DIY can be rewarding, and many owners handle basic maintenance well. But some DIY repairs turn a small problem into a big bill. These are the ones we see most.
Sealant over sealant
Adding new sealant over old, dirty or cracked sealant can trap moisture and hide a leak that keeps spreading. Pros remove failed sealant, clean the surface and use the right product for the roof type.
Guessing at electrical faults
Swapping parts without testing wastes money and can create shorts. Pros diagnose with meters and load tests.
LP gas work
Gas leaks are a safety hazard. Pros leak-test and pressure-test after any work.
Overtightening and wrong parts
Stripped fittings, cracked plastic and the wrong replacement parts cause new failures.
Skipping the root cause
Fixing the stain without finding the leak, or replacing a tire without checking alignment and bearings, means the problem comes back.
When to call
