Understanding the language of roofing can make all the difference when you’re facing repairs or replacement for your home in Durham, NC. Whether you’re speaking with a contractor, reviewing an estimate, or reading a warranty, knowing basic roofing terminology will help you make more informed decisions, avoid confusion, and ensure you’re getting the service you expect.
Here’s a comprehensive guide to essential roofing terms every Durham homeowner should know—especially before starting a roofing project.
1. Shingles
Shingles are the outermost layer of your roof, serving as its primary barrier against weather. They’re typically made of asphalt, wood, metal, or composite materials. In Durham, asphalt shingles are the most common due to their affordability and durability in variable weather conditions.
2. Underlayment
Underlayment is the protective barrier installed between your roof deck and shingles. It provides waterproofing and an added layer of defense against moisture intrusion. Popular options include felt paper and synthetic materials.
3. Flashing
Flashing is thin metal—usually aluminum or galvanized steel—used to direct water away from critical roof areas like chimneys, skylights, and vents. Proper flashing is key to preventing leaks and water damage in Durham’s frequent storms.
4. Fascia
The fascia is the board mounted along the edge of your roof, typically where gutters are attached. It helps support the roof structure and protects it from water infiltration.
5. Soffit
Located beneath the overhang of your roof, the soffit helps ventilate the attic by allowing air into the roof system. This ventilation plays a critical role in regulating temperature and preventing moisture buildup—essential in Durham’s humid summers.
6. Ridge and Ridge Vent
The ridge is the highest point where two roof slopes meet. A ridge vent is installed along this peak to allow warm, moist air to escape from the attic. Proper ridge ventilation promotes airflow and extends the life of your roof.
7. Valley
A valley is the V-shaped channel formed where two sloping roof sections meet. It’s one of the most leak-prone areas, so it must be properly sealed with metal flashing or a waterproof membrane.
8. Decking (Sheathing)
The decking or sheathing is the structural base of your roof, usually made of plywood or oriented strand board (OSB). It supports the underlayment and shingles and must be in good condition before any new roofing is installed.
9. Ice and Water Shield
An ice and water shield is a self-adhesive waterproof membrane installed in vulnerable areas like eaves and valleys. While Durham isn’t prone to heavy snow, the shield adds extra protection during rare ice events or driving rain.
10. Drip Edge
A drip edge is a metal flashing installed along the edges of the roof to guide water into the gutters and prevent it from seeping under the shingles. It’s a small detail with a big impact on preventing water damage.
11. Nail Pops
Nail pops occur when roofing nails begin to protrude through shingles. They can result from expansion, contraction, or improper installation. Left unaddressed, nail pops can lead to loose shingles and leaks.
12. Blistering and Granule Loss
Blistering is caused by moisture trapped in shingles during manufacturing or due to poor attic ventilation. Granule loss refers to the erosion of the protective outer layer on asphalt shingles, often seen after a storm. Both are signs that repairs—or even replacement—may be necessary.
13. Eaves
The eaves are the edges of the roof that extend past the walls of the home. They help direct water runoff away from your siding and foundation, especially when paired with gutters.
14. Roof Pitch
Pitch refers to the angle or slope of your roof. It affects drainage, material choice, and labor costs. Steep-pitched roofs shed water better and may last longer but can be more expensive to install.
15. Roofing Square
A roofing square equals 100 square feet of roofing area. Contractors often use squares instead of square feet when quoting roofing materials and installation.
