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 different thickness 45 mil, 60 mil or 90 mils. Industry standard on all of our proposals is 60 mil. Width of the rolls are typically 10' and have a length of 100'. TPO single ply roofing can be installed mechanically fastened or fully adhered.

When mechanically fastened, the materials are loose laid and fasteners placed on the seam and fastened typically every 1'-1.5'. The next sheet overlaps the previous 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.

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.

Worker applies pvc membrane roller on roof very carefully. Correct welding with hand-welder, corner.

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), light-colored gravel (also protects against hail damage).

Built-Up Roofing

or BUR

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

BUR’s have lasted 50-60 years before repairs or replacement, and some roofs today have BUR’s that have lasted over 100 years! The reason why is that these systems consist of multiple layers of fiber glass 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

with Hot Tar

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 ply’s 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 substrates. In addition, it will perform as a venting base sheet when spot and/or sprinkle mopped over plastic foam typed insulation.

So let’s recap, a single ply roofing system of TPO & EPDM are 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

Rubber 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 damages 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 suns damaging UV rays, and extend the material and labor warranties.
