1. Inspect flashing in the valleys of the roof, around the chimney and enclosing plumbing vents to ensure a tight seal against water. Use roof tar to seal any edges that have lifted up. 2. Visit your attic and inspect the under side of your roof system for water stains, as well as matted or mildewed insulation. If you have a cathedral ceiling, look for water stains on the drywall or on the tongue-and-groove paneling. 3. If you have exposed timbers on the underside of your eaves that extend flush with the overhand or protrude past it, the ends of these logs are susceptible to rot. Treat with Shell-Guard then sand and seal with Log End Seal. 4. Did you see ice buildup (ice dams) on your roof last winter? Prevent warm-air build-up in your attic during winter months by increasing the amount of insulation (less heat will enter your attic). Or improve ventilation so warm air escapes quickly.
