How to ventilate the attic in a home

Attic ventilation is done to cool the insulated ceiling space in a home. The vents allow air to enter into the space between the ceiling and the roof. This space sometimes has damp air or due to hot weather it gets quite stuffy. The insulation applied in the ceiling space in the attic sometimes produces vapor. The cool air in the from the vents assists in removing this mist air. The vents are done on two opposite walls in the roof space for cross ventilation to take place.

Attic ventilation is done on the gable walls opposite each other. This are the triangular walls in the home after the ring beam. The size of the vent space is about two feet by two and a half feet wide. They are usually timber louvers fixed in a frame work. They should allow air passage into the roof space without letting in rain water. The louvers should also be provided with a shutter to close. This is in particular weather with very low temperatures like winter or severe storms.

The attic ventilation commences by marking the position on the wall. This is done for old houses while for a new wall the space is marked an left open. The wall is cut at two courses from the gable top. The wall is then plastered to the required finish after roofing. The frame work is done of two feet wide by two and a half high. This frame w work is done with treated and dry timber. This is because of the position at which it is fixed. It should take harsh weather conditions without getting damaged.

The frame work is then positioned at two inches into the wall. The timber members are four by two inches thick. Fixing is by screwing into the wall. The upright members have slots angled at forty five degrees. The louvers are timber pieces of two by a three quarter inch thick. They are then inserted and glued into the angled slots. Painting is done with oil paint. A gauze wire is then nailed on the inside of the wall to prevent birds and pests from coming into the attic room.

How To Make Your Roof Survive The Winter

Winter months take a toll on your roof. If your roof is not in shipshape condition, it can put you to a lot of time waste and expense on account of significant damage that needs to be urgently remedied. It is therefore, advisable that you take steps necessary to ‘tone up’ your roof condition while the weather is good for making roof repairs before the arrival of winter. It is rightly said, ‘A stitch in time saves nine’.

A leaking roof is one of the biggest problems. The most common sources of leaks can be cracks and damage to the flashing around vents and chimneys. Other potential reasons can be missing and worn out shingles or condensation as a result of inadequate ventilation in the attic.

A pointer that your roof system needs a leak repair is the presence of ceiling spots. Visual inspection from a vantagepoint allowing you to externally check your roof can reveal missing or cracked damaged shingles. These should be replaced at once to avoid structural damage to the roof deck and the home interior. If a crack in the flashing is diagnosed, the flashing needs to be replaced or can be repaired if the damage is small.

If shingles appear curled or buckled, the problem is probably on account of aged shingles or damage to the felt underlayment under the shingles. Underlayment is a weather protection layer in the roof and its damage can lead to accumulation of moisture; the ultimate enemy of all roofing systems. Underlayment is now available in self-adhering rolls that are applied directly on the roof deck or can be laid as a layer on top of the existing underlayment. Damaged shingles should be replaced and underlayment though costly must be replaced, must be changed, if required. If shingles appear blistered, it is usually because they were applied on a wet deck or due to inadequate roofing ventilation. Proper roof ventilation allows natural flow of hot air upward out of the attic and keeps the attic cool and dry.

In winter, the prime cause for concern is the moisture build up in the attic. Despite the vapor barrier in the floor of the attic, unwanted moisture seeps into the attic with the air leaking through ceiling light fixtures, access panels, fold down attic stairways, bathroom exhaust fans etc. The cold outside of the roof makes moisture condense on the framing members and inside the roof deck and supports growth of mold, mildew and rot. This seriously affects roof deck strength and longevity. Inadequate attic ventilation can also make ice dams form on the shingles. Water accumulation behind icedams can seep into the attic/house through the shingles. It is therefore absolutely essential to ensure proper attic ventilation.

If there is inadequate attic ventilation, you may get a ridge vent (if your roofing system does not have one) installed to improve ventilation. Alternatively, a gable vent in the sidewall of the attic can be installed depending on the construction of your roofing system.

Another solution is to have a powered ventilator installed. Improved ventilation will prevent moisture condensation that can severely damage the roof.

If you face roofing problems it is best to secure the services of a qualified roofing contractor for fixing things up. Roofing work is expensive but it will be worth the expenditure in the long run, and to make sure your roof survive the winter.
