4 Roofing Terms Every Homeowner Should Know


This means filling a joint with a high-grade construction sealant called mastic or asphalt cement to prevent leaks. Caulking is also a term important in plumbing. Having a good, durable sealant for your roof reduces the risk of leaks during the stormy season.

Edging Strip

The edging strips are boards nailed along eaves and rakes. They provide secure edges for re-roofing with asphalt shingles.


You may have never heard of a roof underlayment, but it does a lot of work every day to keep your roof in shape. The underlayment is a waterproof layer underneath the shingles that serves as a moisture barrier. There are three types of roofing underlayment: asphalt saturated felt, synthetic underlayment and rubberized asphalt underlayment.

Asphalt saturated felt is made from natural plant fibers, polyester and asphalt. It was the preferred roofing underlayment material until homeowners started preferring synthetic materials. Synthetic underlayment has a fiberglass addition that provides superior durability. Lastly, rubberized asphalt is the most expensive type of roofing underlayment but has higher percentages of asphalt and rubber polymers.

Drip Edge

A drip edge is a non-corrosive, non-staining material used along eaves and rakes to allow water run-off to drip clear of underlying construction. The drip edge extends the life of your fascia and prevents rainwater from sliding down your siding. With a drip edge installed during roof replacement, excess water will easily shed off your roofing system and fall safely into the gutters.
