Tin and copper metal roofs can be installed with soldered flat seams in a hydrostatic system.- Google Patents US6041770A - Bi-metallic control device Additional hydrostatic metal roof systems can be found on residential applications. These larger structures are more costly to design with a steep sloped roof assembly. Typically these metal roofs are found on larger pre-engineered metal buildings. These roof systems are capable of holding water without the roof system leaking. Hydrostatic metal roof systems are designed to hold water until it can drain. All other roof systems are considered steep sloped. The NRCA ( defines a low-sloped roof system as any roof with a slope less than 3:12. It is important to consider the slope of the roof when designing, installing and maintaining a metal roof system. Forgetting to consider the slope can be a major source of problems for metal roof systems. Metal roof systems can be installed in either a steep slope or low slope application. A separate design characteristic of a metal roof system is the slope. ![]()
