Roofing Materials


Asphalt Shingles

This is most commonly used on residential homes in a shingle form and comes in a variety of colors and patterns from the old traditional 3 tab shingle to a more modern dimensional shingle.

Clay or Spanish Style

Nothing matches the classic look of real clay tiles. Concrete Roof Tiles are only pretending to look like clay tiles, but often can’t match the natural color blends and style of clay tile roofs.


Metal roofs seal out water, are strong against winds, are easy to clear snow off of and are totally resistant to fire, mildew and rot. A metal roof is guaranteed to reach its warranty period in full force. These advantages are becoming increasingly apparent, as the dramatic rise in the popularity of metal roofs tells us. Responsible for this is also the growing variety of metal roof materials, no longer simple


Slate roofing is beautiful and long lasting, gracing castles in Europe and homes in the U.S. Slate does becomes brittle, falls dangerously, and requires special techniques to affix and repair. A new option for a roof of slate is now available for your new home or building.Slate roofing is one of the most distinguished building products that I know of. It graces many of the most impressive buildings in the world. Cathedrals, palaces, residential homes, and castles have incorporated this long lasting building material as a weather shield. In fact, it was the king of roofing materials at the turn of the twentieth century.

Rubber Roof & EPM Rubber Roofs

Sometimes called synthetic or thermoset rubber, rubber membrane roofing is made of large flat pieces of synthetic rubber materials that are welded together at the seams to form a continuous membrane. The final thickness of rubber membrane roofing is usually about 0.75-1.5 millimeters, and it is highly suited to low slope and flat roofing surfaces.




Common Roofing Problems

Missing Shingles

This is the most common signs aside from leaks that you need a new roof. You’ll find them in your driveway and in your yard following significant rain and winds.

Missing Granulars

Over time the granular surface of the asphalt shingle loosens and wears off. Once worn down to the asphalt base, the asphalt shingle will tend to dry out and crack exposing the underlying roof.

Curling Roof Shingles

This happens as a result of poor ventilation or dried out asphalt shingle base. When a roof gets to this stage its important not to walk on it if possible.

Blistered roof shingles

When you see this, your shingles have needed changing for some time now, there cracked and look like bubble wrap, and in most cases dislodged off the deck, allowing water underneath.

Wind Driven Roofing Problems

Multiple layers of shingles, in the past contractors over the years have added multiple layers of shingles, this however we have learned over time is not the way to go, as the bottom layer of shingles cooks the top layers causing bubbling and blistering. Additionally this voids out any shingle warranty by the manufacturer.
