Flat Roof Condensation Solutions

Essentially thermal insulation can either be placed above or below the structural roof deck or waterproofing layer.

Flat roof condensation solutions.

Condensation isn t good news for a flat roof. Traditionally we ve insulated the roof panel to try and keep the temperature on the panel from reaching the dew point. This is especially so if it occurs within the roof s structure itself as this can lead to decay in the roof timbers which is very difficult to spot. It s designed to last decades but with problems like roof condensation moisture damage can dramatically cut even the best roof s lifetime short.

For example you can introduce vents by replacing some of the roof tiles. Insulate and try to keep from reaching the dew point. Be vigilant about your roof. By inspecting your roof for signs of condensation and acting on implementing solutions to resolve it you ll save yourself the.

Reroofing how to prevent roof condensation. These membranes usually made of polyethylene keep some water vapor from passing through. Vapor retarders are the true heroes here. For clarity flat roofs actually have a slight slope to allow rain water to drain off the roof but they seem flat when compared with more traditional steeply sloped roofs.

However vapor barriers a k a. Simply adding more holes on the surface of the roof or the use of roof vent tiles can make a huge difference in as far as improving the loft ventilation is concerned. The real key to avoiding moisture and condensation problems in low slope and flat roofs though is to keep moisture out of the ceiling in the first place. The slope should be a minimum of 1 in 80 but in practice a minimum slope of 1 to 40 should be used to allow for deflection of the roof and for normal building tolerances.

If you get to it in time your tin roof should still be viable for you to use. Add a preinstalled membrane to absorb and release the condensation as it forms with the natural weather cycle. When your roof is already in place there is unfortunately no direct or easy solution to the problem of condensation. Condensation is never good news for a flat roof.

Climb on the ladder and use your hammer and crowbar to remove the tin roof from the wooden frame. Insulation also helps diminish condensation issues. It can also reduce thermal insulation performance which can be a particular problem during winter. This includes defects in the roof membrane leaks at penetrations at parapet walls and at any other flashings on flat and low slope roofs.
