Fixing leaky roofs doesn't always require replacement. Most of the time, all that is needed is to fix the leaky roof flashing. With just a simple repair, you can stop the drips without spending lots of cash. Most roof leaks happen when chimneys, vent pipes or other openings have loose or deteriorated flashing. Fortunately, flashing repairs are usually easy and inexpensive. Always attempt to seal loose flashing with roof cement before committing to larger and more expensive roof repairs.
