When dealing with your roofer in Columbia, MO, it’s helpful to understand roofing terms. This way, you and your contractor will be on the same page.

The following are important terms with which to familiarize yourself.


Roof decking refers to the roof’s foundational structure. The decking is like the skeleton of your Columbia, MO roofing. It’s usually constructed with wood, steel, concrete, among other materials. The decking is present between a roof’s joints and trusses.

If you notice any roofing Columbia, MO mold, holes, buckling, or sagging, it indicates the decking is damaged.


A home’s flashing is the steel sheeting that sits around roof edges. Flashing components of roofing in Columbia, MO channel water away from the roof’s surface area. It also stops leaks from occurring in roof joint areas. It can be placed around chimneys, skylights, vents, and other areas.

If shingles near the flashing are darker or distorted, it’s a sign of damage. If this is the case, you’ll need a roofer in Columbia, MO.


Fascia refers to the wooden boards on the edge of a house’s roofing in Columbia, MO. It functions as a connection point for drainpipes and gutters. It also helps to complete a home’s appearance. Broken, faded, or peeling paint on fascia means it’s time for a fix-up.


A roof’s hip is the connection point between two roof slopes. It covers the top of the ridge down to the eaves. As they are on the edge of your Columbia, MO roofing, they often need more shingles to protect this area.


The ridge is the top roof slope connection point that spans the entire rooftop. The highest point of the ridge is called the peak.


A Columbia, MO roofing valley is the concave area where roof slopes meet. They can be made with lead, fiberglass, concrete, or aluminum.


The gable is the triangular piece at the spot where the roof and the sidewall meet.

Frieze Board

The frieze board often creates a transitional zone between the soffit and siding or two different siding boards.


A soffit is the piece of decorative Columbia, MO roofing under the eaves that give it a completed look. They can be placed beneath arches, balconies, roof eaves, and other places. Soffits are not only attractive, but they are also functional. They are designed to protect rafters from the weather.

A soffit can show signs of wear and tear from being in the elements. If they appear faded, broken, damaged, or crumbly, then roofing companies in Columbia, MO advise that you repair or replace them.


Roof trusses support your roofing Columbia, MO rafters. The trusses are a major load-bearing component of any roof structure. For this reason, it is best not to move them once they have been secured.

Trusses have been developed for many centuries to function as they do today and are thus quite a feat of engineering.

Drip Edge

Drip edges are designed to channel rainwater away from the roofing Columbia, MO fascia, and other underlying components. The drip edges are placed at the edges of a roof in an L shape. They have tiny, flat steel rims that bend away from the fascia, thus directing water away.

If you see rust on the drip edges, you need a roofer in Columbia, MO to replace them.
