Solar Panels on a Mesquite Home: Roof First, Then Panels

Solar panels stay on a roof for many years. On an older Mesquite house, the roof needs to be ready to carry them that long.

The roof under the panels in Mesquite

Half of the homes in Mesquite were built before 1983 (U.S. Census Bureau, American Community Survey 2020-2024). Many have had a new roof since, but not all of those roofs are young now. Panels mounted on a roof with only a few years left will have to come off when it is replaced, and that adds work you can avoid.

Hail is part of the picture too. NOAA's Storm Prediction Center logged 49 hail reports within 10 miles of Mesquite from 2015 through 2024, and nine were 1.75 inches or larger. Large hail can damage panels and the roof around them. Fixing any existing storm damage before installation keeps the two problems from mixing later.

About 63% of Mesquite homes are owner occupied. Solar is a decision for the owner of the house, since it changes the roof and stays with the property.

What we check before mounting anything

Remaining roof life

Shingle wear, granule loss and past repairs.

Deck strength

Solid boards and rafters where the mounts will anchor.

Layers

Mounting through two layers of shingles is not ideal. A tear-off may be the better start.

Attic ventilation

Good airflow helps the roof under the array last.

1

Inspect

Start with a roof inspection in Mesquite so the plan rests on facts.

2

Prepare the roof

Repairs or a replacement come first when needed.

3

Mount and flash

Each mount is anchored and flashed so it sheds water like the rest of the roof.

4

Install panels

Panels go in, and the roof is checked again around the array.

Questions to ask any solar installer

Who is responsible if a mount leaks?

How are mounts sealed on my type of roof?

What happens if the roof needs work later?

Will someone check the roof before installation, not just the sun exposure?

Choosing a roof that will sit under panels

If the roof needs replacing before solar, choose it with the array in mind. The panels will cover part of it for many years, so a durable roof under them saves trouble later. Impact-rated shingles tested under UL 2218 and rated Class 4 resist hail better than standard ones. Metal and stone-coated roofs also hold up well, and each needs its own mounting method.

Plan the layout before the new roof goes on. When mount locations are known, flashing can be built into the new roof instead of added afterward. Our guide on how long roofing materials last in Texas compares the options, and asphalt shingles vs. metal roofing looks at two common choices side by side.

Frequently Asked Questions

How do I know if my roof is too old for solar?

If the roof is near the end of its life, has storm damage or has had several recent repairs, it is usually better to replace it first. An inspection checks shingle wear, decking and flashing and tells you how much life is left before you decide.

Do solar mounts cause leaks?

Any hole in a roof can leak if it is not sealed well. Properly flashed mounts shed water like a vent or pipe boot does. The installer's roofing skill matters as much as the panels. Ask how each mount will be sealed on your roof type.

Can I add panels to a roof with two layers of shingles?

It is possible in some cases, but it is not ideal. Mounts need to reach solid structure through both layers, and a later tear-off means removing the panels. Many owners choose to tear off and replace the roof before installing.
