Understanding The Importance Of Roofing Underlayment
The question of whether underlayment is important is a simple one to answer. Roofing underlayment is a critical precautionary barrier that helps preserve the life of the overall roofing system after your shingles. Determining which specific type of underlayment is best for a project deserves a more detailed answer. There are many factors to consider when selecting a roof underlayment such as, climate, ease of use, code requirements such, the primary roofing covering material’s requirements, decking, individual preference and cost.
Generally speaking, roofing felt is a felt paper that is soaked in asphalt and other water-resistant compounds to produce a membrane. Of course, it is a bit more technical, but this is the basic idea behind how felt works sold in either. Felt is commonly sold in either 15# or 30# rolls measuring 36 inches wide. Long ago a 15# roll actually weighed 15 pounds, but over the years that has changed.
Synthetic underlayment was developed as a felt replacement. By weaving together polypropylene and polymer, a water resistant and vapor resistant underlayment was created. This new underlayment is lighter and stronger than its predecessor. To decide which underlayment is the optimum choice for your project, you first must understand the actual uses of underlayment and what they can and cannot do:
- Water resistant (not waterproof)
- Protection from resins in the decking that can be damaging the asphalt shingles
- Vapor protection
- Temporary protection in the event of storm damage
Not every roof needs the best underlayment available on the market and not every budget can afford it. A standard asphalt shingle installation does not require the same vapor protection that might be needed for a metal or slate roof, but a steep roof installation might be safer with better walking surface provided by some synthetic underlayment. A common misconception by homeowners is that underlayment is waterproof and that their roof will leak without it. While underlayment is resistant to water, it is not self-sealing, so water can penetrate at every nail hole. So which underlayment is better for your application?
If you are on a tight budget the best choice for your roof might be 15# felt. Felt has been used for generations in Atlanta and has served its purpose well. Is there a better solution than felt for most roofs? Sure, there is but felt is a great choice. Also, felts offer a great fire rating and are slow to burn.
One of the main barriers to using synthetic underlayment for roofing contractors is the cost is higher per Sq. Ft. than traditional felt. However, companies have recently introduced new products that offer great durability and competitive prices. A major benefit felt offers is a great fire rating and it is slow to burn. One of the main barriers to using synthetic underlayment for roofing contractors is the cost is higher per Sq. Ft. than traditional felt. Some of the major benefits to synthetic underlayment are:
- Incredibly lightweight
- Safer for roofers to walk on while installing shingles
- Stands up to high winds in the event shingles are being blown off
- Both water resistant and vapor resistant
- Great for metal roof applications
- Lays flatter on the roof decking which prevents the appearance of wrinkles that appear where felt is used.
