The Warnings Signs Of Rotted Roof Decking And What To Do Next

It is never a good sign when you notice a water spot forming on the ceiling that is only getting bigger, especially when it is accompanied by the overwhelming smell of mold. The probabilities are that you have a leak in the roof and rotted roof decking is one of the most probable suspects. One of the most regular issues found in the event of a roof tear-off is rotted roof decking.

Roof Decking – What Is It?

Roof decking is the groundwork of a roofing system that is connecting the roof to your home. It is the base that is laying on top of structural trusses that cover the rafters and also support the weight of your roofing shingles. The majority of roof decking comprises of plywood composite (also referred to as OSB – oriented strand board) or plywood. Even though it isn’t noticeable, roof decking is essential to the structure of any home. And if your roof decking is rotting and not able to support the weight of your roof, it can result in substantial structural problems.

What Are The Causes Of Rotting Roof Decking?

The number one culprit is water. Since roof decking comprised of wood composites or wood, it is especially susceptible to water damage and rotting once it is exposed to excess or sustained moisture continuously. Water can seep into the roof and various ways. It can enter through:

  • Worn out and old roof shingles
  • Overflowing spouts or gutters
  • Torn flashing around a chimney
  • Snow accumulation or ice dams during Winter
  • Rising heat and excessive humidity in the attic
  • Inadequate roofing ventilation

All these elements can be the cause for water slowly making its way into the roof system and cause rotted roof decking. Once you notice a leaking roof, it must be repaired as soon as possible.

Failing to repair a leaking roof can cause damage to the home’s structure, mold, water damage, and even fire once it touches electrical wiring.

What Are The Warning Signs Of Rotted Roof Decking?

One of the regular signs that a roof’s decking is compromised is a water leak. Water leaks can cause spots or leaks on the ceiling, cracked paint, stains on interior walls or peeling wallpaper. Inspecting the attic may uncover water stains on the insulation or rafters and even light passing through the gaps in the roof. If not addressed, it could result in mildew or mold developing in the ceilings, walls, and insulation. Another sign to look out for is a sagging roofline or ceiling, which may be an indication of severe issues with the roof’s decking that can warp or lead to a wavy or bowed ceiling and roofline.

Replace or repair?

Rotted roof decking is not something that is repairable. It must be replaced altogether. The longer you wait to get it done, the more issues it can develop, resulting in costlier repairs and extensive mildew and mold, which can impact your health as well.

Have You Checked the Under-Deck Roof?

Other parts of your home like the deck require checking too. Make sure the under-deck ceiling remains waterproof to keep the space underneath it warm and dry. Repairing the ceiling can be a straightforward process. Consider this underdeck ceiling system that is designed to be watertight and easy to install.
