KFS recommends that you do not attempt to remove snow or ice from the roof. Leave this job for the experts as damage can occur when unskilled workers attempt to remove the ice and snow. A properly installed SPF system should have minimal ice build up as the systems require adequate slope to drain. Large [...]
Before considering any type of insulation project you should determine where your problems are coming from by assessing the building condition. The best tool for testing this is a thermal imaging gun or infrared camera which shows temperature differences. These tools can show you if your walls or roof have poor or inadequate insulation, [...]
When you are looking for a Spray Foam Roofing Contractor you should ask certain questions to get references and determine their experience level. Most contractors can provide several references of past clients pleased with their work. You may also want to ask what trade associations the Contractor is a member of. Being a member of [...]
Q: When is the best time of the year to get my roof replaced or renovated with SPF?A: SPF systems require that temperatures be in the mid 40’s and rising to get optimum yield and performance. While there are three different reaction profiles available to foam contractors, our experience at KFS has shown that optimum results [...]
April and May is the time of year to check for debris and blockage in gutters and drains on your roof. Remove all debris and look for any damage that may have occurred over the winter months. Early detection and repair of problems can avoid the need for costly tear off and reroofing expenses
R-value is measured under laboratory conditions, but in the real world there are other factors that determine how effective a particular type of insulation may or may not be. Conduction, convection, and radiation all affect heat loss, but R-value only measures the first one, conduction, which is when heat is lost through solid materials. Radiation [...]
The Federal Trade Commission (FTC) considers R-value to be an integral part of spray foam measurement, and the FTC defines how R-value is reported and tested. The thermal performance of insulation is measured by R-value. R-value is a test performed under laboratory conditions and measures resistance to heat flow. The testing methods were developed by [...]
According to a recent article in SprayFoam magazine, spray foam provides a much better roof system than bituminous membrane roofing when it comes to withstanding storm damage. Spray foam provides a continous surface wth no edges, seams or joints that is self adhering, protects from water, and resists high winds, missile damage, and penetration. Here’s [...]
Never repair or patch a problem on a metal roof with asphalt roof cement. This type of cement becomes hard and brittle and does not allow the normal expansion and contraction of metal roofing. Asphalt cement is also very hard to remove causing much more prep work to get it off to allow the proper [...]
Finding a leak in a flat roof can be considerably more challenging than locating one on a slope. For one thing, sloped roof leaks tend to appear at or below the leak point, whereas a flat roof leak can spread out and seep through at a considerable distance from the actual leak point. One of [...]
