Ways to Cool Your Roof

The temperature at the top of a typical rooftop can be 50 degrees Fahrenheit (or 10 degrees Celsius) warmer than that in the surrounding area on a bright day. It's not surprising to find that the temperatures in large urban areas, with block after block of black roofs that absorb heat, can be as high as 6-8 degrees higher than those in the surrounding areas.

6. Spread the modified bitumen onto the ground.

The roof slope will determine the requirements for a cool roof.

A cool roof can install on any type of roof. Additionally, existing roofs can be made cool with the addition or modification of suitable coatings.

Find out the slope of your roof before you decide which roofing materials will be best suited for your house or structure.

A modified bitumen rooftop is the most common type of cool roof for a low-sloped or flat roof. Modified bitumen roofing, made of rubberized or plasticized asphalt strips, is a membrane that is held together using rolled reinforcing fabric. Hot asphalt or cool adhesive are used to adhere it to the roof deck.

5. Choose a membrane having only one ply.

A single-ply membrane is another type of cool roofing material suitable for low-sloped roofs. Single-ply roof membranes are prefabricated plastic or vinyl sheets that have solar reflective coatings. The sheets are laid on the roof deck using chemical adhesives, mechanical fasteners, ballast, gravel, pavers, etc. Cool roof qualities can be built into single-ply membranes which do not require any additional coatings.

4. Strengthen it

Built-up roofing (BUR), also known as traditional tar & gravel roofs, is what you mean by the term. Because it's easy to install and is quick to repair, it's one of the most popular roofing options for flat and low-sloped roofs. A protective layer of either gravel, mineral, granules, or some other form of rock is placed over an asphalt sheet or bitumen. This protective layer is then followed by a protective level of gravel and mineral granules.

3. Roof Cooling Costs

A cool built-up roofing system can cost anywhere from $1.20 - $2.15 per sq. foot. This is roughly the same as a traditional build-up roofing, although the third option -- applying coatings over an existing surface -- is slightly more expensive at $.80 - $1.50/square foot.

2. You can add a layer of cool

In good condition, low-sloped roofs are the best candidates to apply cool roof coatings. [source : Environmental Protection Agency]. Cementitious coats with concrete or ceramic pieces and elastomeric coated with additional polymers that make them less fragile and more sticky to building surfaces are divided into two distinct groups.

Both cementitious, as well as elastomeric coatings, can increase solar reflectivity. Elastomeric roof coatings create a waterproof barrier. However, cementitious roofing materials must be covered with cementitious coats [source: EPA].

1. Find the right shingle

For steep-sloped roofs that are not suitable for standard fibreglass asphalt, cool asphalt can be substituted.

Cool asphalt shingles are made from standard fibreglass asphalt shingles. They have specially coated reflecting granules that help to reflect sunlight better onto steep-sloped roofs. For shingles made of wood or polymer, you can apply coatings that increase their solar reflectivity.
