Missing or Curling Shingles: What It Means and What to Do

Missing or curling shingles almost always mean your roof’s protective layer has been compromised, and rain, wind, or UV damage is working on the decking underneath right now. This is not a cosmetic problem. Every day a shingle is gone or lifting at the edges, water has a way in. Your local Brennan Roofing team can inspect the damage, put the repair price in writing before anything starts, and get the roof watertight again.

What’s Happening

When shingles go missing or start curling at the edges or center, the waterproofing layer on your roof has broken down in at least one spot. Water doesn’t need a big opening – it needs any opening. The underlayment, decking, and anything below it are now exposed.

Shingles are designed to lie flat and overlap in a pattern that sheds water off the roof and into the gutters. When one lifts, curls, or blows off entirely, that pattern breaks. Wind-driven rain finds the gap. So does morning condensation that never fully dries. Over time – sometimes a short time, depending on how much rain you’re getting – the wood decking beneath starts to absorb moisture. Soft decking is expensive to replace. A missing shingle caught early is not. The gap between those two outcomes is usually a single inspection.

Why It Happens

Age and UV Breakdown

Asphalt shingles have a lifespan, and heat speeds up the clock. UV exposure dries out the asphalt binder that keeps shingles flexible. When that binder goes, shingles get brittle, crack along the edges, and start to curl upward at the tabs or cup downward in the center. If you’re seeing this pattern across a large section of the roof rather than in one isolated spot, age and sun exposure are almost certainly the cause. A roof approaching or past its rated life with widespread curling is telling you it’s done.

Improper Installation

Shingles installed without enough nails, with nails placed too high on the shingle, or without proper starter strips will lift and curl earlier than they should – sometimes within a few years of install. If your roof is relatively new but you’re already seeing curling or shingles blowing off after moderate wind, installation error is worth investigating. A trained inspector can tell the difference between wear and a workmanship problem by looking at nail placement on the shingles that are still in place.

Poor Attic Ventilation

Heat and moisture trapped in an attic will cook shingles from below. If your attic runs extremely hot in summer or you notice frost or condensation on the rafters in winter, ventilation is likely inadequate. Shingles that curl on the warm or sunny side of the roof, especially on a newer install, often point here. The fix isn’t always just new shingles – fixing the ventilation is part of the solution or the problem comes back.

Storm or Wind Damage

A single storm can tear shingles loose or lift them far enough that the seal strip underneath never re-seats. If you noticed missing shingles after a wind event, hail storm, or heavy rain, that’s your timeline. Look for granules collecting in the gutters or downspout discharge – that’s mineral coating knocked loose from impact. Shingles with granule loss are weakened even if they look like they’re still in place. What you can see from the ground is rarely the complete picture.

What to Do Right Now

• Stay off the roof. Walking on damaged shingles can break more of them, and working at height without the right equipment and training is genuinely dangerous. Leave the visual inspection to the ground or let a trained technician handle the rooftop assessment.
• Photograph what you can see from the ground. Use your phone to zoom in on the damaged area. Note where on the roof it is – which slope, near a valley, close to a vent or chimney. This information helps the technician come prepared.
• Check your attic for signs of water entry. Look for water stains on the rafters or decking, soft or discolored wood, or daylight coming through. If you see any of these, the damage has already reached the structural layer. Note it and mention it when you call.
• Clear the area below any visible leak path. If there’s a room below the damaged section, move anything you don’t want water-damaged and put a bucket down as a precaution until the repair is done.
• Call now rather than after the next rain. Missing or curling shingles don’t heal on their own, and the next storm makes the situation worse. The earlier a technician gets eyes on it, the more options you have. Call (361) 320-9467 – a live person picks up, around the clock, no voicemail.

How We Fix It

When your local Brennan Roofing technician arrives – background-checked, in uniform, inside the window we gave you – the first thing they do is a full inspection of the damaged area and the surrounding field of shingles. Missing shingles don’t always travel alone; the ones nearby are often compromised too. The technician checks the decking for moisture, looks at the underlayment condition, and assesses nail placement and ventilation if the pattern of damage suggests an underlying cause.

Once the inspection is done, you get a written price before any work starts. That’s not a policy we bend – it’s how every job works at Brennan Roofing. The repair itself typically involves removing the damaged shingles and any compromised underlayment, inspecting or replacing sections of decking if water has reached it, and installing new shingles from manufacturer lines including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. The right material for your roof is explained plainly so you can choose.

Most shingle repairs are completed in a single visit. All work is covered by the 365-Day Done Right Promise – a written guarantee for a full year. If the repair fails within that time, we come back and make it right at no charge. The services that handle this: Roof Repair and, where the damage is more widespread, Roof Inspection to establish the full scope before pricing begins.
