Rust treatment should be part of a regular roof maintenance program.

If left untreated the rust can destroy a metal roofing system. The rust will create damage to the structural integrity of the metal roof panels. For best practices rust should be treated when it first appears prior to its spreading. It can be important to determine the main cause of the rust. For example: if caused by galvanic corrosion, remove the questionable corrosive metal and replace it with a similar metal to the substrate.

Before applying a rust inhibitor the surface must be thoroughly cleaned to promote proper adhesion. Then the surface must be dried, before applying a surface seal. Then the roof should be treated for rust. Heavy rust may require a second application of rust inhibitor material.

Roof recovering is roofing over an existing membrane. This requires that special considerations be taken.

• Check for moisture: trapped moisture may cause blisters, damage insulation and, in some cases affect the structural integrity of the deck.
• Check structural load capacity: make sure that the existing roof can withstand the additional weight of a new roof assembly.
• Remove walkway pads and all wood blocking: do not roof over wood blocking and walkway pads. Make sure that the existing roof provides a smooth substrate for the new roof.
• Remove gravel surface: remove all gravel surface with a power broom or vacuum to ensure a smooth surface.
• Remove and replace wet materials: these can affect the performance of the roof system.
• Remove coatings: this can be done with a power washer.
• Remove old flashings

Repair blisters and ridges to achieve a flat substrate. Then make sure the roof surface is free of all dirt and debris.

The demand for roofing materials is currently weak. The building materials market has been hurt by the continuous softness of the U.S. housing market. Many including Owens Corning do not expect weakness in the roofing business to improve during the remainder of the year.

Owens Corning’s (NYSE:OC) third-quarter earnings fell 65%, amid steep declines in demand for roofing materials. Owens Corning reported a profit of $44 million, or 37 cents a share, down sharply from $124 million, or $1.01 a share, a year earlier.

The company has officially reduced its 2012 earnings outlook and cut its expectations. As well as other well respected companies in the roofing industry today.
