How to check the thermal insulation of the roof?

Satunnainen

Checking the thermal insulation of the roof is an important measure that can help save energy and improve home comfort. A well-insulated roof prevents heat from escaping in the winter and keeps the home cooler in the summer. In this article, we go through how you can check the thermal insulation of the roof and what things should be taken into account.

Why is thermal insulation of the roof important?

The thermal insulation of the roof is one of the most important factors in terms of home energy efficiency. A well-insulated roof:

  • Reduces heating costs in winter
  • Improves home comfort
  • Reduces the carbon footprint
  • Prevents the formation of moisture and mold

Steps for checking the thermal insulation of the roof

The following is a step-by-step guide to checking the thermal insulation of the roof:

  1. Visual inspection: Start by visually inspecting the attic or roof space. Look for insulation defects, damage or signs of moisture. If the insulation looks flattened or uneven, it may be a sign that the insulation is no longer effective.
  2. Measurement: Measure the thickness of the insulation. The recommended insulation thickness varies depending on the climate, but in Finland, insulation with a thickness of at least 30-50 cm is generally recommended. You can use a tape measure or special tools to measure the thickness.
  3. Using a thermal camera: A thermal camera is an excellent tool that you can use to detect heat leaks. The thermal camera shows the temperature fluctuations and helps to identify the places where the insulation is insufficient. You can rent a thermal camera or hire a professional to do the check.
  4. Checking for air leaks: Check for air leaks in the roof or attic. Air leaks can significantly reduce the efficiency of the insulation. You can use a cigarette or a candle to detect air leaks; the movement of the flame reveals the air flow.
  5. Moisture check: Moisture can reduce the effectiveness of the insulation material and cause mold problems. Use a hygrometer to check the moisture content of the insulation. If you notice moisture, find the source and fix the problem.

When to call a professional?

Although many checks can be done yourself, there are situations where professional help is necessary:

  • If you notice significant damage or moisture
  • If you are not sure about the condition or thickness of the insulation
  • If you want to do a thorough thermal imaging

A professional can give more detailed recommendations and help make the necessary repairs.
