  • Cement or nail flashing strips of metal or shingle over joints to make them watertight.
  • Install attic ventilation systems, such as turbine vents, gable or ridge vents, or conventional or solar-powered exhaust fans.
  • Install partially overlapping layers of material over roof insulation surfaces, using chalk lines, gauges on shingling hatchets, or lines on shingles.
