Major home improvements, such as roof replacement, involve making huge decisions. Researching and knowing the parts of your roof can help you make more informed decisions on your project. While it excels at preventing leaks, underlayment is typically an understated roofing component.

What Is Underlayment?

Underlayment is a layer of water-resistant material found between the roof deck and shingles. It protects your roof against moisture, helping keep indoor spaces dry and insulated. You can get it in various types, each with its advantages and disadvantages. 

What Are Your Underlayment Options?

Asphalt-saturated Felt

Asphalt-saturated felt is a paper material impregnated with asphalt for water resistance. It’s a popular and cost-effective type of underlayment. However, it may not be as durable as other options. 

Synthetic Underlayment

A more modern option, synthetic underlayment features synthetic materials such as polypropylene or polyethylene. It offers excellent protection against water damage and lasts longer than asphalt-saturated underlayment. 

Ice and Water Shield

Ice and water shield is an underlayment option with excellent waterproofing capabilities. Professionals usually install it in areas prone to leaks, such as eaves and chimneys. 

Why Is Underlayment Important?

Underlayment gives your home an extra layer of protection against leaks. It keeps water from seeping through shingles and damaging the decking. This component will help you save money on roof and home repair services. It can also help prolong the life of your roof by strengthening its defense against extreme temperatures and moisture. 

With high-quality underlayment, you will notice a reduction on your heating and cooling costs. It improves your home’s insulation, helping it stay cool in summer and warm and winter.
