Pros and Cons of Reflective Metal Roofing Paint
There are many reflective metal roofing paints available on the market for do-it-yourself projects. Before making the investment in these paints and the time commitment to apply them to a roof, you need to ask yourself a few questions. Review the pros and cons of using reflective metal roofing paint and you will be able to determine if this paint is right for your needs and the desired outcome you have for your do-it-yourself project.
Step 1 - Heat Reduction
If you are looking to reduce the heat in the building or structure which has the metal roofing you are looking to paint then this may be the paint for you and your needs. This is because reflective roof paint can deflect up to 85% of the heat hitting the roof. This means it can reduce the temperature inside the structure as much as 50 degrees in some conditions. If you are not in need of heat reduction this paint may be a wasted expense. If you are unsure then measure the temperature inside the structure on a hot day with a weather thermometer to determine of the contents of your structure would benefit from a temperature lower than what you register.
Step 2 - The Environment
If you are looking for an environmentally-friendly paint and you are not in need of reducing heat in the structure then this may not be the paint for your metal roof due to its contents. Roofing paints typically contain high levels of VOCs, which can affect air quality. If you decide to paint the roof, reduce the amount of air conditioning used inside the building.
Step 3 - Chipping and Peeling
If you are not in need of heat reduction you may want to look at another paint for your metal roof since this paint is known to chip and peel faster than traditional paints.
