As a seasoned roofer, just as you have your trusted material suppliers, you likely have your preferred method for installing roofing underlayment. Among the three main types available, let’s delve into a comparison between synthetic roofing felt and tar paper. Given the pivotal role a roof plays in safeguarding a home, the quality of the underlayment is paramount.
Understanding Synthetic Roofing Felt versus Tar Paper
Synthetic roofing felt is crafted from fiberglass fleece or polyester, treated with a waterproofing agent typically comprising modified asphalt. Serving as a moisture barrier, it repels water from the roof deck, ensuring it drains off without seeping into the home. Resilient against various weather conditions—from scorching heat to stormy climates and seasonal changes—synthetic roofing felt continues to safeguard the home even in the aftermath of storm damage. Not only does it prevent wood stains from resin leakage, but it also enhances fire ratings when used beneath shingles. Furthermore, its installation offers heightened safety for roofers, featuring a gripping surface that minimizes slipping or falling risks.
In contrast, tar paper shares similarities with roofing felt in shedding water, often used interchangeably due to their similar functions. However, tar paper exhibits lower resistance to wind and sun exposure compared to other underlayment systems. Being organic, it is susceptible to quicker deterioration under humid and hot conditions, unlike synthetics. Despite its regular use, tar paper poses reliability concerns during installation, prone to tearing easily and challenging to walk on. While it may fulfill its function if left undisturbed, there remains a risk of eventual rotting and cracking over time.
