Make Choosing Your New Roofing System Easy:  

3 Things To Consider:  

The Roofing Membrane- What’s the type of material used?
The Installation Method- How is it attached to the roof?
The Seams- What is used to close the seams on the material?

1. Roofing Materials & Membranes


These are the types of roofing materials and single ply membranes Slagle Roofing and Construction offers to customers in the Southwestern Pa area.

 EPDM (ethylene propylene diene terpolymer):

Extremely durable synthetic rubber roofing membrane used in low-slope buildings. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas. EPDM is available in both black and white, and is sold a broad variety of widths, ranging from 7.5 feet to fifty feet, and in two thicknesses, 45 and 60 mils.

 TPO- Thermoplastic polyolefin:

Among the fastest growing commercial roofing products, it’s gained broad industry acceptance for their many performance and installation advantages.

 PVC- Polyvinyl Chloride: 

It’s a trusted membrane that has been performing admirably for decades with excellent resistance to rooftop chemical attacks including acids, oils and greases. Widely used as a white membrane, other colors are available through Duro-Last. (See Below)

 Standing Seam Metal:

This metal roof gets it’s name from the fact that it’s seams are raised or “standing.” As aesthetically pleasing as it is durable, standing seam metal may be a great option for your building.

2. Installation Methods


The installation method refers to how the chosen roof material is secured to roof decking so your building is protected. The following installation methods that Slagle offers are the most reliable in the industry.

Mechanically Fastened:

Considered an upgrade from ballasted systems (where a membrane is laid loosely atop the roof and covered with pavers or stones), mechanically fastened roofing systems are held in place by plates and fasteners that are secured through the membrane and into the deck. 

 Fully Adhered:  

Fully adhered roof systems offer the highest degree of stability and uplift protection. Unlike the mechanically fastened method, the membrane in a fully adhered roofing system is secured using an adhesive.

3. Seam Sealing Methods


Most human error and roof leaks originate here, in the seams. The chosen sealing method largely depends on the type of roofing membrane being used.

 Adhesives or Sealant Tape:

It’s a special-strength tape or liquid adhesive typically used in meeting the seams of an EPDM roofing system.

 Hot-Air Welding:  

A device uses hot air to heat the membrane until it melts and fuses together. This seaming method is commonly used in PVC and some TPO roofing systems.

  Hot Mopped or Asphalt:  

These methods are commonly used with modified membranes or when placing a roofing membrane over existing build-up roofing is appropriate. The asphalt is heated with a propane torch until it melts and fuses the membrane. Or, hot-mopping is laying a modified asphalt (a.k.a. mopping it) over the existing materials similar to how conventional build-up roofs were installed.


Slagle Roofing and Construction was welcomed into “The Presidents Club” and honored at Duro-Last’s National Seminar for outstanding achievement in quality workmanship and customer satisfaction.

Very few roofers in the Pittsburgh area can offer a cutting edge, pre-fabricated Duro-last roofing system.

Here’s why Duro-Last’s concept makes all other roofing systems obsolete in most cases:

Duro-Last Vs. “Other Options”


  • Pre-fabrication eliminates notorious “roofing failure” issues
  • Approximately 85% of seaming and roughly 95% of other critical areas (projections and perimeters) are welded under ideal factory conditions– not in the outdoor elements.
  • Your roofer can finish faster and you can return to business as usual, knowing you’ve got the world’s best roof.


  • Only the amount of material needed for your job is created. That means waste is dramatically reduced and your budget isn’t going home with someone as “left over” materials.
  • Covers ponding water and consequential damage (example: computers INSIDE building)  where others don’t
  • Warranty comes at no extra cost
  • Warranty covers repair + replacement where others only cover repairs


  • Because your roof is pre-fabricated in panels of up to 2,500 sq. ft. VS other types of roofing materials which are only available as roll goods in sizes ranging from 100 sq. ft. to 1,000 sq. ft.; there are much less seams, decreasing the risks of leaking greatly.
  • Did we mention most of those seams are completed under ideal conditions, inside a factory?
  • Other roofing systems commonly use glue as a seaming method. Duro-Last seaming is completed with hot-air welding methods.


  • Prefabrication can be used to address a particular structural or aesthetic design problem. Panel sizes, shapes and colors can be pre-planned and prefabricated to achieve desired visual results.

Metal Roofing:

More than 70% of federal government building projects request metal roofing because a properly installed, high performing metal roof pays for itself over time. Aside from the superior visual appeal of a metal roof, they’re extremely low maintenance, highly durable, 100% recyclable, and the best choice for contemporary or complex angles/shapes.
