Examine roof shingles to see if any were lost or damaged during winter. If your home has an older roof covering, you may want to start a budget for replacement. The summer sun can really damage roof shingles. Shingles that are cracked, buckled or loose or are missing granules need to be replaced. Flashing around plumbing vents, skylights and chimneys need to be checked and repaired by a qualified roofer.
