By Meyers Roofing Co. – Trusted Roofing Experts Serving Los Angeles and Orange Counties

If you’re planning a roof repair or roof replacement in Los Angeles or Orange County, understanding basic roofing terminology can help you make more informed decisions. At Meyers Roofing Co., we believe that well-informed customers feel more confident and get better results from their roofing projects.

Here are the most common roofing terms every homeowner should know:

1. Shingles

Roof shingles are the outermost layer of your roof and are available in materials like asphalt, wood, metal, and composite. In Southern California, asphalt shingles are especially popular due to their durability and affordability.

2. Underlayment

This water-resistant barrier sits between the roof deck and the shingles. It’s essential for protecting your home from leaks, especially during Los Angeles rainstorms or coastal weather in Orange County.

3. Roof Decking (Sheathing)

Decking is the structural base for your roofing system, typically made from plywood or OSB. It provides a solid surface for attaching roofing materials.

4. Flashing

Roof flashing is thin metal installed around features like chimneys, skylights, and vents to direct water away and prevent leaks—especially important in areas like roof valleys and edges.

5. Drip Edge

A metal strip installed along the roof edges, a drip edge helps guide water into gutters and away from the fascia and home foundation.

6. Ridge

The ridge is the peak where two roof slopes meet. Many homes in Southern California feature ridge vents to allow hot attic air to escape, improving energy efficiency.

7. Valley

Roof valleys channel rainwater off the roof and into the gutters. Proper valley installation is critical for preventing leaks and water pooling.

8. Eaves 

Eaves are the lower edges of a roof that extend past the walls. They’re key for directing water away from your siding and foundation, and often contain vents to improve attic airflow.

Located beneath the eaves, the soffit provides ventilation to your attic and helps regulate moisture levels, which is important for avoiding mold and rot.

The fascia is the board that runs along the edge of the roof and supports the gutters. It also gives your roofline a polished, finished look.

9. Ventilation

Proper roof ventilation extends the life of your roof and improves indoor comfort. Options include ridge vents, soffit vents, and gable vents, all of which are important for homes in the warmer Southern California climate.

10. Ice and Water Shield

Though not as critical in Southern California, an ice and water shield is a waterproof membrane often used in vulnerable areas like roof valleys or under flashing for added leak protection.
