Common Misconceptions About Wind Damage on Roofs

High winds can damage your roof via leaks, missing shingles, and gutter problems. However, different roofing issues are incorrectly linked to the effects of wind.
Common Misconceptions About Wind Damage on Roofs

In today’s post, your local roofing company, Georgia Roof Advisors, discusses common misconceptions surrounding wind damage on roofs.

Wind-Damaged Shingles Aren’t Always Visible

Heavy and sustained winds can cause shingles to flutter and bend, which leads to the development of creases. Strong winds can break off shingle sections that are then carried downwind. This is common in the areas of the roof that are vulnerable to high winds such as the eaves, hips, and ridges. Shingle failure usually happens at the top of the exposed area below the overlying shingle’s butt end.

Roof affected by wind will most likely show signs of damage like creases, folds, tears, and missing shingles. A shingle that’s just not adhered and doesn’t indicate any of the said signs isn’t affected by wind damage.

Choose a reliable local roofer like Georgia Roof Advisors to ensure you get an accurate assessment of your roof. Immediately perform roof repair on problem areas to prevent further damage.

Shingles With Insufficient Adhesion Is Wind-Damaged

There are different reasons shingle adhesive fails. These include manufacturing deficiencies, improper installation, deterioration and aging, installations on cold weather, adhesive contamination, and thermal cycling. Strong wind forces can lift and remove inadequately adhered shingles, but not all poorly adhered shingles are caused by wind.

Empirical Tests Accurately Indicates a Shingle’s Strength Reduction After a Storm Event

The Standard Test Method for Wind Resistance of Asphalt Shingles or the ASTM D7158 is referred to as a proper and simple method to test a shingle’s strength following a storm event. The method aims to compare field-measured strengths to the rating originally determined by the manufacturer.

Uplift forces must be calculated by the manufacturer using test results from an independent laboratory. However, laboratories capable of performing ASTM D7158 testing are uncommon and can be costly if available. This causes some to calculate the design or intended uplift forces using different methods. There are no alternative tests to ASTM D7158 with similar accuracy, however.

Moreover, when it comes to wind damage assessment, consider the location of damaged shingles, patterns and direction of slopes of unsealed shingles, and the wind direction during the storm.

3-Tab Asphalt Shingles versus Architectural Shingles

Thinking about repairing or replacing a new roof can be confusing, especially when it comes to deciding what kinds of materials to use in the process. Most homeowners want to know the choices available to them. Shingles will likely be part of that choice and, there are numerous options with shingles. There are colors, shapes and overall installation techniques that most people are not aware of. Most homeowners should get a basic idea of the different types of shingles before they dive into the roofing process.

Roof Shingle Categories

Shingles are basically categorized as architectural shingles and 3-tab shingles. Here is a rundown on both of them:

Architectural Shingles

Architectural shingles have different names. They can be called laminate shingles or dimensional shingles. In contrast to more traditional 3-tab regular shingles, architectural shingles are available in varying sizes and shapes. They also have an appearance that suggests proportion, volume, depth and dimension. With an architectural shingle, you can derive the features of an asphalt shingled roof plus acquire added dimension.

3-tab Shingles

This type of shingle is what is associated with traditional asphalt shingles that are commonly used in roofing projects. They are a single tab and are non-dimensional in shape. They are placed flat to a roof’s decking and do bring a clean and neat appearance to a roof line. They are available in a number of different colors.

Differences of Roofing Materials Explained:

Composition:

Both architectural and 3-tab shingles are composed of asphalt as well as fiberglass with a mat type backing, a top layer of granules and adhesives for adherence. The differences between the two have to do with the overall quality and materials. Architectural shingles contain a higher caliber of asphalt in contrast to 3-tab shingles. They also contain an increased number of granules on their surface, plus stronger adhesives and a base that is thicker and tougher. Architectural shingles are also infused with color distinctions that greatly intensify the look of the shingles. Added surface granules increase the chances of preserving this type of shingle for a longer period of time.

In contrast, 3-tab shingles are very flat in appearance, which is due to the fact that the tabs are of the same size and shape and are evenly placed in rows. As with architectural shingles, 3-tabs are available in multiple colors though the colors are less intense in their coloration and texture.

Thickness:

Thickness of the architectural shingles are other factors that differentiate architectural shingles from 3-tab shingles. They are quite a bit heavier and thicker than 3-tabs. A thicker shingle allows for greater endurance and strength and when it comes to wind and other extreme weather conditions, architectural shingles are considerably more durable. Three-tab shingles are weaker, less durable and not as long lasting. They can be subject to damage in of reoccurring bad weather such as hail, and strong winds.

Pros and Cons of Architectural and 3-Tab Shingles

Architectural Shingles Pros:

  • More popular choice of roofing material
  • 50-year manufacturer guarantee
  • Resistance to increased wind speeds (up to 130 mph wind protection)
  • Twice as thick as 3-Tab Shingles, therefore, are more durable and less vulnerable to curling
  • Increased value to a home

Architectural Shingles Cons:

  • More costly (about 20 to 40% more than 3-Tab shingles)
  • Heavier than traditional asphalt shingles which may make them unsuitable for certain structures.

3- Tab Shingles Pros:

  • Lighter and consist of less material
  • Less expensive
  • Used throughout most residential communities because of affordability

3-Tab Shingles Cons:

  • Less thick and often require replacement sooner than expected
  • Flat in appearance rather than dimensional
  • Not quite as popular in use
