Somerset County Roofers: Article About Benefits Of Insulation
When a structure is built with a nearly flat roof, drainage of rain and melting ice or snow can be challenging. When experienced Somerset County roofers are repairing or replacing the home's roofing, some modifications can be made in order to facilitate leading moisture off the roof's surface and into the gutters and downspouts. These changes can help the rooftop last longer and experience fewer problems like ice dams and water leaks.
In order to create a slope where there is currently none, roofers look to tapered foam roofing boards. These boards act both as a form of insulation as well as a substrate upon which other materials can be laid. The foam boards are created from extruded polystyrene or polyisocyanurate, which are plastics designed to be able to withstand heat and moisture. These boards are ideal for shallowly pitched or no slope roofs, as they act as an insulator in place of having attic insulation.
The roofers will locate the rooftop drains and create layers of the tapered boards to direct the water toward each drain. The roof may be divided into zones, with two or even four slopes created with the boards.

If getting the rain to move across the surface is a problem, the roofers can create roof crickets. This is done by trimming the polyisocyanurate foam into triangular shapes.
The boards are affixed to the roof's surface using regular roofing nails and a nail gun. The number of nails needed depends on the size of each board. Some foam board manufacturers recommend the use of roofing screws if the roof is being installed in areas prone to high winds. Adhesives are used between each piece of foam to create a watertight seal.
Foam boards are produced with a slope of one quarter of an inch per foot. If a greater slope is needed, the roofers will stack two or more boards. The greater the slope, the faster and more effectively rain, snow or ice can make its way toward the roof's drains.
Once all of the foam boards are in place, then a waterproof barrier or radiant barrier can be installed on top of them. Roofing felt can also be placed on top of the foam boards. After all of these layers are together, then the final layer of roofing material can be put on. Shingles, tiles or a built up bitumen roofing system can all work well with the use of tapered foam roofing boards.
