DURO-LAST

The Duro-Last® single-ply roofing system is ideal for any flat or low sloped, new or retrofit application. Since 1978, over two billion square feet of Duro-Last® membrane have been installed on buildings of all types throughout North America.

Here’s a Letter of Commendation from Duro-Last’s VP of Sales and Marketing, Steve Ruth

Here’s why we prefer Duro-Last®

Every Duro-Last roofing system is manufactured in a controlled factory environment to rooftop specifications. This eliminates up to 85% of rooftop installation seaming and ensures an excellent fit, delivering worry-free, leak-proof, long-term protection.

The highly- reflective Duro-Last white membrane is saving energy and money for building owners and managers throughout the United States. A new Duro-Last roof can help facilities obtain credits toward LEED and LEED-EB certification. The Duro-Last system is resistant to fire, chemicals, grease, high winds and punctures and easily accommodates wide temperature extremes.

Installation is quiet, fast and safe without loud machinery, hazardous materials, noxious fumes, hot tar or mess. A new Duro-Last roof can often be installed over an existing roof without an expensive tear-off.

Duro-Last protects commercial and industrial buildings with our comprehensive 15 year no dollar limit (NDL) warranty that is transferable, has no exclusions for ponding water and provides coverage against consequential damages that result from defects in the Duro-Last material and/or installation workmanship. Duro-Last also has 20 year warranties available.

Founded by John R. Burt in 1978, Duro-Last is the world’s largest manufacturer of custom prefabricated roofing systems. In the mid 1970s, Burt can up with the inspiration that would lead him to Duro-Last. At the time, he owned a company that manufactured vinyl swimming pool liners and came to the realization that if a liner kept water inside the pool it should also keep water out. From that simple premise, the Duro-Last single-ply roofing system was created.

Duro-Last’s corporate leadership continues to direct the business with the same spirit and commitment that John Burt embodied. “My philosophy is this- if I’m going to manufacture a product, that product better be the best of its kind and do what it’s supposed to do,” he said.

 

BUILT-UP ROOFING

Built -Up roofing consisting of multiple piles of roof felts laminated together with bitumen. Built-up roof material can consist of bitumen-saturated felt, coated felt, polyester felt or other fabrics. A surfacing is generally applied and can be asphalt, aggregate (gravel or slag), emulsion or a granule-surfaced cap sheet.

Built-Up Roofing is one of the oldest and most reliable ways of installing a new roof. It was first known as composition roofing and started in the 1840’s. B.U.R.’s come in two basic types, asphalt and coal tar, and three basic components:

1. the waterproofing component
2. the reinforcing component
3. the surfacing component which is used to protect the other components from the elements The roofing membrane is protected from the elements by a surfacing layer, either a cap sheet or gravel embedded in bitumen or a coating material.

The most common surface for a Built-Up Roofing, particularly in the west, is a fiberglass mineral surfaced cap sheet and represents 40 percent of the fiberglass cap sheet market. It offers a number of advantages. It has a white granular look, it is cost effective, and is relatively maintenance free.

MODIFIED BITUMEN ROOFING

Modified Bitumen was first developed and utilized in Europe in the 1960s. This membrane is manufactured in uniform sheets comprised primarily of polymer-modified bitumen reinforced with one or more plies of fabric, or ply sheets. The fabrication can include polyester, glass, or a combination of the two. When applied in roofing, the finished version may be comprised of several sheets of modified bitumen and asphalt to create a uniform matrix.

When used in conjunction with a thermoplastic polymer, APP (Atactic Polypropylene), a uniform matrix is created within the modified bitumen sheets. This matrix increases the bitumen’s resistance to ultraviolet (UV) light, increases its flexibility in extreme temperatures, and increases it resistance to water penetration. This added resilience and enhanced durability under extreme conditions makes modified bitumen a prime choice when there may be movement or deflection of the underlying deck of a roof.

Modified Bitumen roofing systems create watertight barriers that perform for many years at a time due to the multiple layers. When built-up, these layers of bitumen exhibit exceptional resistance to conductivity of heat between the exterior and interior of the building. This generates noticeable reduction in heating and cooling costs. The thermoplastic polymers used in the modified bitumen make it more fire resistant as well. The technology employed in creating this roofing system makes it affordable and easy to generate as well.

 

Roof Coating 

Geisler Roofing and Home Improvement - Your Environmentally Friendly, Energy Saving Answer to a Leaking Roof that Wastes Energy 
Geisler Roofing and Home Improvement roof coating gives building owners a number of benefits including waterproofing the roof substrate, helping to prevent roof leaks, and creating more energy efficient interior climate control. A roof coating can be used for flat roof maintenance and flat roof repair. When used for building roof maintenance, roof coatings can qualify for a 100% tax deduction the first year!

Additional Benefits of an Elastomeric Roof Coating 
More benefits of a roof coating are being seamless; seams are one of the most common places where a roof leak begins, bright white and reflective; the bright white reflectivity of the roof coating makes the sun’s harmful UV rays bounce off the top coat. This also reduces thermo-cycling, the destructive process where the sun’s heat wears down the roof prematurely due expansion and contraction.

**Seal and Protect Your Commercial Flat Roof **

Elastomeric roof coatings will seal and protect almost any roof substrate including modified bitumen roofs, smooth built up roof, gravel built up roof, spray foam, concrete flat roofs, metal roofing, EPDM, single-ply, wood and steel. A roof coating is rubber membrane that is applied as a liquid and requires minimal roof top equipment. This provides the building owner with a business to continue under usual condition during the roof coating application process. After the roof coating application is complete, most root coating experts can offer a long term, roof coating manufacturer material and/or system warranty to keep your mind at ease.

A roof coating is more than just a great way to protect your investment, it’s also an investment in the environment. A roof coating can restore a dilapidated, deteriorated traditional roof to a good as new condition without the need to tear the old roof off. The old roof becomes the base upon which the roof coating adheres, forming a new, stronger, and waterproof roof surface that is more energy efficient and easier on the environment.

Alternatives to Roof Coating 

There are some cases where the roof has deteriorated to the point where is must be torn off and replaced and simply applying a roof coating will not be the best choice. For these situations, there are a few alternatives, the best of which is a bright white, cool roof single-ply roof system. These roofing systems are based on the same technology behind cool roof coatings and can offer many of the same benefits as a roof coating, saving energy dollars through reflectivity and admissibility.

TPO

With an ever increasing demand for durable yet lightweight and energy efficient roofing systems TPO roofing systems were created specifically to meet that demand. Because these single ply membranes offer superior resistance to UV damage, the elements and chemical exposure; TPO is quickly becoming the commercial roofing system of choice- especially in Central Kansas.

TPO is short for Thermoplastic Polyolefin which refers to polymer blends containing various mixtures of rubber, polypropylene, polyethylene and reinforcing filler. TPO roof membranes are a blend of polypropylene and ethylene propylene polymers encapsulating a reinforcing sheet of polyester membrane.

TPO membrane is modified with UV absorbing agents, flame retardants and other proprietary substances designed to produce superior physical properties.   At Geisler Roofing, we value your time.
