The underlayment is an unseen yet important part of any roofing system, and is the component that must not be skimped or overlooked. In today’s post, your local roofers at Diamond Roofing Specialists, Inc. explain how underlayment works with a complete roofing system.
Underlayment is the layer of material that sits right under the outer layer, and works as a redundancy measure in case the outer layer is punctured or damaged. This is why parts of a building such as exterior walls and foundation slabs require underlayment. On roofing systems, the underlayment is the layer that goes over the decking, right under the outer layer of material such as asphalt shingles, sheet metal or tiles, among others.
The main purpose of underlayment is to protect the decking and underlying layers of the roof. Being made from timber and processed wood products, these components are vulnerable to rot, mold growth and other kinds of damage caused by trapped moisture. Additionally, it helps preserve the condition of the decking. Given that it can be used for a second installation, it can help reduce the cost of your next roofing replacement.
When planning for a roof replacement, your roofer may offer more than one type of underlayment. Here’s a quick comparison:
