We love a challenge

The Bierstube

The Bier Stube in the Village of E. Davenport was one of more memorable commercial projects. What a roof job! We removed 4 layers of existing roof material, including the original roof from the 1800s, and we installed a completely new roof deck! We are very appreciative to the Bier Stube for calling Green Valley.

Long-wearing Metal Roofs


Metal roofs are quickly gaining in acceptance due to their durability and the fact that they handle the ravages of severe weather particularly well. Green Valley can provide expert installation of virtually any type of steel or aluminum roof. We specialize in the installation of standing seam roofing and cladding.

EPDM Roofing

Even EPDM!

What's EPDM? EPDM is also known as Ethylene Propylene Diene Monomer. That's such a fun name to say! It's really just a long chemical name for a type of durable, long-wearing rubber. Itg's similar to the rubber in a bicycle inner tube, but thicker. This is a great choice for flat roofs with very little pitch and is very common in flat commercial applications, and even in some unusual residential applications, like the roof pictured to the left.

EPDM is available in both black and white, and is sold a broad variety of widths, ranging from 7.5 feet to fifty feet, and in two thicknesses, 45 and 60 mils. EPDM can be installed either fully adhered, mechanically attached or ballasted, with the seams of the roofing system sealed with liquid adhesives or specially formulated tape.

According to the EDPM Roofing Association, EDPM has been shown to "have the roofing industry's longest average service life. Characteristics that contribute to this superior overall system performance include:

  • Cyclical membrane fatigue resistance;
  • Proven hail resistance;
  • High resistance to ozone, weathering and abrasion;
  • Flexibility in low temperatures;
  • Superior resistance to extreme heat and fire;
  • Thermal shock durability; and
  • Ultraviolet radiation resistance

EPDM roofing has also been proven to be highly resistant to wind damage when the correct material is chosen and installed according to manufacturer instructions.

That's where Green Valley comes in. We install commercial roofs with the same expertise and attention to detail that our residential customers enjoy!

Difficult architectural roof lines are our specialty

The Cliff

We nicknamed the Second Baptist Church in Rock Island "The Cliff" because of its unique architecture. This roof is steep, big, and angular. This was a challenging project with limited access to the rear portions of the building and a high ridge-line at 65ft above the ground. A roof any steeper would be called siding!
