Quick Answer

When roof shingles are missing after a storm, the critical first step is to safely assess the scope of the damage. Many homeowners make the mistake of either ignoring minor damage or attempting permanent repairs without proper safety precautions. A temporary repair with roofing tarps can prevent further water intrusion, allowing time for a professional inspection and more permanent solutions.

The Problem

You wake up after a fierce storm—wind howling, rain lashing—and a quick glance at your roof reveals the unsettling truth: missing shingles. Whether it's just a few asphalt rectangles scattered in the yard or a wider swath of exposed underlayment, missing shingles are more than just an aesthetic issue. They are a direct breach in your home's primary defense against water, UV radiation, and severe weather. The immediate concern is water intrusion, which can lead to rotten decking, compromised attic insulation, damaged ceilings, and even mold growth within hours or days if left unaddressed. The problem isn't just the missing shingle itself, but the vulnerability it creates for your entire roofing system and, by extension, your home.

How It Works

Your roof is a complex system designed to shed water and protect your home. Asphalt shingles are the outermost layer, working in tandem with underlayment, flashing, and proper ventilation. Each shingle is designed with an adhesive strip (tar line) that, once heated by the sun, seals to the shingle below it, creating a watertight barrier. During installation, shingles are also nailed to the roof deck, typically with four nails per shingle. The overlap of shingles ensures that water flows down and off the roof, rather than penetrating the structure.

Strong winds, especially those exceeding 50-60 mph, can create uplift pressure under the shingles, particularly along eaves, rakes, and ridges. If the shingle's adhesive seal has degraded over time due to age, UV exposure, or previous hail damage, or if the shingles were improperly installed with too few nails or nails placed too high, the wind can lift and tear them away. Once a shingle is dislodged, the underlying shingle is exposed, and more importantly, the roofing felt or synthetic underlayment can become exposed. This underlayment is not designed for prolonged direct exposure to the elements and can degrade quickly, allowing water to saturate the roof deck and potentially leak into your attic or living space. Understanding this layered defense system highlights why even a few missing shingles are a urgent problem.

Step-by-Step Fix

SAFETY NOTE: Always prioritize your safety. If you are uncomfortable on a ladder or roof, or if the roof pitch is steep, wet, or icy, do not attempt this repair yourself. Call a professional immediately. Wear slip-resistant shoes, use a sturdy ladder, and have someone spot you.

1. Assess the Damage Safely – Begin by evaluating the situation from the ground.

   • Walk around your house to identify all areas where shingles are missing or damaged. Use binoculars if necessary to get a closer look at higher sections of the roof. Note the approximate size of the damaged area and the number of shingles missing. Look for not only outright missing shingles, but also bent, creased, or loose shingles that could detach in the next storm.
   • If the roof involves a steep pitch (over 6/12), multiple stories, or visible structural damage, skip DIY and call a roofing professional immediately.

2. Gather Your Materials – Collect everything you'll need before climbing.

   • This includes a sturdy ladder, heavy-duty tarp (large enough to generously cover the damaged area and extend beyond it), utility knife, hammer, roofing nails (1-inch typically), 2x4 lumber or furring strips, roofing cement or sealant, safety glasses, heavy-duty gloves, and slip-resistant footwear. Have your phone handy for emergencies.

3. Clear Debris and Prep the Area – Ensure a clean surface for the tarp.

   • Carefully climb onto the roof if it's safe to do so. Remove any loose debris (branches, leaves, old shingle pieces) from the damaged area. Be gentle to avoid further damage to surrounding shingles. Avoid walking directly on the exposed underlayment or any areas where the roof deck might be softened by water.

4. Position the Tarp Over the Damage – Proper placement is key for water diversion.

   • Unfold the tarp and drape it over the damaged section. The goal is to ensure the tarp extends several feet beyond the damaged area in all directions, especially upslope, to prevent water from getting underneath. The top edge of the tarp should ideally be tucked under an existing row of shingles or positioned as high as possible upslope from the damage.

5. Secure the Upslope Edge First – Prevent water from getting under the top edge.

   • Roll the top edge of the tarp around a 2x4 piece of lumber or furring strip. This creates a secure, weighted edge. Place this weighted edge over the intact shingles above the damaged area. Nail through the 2x4 and the tarp into the roof deck approximately every 12-18 inches. Use roofing cement under these nails for an extra seal. This creates a watershed that directs water over the tarp.

