I also went through the same thing now, and my roofer told me that base on the number of the total squares of my house roof, the extra cost is around $2200.00 (Note: extra cost). So if the regular shingles material cost is 2000 then the total cost for using the reflective granules shingles would be 2000 + 2200 =~ 4200 total.

I am a custom home builder in California and have found that the cool roof shingles are much more expensive.  I have installed 3 cool roofs in the last year and most recenly paid more than $40/square extra for the gaf elk cool roof

All aspects of residential Roofing. This includes shingles and flat (low slope) roofs. I have knowledge in the installation as well as the design of roofs from an engineering standpoint.


I have been doing roofing for 40 years. This was my father's business and I took it over in 1980.

I have written responses to artcles that I felt needed a response to and those responses have been published in roofing trade magazines.
