Got Attic Mold? Lets Talk Energy Conservation!

Got Attic Mold? Lets Talk Energy Conservation!

It happens to countless homeowners around the end of the year – you make the annual visit to your attic to collect the holiday decorations and what do you find? Spots and blotches covering the bottom of the roof sheathing. Worse yet – it turns out to be attic mold!

What does energy conservation have to do with mold in the attic? Well if you take a step back and consider how the house behaves as system, they are often directly related.

Building science experts have long been using the “house as a system” approach to diagnose the cause and origin of building defects.

For example, ice dams. These are often caused by warm air seeping into the attic which causes the snow and ice on the roof to melt. The water drains to the edge of the roof (which is colder than the rest of the roof because it is an overhang and not warmed by the attic), freezes and creates an ice dam. As this process is repeated daily, the ice dam grows larger. Eventually water is forced under a shingle where it can seep into the house.

Understanding how the house behaves as a system and the various causes and effects is necessary to diagnose most building related problems.

But how about that attic mold? How did it get there?

Mold requires chronic moisture to form and to thrive, so source(s) of moisture must be present. Possibly the moisture came from outdoors. The roof is newer and a quick check of the roof shows no obvious damage or leaks.

Possibly the moisture came from indoors. During the heating season, the interior of the house frequently has high moisture levels, especially bathrooms and kitchens. A quick check shows that all bathroom fans, kitchen vents, etc. are properly ducted completely outdoors and not into the attic. The amount of insulation looks good and the attic is well ventilated.

Don’t give up – you are almost there! Remember the house as a system? You know that warm, moist air is in the house, but how is it getting into the attic?

By air leaks! Air leaks are the leading source of energy loss in most houses, and a frequent source of chronic moisture that can cause attic mold. Most homeowners are well aware of air leaks around windows and doors (especially old ones), but many overlook the numerous gaps leading directly into the attic!

Have a look around the attic and you may find large gaps around recessed lights and fans, holes where wires or pipes are installed, even large gaps around the chimney. And don’t overlook the whole house fan and especially the folding attic stair – a big, uninsulated hole in your ceiling that is often overlooked!

These gaps can add up to a large hole that allows warm, moist air from the house to flow right into the cold attic. The warm moist air condenses on the cold roof sheathing, creating chronically damp conditions that can lead to attic mold growth. And the energy loss – it can be like leaving a window open all winter long!

Seal these air leaks and you stop a significant moisture source. And just think of all the energy you can save and the cold drafts you can stop!

What to Do About Water Damage in Your Attic

Wintry climates
If you live somewhere that snows in the winter, ice dams will be your biggest concern. The best way to prevent ice dams from forming is to keep the attic at least five degrees warmer than outside. If there is snow on the roof, do not attempt to remove it; you could damage your roof. Instead, check all exterior walls for staining. If you find any, act quickly to avoid further damage. Call a qualified professional and get help. If you do get ice dams, do not attempt to remove them, you could cause more damage to your roof. Besides calling a professional, you can temporarily remedy the problem by cutting grooves into the ice to allow the pooled water to drain. Just be sure to not cut all the way down to the shingles.

Ventilation
Bad ventilation can keep the attic humid causing condensation to run ramped, but this is not only place to worry about humidity. Research has indicated that humidity in the living space is a major cause of condensation in the attic. To help prevent this, be sure that the attic is sealed off from the rest of the house. If discoloration, condensation or mold is found on or around your vents, immediately trace it to the source, and repair the damage right away. It is also important to check outside for debris that may be building up on the vents.

Insulation
Insulation is going to be like a canary in a coalmine when it comes to early prevention of water damage. The most important time to check your insulation is after it has rained. Be sure to give it a good feel, even if it looks dry, because the slightest amount of moisture means you probably don’t have enough ventilation. Keeping your insulation in good condition is not only important for preventing water damage, but it will also keep your heating bill from running up, up and away.

Floor, ceiling and crawl spaces
These areas take a bit more time to check for signs of moisture, but are just as important as the rest of the attic. Be sure to use a flashlight and check thoroughly for discoloration and staining, as these will be harder to spot than rot and warping. Also, be sure to look with your hands as well as your eyes, especially around nails as they are metal and condensation will settle on them first.

Recessed lighting
Checking in and around recessed lights is one the most reliable way of detecting possible water damage. If you find corrosion or rust in the lights, be careful, it could be an electrical hazard. If you know how, turn off your power and repair the light, other wise call an electrician. Also be sure to trace the damage to its source and make all necessary repairs.

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.
