. Temporary Patch:
    • If the source of the leak is readily apparent and can be safely accessed. Apply a temporary patch. This can be done using Drizoro Maxplug, roofing tape, or a tarp. Simply directing the water away from the crack may be sufficient.
      Securely applied patches must withstand weather conditions until a permanent repair can be made.
  5. Call a Professional Waterproofer:
    • Roof repairs are best left to professionals. Contact licensed and experienced waterproofing contractors to properly assess the extent of the damage and provide a permanent solution.
  6. Inspect the Roof:
    • The roofing contractor will conduct a thorough inspection of the roof to identify the cause of the leak. Common issues include damaged or cracked flashings, clogged concrete box gutters, or deteriorated waterproofing membranes.
  7. Repair or Replace:
    • Based on the assessment, the roofing contractor will recommend either repairing the damaged area or replacing it. The choice will depend on the age and overall condition of the roof ie. worn away delamination, or UV damage to the membrane.
  8. Preventative Maintenance:
    • After repairing the roof, consider implementing a regular maintenance schedule to prevent future leaks. This may include gutter cleaning, checking for loose or damaged shingles, and addressing any issues promptly.
  9. Interior Repairs:
    • Once the roof is deck repaired, other contractors may be required to assess and repair any interior damage caused by the leak. This may involve replacing damaged drywall, insulation, or other materials. Ensure that the affected area is completely dry to prevent mould growth.
      If the roof is unable to be repaired economically from the top side, then the cost of removal of tiles, and the presence of other structures or protrusions may make it cost prohibitive.
  10. Insurance Claims (if applicable):
    • If the damage is extensive or if you have insurance coverage, contact your insurance company to initiate a claim. Document the damage with photographs and keep records of all expenses related to repairs.

A maintenance program to address roof leaks promptly is essential to prevent further structural damage and mould growth. Regular roof inspections and maintenance can also help identify potential issues before they become major problems. Roofing professionals have the expertise and equipment to properly diagnose and repair roof leaks, ensuring the long-term integrity of your building.
