Do You Feel Like a Cat On A Hot Tin Roof With A Metal Roof System?
Today Stone Coated Metal Roofs are fast becoming the new roof investment of choice over traditional roofs. Metal roofs are not only sleek and modern looking but they add a distinguishing style and a solid long-term permanent investment not only in their roof but their home.
HOWEVER, do metal roofs make your house hotter is the question for today? It may seem like a fair roof question based on what we know and understand topically about metal and how metal conducts heat. But, the real answer is not so easy or straightforward.
Let me first assure you - metal roofs do not make a home hotter more than any other type of traditional roofing material available today or yesterday. Metal roofs have a low thermal mass and reflect light and heat rather than absorb it, like traditional asphalt shingles. What this means to you is that rather than making your home hotter during the seasonal spring and summer months, metal roofing actually helps keep your home cooler and has been documented to increase your overall home’s energy efficiency which can result in a hug savings.
However, the degree to which your metal roof retains heat depends on several factors and is why a stone coated metal roof is the ultimate permanent roof system solution. How much your metal roof system absorbs or reflects heat depends on these areas:
- Type of Roofing Finish and Coating - Some can reflect over 70% of the sun’s solar energy
- Roof Color Choice - Dark roofing colors will absorb more heat than light roof colors
- Roof Sun Exposure and Amount of Roof Mass - The more roof mass receives more direct sunlight and takes longer to cool
- Efficient Roof Ventilation - A good ventilation system combines ridge vents and soffits to allows air to circulate out of the attic space
