Maintaining A PVC Roof

Posted on

When your commercial building needs a flat roof, one of the options that you have available is a PVC roof. This material is chosen because it has the potential to be one of the longest-lasting roofs. To maximize the longevity of your roof, you will need to maintain it properly. The best time to have the PVC roof inspected is during the fall.

Only Perform Roof Maintenance During Warm Weather

When you perform maintenance on your roof, make sure that the temperature outside is at least 50 degrees or higher. When working on a PVC roof under cold weather conditions, the roof is more likely to crack.

Have the Roof Inspected After a Storm

Besides inspecting the roof annually, you will also want to have your roof inspected after major storms. This is when the roof will most likely have suffered damage that will need to be repaired. The main area that should be inspected is around the flashings. This is where the majority of the damage occurs on flat roofs.

Hire a Roof Inspector

Commercial roofing inspectors will be able to identify the parts of the roof that are weathering prematurely. This will allow the inspector to determine why these portions of the roof are weathering so early, so that steps can be taken to correct the problem. The inspection will also reveal if the PVC roof needs a roof cleaning and also needs debris to be removed.

Repair the PVC Roof if It is Shrinking

One common problem found with PVC roofs is that they are prone to shrinking. The process of shrinking can cause the seams to separate and can jeopardize the integrity of the roof. When this occurs, the roof can then experience leaks. For the areas where you see leaks, mark these areas with duct tape. This marking will show up easily even on a very dark roof. Then, you should clean the roof with a cleaning solution so that you can then apply a maintenance patching solution.

After you have cleaned the area where the seams have separated, add splice cleaner. Then, you will need to apply a sealant to the areas that shrunk. Another option is to seal the area using roof tape.

Secure Nails and Screws

The PVC roof will most likely have some nails or screws that were used to secure the roof into place. Some of these might be loose and could compromise the roof. Therefore, you will need to tap them back down into place. Then, your roof will be more likely to last longer and will save you more money in the long-term.
