Different Types of Roofing Underlayment
Roofing underlayment is a thick sheet-like material that goes between the roof deck and shingles. It is usually 3 ft wide and comes in rolls. Allowing you to lay a long strip of underlayment before your tiles.
Felt – This style of underlayment was the earliest type of underlayment used in roof projects. Felt was dunked in a waterproofing substance in order for it to be waterproof.
Synthetic – This style of underlayment came with the application of rubber and plastics. These are made with mixtures of asphalt in order to create a very waterproofed substance.
How to tell if your Underlayment is Damaged
Seeing if your underlayment is damaged can be pretty tricky because it is sandwiched between your decking and roof shingles. If you have an internal leak in an attic or a ceiling, it’s a sign that the underlayment seal is no longer working. The wood is getting wet and rotting allowing water to leak in. Otherwise, you would have to take your roofing shingles off in order to see the felt layer underneath.
