EPDM Roofing in Minneapolis St Paul MN
EPDM is very much like most single ply roofing materials, in that it has a single membrane protected with some type of overcoat, except EPDM is made of rubber instead of the plastic TPO roofing uses. EPDM roofing in Minneapolis has a great reputation for being durable, and long lasting, especially in commercial roofing. When EPDM is installed properly, with seams taped and a complete flashing system installed around all of the roofing components, it can easily last for 30 or more years with little maintenance. The only really attention it will need is to the seams, that are top coated with an additional adhesive designed to keep moisture out. Left out in the elements, this adhesive will blister and crack, needing a simple, routine reapplication.
EPDM roofing can be installed mechanically, fastened, or ballasted, that is to say, held in place with stone. Ballasted applications are very economical for large surface areas, provided the structures can support the weight of all the stone. This type of roofing material comes in thicknesses ranging from 45 to 90 mills, and can be reinforced with polyester scrim, or without it. However, only the 90 mil membrane is eligible for the 30 year warranty rating.
When roofing material of this sort is applied “fully adhered”, this means that the ply has been completely glued down, or somehow secured with adhesives across the entire surface. Because the adhesives can be altered depending on the weather, these types of roofing will only warrant a 15 to 20 year warranty.
When EPDM is mechanically fastened, this means that the sheathing ply is held in place with some type of fasteners. Typically, they are button head nails or screws with plates. Roofing nails are not recommended as they will obviously punch holes in it, and compromise the integrity. Mechanically fastened roofing materials will normally carry a 10-15 year warranty from most manufacturers.
A ballasted roofing system is one that is held in place with a layer of river rock, manufactured concrete pavers, or whatever is available that has enough weight to hold it in place. These roofing systems will only carry a 10 year warranty as they will do the job, but leave the potential for compromise because of the potentially sharp objects on top of it.
