McDonough Spray Foam Roofing

Spray polyurethane foam is applied as a liquid, which then expands many times its original volume, creating a high-density roof covering that’s resistant to both impact and water damage. With a 6.2 R-value and 85% reflectivity, SPF coatings deflect so much of the sun’s heat that property owners recoup their application costs in just four to seven years through reduced cooling expenses. Unlike other heat-reflective materials, however, SPF is also insulation, reducing heat-loss in wintry weather and lowering overall heating costs. This Conklin roofing product can be applied over existing roofs of good condition.

Advantages of Using SPF

Improved Waterproofing

Since SPF is installed as a liquid, when it expands, it seeps into and fills cracks, gaps, and crevices in the materials below it. It’s naturally waterproof (not just resistant) — so much so that the U.S. Coast Guard has accepted it as a flotation material, as well as a roofing system. 

FEMA (the Federal Emergency Management Agency) even recommends spray polyurethane foam as a building material to reduce flood damage.

Adds Structural Strength Without Significant Weight

According to SPF tests performed by The National Association of Home Builders (NAHB) Research Center, spray foam insulated wall panels increased the racking strength of both wood and metal stud walls from 70% to 200%. When installed to the exterior and roofs of buildings, SPF reduces building sway in high winds, lessening the likelihood of corners being caught and torn from the substrate. Essentially, spray polyurethane foam “glues” the entire structure together, significantly increasing rigidity and tensile strength, while still allowing some flexibility for building movement without cracking.

Can Withstand Hurricane-Force Winds

SPF bonds so tightly to a substrate that it’s nearly impossible to pull off in high winds. It’s also a natural shock-absorber. Even in gale-force winds, heavy objects like tree branches, building materials, and concrete tiles typically cause only superficial damage to the spray foam substrates, which resists peel off and provides continued water protection to the interior of the building. After Hurricane Katrina, which destroyed a vast area of the Mississippi Gulf Coast, it was noted that many buildings sustained little or no damage in the SPF-insulated sections, while areas that lacked SPF were often loosened and ripped away due to pressurization and high winds.

Easily Correct Damaged Substrate and Poor Drainage.

Like poured concrete, SPF can “cover a multitude of sins.” Small cracks and gaps in substrates, pipe/vent openings, and flashing are filled and covered during the foam expansion process. Some roofs can even have drainage issues corrected or improved by a knowledgeable and experienced technician applying SPF. Likewise, future repairs to damaged SPF can be efficiently completed with a compatible sealant or by replacing the damaged portion and installing more foam.

Roof protection and maintenance are some of the most effective ways to avoid common and expensive commercial property costs.
