Have your chimney flashing (the seal between the chimney and the roof) inspected and maintained. Flashing prevents rain water and snow melt from entering your home and causing costly damage to your walls and ceilings.
Termites and other pest can cause expensive damage. Here’s what to look for: sawdust-like accumulations of frass indicate the presence of termites. An exterminator can spray or set traps to eliminate the infestation. A clean hole without cobwebs or leaves indicates an access hole for rodents. An exterminator can set a trap for them, too.
