Missing, torn, unsealed, and curled roofing shingles are common warning signs that you should address immediately.
Often, missing shingles may lead to significant damage hidden underneath, which not only compromises the roofing system, but could cause moisture to get into the interior.
If water flows down a wall, or pours from around a ceiling fixture, you can detect the infiltration right away. Unfortunately, leaks caused by missing shingles may not be obvious or go unnoticed in obscure locations such as the attic.
Any knowledgeable roofing contractor can determine the extent of damage from missing shingles, and make recommendations for roof repairs. If you ignore the warning sign (s) for too long, it can result in significant and costly damage.
