Prosperity Roofing & Exteriors -Roofing Glossary

Architectural shingles are laminated asphalt shingles with multiple layers, creating a thicker, dimensional look and improved durability compared to 3‑tab shingles.

Asphalt shingles are the most common roofing material in Texas, made from a fiberglass mat coated with asphalt and mineral granules for weather protection.

Class 3 shingles are impact‑resistant shingles tested to withstand 1.75‑inch steel balls dropped from 20 feet, offering moderate hail protection.

Class 4 shingles are the highest impact‑resistant shingles, tested to withstand 2‑inch steel balls dropped from 20 feet. Many insurance companies offer premium discounts for Class 4 roofs.

Chimney flashing is metal installed around the base of a chimney to prevent water from entering the roof system.

Cracked shingles are shingles that have split due to age, heat, or storm damage, often leading to leaks.

Decking is the wooden base layer of the roof, typically made of plywood or OSB, that supports underlayment and shingles.

A drip edge is a metal flashing installed along roof edges to direct water away from fascia and prevent rot.

Fascia is the vertical board beneath the roof edge that supports gutters and protects the roof structure.

Flashing is metal installed at roof joints, valleys, and penetrations to prevent water intrusion.

Granule loss occurs when the protective mineral coating on shingles wears off due to hail, age, or foot traffic.

Hail bruising is soft, spongy damage to shingles caused by hailstones crushing the asphalt layer beneath the granules.

Impact‑resistant shingles are roofing materials designed to withstand hail and debris impacts, rated from Class 1 to Class 4.

Ice & water shield is a waterproof underlayment installed in vulnerable areas like valleys and roof edges to prevent leaks.

Metal roofing is a durable roofing system made from steel, aluminum, or copper panels, known for longevity, energy efficiency, and excellent hail resistance.

Missing shingles occur when wind or storm damage removes shingles entirely, exposing the roof to leaks.

Nail pops occur when roofing nails push upward through shingles due to heat expansion or improper installation.

A ridge vent is a ventilation system installed along the roof peak to allow hot air to escape from the attic.

A roof valley is the internal angle where two roof slopes meet, directing water toward gutters.

Soffit is the underside of roof overhangs, often vented to allow airflow into the attic.

Storm damage includes hail impacts, wind‑torn shingles, fallen debris, and water intrusion caused by severe weather.

A tear‑off is the process of removing old roofing materials before installing a new roof.

Underlayment is a protective layer installed between the decking and shingles to prevent moisture penetration.

A vent pipe boot is a rubber or metal flashing that seals the area around plumbing vent pipes.

Wind uplift occurs when strong winds lift shingles or roofing materials, potentially causing them to detach.
