Flashing seams / missing nails

Flashing refers to the materials used in joints on the roof or walls of your home. Its job is to prevent water from seeping in and causing damage to the home’s walls and ceilings, causing structural damage to the home, or creating moisture and mold problems throughout the home.

On the roof flashing is found anywhere there is an elevation transitions in a roof line. This includes valleys, around chimneys and pipes, around dormers, and around any skylights or other structures that come up through the roof. Flashing is also commonly found beneath the first course of bricks on a home or chimney, above all wood trim around doors and windows, and where stairs and decks attach to the home.

Corrosion areas on metal surfaces

To better understand a corroding roof, let’s start with how metal roofs are actually made and the benefits of having a corrugated metal roof. Sheets of flat steel are fed from a roll onto a metal forming machine. The sheets are flattened, then formed and vary in size depending on the roof sheet specification. They are then cut to set lengths by guillotine and treated at each end. The cut ends or cut edges are a weak point that will require maintenance throughout the lifespan of the roof.

SPF roof air/moisture pockets

If you’re asking the question ‘What is Spray Polyurethane Foam Roofing’ you are likely new to commercial roofing or looking to replace/repair your roof.

Either way, we can help.

Spray Polyurethane Foam, more commonly referred to as SPF, is a material that is sprayed as a liquid so it can expand into a foam, creating a solid layer across an existing roof. While SPF roofing is not the most known type of roofing material, the technology has been around since the early 1960s for industrial, commercial, and residential facilities. An SPF roofing system can be used in any climate, and when properly installed and maintained, can last over 50 years.

Damaged surfaces

Puddles that have collected in various places is a symptom of an initial improper installation, and can lead to a leaky roof. Metal that appears to be rusty has corroded, telling you that in that area the roof has lost its protective sealant. If your flat roof has missing pieces of flashing and is also missing nails, this could be a sign of serious damage caused by prolonged exposure and strong winds. This can cause more problems involving a loss of protection in the future, and should be assessed as soon as possible before these common problems turn into a nightmare! With cracks, tears, and especially missing essential roofing pieces, leaks are bound to happen sooner than later.

Sometimes the damage that has occurred can leave you feeling indecisive and wondering what to do concerning your roofs condition. Repairing and maintaining can increase the lifespan of your roof, but if the roof has not been maintained properly, and the damage is well beyond normal, replacing the flat roof on your commercial building may be your best bet.
