Frequently Asked Questions

What are the signs of poor roof ventilation in my Merced home?

Common signs include excessive heat in your attic, unusually high summer cooling bills, ice dam formation in winter (though rarer here), and premature aging of your shingles, like curling or cracking. In the long term, trapped moisture can lead to mold and wood rot in your roof decking. Our team can perform an attic inspection to assess your ventilation and recommend solutions tailored to your home's design.

Why does roof flashing fail so often in our area, and how can Lunas Roofing fix it?

Flashing—the metal strips sealing joints on your roof—can fail due to Merced's temperature swings, high winds, and improper installation. Over time, this leads to leaks around chimneys, skylights, and roof valleys. We repair or replace failed flashing using durable, corrosion-resistant materials and meticulous sealing techniques. We also inspect the surrounding roof areas to ensure the underlying structure hasn't been compromised by water damage.

Can you repair a ventilation or flashing issue without a full roof replacement?

Absolutely. In many cases, targeted repairs are sufficient. We can install additional intake or exhaust vents to correct airflow or replace specific sections of damaged flashing. We always provide a thorough, honest assessment. If the overall roof is nearing the end of its life, we'll discuss your options, but our goal is to provide the most effective and cost-efficient solution to protect your home.
