Standing Seam Metal

Primarily manufactured from recycled steel and aluminum, which themselves can be recycled at the end of their life, metal roofing is environmentally friendly by making excellent use of what otherwise would be scrap metal, buried in a junkyard somewhere to pollute the environment for hundreds of years.

And by its very nature, metal is impenetrable to the elements, lasts a very long time, and reflects most of the sunlight off of your roof, rather then heating up and absorbing it into the building. This leaves you with lighter energy bills, and who doesn’t want that?

Concrete Tiles

Concrete roof tile is made of sand, cement, and water. The exact materials vary somewhat with each manufacturer but basically contain Portland cement, blended hydraulic cements and fly ash, sand, and other aggregates. The products from most manufacturers look very similar in size and shapes and colors. There are several manufacturers of concrete tile.

Concrete roof tile has three main appearances based on their profiles:

  • Flat Profile concrete roof tile is flat – no curves when viewed from its butt
  • Low Profile concrete roofing tile has small curves when viewed from its butt that have a rise to width ratio equal to 1:5 or less
  • High Profile concrete tile has larger curves when viewed from its butt that have a rise to width ratio greater than 1:5

Concrete tile is available in several different colors and a couple of textures. The surface texture of the tile can be smooth or rough. Most are color impregnated rather than just slurry coated. Concrete tile is available in standard weight and lightweight tile. It is advisable to stay away from lightweight tile if you can. They are much weaker and hard to walk on without breaking some and are very susceptible to breakage from hail and heavy snow loads compared to standard weight Concrete tile. Lightweight tile costs more than standard weight. In my opinion it would be better money spent to use the extra money it would cost for lightweight tile for consultation fees of a structural engineer and use the standard weight tile.


For many people, choosing a roof is primarily about style, and in this respect, a modern, lightweight Gerard roof offers a myriad of different options to suit architecture of all kinds.

But equally important is peace of mind. You want to feel confident that your roof will continue to protect your home and its precious contents even under the most extreme conditions imaginable.

Gerard roofs have been thoroughly proven over time in over 120 countries around the world.


Copper offers a character and durability that no other metal roof can match. Its appearance can complement any style of building, from the traditional to the modern. Its warmth and beauty make it a preferred material for many architects.

The use of copper is based upon traditional practices proven over many years. There are numerous examples of copper roofs which have been in place one or more centuries. Copper’s resistance to the elements ranks among the highest of modern roofing materials.

When properly designed and installed, a copper roof provides an economical, long-term roofing solution. Its low life cycle costs are attributable to the low maintenance, long life and salvage value of copper. Unlike many other metal roofing materials, copper requires no painting or finishing.

The ductility and malleability of copper make it an easy material to form over irregular roof structures. Domes and other curved roof shapes are readily handled with copper.

In recent years, new tools and installation methods have been introduced that aid in the quick, proper, and economical installation of copper roofs.
