Terms To Know For Collin County Roof Replacement Projects

When you are facing a McKinney, TX roof replacement project, it can be important to understand the contractor’s terminology. That way, you don’t misunderstand what is being said, and you can effectively communicate your desires and expectations.

The roof is one of the most important features of your home because it is all that stands between you and the elements. Failure to take immediate measures can result in moisture getting inside the house and the need for roof replacement.

Here at Phillips Home Improvements, we’ve created this list of the most commonly used roofing terms. With these terms in your vocabulary, you’ll be better able to communicate with potential roofers.

Essential Roof Replacement Terms

These are the six most commonly used roof replacement terms you should know before you begin looking for a reliable roofing contractor.

1. Roof Deck

The roof deck or “sheathing” is the plywood surface to which the shingles are attached. It is mounted to the roof joists and is one of the topmost sections of the house. When it is in good condition, the roof deck should be straight and true. However, if the shingles leak, the deck can absorb moisture and start to sag or droop. If this occurs, you may need a roof replacement. This process involves tearing off the old shingles, replacing the roof deck with undamaged plywood, and reshingling the house to prevent moisture infiltration.

2. Fascia

The “fascia” is the exterior, horizontal board along the edge of the roof rafters. It protects the house and gives the roof overhang its shape. The fascia provides an attachment point for gutters, downspouts, and soffits. Fascia trim prevents moisture from reaching the rafters from the side. It is usually made of the same material as the siding of the house.

3. Flashing

Roof flashings are pieces of protective metal that surround any roof penetrations, such as the chimney, air vents, or skylights. They are often made of aluminum and act as moisture barriers to prevent rain or melting snow from dripping into the house from around the roof penetration. Although most flashings are made of sheet metal, they may also be composed of bituminous-coated fabric, plastic, or other waterproof materials.

4. Roof Truss

A roof truss is a support structure that supplements a building’s rafters. It is a framework of timber that bridges the wide space above a room and connects the roof to the outside walls of the structure. Using cross-bracing, it balances all lateral (or side-to-side) forces against each other while pressing downward only on supporting walls.

5. Underlayment

Underlayment is a sheet of synthetic or asphalt-saturated material that builders apply to a roof deck to protect it from rain, melting snow, and other moisture. It is the secondary layer of protection just beneath the shingles. In addition to weatherproofing the roof, it also helps insulate the building against heat loss.

Underlayment is a sturdy barrier capable of protecting the roof by itself from bad weather during the installation process, prior to shingle attachment. Moreover, it supplements the shingles to help the roof adhere to building codes and meet Class A fire ratings. If the shingles above it suffer damage from tree limbs or other impacts, it acts as the home’s moisture barrier.

6. Valley

A roof valley is where two downward-sloping roof surfaces meet to form a horizontal intersection. It is the opposite of a roof’s peak, which is the roof’s pinnacle. Gravity draws rainwater and melting snow to the roof valley. Because they are so vulnerable to collecting moisture, they require a particular flashing to protect them against leakage.

Such flashings are typically at least 26-gauge galvanized steel. They should be at least 24 inches wide. Flashings should also be compatible with the roofing system and be properly installed by a proven roofing professional.

Valley flashings can be V-shaped or W-shaped. The first mimics the shape of the roof valley itself and permits rain to drain along its inner edge smoothly. W-shaped flashings have a crimp at the center that makes them look like a W. This gives them two channels along which the water can travel.
