The Roof Mold Connection
You think a leaky roof is a problem? Wait until you read what can happen when that moisture leads to mold. Many building owners are starting to understand how mold can degrade indoor air quality, which can result in “sick building” symptoms and potential lawsuits.
“It appears moisture may be the single most probable catalyst to affect mold growth,” notes Curtis Liscum of Benchmark, a leading roofing consulting firm that partners with EMC on roof inspections. “Our experience has proven that leaks in a building can contribute to mold growth within as little as 24 to 48 hours.”
Benchmark roof inspectors have observed mold in ceiling tiles at areas of repeated roof leaks or areas where a lack of insulation creates condensation drips. They also note that mold can spread in gypsum board behind vinyl wallpaper where roof/window/wall leaks or condensation create a moist environment and the vinyl wallpaper prevents the moisture from drying out into the interior of a room.
In Case of Mold
Benchmark and EMC loss control experts stress that extreme care and diligence should
be exercised to ensure that hidden and hard-to-see surfaces are thoroughly investigated
for mold. Moisture meters should be utilized to determine excessive moisture content that
would promote fungal growth. When investigating for mold, it is important to follow these safety tips:
- Do not touch mold or moldy items with your bare hands
- Do not get mold or mold spores in your eyes
- Do not breathe in mold or mold spores
- Use Personal Protective Equipment (PPE) such as a respirator, gloves and eye protection
Once the extent of mold is determined by visual assessment, remediation is next. Nonporous and semiporous materials that are structurally sound can usually be cleaned. Porous materials generally require removal and disposal.
Be Aggressive About Roof Maintenance
It appears that mold growth and roof leaks are directly related. That being the case, annual
roof maintenance may be the first line of defense against mold development. If leaks do exist,
they must be investigated and repaired immediately. An aggressive maintenance program should
not only provide tangible results in mold prevention, but should go a long way in improving
the health and welfare of employees, staff and visitors to your building.
