Dealing With Flat Roof Rot

Dealing With Flat Roof Rot

Also known as dry rot, roof rot is a condition that is ugly, unhealthy and costly to repair. That’s why as a homeowner, you’ll want to avoid it at all costs. Left unchecked, it breaks down roofing materials, eating away at wood and making it dry and crumbly until the structural integrity of the roof deck and sheathing become compromised.

It is very risky to ignore roof rot because it spreads rapidly — as much as 10 feet in one year — and can lead to extensive leaks and even total roof collapse. As your trusted roofer, Chase Roofing LLC, discusses what you need to know about this condition and how to prevent its occurrence.

What Causes Roof Rot?

Roof rot is caused by a wood-eating fungus that thrives in environments that have excess moisture. While there are several ways in which this moisture can originate, the main culprit is usually an attic that’s too hot and poorly ventilated. This leads to higher humidity levels, which exposes  the wooden components of your roof to moisture damage and eventually, roof rot. It only takes as little as a 20% moisture level for the rot to progress and begin sending fine, microscopic strands of gray fungus into surrounding fibers in the wood.

Other causes of roof rot include:

  • Ponding problems, especially since flat roofs have an inadequate or compromised slope

  • Clogged gutters, faulty downspouts, leaky troughs, basically anything that causes poor roof drainage

  • Damaged shingles or roof membranes that allow water to seep in and reach wooden structures

Common Signs of Roof Rot

  • Sagging roof

  • Water stains on the ceiling or down interior walls

  • Cracked seals around chimney, vent pipes and other roof structures

  • Discoloration on the fascia below the roof line

Preventing Roof Rot

Here are some preventative measures you can follow to prevent roof rot and avoid serious problems:

  • Make sure your attic receives adequate ventilation and that it remains at a moderate temperature year-round.

  • Schedule a professional roofing inspection at least twice a year and also after every major rainstorm in your area to check for standing water on your flat roof.

  • Repair damaged membrane or shingles and replace damaged caulking around chimneys and vent sas soon as you notice them.
