Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

    It is manufactured from polypropylene and polyethylene, which are used make a wide variety of other consumer products. Synthetic underlayments offer a number of advantages over roofing felts, such as tear resistance, UV resistance, and they don’t wrinkle when exposed to moisture like roofing felt. When it first began appearing on roofs in the mid-1980s, the multiple advantages made it a premium-price  product. But, as synthetic underlayment’s popularity and production has increased, the price has come down to become comparable to 30-lb. felt, and it will likely be the predominant roof underlayment in the years to come. Popular brands include RhinoRoof®, Grace Tri-Flex®, and Titanium UDL30®.

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
