If you can’t see any telltale flow marks, and since the stain is fairly small, look at the underside of the roof for ‘shiners.’ A shiner is a nail that missed the framing member, in this case when the carpenter nailed the roof sheathing to the rafters. Moisture that escapes into the cold attic from the rooms below often condenses on cold nails. Sometimes you can spot this if you climb up into your attic on a cold night. The nails will look white because they’re frosted. When the attic heats up a bit during the day, the frost melts and drips, then the nails frost up at night again and so on. The solution is to simply clip the nail with a side-cutting pliers.
An estimate was that in 2003, the market for home-maintenance and repair spending was up 14% from 2001 to 2003. Another estimate was that the market in the United States was $126 billion and was increasing by about 4% annually. American homes are aging; one estimate was that in 2007, more than half of all homes are older than 25 years. And, as populations worldwide tend to become older, on average, and since increasingly elderly people will be less inclined and able to maintain their homes, it is likely that demand for handyman services will grow.[original research?]
There's no national standard or regulation for handymen. Licensing and regulation vary by state. New Jersey, for example, requires handymen who work for a profit to register with the state and carry insurance. California requires handymen to carry a license from the State Contractors License Board to work on any project that exceeds $500 in labor and material costs.
