See below for a diagram of some of the most common roof repairs to extend the life of your roof.


Holes and punctures in the roof membrane occur when there is debris on the roof. Everything from foot traffic to local wildlife can leave scrapes, puncture marks, or even big holes in a roof. These types of roof defects can be repaired by patching the existing holes and punctures with new membrane and either heat welding or fully adhering membrane with bonding adhesive.


Open seams arise when the roofing system begins to age or a result of poor initial roof installation. It's very important to choose a trustworthy contractor when repairing your commercial roof to avoid any extra costs to repair or replace your new roof. These roof deficiencies can be repaired by heat welding or fully adhering membrane to patch the open seams.


Water that ponds or stands on your roof is an issue to be addressed. Common cause range from debris buildup to improper drainage of HVAC units and gutters. The simple repair for ponding water is to remove existing debris from the roof and unclog the drains. If the ponding water is substantial, there may be further damage that will need more attention.


Clogged drain, downspouts and gutters are a result of an excess of debris on the roof that enters the roof drainage systems and causes the system to be backed up with water and debris. Our roof repair professionals can unclog the downspouts, gutters and roof drains and remove any additional debris from the roof so that the drainage system performs to the highest standards.


Bridging walls on the roof are usually a sign that the roof is beginning to age out and nearing time for a roof replacement or the initial installation of the roof was not performed properly. The defect can be repaired by cutting the base of the bridging wall to allow the membrane to relax and then install new reinforced perimeter strip (RPS).


Overtime fasteners have a tendency to back out of their seated position. This can be for various reasons. Most of the time this happens when water gets in the roof membrane and increases the rate at which the roof expands and contracts which causes the fasteners in the membrane to slowly be pushed out. In order to repair fasteners that have been backed out, they need to be completely removed so the insulation and membrane can be checked for water damaged and install new if necessary before re-installing the fasteners.


This is a very common roof defect that occurs when the roofing system begins to age. These repairs are some the most common on flat commercial roofs and can be repaired by cutting out deteriorated caulking and installing new sealant. Our experienced professionals are skilled at identifying declining caulking and removing it without adversely affecting the membrane.


Over time, roofs can develop cracks, blisters, and ridges. Built-up roofs are roofs made of several layers that cover a relatively flat surface, are particularly susceptible to cracking and blistering. In order to repair roof blisters, the blistered membrane needs to be cut to relieve tension and then a new modified cap sheet is torched down to patch the area where the membrane was cut.
