How do I Fix Mold Damage Due to Leaky Roofs

During the winter months we see a large amount of calls come into our office for roof tarping, floodingceiling dryout from roof leak, wet drywall, wet carpet, wet kitchens, wet flooring, wet cabinets, etc.  Typically this happens during the months of October, November, December, January, and February.  We usually see a couple to a dozen heavy rains that cause these types of damages. Call us today! 619.597.2003 for an assessment.

If damage due to rains is not taken care of correctly, mold damage can occur.  It can happen very quickly.  Typically within a few hours to a couple days mold will grow in an amount where it is visible and detrimental to the inhabitants of the property.  It will remain in that condition indefinitely and will get worse until it is professionally cleaned.  Mold will grow within a property when the following conditions are true: moisture is present, air-flow is low, and the mold has a substrate to grow on.

The perfect condition for this is behind drywall, in ceiling cavities, on stud walls or joist ceilings, under floor coverings, within cabinets, and in cabinets.  Basically, homes are the perfect breeding ground for mold.

When an area due to a leaky roof has a mold issue due to not being dried out correctly, at all, or unseen, the process to have it remediated is as follows:

1. Our trained, licensed technicians will setup containment around the affected area.  If this area is, for example, affecting 4′ x 4′ of ceiling in a living room, we would place 4 – 6 mil plastic around the affected area, containing the air in the “affected” bubble from the rest of the “unaffected” area.

2. Our technicians would be wearing personal protective equipment such as tyvek suits, HEPA masks and faceguards when they cut out any non-structural, porous components, back, wrap, and dispose of correctly from the jobsite.

3. We would HEPA vacuum the affected area.

4. Wipe down of affected areas with a surfactant to remove large areas of mold.

5. We would correctly dry the remaining structural components using properly sized dehumidifiers and air scrubbers.

6. We would apply an antimicrobial to the affected areas.

7. We would cleans the air using HEPA airscrubbers that pass “affected” air across a two-filter HEPA system and exhausts “unaffected” air to a duct directed outside of the property.  We would scrub the air for a minimum of 48 hours.

8. We would have the cleaning, drying, and mold extraction verified with a clearance test that would be a comparative analysis showing lower levels in the containment as compared to the control sample (usually outside the front door).  The testing would be provided by a 3rd party tester, not our office, leaving the results 3rd party (i.e. not testing our own work).


How long does the mold remediation process start?  For the example above it would be as follows:

1. Containment setup, 4’x4′ of affected area removed, wipe down with a  surfactant = 1 – 2 days.

2. HEPA vacuuming and final wipe down of “affected” areas within the containment = 1 – 2 days.

3. HEPA airscrubbing in preparation for air clearance testing = 2 – 3 days.

4. Time to wait for test results from lab = 1 – 4 days (labs are typically closed on Saturday and Sunday and depending on the cost of the test can take 1 to 2 days for results).
