Hey, hey, hey! What do you say, folks? Today, I’m taking you along for a commercial roof inspections on a single-ply roof. It’s a 250-300 square foot PVC roof, a bit different from the usual TPO roofs we often see here in Houston. Let me show you around and walk you through the process I follow during these inspections.
Starting with the Perimeter Walk
One of the first things I do, and have been doing for the past 16 years, is walk around the perimeter of the roof. This step is crucial for several reasons:
- Assessing the Lay of the Land: Walking the perimeter gives me a good overview of the roof’s layout and any potential trouble spots.
- Checking for Wind Uplift: The roof edges are often where wind uplift damage occurs during storms. By inspecting these areas closely, I can identify and address issues before they become major problems. AKA….early roof leak detection.
- Roof Leak Detection: Before the inspection takes place, we normally get shown the leak areas. We always mark the anomalie areas on a map and definitely inspect those areas to see whats going on.
No matter the size of the roof, whether it’s as big as 10 football fields or as small as a single shop, this step is non-negotiable. After completing the perimeter walk, I always check in with the customer to identify any known leak areas.
Identifying Leak Areas with Precision
Using a Google Earth map, I mark the leak areas provided by the customer. This allows me to pinpoint these spots accurately once I’m on the roof. For example, if there are vent stacks nearby, I can use them as reference points to locate the leaks more easily.
During this inspection, I noticed several impact spots, possibly from hail or other sources, causing leaks. While the roof didn’t have any leaks initially, previous inspections revealed multiple issues that need addressing. This particular roof for its size only had a small area of roof ponding water issues.
Documenting Inspection Findings
Throughout the inspection, I take photos, especially at the corners, to document the condition of the roof. These overview pictures are invaluable for reference, especially when preparing detailed quotes for your Houston Roof repair.
Here’s what I found during this inspection:
- Ponding Water: There were a few areas with ponding water, a common issue that needs monitoring.
- Impact Spots: Several impact marks that might have been caused by hail or other objects.
These findings, combined with the photos, help create a comprehensive report for the property owner.
Comparing TPO and PVC Roofing
While TPO roofs are more common in Houston, PVC roofs have their advantages. In my experience, PVC welds better because you can see the material smoking during the process, ensuring a strong bond. However, both materials have their pros and cons.
For example, here’s a recent comparison I noted:
- PVC: Easier to teach new workers to weld due to visible smoke during welding.
- TPO: Preferred for inventory consistency as we mostly stock TPO materials.
Maintenance Tips for Longevity
Regular maintenance is key to extending the life of any roof. For this PVC roof, I recommend the following:
- Annual Inspections: Regular check-ups can prevent minor issues from becoming major repairs.
- WD-40 for Whirly Birds: Keeping these vents moving smoothly is essential, especially in commercial settings where they play a critical role in ventilation.
- Silicone Roof Restoration: Given the impacts and general wear, a silicone roof restoration could be a great option to extend the roof’s life.
Wrapping Up the Commercial Roof Inspections
After completing the perimeter inspection and documenting the findings, I turn my attention to the mechanical aspects of the roof. This roof had several pipe penetrations and whirly birds, all of which were functioning well.
One thing to note: I’m not a fan of peel-and-stick repairs. They don’t hold up as well as other methods, like using elastomeric coatings, which offer better adhesion and longevity.When to Repair vs Replace
