This is a cool article I found on This Old House that dives a handy checklist for doing a yearly inspection of your own house. This for anywhere but will be especially useful for inspecting your house in Los Angeles. It is really hot this time of year so be very careful if you plan to go up on your roof or crawl under your house looking for any of those hazards or faults in your house.
Here is a snipit. Find the rest here.
Use this detailed checklist as a guide as you look around for leaks, cracks, breaks, wear, and every other conceivable problem that can develop over the year. Then make a repair list to keep up on maintenance in the coming months.
