Your Roofing Terms Glossary For Residential
Roof Replacement In Granite Bay

Learn The Terms Used During A
Residential Roof Replacement

Roofs have many different pieces and types of hardware. While an excellent residential roof replacement company in Granite Bay can help explain what their terminology means, it’s also helpful to have a guide to definitions.

At Lucero’s Roofing, we’ve been working on roofs for a long time and enjoy replacing your roof and letting customers know what’s happening up there.

What Are Some Common Terms Used

Here are some common and not-so-common phrases we often use during a residential roof replacement project.


Your home’s roof has equipment for home ventilation, including your chimney and vent caps. Rain is sneaky and could quickly get through the gaps between your shingles and chimney. Flashing is a metallic piece that goes beneath your shingles in these areas to prevent water from flowing beneath your roof.

Flashing does wear out over time and can be damaged by storms, leading to a leaky roof. Since this layer of metal is mostly below your shingles, it can be tricky to spot issues developing. We suggest asking us to come out to provide an estimate if you are seeing leaks that could come from old flashing.

Roof Decking

Roof decking provides a structure for the rest of your roof and a safe place for roofers to walk on when installing your roof. Decking consists of sturdy planks or sheets of wood that provide a flat, even surface for shingles and underlayment.

Our experts at Lucero’s Roofing will examine your roof and decide if you need to replace or repair roof decking before replacing the residential roof on your Placer County home.


This term is commonly used in flooring, too. Underlayment goes on top of your decking and below your shingles. Underlayment provides additional protection for your home and decking against leaks, water damage, and mold. You’ll learn that underlayment comes in synthetic and felt varieties. Synthetic is more resistant to mold, while felt comes with a lower cost.


A valley is where two parts of a roof meet to form a downward slope. Valleys are essential to roofs to allow water to flow off. It’s also critical to install suitable flashing hardware in the valleys of your roof to keep this area waterproofed and dry.


The shingles on your roof can form raised circular areas caused by excess moisture or gas or even getting hit by hail. Blistering can spread and shorten the lifespan of your shingles. You might see more of this on a poorly ventilated roof.


You might be familiar with the term R-Factor with insulation. The R-Factor refers to the level of thermal resistance. This doesn’t just apply to insulation, though – R-Factor also applies to the many materials used to build your roof, including the underlayment and insulation.

R-factors work numerically, with the highest rating offering the most thermal insulation. Lucero’s Roofing will help you determine what R-Factor your roof requires.

Drip Edge

A drip edge is a metal plate fastened to the roof’s edge. The drip edge protects your fascia and roofline from getting water underneath, which causes damage. A drip edge also helps prevent ice dams.

Ice Dams

While this isn’t a term for roof equipment, ice dams are a big problem! Ice dams occur when snow on a roof is melted, often by an attic leaking excess heat or a sudden change in weather. The snowmelt then begins to drain off your roof but leaves the heated part of your roof and freezes again near the edge. The result is icicles and ice dams.

Ice dams are a problem for a couple of reasons. Ice is rather heavy and can potentially damage your roof and gutters, which aren’t designed to hold much weight.
