September and October are good months to inspect your home’s roof or your commercial building before the rainy season hits.
You see a leak, get nervous, and wonder if you’re going to get hit with an expensive roof replacement expense.
If you’re a homeowner or commercial building owner in Arcadia, Monrovia or anywhere in the San Gabriel Valley, you might have a leak due to solar panels or other protrusions on your roof.
Signs of moisture in your attic or in the interior of your building don’t automatically mean that you need a new roof.
Let’s look at the reasons why you might be having a leaking roof.

Solar Panels and Leaky Roofs
Solar panels can cause leaks in your roof from being improperly mounted, having the sealant wear out over time due to extreme heat, and flashing not being installed correctly.
Leaks can develop around the lag bolts.
Older, asphalt shingles can be damaged by installers and this can lead to the summer heat degrading sealant that may have worked well the last several years. But if the sealant is cracking or has decayed then it can be time to re-apply and make sure the mounts are watertight.
A roof is supposed to shed water, but sometimes the solar panels stop the water flow.
Thomas Garvey has repaired and installed roofing in the San Gabriel Valley for over 35 years and has repaired and installed new roofs on all types of structures from historic homes to apartment complexes.
Solar panels are best installed on roofs that are no more than several years old.

Low Slope Commercial Roofing Repair
The next time you’re driving along the 210 freeway or the 605, glance at the commercial roofs with single ply membranes and imagine how much of the sun’s heat the roofs absorb.
Over time, seams can weaken due to the heat and cooler air causing expansion and contraction.
Membranes can tear from anyone who walks on the roof or if debris blows and punctures the materials.
Poor drainage causing ponding water is another reason low-slope commercial roofs can leak. A fix may mean reinstalling decking in a specific area of the roof.
Sealants around protrusions like HVAC systems can weaken in the summer sun and become vulnerable to leaks in the winter rains.
Garvey Roofing will do a thorough inspection of your roof and what it needs to remain healthy.
