Can A Leaking Roof Really Cause Mold In My Home?

Allstate Exteriors • March 7, 2022

Mold spores are in every cubic foot of air, including the ones we are breathing. No worries — most mold is harmless. Yet inside a home, a leaking roof can cause harmful mold to spread rapidly throughout your attic and down into your living space. To stop unhealthy mold, you need to have a roofer fix your roof

How Fast?

How fast can mold spread? If air is constantly moving through your attic and humidity is at a minimum, mold will have difficulty latching onto surfaces and spreading. Mold needs two things to propagate:

  • A moist, porous surface like sheathing, attic insulation , rafters, and drywall
  • Slow or no air movement

Black mold — one of the two kinds that can potentially harm your family — can start germinating within 48 hours of landing on a moist surface exposed to slow air movement. For the first 12 days, mold will not be visible but spread rapidly across surfaces. At around 18 days, mold finally becomes visible as discolorations, black spots, and thin tendrils snaking out across surfaces. If not eradicated quickly (preferably by a mold remediation service, not you), it will spread wherever moisture gives it a chance. Down through your attic into your ceiling drywall, to your interior walls, across molding, doors, and into wood furniture — mold does not stop spreading on its own.

Eliminate Mold

If you spot mold in your indoor living space, work immediately to remove and clean small items that may have mold growing on them. Dry out everything you can, safely using space heaters and fans if needed. In most cases, do not attempt to remove mold from walls and ceilings yourself. The best way to eliminate mold (besides preventing it through annual roof inspections and regular roof maintenance) is to remove the moisture. Fix roof leaks promptly, so mold never gets a chance to settle and germinate.

Some online sources suggest that homeowners spray weak mixes of chlorine bleach and water on mold. Yet your safest, surest path to eliminating existing black and green mold is to bring in a mold removal specialist. Your roofer can handle the roof leak before the mold service does its work.

When you live in a place as beautiful and storm prone as Cape Coral, FL , your roof isn’t just another part of the house. It’s your first and most vital line of defense against Florida’s blazing sun, high humidity, and hurricane season downpours.

Real Results: Recent Roofing Projects in Cape Coral We’ve recently completed several roofing projects in Cape Coral that highlight the scope of our expertise and the quality we bring to each job. One standout job took place in the Rose Garden neighborhood. The homeowner reached out after repeated leaks from their 20-year-old tile roof. After a comprehensive inspection, we recommended a total tear off and reinstallation using high end barrel style clay tiles that match the home’s Mediterranean style. The result? Not only does the roof now provide superior water resistance and wind protection, but it also enhances the curb appeal of the entire property. You wouldn’t believe the transformation, and the homeowner couldn’t be happier. In another project over in Southwest Cape Coral near Cape Coral Parkway, we installed a modern metal roofing system for a homeowner looking to increase energy efficiency.
