TYPAR Surround S.R. Roof Underlayment and Warrior Roofing 30lb felt roof protection are both top-rated products according to online reviewers. As of 2015, TYPAR's product scores five out of five possible stars with Amazon.com reviewers, and Warrior Roofing receives 4.8 of five stars from Home Depot customers.
Reviews state that the TYPAR Surround S.R. Roof Underlayment is a high-quality product. Reviewers note that it is exceptionally durable and able to withstand rain and high winds without tearing. The underlayment is made of synthetic fiber. It is stronger than felt underlays and provides more water resistance, while being lighter and easier to carry onto roofs during installation. Some reviewers negatively comment that the light weight of the underlayment makes it susceptible to being blown off the roof during installation if it isn't secured immediately.
Warrior's 30lb felt roof protection is constructed of asphalt-saturated material, and reviewers state that it offers superior waterproofing over other brands of felt underlayment. The heavy duty design makes it easy to install, as the product lays flat and wrinkles less than other, lighter brands. The roof protection's slip-resistant surface and clear alignment markings also assist with installation. Some reviewers feel the product tears too easily.
