When choosing the right underlayment for your new roofing project there are many brands and products available to you, as the consumer. WeatherSeal Roofing being a proud member of GAF's Certified Contractors network, we offer a full range of GAF underlayment's, also referred to as roof deck protection. We put together a breakdown and comparison of the best GAF has to offer.

‍

Types of Underlayment:

Generally, there are two popular types of underlayment's, Felt and Synthetic. Felt is manufactured by saturating paper or fiberglass mat with asphalt and typically come in 15 LB thickness configuration or 30 LB. Synthetic underlayment is typically manufactured from woven or spun polyethylene or polypropylene and comes is a wide variety of thicknesses.

Full synthetic underlayment's are typically more expensive than their felt counterparts, however, synthetic underlayment has been proven to be superior to felt in many ways, which include; synthetic underlayment's repel heat better on hot summer days, are less ridged in cold weather and less likely to crack or break, tend to stay fastened and more secure in high wind events, are made of stronger material, lighter than felt, and safer for the roofers due to their slip resistance.

At WeatherSeal Roofing we provide GAF full synthetic underlayment's on all our projects as they have been proven to be more durable and superior to felt.
