In Johnston, from busy roads to quieter wooded lots, roofs deal with snow, ice, rain and summer heat. Roof ventilation is an important part of keeping your attic dry and your shingles in good shape.

Good attic ventilation lets cooler air enter low and warmer, moist air escape high. That movement helps:

• Reduce attic heat buildup on hot days.
• Limit condensation that can lead to mold, mildew and wood rot.
• Help control ice dams along the eaves in winter.
• Extend the life of shingles and roof decking.

Common warning signs in Johnston homes include a very hot attic in warm weather, musty odors upstairs, rusty nails in the attic and frost or dark staining under the roof deck during the winter.

A typical system includes:

• Intake vents at the soffits to allow cool outside air into the attic.
• Exhaust vents at the ridge or high on the roof to let hot, moist air out.

When we replace a roof in Johnston, we do not just swap shingles. We check soffit openings, ridge vents and any older vents to be sure the attic can actually breathe and support your new roof.

To see how ventilation fits into the full system, take a look at our Residential Roofing page. If you are planning a full roof replacement, our Instant Roof Estimate tool can give you a close cost range for your Johnston home.
