You can usually make a new or existing roof cool by selecting the appropriate surface.
How expensive is a cool roof.
It tends to be more expensive than tpo but is well known for long term performance and is naturally fire retardant.
Once a product is rated the results are published on their online rated products directory which is a great.
The cool roof rating council crrc is an independent non profit organization that maintains a third party rating program which rates and publishes a roof product s radiative properties solar reflectance and thermal emittance.
Like all roofing projects however costs can vary depending on multiple factors.
Not all single ply membranes are cool roof products but the average cost of cool roof single ply membrane is only slightly higher than the cost of traditional single ply membrane about 1 50 3 per square foot for cool roof materials versus around 1 to 2 per square foot for standard single ply products source.
Going about installing a cool roof is a matter of timing.
There are many types of roof systems available but the surface exposed to the sun is the one that determines if a roof is cool or not.
Types of cool roofs.
Project size project location climate and ease of roof access.
Solar reflective shingles range between 2 and 3 per square foot depending on manufacturer and vendor.
Generally speaking the cost of installing cool roofing during construction is comparable to traditional roofing as this energy saving calculator demonstrates so small business owners may save on energy costs in long run by installing a cool roof.
They have higher solar reflectance ratings than darker materials but much lower ratings than a white roof ranging between 0 25 and 0 30.
These typically come in mid range colors such as medium browns and grays.
Generally speaking cool roof coatings for lower slope roofs cost around 0 75 to 1 50 per square foot 1 50 to 3 00 per square foot if a single ply cool roof membrane is used.
Cool roofing is known to be very affordable overall with energy savings ranging from 7 15 of total cooling costs.
Combined with the fact that sunlight is directly reflected back at the sun cool roofs can positively impact the environment with lower co2 emissions.
Tpo thermoplastic polyolefin is a blend of polymers that can contain flame retardants or uv absorbers.
If the roof is retrofitted ahead of schedule in order to install a cool roof there will be some incremental cost.
Cool roofs can contribute to lower home energy costs by keeping your roof cooler throughout the year.
