In Bristol, with homes near the harbor, the parade route and quiet side streets, roofs deal with moisture from the bay plus real New England winters. Roof ventilation is a big part of keeping your attic dry and your shingles in good shape.

Good ventilation lets your attic breathe. When air can move in at the soffits and out near the ridge, it helps:

• Reduce attic heat in the summer so the living space stays more comfortable.
• Limit moisture and condensation that can lead to mold or wood damage.
• Cut down on ice dams by keeping the roof deck closer to the outside temperature.
• Support the full life of your shingles and roof structure.

Signs of poor ventilation in Bristol homes include an attic that feels extremely hot on warm days, musty smells upstairs, rusty fasteners, or frost and staining on the underside of the roof deck during cold weather.

A balanced system usually has:

• Intake vents along the soffits that let cooler air in down low.
• Exhaust vents at the ridge or high on the roof that let hot, moist air escape.

Whenever we replace a roof in Bristol, we check the existing ventilation and correct issues while the roof is open. We look at soffit openings, ridge vents, baffles and any older box or gable vents that may no longer be doing their job.
