TPO Roofing


TPO membranes are single-ply roof membranes manufactured from ethylene propylene rubber. TPO has exploded in popularity in the previous 10-15 years in the St. Louis market. TPO is typically white in color, but it can be special ordered in a variety of colors.

TPO can be of different thicknesses 45 mil, 60 mil, or 90 mils. The industry standard on all of our proposals is 60 mil. The width of the rolls is typically 10' and has a length of 100'. TPO single-ply roofing can be installed mechanically fastened or fully adhered.

When mechanically fastened, the materials are loose-laid, fasteners are placed on the seam, and fastened typically every 1'-1.5'. The next sheet overlaps the previous one and is hot air welded to the first. This process is followed from the gutter to the peak of the roofing system, then the walls and flashing details are installed. These are all typically fully adhered to.

When fully adhered, a process of loose laying the materials in the position desired, folding roughly 50% of the way, and gluing the materials down to the insulation/substrate. Fully adhered is typically a slower process, this is why it will cost more than a mechanically fastened roof.

Green Roofing


The big thing these days is green roofing.

The newer systems such as the white TPO, EPDM, and other elastomeric coatings, say that they are energy savers due to the white reflective coatings.

This is true, but you have to calculate how much savings they actually are. If you have more Heating Degree Days (HDD) than Cooling Degree Days (CDD), this is just a facade.

The real solution is insulation. The St. Louis city code for commercial flat roofing is minimal base insulation of 2-3 inches thick (giving you an R-value of 20-30). It doesn’t matter how many heating days or cooling days you have; it matters what your R-value is and what type of roofing system protects it.

We understand the importance in the summer months to keep the sun's damaging rays from harming your roofing materials & heating your building with the “island effect.” That is why we offer reflective coatings, white cap sheets (hot tar or torch down applied), and light-colored gravel (also protects against hail damage).

Built-Up Roofing


Built-up roofing, or BUR, is one of the oldest and most common roofing systems in America.

BURs have lasted 50-60 years before repairs or replacement, and some roofs today have BURs that have lasted over 100 years! The reason is that these systems consist of multiple layers of fiberglass mats (often known as felt) embedded in asphalt and sandwiched in between additional layers topped with asphalt once again.

This is why a BUR system performs well in extreme wind, snow, cold, and heat. These systems are considered the “Granddaddy” of flat roofing.

They have a proven track record of over 100 years. No other commercial or residential flat roofing system can say that.

Multiple Ply Roofing


Unlike single-ply roofs, built-up roofs are just that – multiple layers of roofing material as a waterproofing membrane and a weathering surface.

Single-ply roofs such as TPO & EPDM are roughly 49-90 mils thick. A single ply of felt is 24-32 mils thick. It is industry standard to do a base and 2-4 plies of roofing when doing a brand new hot tar roofing system or a roof over.

The roofing base is 40 mils thick, and the base sheet will provide additional strength, moisture resistance, and asphalt uniformity when used as a first ply over a nailable, non-nailable, and insulated substrate. In addition, it will perform as a venting base sheet when spotted and/or sprinkled mopped over plastic foam insulation.

So let’s recap: a single-ply roofing system of TPO & EPDM is 49-90 mils of protection, and a hot tar system is 88-168 mils of protection plus the actual protection of the asphalt itself!

Modified Torch Down Roofing


Modified bitumen or “torch-down” roofing got its name from the installation process, which is done by torching the sheets to the roofing base sheet. It is like a large rubber sheet that’s actually vulcanized onto a fiberglass base sheet.

Highly recommended for most flat roofs that are inaccessible to a hot tar kettle and/or other necessary equipment that may interfere with operations of your property during the installation process. There are options available to even combine a brand-new hot tar roof with a torch-down roof.

This gives you the best of both worlds with amazing warranties on materials and labor. The modified bitumen rubber is combined with high-quality resins. In turn, this makes the material resistant to damage from UV rays. It will not heat up and melt in the summer months. Once installed, if done properly, it has a watertight seam that is vulcanized to the roofing substrate.

Unlike loose-laid systems that are only sealed at the seams. Torch-down roofing is easy to repair and typically is low cost due to the fact no big expensive equipment is needed for repairs. There are different types of modified bitumen to install. You may choose a smooth rubber or one with granules that come in many different colors (white, black, brown, etc…).

Once the roofing system is installed, there are also many different options to choose from. You can go with an entire line of energy star-rated coatings that will reflect the sun's damaging UV rays and extend the material and labor warranties.
