If your Flat Roof has been leaking for along time and your decking is in poor condition we can help. Whether it is a wood framed cricket that needs to be reframed or a rusted out metal decking we have the experience to take care of both.
Typical rusty metal deck seen from the underneath side.
This rusty metal decking was compromised. It was in good enough shape that we could prime it with an epoxy primer to neutralize and lock in the rust and overlay it with a new metal decking.
This wooden cricket was in horrible condition. We removed the old roof and installed new wood framing and decking to make it as good or better than original.
What is EPDM Roofing? EPDM is an abbreviation for Ethylene Propylene Diene Monomer. It is the black rubber similar to what is used to make inner tubes for tires. EPDM has been around for many decades and is a reliable product. EPDM is available in both black and white. Thicknesses vary from .45 mil (about the thickness of a dime) to .90 mil. EPDM is typically installed as a fully adhered system which means the entire roof is glued to the insulation. The seams are sealed with a factory applied seam tape or field applied seam tape.
EPDM roofing before and after. This project required a tan membrane on the top of the walls that could be seen from the ground.
An EPDM roof in progress. You may notice all the round discs on the roof. These are called insulation plates and are used to hold down the insulation and in this case the installed roof. These are placed at specific intervals to make sure that the roof stays in place no matter what the weather brings.
EPDM roof that has just been completed. This EPDM came with the seam tape factory applied. This speeds up installation and alleviates installation errors on the most critical part of the roofing system.
What is DuroLast Roofing? DuroLast is a manufacturer that makes a PVC (Poly Vinyl Chloride) roofing membrane. The company started many years ago making pond/pool liners. They took that same technology and enter the roofing market. They have become so successful with their roofing concept that the name DuroLast is synonymous with PVC. DuroLast is installed on a lot of restaurants because of how well it performs in this environment. It holds up to grease better than any other membrane in the market place. However the membrane will perform equally as well for many other applications.
Before and after on a re-roof project. The membrane was installed over an existing built up roof. A ½” HD ISO was installed to separate the new roof from the old.
A new construction project from start to finish.
A recover project . Please note the two vents in the picture. Duro-Last is the only PVC system that utilizes 2 way vents to even out the pressure during high winds. This allows the roof to withstand winds that may damage other roofing systems.
What is TPO Roofing? TPO is short for Thermal Poly Olefin. It fits into the thermal plastics category. It is relatively new to the commercial market with the first installations happening in the late 90’s and early 2000’s. It is an economical choice which offers great benefits to the commercial building owner. The seams of the roof are heated and welded together, this means typical TPO seams are stronger than the surrounding field membrane.
This is a Fleece or fabric backed TPO. This material comes in 100 mil or 115 mil thickness and includes a 55 mil fleece factory mated to a standard TPO membrane. In this picture we see the TPO fleece membrane attached with beads of low rise foam adhesive. The fleece back TPO is an economical way to install a new roof over an existing roof, we call this a recover.
This is what a fleece back TPO roof looks like after installation. This is a picture of a TPO roof on a new construction project.
A TPO roof installed over an existing roof. This project included a lot of flashing around existing skylights. In this picture we see a walkway that was specified by the owner. Walkways help direct traffic and protect the roof for on going maintenance to the HVAC units.
What is a Metal Roof Retrofit? It involves installing a new flat roofing system over your existing metal roof. Add R value to the roof while removing all the leak points of seams and screw heads.
This is a picture of your typical old metal roof. In this case the metal had a lot of surface rust.
In this photo we see how an EPS (Expanded Poly Styrene) is used to fill the flutes of the metal roof. An 1.5” ISO board is installed over the flute filler to create a flat surface and add R value to the building.
After installation the roof is flat and attractive.
One of the challenges with this project is that the existing metal roof had been installed against this brick wall. This has always been a trouble area for this roof. As you can see the new system looks crisp and clean; this transition will last leak free for many years.
