FAQs
Why are high-performance sealants essential for roofs and siding in Signal Mountain?
Signal Mountain experiences intense UV exposure, frequent rain, and seasonal freeze–thaw cycles. High-performance elastomeric sealants flex with temperature changes, repel wind-driven moisture, and block UV degradation far better than traditional caulks. Using them prevents premature leaks, energy loss, and rot—extending the life of shingles, metal panels, fiber-cement siding, and trim in our local climate.
What kinds of sealants do you install and how do I know which one is right for my home?
We carry premium silicone, polyurethane, and silyl-terminated polyether (STPE) formulations. Each is chosen based on the substrate: • 100 % silicone for metal roofs, skylight curbs, and glass where maximum UV resistance is critical. • Polyurethane for fiber-cement or engineered-wood siding joints because it bonds strongly to porous surfaces and can be painted. • STPE hybrids for mixed-material projects (e.g., metal roof to masonry wall) because they adhere to almost anything and cure quickly in our humid conditions. During your consultation we inspect your roof/siding materials, joint widths, and movement requirements, then specify the most compatible product and color match.
How long will the sealant last and when should I schedule maintenance?
Properly installed high-performance sealants last 15–25 years on vertical siding joints and 10–20 years on horizontal roof seams, depending on exposure. We recommend a visual inspection every 3–5 years; early touch-ups are inexpensive and prevent costly water damage. Our team offers an optional maintenance plan with scheduled inspections and moisture-meter tests to catch issues early.
Can you apply sealant to my existing roof or siding, or is it only for new construction?
Both. For retrofits we remove failing caulk, clean the joint surfaces, perform minor substrate repairs, and prime where necessary before applying the new sealant. This rejuvenation approach is common on homes 5–20 years old that show minor leakage or energy loss. For new construction we integrate sealant application with flashing and underlayment installation to create a continuous weather-tight envelope from day one.
Will the sealant change the appearance of my roof or siding?
No. Our sealants are available in clear and over 300 color-matched options, including custom blends that align with major shingle, metal, and siding manufacturers’ palettes. Low-sheen finishes minimize glare, and paintable polyurethane allows an exact match to existing trim colors. Once cured, the joints are virtually invisible yet fully protected.
Are your sealants eco-friendly and safe for families and pets?
Yes. All products we use are VOC-compliant with Tennessee regulations and contain no phthalates or isocyanates. Curing releases only trace alcohols or COâ‚‚, so you can remain in your home during installation. The long service life reduces landfill waste from premature siding or roofing replacement, making high-performance sealants a sustainable choice for Signal Mountain homeowners.
