Solar Panels in McKinney: Start With the Roof

NOAA's Storm Prediction Center logged 59 hail reports of 1.75 inches or larger within 10 miles of McKinney from 2015 through 2024. Large hail can crack panel glass and damage frames, and it damages the shingles around the mounts too. A roof that already has storm damage should be fixed before anything is bolted to it.

Half of the homes in McKinney were built before 2007 (U.S. Census Bureau, American Community Survey 2020-2024). A roof near the end of its life is a poor base for panels. Replacing it later means taking the panels off and putting them back, which is extra work you can avoid with planning.

Hail does not stop at the panels. The shingles between rows and at the edges of the array take hits as well, and they are harder to inspect once the panels are on. Starting with a sound roof makes later checks simpler.

If your roof needs replacing before solar, think about how the new roof will hold up under the array. Impact-rated shingles tested under UL 2218 and rated Class 4 resist hail better than standard ones. Metal and stone-coated roofs also handle storms well. Our article on asphalt shingles vs. metal roofing in Texas compares the options.

Whatever you choose, plan the roof and the panels as one project. That way the flashing at each mount is part of the new roof, not something added on top later.

Solar is a long commitment for the roof. The best time to plan it is before a storm forces the question. If you already know the roof is aging, ask for a quote on both together so you can see the full picture. Financing is available for the roofing work, and estimates are free.
