Restoration of a leaky single-ply roof.

If you have ever wondered, “What would the power company do to save money?” Now you know.

They would call MAC Roofing Services to install a highly reflective 100% silicone restoration coating.

As can be seen below, this building structure had an old leaky rubber/single ply roof and just like an old tire lying out in the desert heat, in the one of the harshest Ultra Violet climates on earth, it failed.  The rubber dried out and developed pin holes and then it leaked, like a colander straining peas.

Yes! NV Energy gets a power bill every month too and while they may not want you to know how they lowered their own power bill, now you know.  The application of a 100% silicone coating over single ply roofing is a sustainable restoration solution.  It seals without fail, every pinhole, seam, and potential crack 100%.  It adds tremendous reflectivity as can be seen in the photos below to an almost blinding level.

Fluid applied roofing may be the most cost effective solution for any roof restoration project but not all coatings are water proof.  Some coatings are water based and provide little moisture protection but may be reflective while other coatings are waterproof and reflective.  Make sure you are choosing the correct coating for your specific application and needs.  A coat of paint is not a roof.

Not all coatings are created equal and as with any roof, it is the details that matter.  When looking at any metal roof, almost the entire leak potential is at seams, joints and at roof penetrations.  The initial phase of this project requires using a polyester fabric reinforcement applied into two coats of a solvent based Uniflex Coating at all of the seams, pipes and penetrations.

When choosing the correct coating for this, or any application, it is important for the consumer to understand that most elastomeric coatings are water based acrylic coatings and provide little protection from water intrusion.  They may be a pretty white color and reflect the heat well but are intended for that purpose only.  Given that they require only soap and water to clean them up, when apply that same principle to rain and potential pooling of water, you can figure it out from there.

Bu using a solvent based material at the details, it eliminates the potential of rain water degrading and washing away the thickness of the coating prematurely.  At completion of the potential leaking details have been repaired properly including all of the seams, the entire building can then be coated white with a much more affordable acrylic coating making this a cost effective and leak free HYBRID ROOF DESIGN.

Another hybrid benefit on this and many other projects also allows us get creative at details such as the HVAC units that are roof mounted as can be seen in the fourth photo of this set.  We have used spray applied poly-urethane foam to form a cricket at the rear of the HVAC unit’s plenums in order to eliminate the ponding of water at this detail.

Simply by using 3 different but necessary fluid applied systems, we have custom created a roof that conforms to all of the folds and bends and details of this roof in a seamless monolithic fashion.   Fluid applied roofing systems are the only seamless roof solution on the market.

The added reflectivity of the coated roof has lowered the surface temperature of old steel roof by 47 degrees in the summer months reducing the radiant heat transferring into the building.
