How to Maintain a Thermoplastic Polyolefin Roofing System
You already know that neglecting a TPO roof can lead to big problems, including structural damage. So, here are the steps for maintaining this popular single-ply roofing membrane.
Make sure the roof drains properly.
Drainage problems are common on flat roof systems. It’s a simple matter of physics: flat roofs don’t drain as well as pitched roofs. The low pitch makes it easy for water to pool on the surface and for dirt to accumulate. Pooled water can also break down the roofing material, which leads to destructive leaks.
So, gutter and drainage system maintenance is an essential part of roof maintenance.
Remove debris from the roof surface.
Even though TPO membranes are strong, TPO is still a single-ply roofing system that must be protected from puncture or tears. That’s why removing overhanging trees is crucial so that branches don’t litter your roof deck.
To maintain your TPO system, you should periodically look for and remove debris from the roof surface.
Clean your TPO roof according to the manufacturer’s guidelines.
TPO roofs require regular cleaning. It’s important to remove dirt, mold, and algae from the surface of low-slope roofs for two reasons.
Dirt and debris on the roof surface may break down the membrane and cause damage.
Also, light-colored TPO roofs reflect UV rays, making the building more energy efficient during the summer. If the white surface is covered with dirt, you will harm your building’s energy efficiency – AND decrease the lifespan of your roof.
Begin by protecting low curbs, base flashing, and other areas where the pressured water could infiltrate. Also, consider covering the vegetation around the building, as some cleaning solutions may harm trees and bushes.
Most manufacturers and installers recommend using a low-pressure power washer and mild cleaning solution to clean a TPO rooftop. You may also need a floor broom or a soft-bristle push broom. Take special care to rinse the cleaning solution from the roof and look for and repair any incidental damage.
Schedule regular, professional inspections with a roofing contractor.
Yes, there are things that your maintenance crews can do to maintain your TPO roof. However, it’s also essential that a certified roofing contractor periodically visits to inspect the condition of the roof membrane.
Besides looking for signs of ponding water or inadequate drains, a roof inspector will check for signs of deterioration in sealants and around coping joints, coping ends, and skylights. Even small holes and seemingly minor cracks in joints and seams can lead to severe damage, so they will be flagged for repair.
