Quick Answer

Missing roof shingles after a storm leave your home's protective layers exposed to the elements, making it highly susceptible to water infiltration and subsequent interior damage. A prompt, temporary solution involves covering the damaged area with a waterproof tarp to prevent immediate leaks. For a permanent repair, you'll need to carefully remove any remaining damaged shingle pieces, prepare the surface, and install new shingles, ensuring they are properly nailed and sealed to match the surrounding roof and withstand future weather.

The Problem

You wake up after a powerful storm – high winds, lashing rain, maybe even hail – and something looks… different. A quick glance at your roof reveals the unsettling truth: sections of shingles are gone. Not just a loosened tab, but entire shingles, exposing the dark underlayment or even the bare plywood decking beneath. This isn't just an aesthetic issue; it's a gaping vulnerability in your home's primary defense against the elements. Rainwater no longer sheds efficiently but can now seep directly into your attic, compromising insulation, staining ceilings, and potentially leading to dangerous mold growth or structural rot. Even if a leak isn't immediately apparent, continuous exposure to UV rays and moisture will degrade the exposed underlayment rapidly, escalating a minor repair into a major, expensive problem.

How It Works

Your roof is a complex system designed to shed water and protect your home. Asphalt shingles, the most common roofing material, are manufactured from a fiberglass mat coated in asphalt and granular minerals. They are installed in overlapping courses, with each shingle tab typically secured by four nails driven through the common bond. The overlap, combined with gravity and the shingle's inherent water resistance, directs water down and off the roof. An adhesive strip, activated by solar heat, helps seal the shingles together, creating a wind-resistant barrier. Below the shingles, an underlayment (often asphalt-saturated felt or synthetic material) acts as a secondary water barrier, providing minimal protection if shingles are lost. Beneath that is the roof decking, typically plywood or OSB, which forms the structural base. When strong winds, frequently accompanied by gusts exceeding 50 mph, lift the edge of a shingle, the wind can get underneath, creating uplift pressure. If this pressure exceeds the shingle's adhesive bond and the holding power of the nails, the shingle can tear free, sometimes taking pieces of the underlying shingle or underlayment with it. Once one shingle is dislodged, adjacent shingles become more vulnerable, potentially leading to a cascade effect. Hail can also weaken shingles, causing granular loss or cracks, making them more susceptible to wind damage later.

Step-by-Step Fix

1. Safety First – Assess the situation safely before climbing.

• Stay Grounded Initially — Before you even think about getting on the roof, do a thorough visual inspection from the ground. Use binoculars if necessary. Look for obvious missing shingles, exposed decking, or any other visible damage. Never climb onto a roof during or immediately after a storm, especially if it's wet, icy, or still windy. Prioritize your safety over a quick fix. If you see any signs of significant structural damage (sagging, large holes), call a professional immediately.
• Ladder Safety — If you decide to proceed, use a sturdy extension ladder placed on firm, level ground. Ensure it extends at least three feet above the eave line and is secured at the top. Have a spotter hold the ladder if possible. Wear appropriate non-slip footwear and work during daylight hours when conditions are dry.

2. Damage Assessment & Debris Removal – Identify all affected areas and clear loose debris.

• Locate All Missing Shingles — Once safely on the roof, carefully identify all areas where shingles are missing or severely damaged (torn, creased, or lifted). Note the type and color of your existing shingles if you plan to get replacements.
• Clear the Area — Gently remove any loose shingle fragments, nails, or other storm debris from the affected section. Be careful not to damage surrounding intact shingles during this process. Use a trowel or flat bar to carefully pry up the edges of adjacent shingles if needed to inspect beneath.

3. Temporary Tarp Installation (If Immediate Rain is Expected) – Protect your home from further water intrusion.

• Measure and Cut Tarp — Measure the exposed area and cut a heavy-duty waterproof tarp (at least 6-mil thick) to extend at least 2-3 feet beyond all edges of the damaged zone. This overlap is crucial for effective water diversion.
• Secure the Tarp — Lay the tarp over the damaged area, making sure it's as flat and taut as possible. Begin at the bottom edge and work your way up, securing it with 2x4s or similar lumber. Wrap the edges of the tarp around the lumber strips and nail through the lumber and tarp into the roof decking, ideally into sturdy rafters if possible. Use roofing cement to seal around the nail heads. Do NOT nail directly through the tarp into the shingle field if you can avoid it, as this creates new holes.
• Drainage — Ensure the tarp directs water off the roof and away from the house, not into gutters or down walls.

4. Prepare the Area for New Shingles – Create a clean, stable base for replacement.

• Remove Old Nails and Debris — Using a pry bar or claw hammer, carefully remove any old nails from the exposed decking. Scrape away any remaining roofing cement or shingle remnants, ensuring the surface is as clean and flat as possible. Be gentle to avoid damaging the underlayment underneath.
• Inspect Underlayment/Decking — Check the exposed underlayment for tears or punctures. If it's damaged, patch it with a piece of compatible self-adhering asphalt membrane or roofing felt, overlapping it by several inches on all sides. Secure with roofing nails or staples. If the plywood decking itself is soft, rotted, or severely delaminated, this repair is beyond the scope of a simple shingle replacement; call a professional to assess the structural integrity.
• Lift Adjacent Shingles — To properly install new shingles, you'll need to carefully lift the bottom edges of the shingles in the course directly above the missing ones. Be gentle to avoid creasing or cracking them. A shingle pry bar or even a flat trowel can help.

5. Install New Shingles – Replace missing shingles, matching existing ones.

• Match Shingles — Use replacement shingles that closely match your existing roof in color, style, and brand if possible. Differences in age and weathering mean a perfect match is unlikely, but a close match will blend better. If you have any spare shingles from the original installation, now is the time to use them.
• Cut Shingles (if needed) — If replacing partial shingles or working around obstructions, cut new shingles to size using a utility knife and a straightedge. Always cut from the back side to preserve the granular surface.
• Slide into Place — Carefully slide the new shingle(s) underneath the bottom edge of the course above, aligning them horizontally and vertically with the existing shingles. Ensure the exposed portion (the
