EVERYTHING HOUSTON HOMEOWNERS SHOULD KNOW ABOUT THEIR ROOF
Your roof is one of the most important protective systems on your home. Understanding how it works and what causes failure can help you make informed decisions and avoid costly mistakes.
STORM DAMAGE IN HOUSTON
High winds, hail, and heavy rain can cause visible and hidden roof damage. Common signs include:
• Missing or lifted shingles
• Creased shingles
• Granule loss
• Damaged flashing
• Interior ceiling stains
Not all storm damage is obvious from the ground. A professional inspection helps determine the true condition of the roofing system.
ROOF VENTILATION MATTERS
Proper attic ventilation plays a major role in roof performance and shingle lifespan.
Poor ventilation can cause:
• Excess attic heat
• Premature shingle aging
• Moisture buildup
• Decking deterioration
• Warranty limitations
A balanced system typically includes both intake ventilation and exhaust ventilation to allow consistent airflow.

Improper ventilation can lead to premature aging, shingle distortion, and moisture damage inside the attic. Balanced intake and exhaust ventilation is critical for long term performance.
WHAT IS A MANUFACTURER WARRANTY?
Most shingle manufacturers offer material warranties that cover manufacturing defects.
Important to know:
• Warranties cover product defects, not installation errors
• Improper ventilation or installation may affect warranty coverage
