Low Pitch Metal Roof Leaking

Metal roof systems can be installed in either a steep slope or low slope application.

Low pitch metal roof leaking.

Can metal roofing be used on a low slope pitch roof. We counted 90 stalagmites on the surface of the ice rink from drips coming from the leaking roof. Forgetting to consider the slope can be a major source of problems for metal roof systems. Of all roof problems leaks are among the most insidious and the least welcome.

If your ceiling has a plastic vapor barrier between the drywall and the attic insulation push the insulation aside and look for flow stains on the plastic often water runs to openings in the vapor barrier such as at ceiling light fixtures. Some roof leaks are tough to locate. A common place for a metal roof to leak is at the very edge of the metal panels. Metal roofs are low pitch and when water rolls of the edge it will follow t.

Once water enters the building it can damage inventory and contents resulting in a major expense to the owner. Roof leaks can result from installing laps against the natural flow of water incorrect flashing and adhesion failure at the seams. It is important to consider the slope of the roof when designing installing and maintaining a metal roof system. Low slope metal roofs have been a preferred roof covering for commercial institutional and industrial buildings for years because of their ability to protect against the elements to allow water to drain away from the roof surface and to keep building contents and occupants dry and.

Low slope metal roofs require less material which reduces the overall load on the building s structure. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. In country with heavy snow and tough winter days the metal roof minimum slope is recommended to be 1 12. Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs.

What are low slope metal roofs. Some metal building manufacturers will not warranty a roof with a 1 4 inch slope. There are some opinions that standing seam metal roof minimum slope is 12 but it increases the possibility of leaking on the few first days of snow arrival. Sometimes the water shows up at a ceiling spot distant from the leak.

When the snow piled up on the roof melting occurred and ice dams resulted in water ponding 3 inches deep.
