Condensation is a common issue in commercial buildings, often affecting windows, skylights, roof hatches, and smoke vents. At SkyRight, based in Sandpoint, ID, we prioritize effective solutions for managing indoor moisture levels and preventing structural damage.This guide explores the causes of condensation, its impact, and actionable methods to mitigate it in commercial spaces.
Understanding Condensation
Condensation occurs when warm, moist air meets a cooler surface, such as roof hatches or smoke vents. The temperature difference causes water vapor in the air to condense into liquid.
Key Causes:
- Excess Indoor Moisture: Generated by human activity (breathing, cleaning, cooking) or equipment like propane forklifts.
- Temperature Differentials: During colder months, warmer indoor air holds more moisture, which condenses upon contact with cooler exterior surfaces.
Why Condensation Peaks in Winter
In winter, the contrast between indoor and outdoor temperatures amplifies condensation issues. The colder the surface, the more likely it is for water vapor to condense.
For instance, roof hatches and skylights can be especially vulnerable due to their exposure to external cold and internal warm air.
Strategies to Prevent Condensation
- Control Indoor Humidity Levels
- Use dehumidifiers during the colder months.
- Reduce sources of indoor humidity by addressing leaks or limiting water usage.
- Improve Ventilation
- Allow dry, fresh outdoor air to replace moist indoor air.
- Consult HVAC specialists to optimize airflow within the building.
- Circulate Air Effectively
- Use ceiling fans to prevent warm air from accumulating at the ceiling.
- Enhance air movement near roof hatches and skylights to reduce “spot condensation.”
- Install Thermally Broken Roof Hatches
- Consider advanced solutions like thermally enhanced hatches or vents to minimize temperature discrepancies.

FAQs
Q1: What is the ideal indoor humidity level to prevent condensation?
Aim for 20-40% humidity in winter, depending on external temperatures.
Q2: Can condensation damage my roof?
Yes, prolonged condensation can weaken structural elements and promote mold growth.
Q3: How do thermally broken roof hatches work?
They minimize temperature transfer between indoor and outdoor environments, reducing the likelihood of condensation.
Q4: Is condensation a sign of a ventilation issue?
Often, yes. Poor ventilation traps moist air, increasing condensation risks.
Q5: How often should I check for condensation issues?
Regular inspections during seasonal transitions, especially in winter, help identify and address problems early.If you want to read a blog about flashing a roof hatch on built-up roofs with a hot application guide, click here.
