When a storm blows through Wisconsin, it can leave more than just fallen branches in its wake, especially if you have asphalt shingles installed. One of the most common roofing issues homeowners face is missing shingles. Whether it’s due to strong winds, hail, or natural wear and tear, missing shingles can compromise the integrity of your roof, leading to leaks, structural damage, and expensive repairs if it’s not addressed quickly.
In this guide, we’ll walk you through why shingles get blown away, what happens when they do, and how to replace them.
Why Do Roof Shingles Go Missing?
Understanding why shingles go missing can help you take preventative measures to protect your home. Here are the primary reasons shingles may get blown off your roof:
High Winds and Storm Damage
Wisconsin experiences a range of weather conditions, including high winds, heavy snow, and storms that can rip shingles right off your roof. Shingles that were already slightly loose or improperly installed are particularly vulnerable to being torn off.
Age and Wear
As shingles age, they lose their flexibility and protective granules, making them brittle. Over time, this natural deterioration weakens the adhesive and nails holding the shingles in place, increasing the chance of them being blown away.
Poor Installation
Improperly installed shingles, whether it’s due to incorrect nailing, improper sealing, or low-quality materials, are much more likely to come loose. If your roof wasn’t installed by an experienced professional, it might be more prone to shingle loss.
The Effects of Missing Shingles on Your Roof
You might think that a few missing shingles aren’t a big deal, but even a small gap in your roof’s protection can lead to major problems. Here’s what can happen if missing shingles aren’t replaced quickly:
#1 Makes Your Roof Vulnerable To Leaks
Once shingles are missing, water can seep into the exposed underlayment and decking, eventually making its way into your attic or living space. This can result in mold growth, insulation damage, and water stains on the ceiling. Over time, persistent leaks can weaken drywall, leading to expensive interior renovations and potential health hazards due to mold.
#2 Missing Shingles Can Weaken The Roof’s Structure
If water penetration continues unchecked, it can weaken the wooden structure of your roof, leading to rot and expensive repairs. Over time, this can compromise the integrity of your home’s framework. Severe structural damage may even require partial or full roof replacements, which can be significantly more expensive than a simple shingle repair.
#3 Increased Energy Costs
Your roof acts as an insulator, helping to regulate indoor temperature. Gaps from missing shingles can allow heat to escape in the winter and hot air to enter in the summer, increasing your energy bills. This additional strain on your heating and cooling systems can reduce their lifespan, leading to expensive replacements sooner than expected.
#4 Increases The Possibility Of Further Shingle Loss
Once one shingle goes missing, it creates a chain reaction. The surrounding shingles become more vulnerable to wind uplift, leading to further damage over time. Without prompt repairs, you risk exposing larger sections of your roof, accelerating wear and making your home more susceptible to extreme weather conditions.
How To Replace Missing Roof Shingles
If you notice missing shingles, it’s important to act fast. Here’s how you can identify and repair/replace the missing shingles on your roofing system:
#1 Assess the Damage
Before starting, inspect your roof from the ground or use a ladder to determine how many shingles are missing. If the damage is extensive, it’s best to call a professional roofer to assess the situation. Pay close attention to areas around chimneys, vents, and roof valleys, as these spots are more prone to leaks and further deterioration.
#2 Gather Your Tools and Materials
If the initial inspection doesn’t make you wary of major roof damage, you can proceed with handling the replacement of one or two shingles that are damaged or missing, However, we only recommend this if you have some experience in roofing. If that’s not the case, hiring a roofing company is a good option.
To replace missing shingles, you’ll need:
Replacement shingles (Matching your existing ones. Generally, there are some extra shingles left in the bundle after roof replacement. This is where they come in handy)
- Roofing nails
- Hammer
- Flat pry bar
- Roofing adhesive or sealant
- Utility knife
- Safety harness (for high or steep roofs)
#3 Remove the Damaged Shingles
Use a pry bar to carefully lift the shingles above the missing one. This will expose the nails holding the damaged shingle in place. Remove the nails and gently pull out any remaining shingle fragments. Be cautious not to damage surrounding shingles while prying, as this could create further vulnerabilities in your roof.
#4 Install the New Shingle
Now that the area is clean, it’s time to put the new shingle in place. Follow these steps:
- Slide the replacement shingle into position, aligning it with the existing shingles
- Nail it down using roofing nails in the designated nail strip
- Ensure the nails are securely fastened but not overdriven, as this can damage the shingle
- For best results, use four to six nails per shingle, depending on the manufacturer’s recommendations and wind exposure in your area
#5 Seal and Secure The Asphalt Shingle In Place
Apply a small amount of adhesive or a sealant under the edges of the new shingle to create a strong seal. Press down firmly to ensure a secure bond. This will help prevent wind from lifting it in the future. If possible, complete the installation on a warm day, as shingles are more flexible and easier to work with in moderate temperatures.
#6 Inspect Your Work
Once installed, check that the shingle sits flush with the surrounding ones. Ensure all nails are properly covered and sealed to prevent water penetration. If you’re uncertain about the work you’ve done, consider having a roofing professional inspect it to ensure longevity and durability.
When to Call a Professional Roofer
While minor shingle replacement can be a DIY job, there are situations where professional assistance is necessary:
Widespread Damage: If a large portion of your roof has missing or damaged shingles, a full inspection and repair by a roofing expert is advisable.
Leaks or Water Damage: If you notice water stains on your ceiling or attic, the issue may be deeper than just missing shingles.
Steep or High Roofs: Climbing onto a steep roof can be dangerous. Professional roofers have the proper safety equipment and expertise.
Older Roofs: If your roof is nearing the end of its lifespan, a full roof replacement may be more cost-effective than repeated repairs.
