New Roof Installations: The Application of Underlayments

New Roof Installations: The Application of Underlayments

Weather in Delaware is anything but predictable. Moisture in the form of snow, hail and hurricanes can give your roof a beating.

Roofing that is inspected yearly and kept up with regular maintenance and repairs will usually make it through the wet season just fine. Added insurance, however, is always a good thing. Thus, the importance of applying a roofing underlayment in new roof installations.

The Application of Underlayments in Roofing Installations

The Application of Underlayments in Roofing InstallationsUnderlayment is just a fancy term for the layer of sub-roofing material that is put on the structure of your home before the roofing materials, i.e. shingles, shakes, tiles, are laid. The underlayment creates an added barrier to protect the roof structure from moisture, and in some cases, fire. Both water and fire damage can lead to unsightly destruction of your roof and costly repairs to the exterior and interior of your home.

The two most common types of underlayment used in roofing today are felt and synthetic, both materials having specific advantages and drawbacks.

Felt paper is the most commonly used underlayment with new roof installations. The main advantage of using felt paper is that it’s an inexpensive option. However, felt paper cannot be left exposed to the elements for very long before it wrinkles and traps condensation between the roof structure and the backside of the paper.

More costly underlayments include a variety of synthetics such as:

  • Fiberglass
  • Polyester
  • Polypropylene

These roofing materials protect against water damage but also tear- and heat-resistant. Some synthetic underlayments can be left open to the elements for up to six months, in case your roofs installation is delayed for any reason.

Proper Roofing Installation Is Key To A Long Lasting Roof

Ask your Delaware roofing contractor about the underlayment he uses to protect your roof, and request that a certain type of material be used if you have a preference. Remember, investing in quality materials is a smart move in the long term so do your research upfront and get your roof installed the right way!

    Agreed – quality materials from the underlayments to the shingles will make a huge difference in the longevity and durability of a roofscape.

    It’s amazing how often I get called to repair a roof repair because of the previous repair contractor not using the proper underlayment. So the leak gets fixed but in time, the wood rots and needs replaced again anyway.

    Underlayments act as a vapor barrier to keep that moisture from wreaking havoc on the wood surface and is critical in your roof’s longevity.

      I once re-roofed a house where there was felt on one side, and no felt on the other; and both sections appeared to be in identical (pristine) condition. Just makes me wonder if felt paper is as critical as is imagined. Of course I like the idea of using good-quality materials & felt would be one aspect, but it just made me wonder.
