If you discover a leak in your roof it is very important that you call a roofing contractor right away.  Not having a roofing problem fixed right away will cost you more money in the long run because your home is very likely to have water damage to your woodwork (especially hard wood floors), insulation, drywall, windows and doors.  The high moisture content in the attic and other areas the water runs to will probably begin to grow mold and mildew.  Both of which can have adverse health consequences, especially for individuals with breathing disorders like asthma.  The elderly and young children are also at higher risk for having health issues related to bacteria growth in mold and mildew.

When it comes to rook leaks homeowners need to understand that water leaks are very tricky.  Water often gets under the roofing material and then runs the next layer once again looking for a weak spot.  Water does not always travel straight down or straight through a roof.   Water can get in and then run down or along the roof trusses.  It can seep down the sidewalls or puddle up on the moisture barrier until it finds a breach in the barrier.
