High winds and sudden spring storms are common occurrences for homeowners in North Texas. It is not unusual to walk out into your yard after a thunderstorm and find a few asphalt shingles scattered across the lawn. When this happens, your roof's primary defense against water intrusion is compromised, leaving the underlayment and decking vulnerable to rot and leaks.
Roofing across the DFW Metroplex, we have seen how quickly a small patch of missing shingles can turn into an expensive interior repair. Whether you are planning a DIY fix or looking to understand the process before calling a professional for roof repair services, knowing the right way to replace missing shingles is vital for maintaining the integrity of your home.
Identifying the Damage and Gathering Tools
Before you begin, you must assess the extent of the damage. If you are missing more than a handful of shingles in one area, or if the shingles are missing across multiple slopes of the roof, you may have significant wind damage that warrants a professional roof inspection. If the damage is localized, you can proceed with a repair.
To do the job correctly, you will need a few specific tools: a pry bar (often called a 'snake' bar in the industry), a hammer, a utility knife, roofing nails, and a tube of roofing cement. You will also need matching shingles. Matching can be difficult in North Texas because the intense UV rays fade shingles quickly; even if you have the original brand and color, the new shingles will likely look darker than the weathered ones currently on your roof.
The Step-by-Step Replacement Process
The goal of a shingle replacement is to restore the 'shedding' effect of the roof. Asphalt shingles work by layering over one another so that gravity pulls water down and off the eaves. If a shingle is installed improperly—even by half an inch—it can create a 'backwater' effect where moisture gets trapped underneath.
- Choose a clear, calm day. Working on a roof in high winds is dangerous, and shingles are easier to handle when they are warm and pliable.
- Use the pry bar to carefully lift the tabs of the shingles in the row directly above the missing pieces. You must break the sealant strip without tearing the shingle.
- Locate and remove the nails from the damaged shingle remnants. You will also need to remove the nails from the shingle directly above the one you are replacing, as those nails usually pass through the top of the damaged shingle.
- Slide the new shingle into place, aligning it with the existing courses to ensure the water-shedding pattern remains consistent.
- Drive new roofing nails into the nail line. In our region, we highly recommend using six nails per shingle to better withstand the straight-line winds common in North Texas.
- Apply a small dab of roofing cement under the tabs to help the new shingle seal against the one below it, especially if you are performing the repair during the cooler months.
Why Texas Weather Makes Repairs Tricky
In Denton County and the surrounding areas, our roofs endure extreme temperature swings. The heat can cause shingles to become 'cooked' and brittle over time. When you attempt to lift a brittle shingle to nail a new one underneath, the old shingle may crack or snap. If this happens, your small repair has just grown in size.
Additionally, if your shingles were blown off by a significant wind event, there is a high probability that the surrounding shingles have suffered 'seal failure.' Even if they are still attached, they may no longer be adhered to the roof. As a veteran-owned company, we prioritize honesty: sometimes a simple repair is the right move, but if the roof is old and the sealant has failed across the slope, a full roof installation may be the only way to truly protect your home.
When to Call a Professional Contractor
Safety should always be your first priority. Steep pitches, two-story heights, and the presence of power lines make roof work hazardous for the average homeowner. Furthermore, if your missing shingles are the result of a recent storm, you should consider the insurance claims process. Attempting to repair the roof yourself before an adjuster arrives can sometimes complicate your claim.
A professional roofer will not only replace the missing shingles but will also check the flashing around chimneys and vents, which are common failure points during high-wind events. If you are uncomfortable on a ladder or if the damage looks extensive, it is always safer and more effective in the long run to hire an expert with the right safety gear and experience.
