HEP’s certified team equips every visit with precision moisture meters, tracing dampness all the way to its source before it stains your ceiling or warps your rafters. Our detailed roof inspections combine hands-on know-how with digital readings, giving Sale Creek homeowners clear, data-backed answers instead of guesswork.
From historic farmhouses to modern lakefront builds, we tailor each report to your roof’s age, material, and exposure. You’ll receive side-by-side photos, easy-to-read moisture graphs, and a prioritized action plan—so you can decide whether you need a quick repair or a full replacement.

FAQs
Why are moisture-meter readings important during a roof inspection in Sale Creek?
Sale Creek’s proximity to Chickamauga Lake and the Tennessee River keeps relative humidity high for much of the year. This added moisture can accumulate beneath shingles, in decking, or around roof penetrations without showing visible leaks inside the home. A calibrated moisture meter allows our inspectors to detect elevated moisture content (typically anything above 15-18 % in wood) before rot, mold, or structural damage begins. Early detection means smaller repairs, lower costs, and a longer-lasting roof.
What kinds of moisture meters do you use, and how do they work?
We carry both non-invasive (capacitive) and invasive (pin-type) meters. Non-invasive meters send a low-frequency signal about ¾-inch into the material and return a reading in seconds without penetrating the surface—great for shingles, membranes, and ceiling drywall. Pin-type meters use two insulated pins that are inserted into the decking or framing to measure electrical resistance; the higher the resistance, the drier the material. We start with the non-invasive meter to map out anomalies and then confirm suspicious areas with a pin-type meter for precise percentage readings.
Will the moisture-meter testing damage my roof or shingles?
The non-invasive meter leaves no trace at all. When we need a pin-type reading, the pins are about the diameter of sewing-needle tips and only penetrate 1⁄4–1⁄2 inch. These tiny holes are in the roof decking under the shingle tab, so they are sealed when the shingle is relaid. The process is accepted by roofing manufacturers and will not void warranties or compromise the roof’s watertight integrity.
How can hidden moisture affect my Sale Creek home if it isn’t addressed?
Moisture trapped in OSB or plywood decking can lead to delamination and sagging, making the roof surface uneven and shortening shingle life. Prolonged dampness encourages mold growth, which can spread to attic insulation and indoor air. In our warm Tennessee summers, moisture plus heat accelerates wood rot, potentially requiring full deck replacement. Addressing problems when moisture content is still in the 18-25 % range usually limits repairs to selective shingle or flashing replacement instead of major structural work.
How often should I schedule a roof moisture inspection in this climate?
For asphalt-shingle roofs less than 10 years old, we suggest a moisture-meter inspection every two years or after any severe weather event such as hail, straight-line winds, or a tropical-system rainband. Older roofs (10+ years) or metal roofs with complex flashing details benefit from annual checks. Regular monitoring is especially important in Sale Creek because seasonal humidity swings and frequent summer thunderstorms can introduce moisture even without literal roof leaks.
What happens if your inspection reveals elevated moisture levels?
We document all readings on a moisture map, photograph affected areas, and explain the likely moisture source—whether it’s failed flashing, poor attic ventilation, or storm damage. Depending on severity we’ll recommend spot repairs, shingle replacement, improved ventilation, or in extreme cases partial deck replacement. You receive a written estimate and step-by-step plan, and we can coordinate directly with insurance if storm damage is involved. Our goal is to remove the moisture source, dry the decking, and restore the roof to full performance while keeping costs transparent.
