Flat roof systems- from a small flat roof to a huge commercial building. Excel Roofing has you covered.

We specialize in

EPDM (ethylene propylene diene monomer)

EPDM synthetic rubber roofing membrane is extremely durable, making it a smart choice for commercial low-slope or flat roofs in any climate.

Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made from polyprophylene and ethylene-propylene rubber polymerized together. It is typically installed in a fully adhered or mechanically attached system, allowing the white membrane to remain exposed throughout the life of the roof.

Modified Torchtown

Torch down roofing is a type of roofing that consists of levels of modified bitumen--similar to asphalt--heat-adhered to layers of fiberglass. Used only for flat or nearly-flat roofs, torch down roofing is an excellent means of preventing moisture build-up and obviating the need for constant maintenance.

Metal Roofing- We are experienced installers of several metal roofing systems for both residential and commercial.

Commercial Flat Roof Materials and Coating

Excel Roofing offers GAF, Versico and Mulehide TPO and EPDM rubber roofing products for new installations, repairs and commercial roof replacements. Fluid-applied roofing systems are a popular alternative to flat roof replacement and provide seamless waterproofing. Our experienced flat roof contractors can also apply polyurethane-based Neogard roof coating to extend the life of your low-slope roof.

For hardy, long-lasting weather resistance we install built-up roofing (aka asphalt & gravel roofing) and modified bitumen waterproof membranes on commercial buildings. PVC single ply roofing is also available as a low-cost, low-maintenance commercial roofing material.

COMMON COMMERCIAL ROOFING PROBLEMS

Poor Drainage

The Basics: Heavy rain and snow on a commercial roof can form puddles which wear away at the roof material. The water then works its way inside, creating a leak.

WHY it happens: Many commercial buildings have flat roofing. A perfectly flat surface will not drain naturally after it rains or snows. Standing or ponding water can lead to expensive leaks.

HOW to prevent it: Professional roofing installation from Excel Roofing on a “flat” roof will include low slopes with a very slight pitch to drain water. Other features like flashing materials and gutters will also promote better drainage.

Leaky Flashing

The Basics: Flashing weatherproof material is used to reinforce roof joints and seams. Leaks around flashing can weaken already vulnerable areas of the roof.

WHY it happens: Chimneys, windows, and HVAC systems all create gaps in roofing material requiring flashing. If the flashing is not installed correctly, it won’t keep water out.

HOW to prevent it: Excel Roofing will recommend the right material and style flashing for your roof. will give you an estimate on installing and replacement so you know the costs upfront.

Membrane Shrinkage

The Basics: Certain roofing materials like PVC or EPDM membranes can shrink under extreme conditions.

WHY it happens: DIY roofing projects may mix incompatible materials, leading to a weaker membrane more prone to shrinkage. Poor installation may result in an ill-fitting roof with shrunken sections.

HOW to prevent it: Professional roof installation will result in a better fit with the right materials, reducing the chances of shrinkage.
