Snow and ice sat on roofs for days, melted by day where attic heat reached the deck, and refroze at the cold eaves overnight. That builds ice dams, ridges of ice that back water up under the shingles, and across Lewisville and the rest of Denton County homeowners found leaks in places that had never leaked in a rainstorm.
It may be years before another storm like that, but the fixes are cheap to build in while a roof is being replaced:
The rest of the year, Lewisville's roofs face the usual North Texas threats. Neighborhoods near Lewisville Lake catch wind across the open water, and spring hail tracks through Denton County most years. Many Lewisville houses date from the 1980s and 1990s and are due for their second roof, so storm damage and old age often arrive together.

Most likely ice dams. Ice at the cold eaves trapped meltwater, which backed up under the shingles. Waterproof underlayment at the eaves and good attic insulation help prevent it.
At the eaves and in the valleys it is inexpensive insurance against the rare ice storm and wind-driven rain.
Granules in the gutters, curling or cracked shingles, repeated leaks, and a roof age past about twenty years are common signs. An inspection confirms it.
No. Ask for a certificate of insurance and local references.
