If your shingles are lifted by wind but not completely missing, you need to act quickly to prevent them from tearing off and to prevent water intrusion. First, document the damage with photos from the ground for insurance purposes, and do not climb on the roof during high winds or wet conditions. If the shingles are still attached but the sealant bond is broken, you can often reseal them as a temporary or even permanent fix if the mat is not creased. On a calm, warm day when shingles are pliable, gently lift the lifted shingle and apply a quarter-sized dab of roofing cement or asphalt sealant under each corner and in the middle above the sealant strip line. Press the shingle down firmly and apply light pressure for 30 seconds. Place a small weight like a brick on it for a few hours if accessible. If the shingle is creased, cracked, or the mat is broken, resealing will not work long-term because its wind resistance is compromised and it should be replaced. For multiple lifted shingles, call a professional roofer as the damage may be extensive and you may have an insurance claim for wind damage. Avoid using silicone or excessive tar that can prevent proper future sealing. If many shingles are lifted across the roof, your roof may have experienced sealant failure due to age and may need more comprehensive repair.
