The Hidden Costs of Improper Insulation in Your Home's Rafter Bays

The Hidden Costs of Improper Insulation in Your Home's Rafter Bays

As a leading Bergen County roofer, we at Mattsson Roofing often encounter homes where the decking appears to be in good condition at first glance. However, deeper inspection frequently reveals hidden issues that can significantly affect the longevity and safety of your roof.

The Problem with Insulation in the rafter bays

At the demarcation point where the insulation was missing, you can clearly see the contrast in the condition of the wood. Where there was insulation, the wood has turned almost black. This discoloration and deterioration occur because moisture over time has saturated the wood. Unfortunately, the trapped moisture means that the wood does not breathe as it should, compromising its structure and integrity.

Why It Matters

If your home has this issue, it's essential to address it immediately. Non-breathable, moist environments in roofing can lead to weakened structures. For instance, when we go to install a new shingle and shoot a nail into the wood, if the wood is no longer strong, it won’t hold the nail. This lack of strength means that the roof does not have the necessary integrity to function properly.

The Solution: Installing a Baffle

One effective solution we recommend is the installation of a baffle. This simple addition allows air to flow properly through the wood, helping to prevent moisture buildup and ensuring the wood can support the necessary roofing materials. This is considering your attic/roof have the proper ventilation system in place.

Important Advice for Homeowners

Due to these issues, we advise against placing insulation in the rafter bays. It might seem like a good idea for extra warmth, but the long-term risks to your roof and, consequently, your home are significant. In some cases, the damage requires us to cut out and replace the plywood decking—a costly process often resulting in a change order for homeowners.
