Eave Slate - A moulded concrete tile which is mechanically fastened to the eaves of the roof. Eave slate serve two purposes (1) they prevent water run-off from getting under the eaves (2) they are the first line of defence in reducing the occurrence of up-lift in high wind conditions.

Roof Slate (Tile) - These are 18”x12”x1” tile, which overlap each other by half (9”) all the way up to the ridge of the roof.

When looking at pictures of Bermuda Roofs one may notice holes located a few rows below the ridge. These holes are vents (ventilation slots) and were first built into the Bermuda Roof around the year 1850 due to the wide-spread introduction of ceilings which cut down on the circulation around the roof framing, which is bad for timber. They also allow for ventilation and pressure equalisation in high winds, a fact that is sometimes overlooked.

Clips or Screws - These alternative fasteners have proven to greatly enhance the uplift threshold of our Traditional Bermuda Roof.

Mortar Additive - Unlike in Bermuda were sand is made from crushed limestone, the sand in the Bahamas and some Caribbean countries is dredged from the ocean and this sand has “no nutrients”, which causes the mortar to dry to quickly resulting in more mortar joint cracks and reduced bonding of the slate. The additive adds the “nutrients” back and slows the mortar drying process.

Elastomeric Paint - We have chosen to use a very high quality elastomeric paint that is approved for potable water. This high quality paint also reduces the maintenance requirements of the roof.

EPS Bermuda Profile Roof Tiles - Contrary to what our competitors use, our EPS tiles are NOT 4’x8’x4” because it has been proven time and time again that large tiles result in cracking in the roof. This cracking is as a result of the Co-efficient of Linear Expansion (CLE), our tile are small enough to ensure that the amount of joints are sufficient to take up the CLE resulting in very few, if any, instances of cracking. We pride ourselves on long-term performance. From an aesthetic perspective, the profile of our EPS tiles is traditional Bermuda, so that to the untrained eye there is no difference between our EPS roof and our Traditional Bermuda Roof.

Cement Board - Plywood has traditionally been used as a roof substrate in the Bahamas and Caribbean and most would be aware that after time plywood begins to delaminate, shortening the life of the roof. To avoid this problem, we recommend the use of a cement board as an alternative substrate. While the use of cement board may increase upfront costs, it will pay for itself in the long-term because it will not delaminate and it is fire and insect resistant.

Adhesive - Our EPS roof has its “roots” in Bermuda as a similar system was first created in Bermuda in 1968. Adhering the tiles directly to the substrate provides a superior uplift threshold. Additionally, this method allows the EPS tiles to move with, not against, the flexing of the roof and creates a monolithic structure.

EFIS Screws - Where the typical roof structure in the Bahamas and Caribbean of plywood and Ice & Watershield underlayment we mechanically fasten our EPS tiles to the roof using EFIS screws.

Fiberbond - This is a Kaidisen proprietary cementious product that creates a hard shell over the EPS tiles yet it is pliable enough to absorb the expansion and contraction of the EPS tiles to help to reduce/eliminate cracks in the roof. On many occasions we use Fiberbond to coat ridges, valleys and hips of our Traditional Bermuda Roofs to prevent cracking at these locations.
