After any kind of storm, homeowners should always take a quick look at their roof to ensure that the shingles remain intact and undamaged. If damage is discovered, homeowners should know how to repair roof shingles that have blown off. It is a relatively easy process.
If you notice shingles are missing following a storm, don’t wait.
They need to be replaced, or the roof area covered, to prevent water damage to the supporting roof structure and leaks inside.

How to Repair Roof Shingles That Have Blown Off
The easiest way to repair roof shingles that have blown off is to individually replace them or replace a series of them.
The damaged shingles can be removed and new ones can be put into their place. However, these patches may be noticeable, as weather conditions can cause the older shingles to fade in color.
Your tool kit:
The tools you’ll need to gather to repair roof shingles that have blown off include:
- Pry bar or nail puller, hammer, utility knife
- Galvanized roofing nails
- Matching shingles (one bundle is sufficient for small repairs)
Steps to Replacing a Shingle
Using the pry bar, remove the damaged shingle and old nails that may be still attached to the roof. If the shingle is missing altogether, remove any debris or remaining nails. Generally, there are four nails: two holding the missing shingle and two holding the one above it that penetrate the shingle below it. Remove those temporarily as you slide the new shingle into place. Do not place a new shingle overtop old nails; this can puncture the new shingle.
Slide a new shingle under the one above it, taking care not to damage or displace the existing shingles. You may need to remove the shingle nails of the shingle above it in order to create a secure attachment. Replace the existing shingle and nail into place, and replace the nails in the single above it.

How are Roof Shingles Blown Off in the First Place?
There are two methods by which shingles are attached to a roof: roofing nails or adhesive strips.
Generally roofing nails have short shanks, sharp points, and wide, flat heads that enable them to penetrate the shingle without tearing it.
Some shingles are made with adhesive strips attached to the bottom which, when attached, creates a strong, waterproof seal to the shingle beneath it.
Reasons a roof shingle may be blown off include:
Nails may be placed too high on the shingle instead of through the nailing strip, allowing the shingle to tear under adverse conditions.
If the underlying roof structure is damaged or decaying, the shingles cannot attach securely and can allow moisture or wind to gather underneath them. With decay, the shingle nails can pop out and loosen the shingle.
Cure time not sufficient.
When adhesive seals are used, they need time to cure in order to operate at their maximum efficiency: about 4-6 weeks, depending on the rain and sun conditions. A newly-placed shingle may not have had sufficient time to set.
A typical roof normally lasts between ten and 15 years. As shingles age and endure years of exposure to the elements, they become weaker in material and seals.
