Buckling shingles are a common issue that homeowners like yourself may encounter as your roof gets older. There are a few reasons why this happens to roofs. Factors such as weather and humidity play a big role and when you think about the St. Louis and Springfield weather, it really starts to make sense. It doesn’t just affect the appearance of the roof though, it also affects the longevity and effectiveness of the roofing system itself.
Recognizing what causes asphalt shingles to buckle is important to remember when it comes to maintaining the structure of your home and preventing any future damage. This blog aims to help homeowners like yourself understand the various factors that can lead to shingle buckling, empowering you with the knowledge to address and prevent this issue effectively.
Common Causes of Shingle Buckling
There’s plenty of factors that can cause roof shingles to buckle, but understanding them will help you get an idea of when you should check up on them. Below, we’ll dive into the common causes that lead to this issue:
Moisture and Roof Deck Exposure
One of the main culprits behind shingle buckling is the exposure of the roof deck to excessive amounts of moisture. Wood decks are particularly susceptible to absorbing moisture, which can cause the wood to swell and distort. This leads to buckling shingles directly above the deck itself.
When exposed to humidity and water, wood decks can absorb moisture, especially if they are not adequately sealed or if they have been exposed during any time in the roof installation process.
– Impact of Humidity: In areas with high humidity, the risk of moisture absorption increases, and if the wood is not allowed to dry properly before shingle installation, it can retain moisture that will sit and contribute to buckling as conditions change.
A Wet Underlayment
The felt underlayment beneath shingles is important to a strong, healthy roof. However, it can really be a source of problems if it becomes wet during installation: If that felt underlayment absorbs moisture during or even after the roof installation—mostly due to rain or dew—it can expand and push up on the shingles laid above it. As a result of wrinkles in the underlayment, buckling occurs.
Inadequate Ventilation
A home with poor attic ventilation can lead to a buildup of hot, moist air in the attic space. If your home seems to have a ventilation problem, it can not only affect the roof itself but it can also cause those shingles to buckle. Trapped moist air as we know from above, can cause condensation on the roofing components and this unwanted moisture then leads to the problems that promote buckling.
Roof Sheathing Issues
Roof decking or sheathing should be spaced properly so that it can allow for the natural expansion and contraction of the wood. Not having adequate spacing can lead to compression and ultimately that buckling that we are looking to avoid. This just proves that proper installation and maintenance of your roof sheathing are so important.
Improper Installation Techniques
Improper shingle installation is another common issue that can lead to buckling. Asphalt Shingles that are not nailed down correctly or are misaligned can fail to lay flat. Since they are not able to properly expand and contract with temperature changes, this can also cause them to buckle.
Use of Subpar Materials
The quality of materials used in roofing significantly impacts their longevity and how it resist issues like buckling. Using shingles or any roofing materials that are of low quality or not suited to the local climate can lead to faster deterioration and buckling. These cheaper, low-quality materials may not withstand the environmental stresses and over time, they quickly start to deform.
How Weather Conditions Affect Your Roofing
Weather conditions are another factor that plays a significant role in the health and longevity of roof shingles. Of course moisture has a lot to do with everything but there are other important conditions that have their own effect.
Extreme Heat
In hot climates, shingles can expand excessively. When the temperatures drop, these expanded materials may not return to their original state, leading to potential buckling and other structural issues. Not to mention, the intense UV rays from sun exposure can also degrade asphalt roofing over time, making it more brittle and less flexible.
Extreme Cold
In colder regions, shingles can become brittle and more susceptible to damage from ice and snow. Ice dams, in particular, can be a severe threat as they tend to force water underneath. This lifts the shingles from the roof and creates an entry point for more moisture to enter and as we’ve learned, that moisture and water are not friends of your roof.
Storm Conditions
It’s no secret that wind, hail, and heavy rain have the ability to physically damage shingles. High winds can lift shingles from the roof, breaking the seal that holds them down. While hail can cause punctures and fractures in the shingle surface causing you to need a full replacement from the storm damage if things get too bad.
Aging and Wear from Environmental Exposure
Over time, environmental exposure naturally degrades roofing materials. As shingles age, they lose their protective granules and the oils within them dry out. This natural degradation process reduces their flexibility and resilience, making them more likely to warp or buckle under stress. This is also where a roof sealing treatment may come in handy.
– Environmental Exposure: Constant exposure to pollutants, chemicals in the rain, and fluctuating weather conditions can also accelerate their aging process. Each of these factors can incrementally weaken the shingles, increasing the likelihood of damage over time.
Preventative Measures and Solutions
To ensure the longevity of your asphalt roof and mitigate the risk of buckling, there’s several different steps you can take to help maintain its integrity and functionality and of course, avoid roof buckling.
Regular Roof Inspections
Regular roof inspections are so important for early detection of potential issues that could lead to shingle buckling. In fact, it’s recommended to inspect your roof at least twice a year and after any severe weather events, especially those where hail and high winds have occurred. These inspections can help identify early signs of wear on your roof, such as missing, buckling, or damaged shingles that might otherwise go unnoticed. It’s always better to spot these things early, as letting the problem sit, may cause some big-time damage to your roof.
Proper Roof Maintenance
– Clean Debris: Keep the roof surface clean from debris, leaves, and branches. All of which can retain moisture and contribute to shingle deterioration. If you’re someone who doesn’t mind getting on your roof, we suggest a small hand blower or even a broom to keep debris off. As anytime you’re on your roof, make sure safety is your number one priority.
– Clear Gutters and Downspouts: Ensure that your gutters and downspouts are free of blockages. Any water buildup can seep under shingles and lead to buckling.
– Replace Any Damaged Shingles: Promptly replacing damaged or missing shingles can prevent further damage to the roof structure and underlying materials. Not to mention that it just looks better. Keeping a healthy roof means an overall better-looking home.
Addressing Installation and Material Quality
The quality of materials and the accuracy of the installation process are fundamental in preventing roof issues. With your roof, opt for high-quality, durable roofing materials that are appropriate for your local climate and environmental conditions. This choice helps ensure the its resilience against weather-related stress.
Don’t forget to make sure you also hire a certified and experienced roofing contractor. Just make sure they adhere to best practices and manufacturer guidelines during installation or any repair to avoid future problems such as buckling.
Enhancing Roof Ventilation
Improving attic ventilation can significantly impact the roof’s ability to manage moisture and temperature. Installing adequate soffit and ridge vents can facilitate the proper flow of air in the attic. This helps to keep components such as the roof deck dry and at a consistent temperature, all of which prevent moisture accumulation and buckling of shingles.
When to Contact a Professional
Recognizing when it’s necessary to bring in a professional for roof repairs or replacement is crucial for maintaining the safety and integrity of your home. Here’s how you can identify those serious issues and choose the right contractor for the job.
Signs That You Need Roof Repair or Replacement
Not all roof issues require professional intervention, but certain signs indicate that it’s time to call in the experts:
– Serious Shingle Buckling: If large sections of your roof are visibly buckled, this can signify underlying issues that require professional assessment and repair.
– Leakage: Water stains on ceilings or walls inside your home often indicate roof leaks that might have spread beyond the visibly damaged area. This situation typically calls for professional repairs.
– Age of Roof: If your roof is nearing or has surpassed its expected lifespan, and you’re noticing widespread issues like buckling or missing shingles or even a leak where the single needs to be patched, it might be more cost-effective to consider a replacement rather than repeated repairs
