Many times home owners and business owners will replace an entire roof because of isolated leaking. If you have a chimney, skylight or roof penetration that is leaking often these can be repaired at a significant savings over replacing the entire roof. We understand that contractors who are not successful trouble shooting leaks have a tendency to draw the conclusion that a leak is an indication that the roof should be replaced as a whole. We do not subscribe to this misconception. Shingles that have become brittle with age would be the only issue that would preclude repairs.