6. Extend and Secure the Tarp Downslope and Sides – Create a tight, wind-resistant seal.

   • Smooth the tarp tightly downslope and over the sides of the damaged area. At the bottom (eaves side) and sides (rake ends), roll the tarp around additional 2x4s or furring strips as you did for the upslope edge. Nail these strips securely into the roof deck, again applying roofing cement underneath the nails for a better seal. The tarp should be taut and wrinkle-free to resist wind. For extra security, you can apply strips of roofing cement along the edges of the tarp that lie directly on existing shingles.
   • If high winds are expected, consider adding more furring strips and nails, or even running strapping over the tarp and securing them to fascia boards to prevent it from flapping.

7. Inspect Your Work – Double-check all connections.

   • From a safe vantage point, visually inspect the tarp. Are there any loose edges? Is it pulled tight? Is it adequately covering the entire damaged zone? The goal is to create a temporary, water-resistant barrier until professional repairs can be made.

8. Document for Insurance – Take photos for your claim.

   • Take clear, well-lit photos of the missing shingles, the damaged area, and your temporary tarp repair. Include wider shots that show the overall roof and home, as well as close-ups of the specific damage. This documentation will be crucial when filing an insurance claim.

Common Causes

• High Wind Speeds: The most common culprit. Sustained winds or strong gusts can lift and tear off shingles, especially those along edges or areas with less adhesion.
• Aged or Deteriorated Shingles: As asphalt shingles age (typically beyond 15-20 years), the adhesive strips lose their effectiveness, granules wear off, and the shingles become brittle and more susceptible to wind uplift.
• Improper Shingle Installation: Common errors include using too few nails, nailing above the tar line (high nailing), or failing to apply adequate adhesive in cold weather, which prevents the shingles from sealing properly.
• Previous Storm Damage: Hail storms can bruise or crack shingles, weakening them. Even if not immediately apparent, this damage makes them more vulnerable to being blown off in subsequent wind events.
• Poor Ventilation: Inadequate attic ventilation can lead to excessive heat buildup, prematurely aging and curling shingles, making them more prone to wind damage.
• Building Code Violations: In some high-wind zones, specific nailing patterns or shingle types are required. If a roof wasn't installed to these standards, it's more susceptible.

Common Mistakes

• Ignoring Minor Damage: Even one or two missing shingles can lead to significant water damage over time. Don't assume a small problem isn't urgent.
• Delaying Temporary Repairs: Water can seep in quickly. The longer you wait to tarp the area, the higher the risk of extensive interior damage and mold growth.
• Walking on Damaged or Wet Roofs: This is extremely dangerous and can cause further damage to the roof, especially if the underlying decking is softened by water.
• Improper Tarp Installation: Simply throwing a tarp over the area without securely fastening it on all sides and rolling the edges around lumber will likely see the tarp blow away in the next gust of wind, providing no protection.
• Using Insufficient Fasteners: Relying on just a few nails or lightweight staples will not hold a tarp in place during strong winds. Heavy-duty roofing nails driven into 2x4s are essential.
• Not Documenting the Damage: Failing to take comprehensive photos and videos before and after your temporary repair can hinder your insurance claim process.

Cost & Time Breakdown

Tips & Prevention

• Regular Roof Inspections: Periodically (at least once a year, and after every major storm) inspect your roof from the ground with binoculars. Look for curling, cracking, missing granules, or loose shingles.
• Keep Gutters Clean: Clogged gutters can cause water to back up under shingles, especially in colder climates where ice dams can form, leading to premature deterioration.
• Trim Overhanging Branches: Trees too close to the roof can cause abrasion, drop heavy debris, and become a direct hazard during storms.
• Ensure Proper Attic Ventilation: Good ventilation extends shingle life by preventing excessive heat buildup in the attic, which can prematurely age the asphalt.
• Understand Shingle Warranty: Know your shingle's wind rating and warranty terms. Some warranties are voided if shingles are not installed to manufacturer specifications.
• Consider Shingle Upgrades: If you live in a high-wind area, consider investing in architectural or designer shingles, which often have higher wind resistance ratings and better adhesive properties than 3-tab shingles.

When to Call a Professional

You should call a licensed roofing professional if you notice extensive damage beyond a few missing shingles, if you see visible damage to the roof deck itself (soft spots, sagging), or if there's any evidence of water actively leaking into your attic or home. Professionals have the necessary safety equipment and expertise to safely assess steep or high roofs. If the storm damage is widespread across your roof, a professional can properly inspect for collateral damage like hairline cracks or impact points that might not be immediately visible to an untrained eye. Furthermore, dealing with insurance claims for significant roof damage often goes smoother with a professional's detailed assessment and documentation. Any uncertainty about the safety or scope of the repair means it's time to call in the experts to prevent further damage or personal injury. Do not attempt to work on main structural components or complex flashing around chimneys or skylights if you are not experienced.
