Designing a roof isn’t as simple as it seems. After all, this is the feature that shields your home from Tennessee’s unpredictable weather, while elevating curb appeal and keeping you and your energy bills comfortable. To achieve these results, there’s quite a bit to take into account when creating the perfect investment.
So, what are the 4 things to consider when designing a roof? Below, our experts at Alvarado Roofing & Construction explain the importance of a strong, well-planned roof, the different types of designs, and the 4 factors every homeowner should weigh before starting a major roofing project. Scroll down to learn more!
Why Is a Good Roof Design Important?
- Protect your structure: Your investment must channel water efficiently and withstand harsh winters and storms, preventing leaks, mold, and costly repairs.
- Improve energy efficiency: With proper ventilation and reflective materials, your roof keeps Tennessee’s humid summers at bay, reducing utility costs.
- Boost property value: A roof that complements your house’s architectural style might improve resale value and, in some cases, even speed up closings.
- Reduce long-term maintenance: The right pitch, materials, and flashing details lower the risk of damage. In turn, you won’t have to perform constant maintenance.
The Main Residential Types of Roof Designs
| Roof Type | Main Characteristics | Pros | Cons |
|---|---|---|---|
| Gable | Two sloping planes meet at a central ridge. | Excellent drainage and classic Southern look. | Vulnerable to uplift in high winds if not braced. |
| Hip | All sides slope inward and meet in a central ridge. | Superior wind resistance and balanced appearance. | Slightly more complex framing and higher labor costs. |
| Dutch Gable | Gable perched atop a hip base. | Adds attic space, plus blends style and strength. | More valleys require extra flashing care. |
| Shed/Skillion | Single sloping plane. | Modern vibe, perfect for solar panels, and great water runoff. | Limited attic and needs a higher pitch for water flow. |
| Gambrel | Two slopes per side (think of a barn roof). | Spacious loft, and provides a nostalgic charm. | Low resistance to heavy snow and high winds. |
| Flat/Low-Slope | Minimal pitch; often on modern homes. | Ideal for rooftop decks or solar panels. | Demands meticulous waterproofing and drainage scuppers. |
The 4 Essential Factors to Consider in Roof Design
1. Tennessee’s Climate and Seasons
- Heavy rainfall: Sevierville averages around 44 inches of precipitation each year.
- Severe thunderstorms & hail: Spring supercells can drive hailstones into shingles, exposing the underlayment.
- High winds & tornado risk: Middle Tennessee’s wind zones require decking and fasteners rated to local code.
- Freeze-thaw cycles: In winter, meltwater can creep under shingles and refreeze overnight, prying them upward.
2. The Structure of Your Home
All residential roof designs should complement your existing architectural style and structure. Let’s say, a contemporary styled house will look better with a flat roof, and a traditional one might benefit from a sloped one.
In terms of the structure, remember the possibility of future additions and other features, like chimneys, skylights, and vents. Similarly, if you are interested in building a porch or solar array, consider the extra weight and attachment points now.
3. Materials of Your Choice
Let’s face it: while you may have a preferred material in mind already, it’s still vital to evaluate whether it benefits you or not. Materials must balance durability, budget, and style. These are the most famous roofing materials in Tennessee, so review their characteristics in detail:| Material | Lifespan | Benefits | Things to Consider |
|---|---|---|---|
| Architectural Asphalt Shingles | 25–30 years | Affordable, wide color range, good mold resistance. | Can lose granules under heavy hail. |
| Metal | 40–70 years | Exceptional wind/hail resilience; readily sheds snow. | Higher upfront cost; requires specialized installers. |
| Synthetic Slate or Shake | 40–50 years | Lightweight elegance of slate without structural reinforcements. | Must select Class A fire-rated products. |
| Clay/Concrete Tile | 50+ years | Timeless Mediterranean look; resists rot and insects. | Heavy, so it often demands roof reinforcement. |
