10 Signs of Excellent Roof Performance


When it comes to judging the value of a home, few people think of looking at the roof – but it plays such a huge role in the overall health of your home. The roof’s appearance and performance affect so much about your life: energy bills, the cleanliness of the air you breathe, your home’s internal temperature, your children’s health, and the list goes on.

How do you know that your roof is performing well? In this blog post, we’ll dissect the details. We’ll cover:

1. What we mean by a high-performance roof
2. How to look at your roof’s structure
3. 10 signs of a high-performing roof
4. How to know if your roof is done well

What is a high-performance residential roof?

A high-performance roof is one that’s engineered to be eye-catching, durable, energy-efficient, and resilient against the elements. It is economical and creates a healthy environment for your home life no matter what Mother Nature may throw your way. If done well, it can potentially add renewable energy generation to any construction project.

The definition of a perfect roof is different for every climate zone. For instance, in arid areas, roofs should be designed to deflect extreme heat (metal roofs are a great option), while in colder regions, roofs should be structured to prevent the accumulation of snow and ice. But largely, all high-performance roofing systems, residential and commercial, have a few common characteristics:

Residential roofing: What are the characteristics of a good roof?

1. Reduced repairs and maintenance: A high-performance roof means less stress about potential damage from environmental factors and lower long-term roof maintenance costs.

2. Protection from the elements: A well-constructed roof provides better protection against weather events, staying intact and habitable with minimal damage during storms and adverse weather events.

3. Energy efficiency: High-performance roofs can help maintain a comfortable interior temperature, reducing the need to run heating or cooling systems excessively, thus saving costs. During extreme weather events, a good roof can reduce household dependency on the electrical grid created by short-term surges.

4. Optimized service life: High-performance roofs are built to last, with materials and designs that extend the roof's service life, reducing the need for premature replacements and regular repairs.

5. Environmental benefits: Properly engineered roofs reduce greenhouse gas emissions and improve air quality. A good roof can even mitigate the urban heat island effect by lowering the surrounding outdoor air temperature.

Understanding roof structure

Before we go into the signs that tell you that your roof is performing well, it’s important to understand the parts of a roof. The diagram below clearly details the different parts of a residential roofing system, so you can communicate better with your Apex roofing contractor during your free roofing inspection – and understand the signs that your roof is in good condition.


10 signs of excellent roof performance

Whether you are considering roof maintenance, or just inspecting your new roof replacement, here’s a list of 10 signs that will tell you your roof is performing well:

1. No leaks: Leaks are the beginning of most common roof problems. The absence of leaks is a great sign that your roof is doing its job. When your roof keeps your home dry, you avoid mold and maintain a healthy internal environment.

2. Sturdy shingles: If you have shingle roofing, closely inspect the pieces. Solid roof performance means shingles that are uniform in appearance, perfectly aligned, and free from cracks, buckling, or missing pieces.

3. Efficient ventilation: A well-ventilated roof helps regulate indoor temperatures and prevents moisture buildup (the beginning of your roof’s decline). If your attic stays cool during summer and dry during winter, your roof's ventilation system is working effectively.

4. Comfortable insulation: Temperatures should be even throughout your home in different rooms, and the walls, floors, and ceiling should be warm and dry to the touch. Good insulation reduces the amount of heat that escapes from your home, so lower energy bills are a sign that your roof is doing well.

5. Gutter reliability: Gutters play a crucial role in directing water away from your roof and foundation. They should run parallel to your roofline without sagging or overflowing. Check that there is no standing water, overflowing, or persistent leaks.

6. Growth resistance: There should be no moss, algae, or lichen on your roof, as that can compromise its structural integrity. Regular cleaning and roof maintenance will ensure that.

7. Intact flashing: Roof flashing is found at the joints between the roof and vertical surfaces like front walls, parapets, chimneys, vents, and other openings. It is used to divert water away from vertical surfaces. Damaged or deteriorating flashing can be a source of leaks.

8. Structural integrity: Your roof should maintain a level appearance with no sagging or dips. Any structural issues, like sagging, require immediate attention.

9. Granule conservation: If you have asphalt shingles, they should retain their granules, which protect against UV damage. If you notice excessive granule loss or bald spots on shingles, it's time to assess their condition.

10. Lower energy bills: Consistently lower energy bills are a sign that your roof is insulated well, free of structural damage and leaks.

How to know if your roof is done well

The most obvious sign that your roof is done well is the aesthetics. All the parts should fit together well: shingles and tiles should be perfectly aligned and have a uniform color and appearance. Gutters should run straight. The smallest details should be in place: fasteners, drip edge flashing, eaves, the little things you don’t notice, because good roof engineering should be invisible.

Responsible roofing specialists will also leave a clean job site. They should gather all debris and inspect the roof at the end of each workday, showing care and attention to detail. If your roofing contractor is communicative, transparent, and happy to explain what they’re doing, that’s a sign that your job is going well.

Newer roofs also often come with warranties. A robust warranty is a strong indicator of your roof’s quality and its expected performance.

How to maintain your roof’s performance

Keeping an eye on your roof prevents minor issues from escalating, prolongs its life, and ensures it continues to effectively protect your home or building from the elements. It does take a bit of effort, but it pays off in the long run. Here are a few roof maintenance tips:

1. Regular roofing inspections: Scheduling regular inspections by Apex roofing inspectors is an effective way to ensure your roof continues to perform optimally. For yourself, keep an eye out for signs of damage such as missing shingles, cracks, or leaks. Do this especially after hurricanes and severe weather.

What makes a roof strong?

A combination of quality materials, expert craftsmanship, and regular maintenance make a roof strong. It involves durable shingles or tiles, robust underlayment, and a solid frame to withstand environmental stresses like wind, rain, and temperature changes.

How do I know my roof is stable?

The most obvious indicator of your roof’s stability is its resilience against harsh weather and the sturdiness of the parts that make up your roof. For a more accurate picture, get a professional inspection. With Apex, roof inspection costs are nil.
