You can see those ugly black streaks on roofs almost everywhere. Algae is a problem in most of the country, especially in hot, humid climates, and once it takes hold, it’s hard to get rid of, so prevention is the goal.
You
often hear the term “green building” as consumers seek to purchase homes that
are often built using recycled materials or are low in energy usage. Both are
important goals, but they must be pursued in a way that preserves a home’s
ability to manage and repel moisture.
Residential re-roofing contractors are by
definition working on a building that could have underlying problems, including
improper ventilation, undiagnosed roof leaks and mold.
The best way to keep mold at bay is to control moisture. But even the most diligent homeowner or facility manager can’t plan for every situation. If a moisture issue does lead to mold growth and the need for remediation, testing can help ensure that the affected areas have been properly remediated.
Quick! Look up at your roof! Is it dirty,
streaky, stained, and downright ugly? If you answered yes to any of the above,
then chances are your home is being attacked by algae - a living organism
growing on what was once likely a beautiful roof.
Ventilating today's cathedral ceilings is more of a challenge than ventilating regular roofs. Because of the isolated air spaces in rafter cavities, cathedral ceilings are especially prone to moisture damage - posing unique ventilation problems.
