The strength for both SureCoat and silicone are similar at 2 gallons per SQ (100 SF) with a psi tensile strength of 480 to 490 psi. 2 gals per square is only a “cool roof conversion” with both SureCoat and silicone.  To obtain a warranty for either system, the systems must be installed per manufacturer’s specification.  Roof specifications differ depending on the roof type applied to.  With other manufacturer’s this requires separate products such as basecoats, primers, mastics and an entirely different product for the reflective topcoat, often incapable like “oil & water”.

SureCoat can be cleaned with SureSkrub to regain lost reflective points because in the case of the SureCoat Roof System, the lowered reflectance is due to dirt.

This is not true of silicone roofs.  Silicone does not hold up to UV and heat. The overall loss in Solar Reflective Index (SRI) for silicone and acrylic coatings as well as traditional single-ply roofing membranes is from UV degradation in addition to ordinary dirt.  The dirt, degraded rubber and plastics are nearly impossible to remove without harsh cleaners on these types of roofs because the dirt begins to embed itself in the material as it degrades.  If you were to even power wash an acrylic roof, the acrylic roof paint would begin to come up, exposing the unlaying roofing materials which are unable to emit any UV causing damage.

All the numbers used in comparing data come from real manufacturer published literature available publicly online.  UV Stability, Permeability and SRI all contribute to the Longevity and overall Sustainability of a Roof System.
