What Are The Components of a Residential Roof?

What Are The Components of a Residential Roof?

Bob Harvey Roofing • April 12, 2022

As a homeowner, it is important to understand the components of your residential roofing system. The roof protects the entire structure of the home and knowing what every component is responsible for is essential for its proper upkeep and maintenance. Bob Harvey Roofing explains


The Architectural Parts of a Pitched Roof

Despite their many shapes and structures, roofs have a standard set of architectural parts. These include:


  1. Roof plane: Also known as the field of the roof, the roof plane is essentially the flat surface of the roof.
  2. Ridge: The point where the two roof planes meet is known as the ridge of the roof.
  3. Valley: The structure where two roof planes connect in an inward projection is the valley.
  4. Dormer: Projecting out of the roof, this structure provides space for a window or light to enter the home.
  5. Abutment: Found commonly in smaller homes, the abutment is where the roof face connects to the wall of the house.
  6. Hip: The point where two roof faces connect in an outward projection is known as the hip.
  7. Gable: The triangular structure below the point where two roof planes connect is the gable.


The Anatomy of a Residential Pitched Roof

Apart from the architectural structures, there are layers in a roof that provide it with strength and durability.


Shingles

These are easily the most commonly found and recognizable components of a roof. While wood and slate shingles were the preferred choice in olden times, asphalt shingles are more utilized in the last century. Available in a variety of colors, asphalt shingles come in the following styles:


  1. Traditional or 3-tab shingles
  2. Laminate or architectural shingles
  3. Designer shingles
  4. Solar reflective and thermal emissive shingles
  5. Mock slate shingles


Flashing

Flashing is the material roofers use to transition between surfaces. Flashing is usually a thin metal sheet that is installed around several vertical features on a roof including chimneys, plumbing vents, and dormers. This helps protect the interiors of the home from water damage that can otherwise seep through the shingles, decking, or underlayment of the roof.


Underlayment

For further protection, roofing professionals recommend adding an underlayment, which is a fabric-like barrier, onto the decking of the roof. The underlayment helps with:


  1. Protecting the shingles from resin released by the decking
  2. Avoiding the seepage of water
  3. Preventing ‘picture framing’, which is a phenomenon that occurs with the contraction and expansion of wood panels


Ice and Water Protector

Ice and water protectors are placed beneath the shingles to prevent roof damage caused by harsh winds, snow, and ice. In areas that are prone to hurricanes, tornadoes, or high snowfall, it is recommended to install ice and water protectors across the entire surface of the roof deck for greater durability.


Roof Frame

The roof frame, also known as the roof truss, is the wooden structure or skeleton that holds all other components of the roof. There are several local and national quality standards that contractors must adhere to when building the roof frame. It is then completely covered with thin wooden panels known as roof sheathing or decking.


Factors to Consider When Selecting a Roofing System

If you are looking to embark on your roofing project, there are several factors to consider:


  1. Cost: Depending on the area you live in, there are certain materials you must use to safeguard your roof. However, if you are looking to save costs, asphalt shingles are an excellent choice.
  2. Warranty: It is recommended to always review the warranty document and understand your coverage closely before making a decision.
  3. Maintenance: Even though the roof is considered a sturdy component of your home, it is advised to conduct routine maintenance at least twice a year for the best protection.

Introduction Utah homeowners know that the state’s weather doesn’t play fair—scorching summers, heavy snowfall, sudden spring downpours. But what many don’t realize is how all that weather quietly takes a toll on one crucial system: your roof drainage. And when that system fails? It’s not just about clogged gutters—it’s about thousands of dollars in hidden damage to your roof, walls, foundation, and even your health. Roof drainage problems in Utah are more common than you might think, especially in older homes or those with flat or low-slope roofs. From standing water that rots decking and forms ice dams, to overflowing gutters that erode your landscaping and crack your foundation, poor drainage can destroy your home from the top down. In this article, we’ll break down the signs of drainage failure, the specific risks Utah homes face, and how to protect your biggest investment. You’ll learn what causes drainage issues, how to spot early warning signs, and the smart, affordable upgrades that can save you from costly repairs. What Is Roof Drainage? And Why Utah Homes Need It Working Right When most Utah homeowners think about roof maintenance, they picture shingles, flashing, or maybe even attic insulation. But one of the most overlooked systems—yet arguably one of the most critical—is your roof drainage. Without it, all the snowmelt, rain, and runoff from Utah’s wild weather has nowhere to go… except into your home’s structure. A roof drainage system is designed to move water efficiently off the roof and away from your home. It includes: - Gutters and downspouts - Roof pitch or slope - Flashing and drip edges - Downspout extensions or underground drainage pipes The goal is to prevent water from pooling on your roof, running behind siding, or collecting around your foundation. In Utah’s climate, that’s no small task. You’re dealing with ice dams in January, thunderstorms in July, and even snowstorms in April. Many older homes along the Wasatch Front—including Roy, Bountiful, and Ogden—were built with minimal or outdated drainage systems. If your home can’t shed water properly, you’re at serious risk of roof leaks, wood rot, and even structural damage. Quick Takeaways - Roof drainage problems in Utah are a leading cause of hidden home damage. - Signs include overflowing gutters, stained siding, and attic mold. - Common causes: clogged gutters, flat roofs, and poor attic ventilation. - Drainage issues can lead to foundation cracks, energy loss, and mold. - Preventative steps include gutter guards, downspout extensions, and insulation upgrades. - Bob Harvey Roofing provides expert inspections and drainage solutions across Utah. Conclusion Utah’s dramatic climate makes roof drainage a critical part of your home’s defense system. As we've explored, roof drainage problems in Utah can quietly lead to serious damage: rotting roof decking, mold in your attic, cracked foundations, and escalating energy bills. The good news? Most drainage issues are completely preventable. Whether it's cleaning your gutters, adjusting your downspouts, or upgrading insulation, small fixes can prevent big problems. At Bob Harvey Roofing, we know how to build and repair systems that handle Utah's extreme conditions—from ice dams to monsoons. We don’t just fix damage—we help you prevent it. Don’t wait until you see water stains. Book your roof drainage inspection today. FAQs 1. What causes roof drainage problems in Utah homes? Utah drainage issues often result from clogged gutters, poorly sloped roofs, or short downspouts. Snowmelt and monsoons can easily overwhelm these systems. 2. How do I know if my gutters are affecting my foundation? Look for water pooling near the base of your home, musty basements, or cracks in concrete walls. 3. Are ice dams a sign of roof drainage failure? Yes. Ice dams prevent water from flowing off your roof. This causes leaks, rot, and long-term damage. 4. Can poor roof drainage increase my energy bills? Absolutely. Moisture from drainage issues can ruin your insulation, forcing your HVAC system to work harder. 5. How often should I clean my gutters in Utah? At least twice a year—spring and fall. More often if you live near trees. 6. What are the best gutter options for Utah weather? Seamless gutters with guards are ideal for handling snow, rain, and debris. 7. Is roof drainage repair covered by homeowners insurance in Utah? It depends. Sudden damage is usually covered. Neglected maintenance is not. 8. When should I call a roofing contractor about drainage issues? Call if you see overflowing gutters, staining, or interior moisture. A professional inspection can catch problems early.
