Spray Polyurethane Foam Roofing System

Yoder's Roofing Service uses Conklin’s Spray Polyurethane Foam (SPF), which is a closed cell roofing material that both waterproofs and insulates. In fact, as an insulator it has the highest R-value of any insulation material commonly available today.

The application of an SPF roof is a two stage process. An SPF roof is constructed by first applying a two component liquid (isocyanate and polylol) to the base roof surface. The roof is then covered in a second application by a protective surfacing material, applied either with by sprayer or by rollers.

Choosing an SPF roof system not only ensures a leak free roof. It also adds an exceptional R-value to the roof, lowering energy costs dramatically!

Unlike other roofing systems, SPF is renewable. It’s a long lasting system which will last for decades, and every 15 to 20 years its life can be extended with a thorough pressure cleaning and re-application of protective top coat. That makes it one of the most cost effective roofing solutions available over the long term.

Apply it on existing roofs surfaces

SPF can also be applied over other existing roofing surfaces. SPF can be applied directly over BUR, modified-bitumen, concrete, wood, asphalt shingles, clay tile, and metal. SPF adds very little weight to the roof (about 8oz. per square foot at 1 inch thick), there is usually no need for tear off before its application, except in cases of basic damage to the foundation material.

Benefits of a Spray Polyurethane Foam Roof

1). Seams are one of the major sources of leaks in roof systems and SPF roofs are totally seamless.

2). Water does not travel laterally in SPF roofs as it can in BUR (Built-up roofs with multiple plies of roof felts laminated together with bitumen) or single-ply roofs. A leak in the top membrane of a BUR or single-ply roof will create the spreading of water, saturating the insulation and causing multiple interior leaks. With SPF, even if a hole is punched through the entire two inch membrane, water movement will be restricted to the hole. In most cases repairs can be made with a tube of caulk.

3).Because the SPF roof is lightweight, permeable and fully adhered, normally an old roof does not need to be removed in order to apply a new one. If underlying areas of saturated insulation are found, minimal tear-off may be required.

SPF Application
Recommended for application over these surfaces:
  • EPDM/BUR/Mod-Bit
  • Concrete
  • Metal
  • Wood
  • Composite Decking

Life Expectancy of Sprayed Polyurethane Foam Roofs

There are no known end of service life figures for SPF. Generally, if SPF is pressure washed and sprayed with a top coat every 15 to 20 years this system will last decades. SPF shows little sign of deterioration or change in physical properties even after 30 years.

Condensation Concerns of Sprayed Polyurethane Foam Roofs

SPF provides a continuous air barrier preventing moisture through air leakage, minimizing dew point problems and condensation within the building envelope avoiding thermal bridging, resisting heat movement in all directions and providing reliable performance under varying conditions.

SPF roof systems can be applied directly over BUR, modified-bitumen, concrete, wood, asphalt shingles, clay tile, and metal.

Since it adds very little weight (about 8oz. per square foot at 1 inch thick) SPF is used as a recover system over existing roofs without the need for tear-off. This reduces the amount of construction debris in landfills. Also if no tear off is needed, exposing the interior of your building to the elements is eliminated.

Renewable System

Another major advantage in a Sprayed Polyurathane Foam roof system that does not exist with any other roofing system, is the SPF is a renewable system. While BUR and single-ply roofs must be removed and replaced after their usable lives, SPF roofs can be repaired and recoated to offer an indefinite life expectancy coupled with the energy savings and reduction of in house maintenance costs.

The SPF roofing system maintains a tremendous long term cost efficiency advantage over all other roofing systems.

Reduce Cooling Expense by up to 30% and Recoup your Costs

Energy Star Roof Roof absorbs suns heat

The average roof absorbs a large portion of the sun's ultraviolet rays as heat. Conklin's white SPF roofing system reflects 85% of the sun's heat, cooling your building and saving you as much as 30% in air conditioning costs.

A Great Return on Investment

A great return on investment is another important reason to install Conklin's SPF Roofing System. Many satisified builing owners discover that a Conklin roof pays for itself during the warranty period in lower air conditioning costs. Federal tax rebates, tax credits and deduction may also offset your investment. Check with your local utility company, tax advisor, or visit www.energystar.gov for additional details.
