Urban Heat Island Effect

Sorry we haven’t posted for a little while, we’ve been busy getting estimates for electrical, plumbing, HVAC, plastering, and a new roof.
One of the biggest problems with traditional asphalt shingle roofs is they attract a lot of heat. This causes two problems.

1. Contributes to Urban Heat Island Effect (UHI)
2. An increase in annual utility bills

UHI occurs in metropolitan areas and is essentially a micro-climate version of global warming. Beyond the obvious problem of creating an increase in utilities during summer months, UHI causes modifications to wind patterns, an increase in precipitation in and downwind of cities, and even an increase in pollution. While I do not have any statistics on hand, I have seen numerous different statistics and documentation on these matters.
For those of you who believe Fox News over scientists and that global warming is fake, you can’t argue against saving money off your utilities. A lighter more reflective surface will drastically decrease your monthly payments compared to a traditional asphalt shingle roof.
We decided to go with a light-colored standing-seam metal roof. These roofs are economical, durable, and they will look good on our house. From snow to sun exposure to hail, standing-seam metal roofs hold up very well in extreme climates (such as Chicago). Additionally, they have an excellent SRI (solar reflective index). So as a result we will have a good looking roof that is durable, economical, and earth friendly.
