Roof restoration for community buildings such as condominiums or retirement homes is something Alliance Group is no stranger to. As with any commercial roof coating job involving occupied buildings, the goal is to complete the work in a time efficient manner while providing a safe environment for all crew members and building users. When it comes to condominium buildings, property managers, and owners don’t want to disturb tenants with an intensive project like roof replacement. Of course, worse is allowing a roof leak problem to manifest itself into bigger problems such as interior leaks, mold, and even structural building damage. This is why it’s important to have a roof inspection done. Commercial flat roof inspections will detect damage and moisture within the roofing system with tools such as moisture meters and by removing core samples.
With this procedure in place, a roofing professional can provide you with an accurate quote and plan of action on the work needed. See our video below for an overview of our roof coating project in Melbourne, Florida.
Visible Signs of Roof Coating Damage
The flat roof in the video above had a saturated layer of foam. If allowed on the roof for long enough, this would have cause water damage to the subsequent building materials. Water soaked foam also contributes to unnecessary weight to the building as a whole. In a severe case, this unnecessary added weight could cause support systems to fail and ultimately collapse.
So how does the insulation layer of a roof become soaked with water? In this case, the layer of acrylic coating sitting on top of the foam did not last and allowed water to seep through. The age of the roof may have also been a factor. See the visible signs of this in the photograph below. Notice there are blisters, large and small, throughout the entire roof. The center of the roof was recently covered by an acrylic coating. This was an attempt to stop water seepage, but unfortunately, the damage was done. To make certain of the roofing situation before proceeding with a job estimate, we use a moisture meter and core samples taken from multiple areas.
How Silicone is Superior to Acrylic Coatings
Over the decades, roof coating product formulas have improved. Alliance Group preferres to use silicone based formulas over acrylic due to their performance in the long term.
The main weaknesses of acrylic based coatings are how they weather and how they stand up to ponding water. Over time with sun exposure, wind and storms, a roof coated with acrylic will lose millimeters in thickness. It may not sound like much is lost, but a few millimeters would make a big difference it how well a coating layer will protect your roof. Small impressions or low areas in a roof are common. Unfortunately, this means they can harbor water puddles. The presence of constant ponding water over an acrylic coating layer will ultimately lead to its demise.
Acrylic’s weaknesses are silicone’s strength. Silicone is tougher against weathering. Due to its flexibility, it does not become brittle and crack under sun exposure. It also remains stable under ponding water.
