Frost In Attics- Know Its Causes And How To Fix It.

What is Frost?

Frost is a common occurrence in houses during winter seasons. As the mercury drops, the warm air present inside the house makes its way up and tries to escape through the bypasses. On reaching the bypasses, due to a dip in temperature, the moisture condenses on the roof boards and rafters and as a result, the frost gets formed.

As the outside temperature rises in summers, the frost thaws, water gets collected, and can leak into your house. If the water stays in the attic it further leads to a bigger problem, the mold.
Poor drainage is also a major cause of excess moisture. Proper drainage and construction details like flat ledges, badly designed drip edges, and bad flashing add to the problem. The absence of regular maintenance also leads to water seeping through the siding, windows, doors, and even light fixtures.

Adding more attic ventilation might seem to be the obvious solution to this problem, but it’s not. Adding roof vents will only allow more air to escape from the house and it will result in more warm and moist air entering the house.

How to Fix Frost And Moisture Problems

Finding a solution to frost and moisture is a little complicated. The problems are due to a lot of causes that demand a combination of solutions for a long-lasting result. We need to strike a balance between adequate ventilation and adequate moisture levels to create a healthy and comfortable living scenario.

Symptoms Of Excess Moisture And Frost

Excess Moisture And Frost

1. Bad Odor- Musty smells signal towards mold infestation, mildew growth, and in worst cases, rot. Also, odors from everyday household activities seem to linger too long in houses having high moisture.
2. Frost and ice on cold surfaces- Frost or ice on cold surfaces like windows and attic ceilings is a sign of trouble. A malfunctioning heating plant or a flame-fired appliance also causes excess moisture and gases to enter the house.
If you are experiencing frequent headaches, drowsiness, or other unexplainable prolonged ill-health, take a closer look at the moisture level and state of insulation in the attic.
3. Discolored and stained walls- These are signs of frost and moisture damage. They appear as black or dark streaks or discolored lines. The area might not be even necessarily wet.
4. Worn-out insulation- Old and worn-out insulation leads to higher moisture levels in the house which leads to frost in winters.

Solutions –

1. Temperature difference due to inadequate insulation- As warm and moist air hits the colder surfaces, it results in condensation and frost damage, which further leads to mold or mildew. Rooms away from the heating appliances like attics often face frost problems. Uninsulated ceilings, walls, and windows are the most commonly affected areas.
2. Frost on the underside of the roof sheathing and attic cover protection are other problem areas.
3. Eliminating attic bypasses is the main strategy to avoid moisture problems in attics.
