TER Exteriors | Roofing Services in Maryville, IL 62062

Maryville's heavy rains and freeze-thaw cycles put immense stress on roof valleys, where two roof planes meet. Leaks here are common due to worn underlayment or improper installation. TER Exteriors addresses this by first conducting a thorough inspection to find the exact source. We then clear debris, replace damaged materials with high-quality, ice-and-water shield products, and ensure proper overlapping and sealing to create a durable, watertight channel that directs water safely off your roof.

Local factors like humidity, temperature swings, and proximity to industrial areas can accelerate the corrosion of metal flashing around chimneys, vents, and walls. Corroded flashing loses its ability to seal gaps, leading to leaks. Our repair process involves carefully removing the old, corroded flashing, preparing the surface, and installing new, corrosion-resistant flashing (often aluminum or galvanized steel). We secure and seal it with professional-grade sealants to restore a tight, long-lasting barrier against the elements.

Early signs inside your home include water stains on ceilings or walls that run along the line of a roof valley or appear near a chimney or vent. Outside, look for missing granules in the valley, visible rust on flashing, or water not flowing cleanly into the gutters during rain. If you notice any of these signs, it's time for a professional assessment. TER Exteriors offers free, no-obligation inspections to identify these common local issues early, saving you from more extensive and costly repairs down the line.
