Leak Detection & Roof Repair in Mesa, AZ

Fast, Accurate Leak Detection & Long-Lasting Roof Repairs

Precision Leak Detection for Arizona Homes & Buildings

Most roof leaks start small—hidden beneath shingles, flashing, tiles, or flat roof coatings—and spread silently through insulation, drywall, and framing. That’s why we use advanced moisture-tracing and thermal inspection tools to detect hidden water intrusion before visible damage occurs. Whether it's a valley leak, skylight flashing issue, or roof deck puncture from monsoon debris, we pinpoint the exact cause and tailor the repair to match your roofing system.

Water Stains on Ceilings or Walls

If you see dark rings or yellowish-brown spots on your ceiling or upper walls, it’s a classic sign of a roof leak in progress. These stains often appear long before dripping begins and typically indicate that water is pooling above your ceiling drywall or seeping down wall cavities. In Mesa, this is common after monsoon storms, where roof underlayment or flashing may fail. At JJ Roofing Group, we track these stains back to their source using advanced moisture detection tools and provide fast, permanent repairs before mold or structural damage sets in.

Peeling Interior Paint or Bubbling Drywall

Paint that’s flaking, cracking, or bubbling on interior surfaces is often a symptom of hidden water intrusion. When moisture seeps through the ceiling or walls, it causes the paint or drywall texture to lift or bubble, especially around seams and corners. This kind of damage is more than cosmetic—it’s a red flag for roof leaks or attic humidity issues. Our Mesa roofing specialists check both roof and insulation layers to diagnose where the leak started and restore the materials to safe, dry condition.

Missing or Damaged Shingles or Tiles

Visible damage on your roof—such as cracked shingles, slipped tiles, or granule loss—is one of the most obvious signs that your roofing system is compromised. In Mesa, shingles can easily crack from thermal shock, and tiles may shift after high winds or foot traffic. Even small gaps allow water into your roofing system, especially around vents, chimneys, and valleys. JJ Roofing Group offers

free visual inspections to identify missing or worn components and replace them before they lead to interior leaks.

Warped Wood or Sagging Insulation

If your ceiling feels soft, your attic wood is bowed, or your insulation is compressed and damp, your roof leak has likely been active for some time. Wet framing loses strength, and soggy insulation loses its R-value—both of which increase energy bills and pose serious long-term damage risks. We assess these hidden signs of roof failure and offer full moisture barrier repair, insulation replacement, and roof deck restoration where needed.

Home emergencies are inherently overwhelming and all consuming. Often times you really aren't sure where to start and who to trust. After starting with a few other companies I opted to give Jonnel and Jacob a shot...I am glad I did.

-Daniel D.

We tried getting our roof done awhile ago. Insurance was a no go. Recently, we met Jonnel and Jacob, they were awesome. We got approved to get our roof done. Although, there were many speed bumps with the insurance throughout the whole process, these guys kept by our side.

-Shannon S.

Quality roofing in a timely manor was promised and these guys made it happen! I can’t believe how nice the roof looks and the color is gorgeous (hickory color). The entire process was super smooth and the roofing crew were very informative throughout the entire process.
