Whereas a 60 mil membrane is 0 06 inches thick and so on.

How much the flat roof thickness.

Ultimately a flat roof should play a part in a total architectural composition and has the ability to enhance the aesthetic and practical outcomes of a home. Roof sheathing comes in grid marked 4 by 8 foot sheets and should be installed perpendicular to the frame. Built up roofs or burs also called a tar and gravel roof is a well established and popular style of flat roof that is made up of alternating layers of roofing felt or fiberglass and asphalt that is applied with heat which combine to make a long lasting sturdy roofing system. The most common thickness is probably 60 mils.

The problem with metal roofing gauge is that there is a wide range of tolerances. For example one company might sell a product as being 24 gauge but in reality the thickness of the metal could vary from 0 018 to 0 0335 based upon exactly how that company looks at things and how big of a tolerance they allow for. The typical thickness range for sheathing is 3 8 to 3 4 inch. A low slope roof is anything under 2 inches of fall per foot.

A mil is a unit of measure where 1 mil is equal to 0 001 inches. A built up roof for example will typically include the built up membrane itself with or without gravel as well as some kind of insulation and cover board which will vary in thickness from roof to roof. Low slope or flat roofs are another story. Sheathing should be a minimum of 19 32 inch thick.

Most flat roofs are typically not as long lasting or durable as sloped ones because the latter shed snow and rain a lot quicker. So why have all the companies i ve asked so far just wanted to put a random and insufficient thickness on. When it comes to estimating the weight of an existing roof field verification of the in place construction is necessary. So a 45 mil roofing membrane is actually 0 045 inches thick.
