Bermuda Roofs. That is what is shown in the photo below and you may have seen them either in photos or if you were lucky enough to visit Bermuda.

In Bermuda and most of the tropics there is a price that has to be paid in the form of potential hurricanes and lack of fresh water and these roofs were developed over hundreds of years to deal with both issues.

As a note – by law, every home must collect at least 80% of the water that lands on it. Water is a precious commodity.

Below is how a traditional Bermuda roof is built and originally they were made from limestone and then coated with a layer of cement and sealed with a non toxic whitewash. The white roof reflects the sun’s heat and the water brought down to the cistern needs to be as clean as possible for the home’s use.

Now to collect the rain water a integral gutter is made at the bottom of the roof edge which then sends all the collected water to a cistern. Once there, a pump is used to deliver the water throughout the home.

There are also other methods used for a gutter collection system such as the ones shown below.

This one shows a gutter that is built into the wall using a 4″ PVC pipe that connects to the cistern below.

In this photo a ridge is made that guides the rain water to a gutter and down spout.

Today there are a few different materials and methods that can be used for constructing a Bermuda roof and it is no longer limited to limestone. Cement tiles and EPS are now used as well as covering the roof deck with cement board and a layer of Ice and Water Shield. However what hasn’t changed is what a Bermuda Roof does.

It protects the roof from the up lift effects of a hurricane due to the lack of exposed edges and provides much needed fresh water. Tested over time and used in many places.
