From harsh weather protection to insulation, your home’s roof provides a durable barrier against the outside elements. Because of its role, the structure is constructed to last for several decades thanks to several key components. Here are some of the main parts installed by professional roofers.

4 Common Parts of a Roofing System

1. Fascia

These are the wooden, aluminum, plastic, or vinyl boards that are located around the roof line to hold the gutters in place. They are constructed to prevent moisture from infiltrating a home’s interior, which can trigger mold and mildew. Roofers say if water from ice dams and clogged gutters becomes trapped behind the fascia, holes and other damage can occur.

2. Flashing

Panels of aluminum or galvanized metal are installed around chimneys, roof valleys, and decks to channel water flow away from the entire roofing system. Flashing is also placed around skylights and vent stacks to redirect water flow. Damaged flashing can trigger leaks that can trickle down into a home’s attic and other interior rooms.

3. Soffit

Roofers place this siding under a roofing system’s overhang. Available in aluminum, vinyl, and wood, soffit helps maintain ventilation between the roof and a house’s attic. The ventilation is needed to prevent moisture accumulation, which leads to mold. Soffit also keeps unwanted squirrels, raccoons, and insects from invading your home. Old or damaged soffit may impede airflow and bring on mold and mildew.

4. Underlayment

Another key part of the roofing system, this underlayment is installed under a roof’s decking and provides a number of protective barriers. Underlayment guards shingles from excessive resin from the decking and keeps water from forming underneath shingles. It also provides a fire-resistant barrier within the decking area. Improperly installed or damaged underlayment can allow ice dams to form, trap water underneath shingles, and cause leaks.
