How to Repair a Flat Roof Leak

Find The Leak: Pinpointing the Source

The first step in addressing a flat roof leak is identifying its source. Follow these steps to effectively locate and understand the origin of the leak:

  1. Water Stains on the Ceiling: Measure the distance from water stains to the two nearest walls.
  2. Exterior Assessment: Climb onto the roof and apply interior measurements to the exterior.
  3. Area Examination: Examine the approximate area where the stain appears underneath.
  4. Slope Search: If no damage is visible above the stain, search up the slope from the stain.
  5. Obvious Holes or Cracks: Identify any obvious holes or cracks in the roof membrane as potential sources.
  6. Worn-Out Areas: Plan to patch any worn-out areas, as they may lead to leaks in the future.
  7. Edge Inspection: Check the edges of the roof for places where the membrane may be peeling back.

How To Fix Small Cracks and Holes: DIY Solutions

For minor cracks and holes, a DIY approach can effectively address the issue. Follow these detailed steps for a successful repair:

  1. Dry the Work Area: Thoroughly dry the work area with old cotton towels if it’s wet.
  2. Roof Cleaning: Sweep the roof clean to ensure a debris-free work surface.
  3. Blister and Bubble Management: Cut open blisters and bubbles on the membrane, trimming close to the membrane.
  4. Damaged Material Removal: Scrape off any other damaged roof material without cutting into sound roofing.
  5. Roofing Cement Application: Spread 1/8 inch of roofing cement over the repair area with a trowel.
  6. Fiberglass Mesh Inclusion: Cut a piece of fiberglass mesh to fit the repair area, lay it into the roofing cement, and spread more roofing cement over it.
  7. Gravel Protection: Sprinkle gravel into the fresh cement to protect the patch from sun damage.
  8. Edge Crack Filling: Fill any cracks along the edges of the roof with caulk for a comprehensive repair.

How To Patch a Membrane: Tackling Larger Leaks

For more significant leaks, patching the membrane is necessary. Follow these detailed steps for effective resolution:

  1. Membrane Material Selection:
    a) Choose a roofing membrane or a roof repair kit based on your specific needs.
  2. Membrane Patching Process:
    a) Cut and trim away damaged membranes.
    b) Spread 1/8 inch of roofing cement into the exposed repair area.
  3. Cement Squishing:
    a) Squish cement under the edges of undamaged roofing material.
  4. Patch Attachment:
    a) Cut a membrane patch to fit the repair area, attach it, and spread more roofing cement over the patch.
  5. Double Patching Technique:
    a) Cut another patch larger than the first by 6 inches in all directions.
    b) Attach this patch over the first patch, spread more cement, and press fresh gravel into the wet cement.

How To Reseal the Roof: Maintaining Roof Longevity

An aging flat roof may require a fresh layer of sealant to maintain its integrity. Follow these comprehensive steps for effective resealing:

  1. Preparation Phase:
    a) Sweep the roof clean and ensure the surface is dry for optimal adhesion.
  2. Bitumen Primer Application:
    a) Use a paint roller to apply 1/2 inch of bitumen primer over the roof. Follow the manufacturer’s directions for drying time.
  3. Mesh Unrolling Process:
    a) Unroll a strip of fiberglass mesh across the roof width in sections.
    b) Cut the mesh as necessary to fit and fold back the ends, weighting them down with boards or buckets.
  4. Sealant Stirring and Application:
    a) Stir bitumen roof sealant until smooth.
    b) Dip a paint broom into the sealant, working in one direction to spread it evenly.                                                   c) Ensure a sealant layer thickness of about 1/2 inch.
  5. Mesh Embedding:
    a) Unfold the mesh and cover it with more sealant.
    b) Press the mesh into the sealant, spreading additional sealant over it.
  6. Second Coat Application:
    a) About 12 hours later, apply a second layer of sealant.
  7. Inspection and Final Touch:
    a) Inspect the dried coat for dips, gaps, or imperfections.
    b) Fill any identified imperfections with more sealant.
  8. Reflective Coating for Added Protection:
    a) For a final layer of protection, apply a reflective coating to delay sun damage.
