One of the worst things for a building owner is roof rot. It might not sound like much of an issue, because you don’t always see it and “out of sight, out of mind”. The problem becomes evident once water spots appear on your ceiling or plaster starts falling off, but at this point, it is past time to start looking for the cause. That is why we are here to not just help you deal with the problem, but also to help you prevent it.

What Do You Need to Know About Roof Rot?

What Causes Roof Rot?

Several things can lead to roof rot, but the three main causes are:

  • humidity due to temperature changes in the attic
  • moisture from the condensation caused by the temperature
  • ventilation problems

So, what exactly is roof rot? Also known as dry rot, roof rot is what happens when there is too much moisture in your attic. Another cause could be a water leak somewhere in your roof, allowing water to seep into your attic. Whatever the cause, our technicians can find it, help you find a solution, and ensure that it won’t happen again.

How To Deal With Roof Rot?

You can repair roof rot if the areas that are affected are not responsible for structural stability. So long as there is not a beam, joint, or flooring, you can try repairs instead of replacement. Before dealing with the damaged wood itself, make sure you find the cause of the problem. You need to fix the leaking roof, poor ventilation, plumbing leaks, or damaged gutter before you can focus on the wood itself.

Repair or Replace Roof Rot?

The repair process starts with removing as much of the damaged wood as possible. The best tool for this is a wood chisel. You can also inject a consolidant into the wood to help reinforce the affected wood that cannot be reached with a chisel. This will help the wood fibers bond with the undamaged wood, to make them strong again. This can be dangerous to do by yourself because not removing all the affected wood could allow the rot to seep deeper into the rest of the wood, eventually causing the same problem. Replacement is a different process as you will need to remove all the wood. You also need to remove three feet of the surrounding wood. Then, you need to remove the plaster, skirting paneling, linings, and ceilings to make sure you got all the rot. Clean all the surfaces and steel pipes in a five-foot radius of the rotted parts and apply a fungicide to all the surface area in that five-foot radius. Replace the wood that was removed with one that has a preservative coating already on it. Lastly, re-plaster and paint, typically with a zinc oxychloride product. This process is very complicated, tiresome, and sometimes a dangerous process that is best left to professionals, so call us today, so you don’t have to stress and worry.

How Can You Prevent Roof Rot?

The best way to make sure that your roof is rot-free is to have regular inspections done. Having a professional come to check your roofing will ensure that any signs of moisture, leaks, or excess humidity, can be identified and evaluated for solutions. Another thing to do is to make sure that you have a proper roof ventilation system. Without this, the moisture from the humidity has nowhere to go, so it will sink into the wood and cause this problem again. Keep track of how your shingles are holding up and make sure that there is no debris on your roof preventing water from running off.
