When it comes to residential roof repair or replacement, most homeowners focus on shingles but what’s underneath matters just as much. The roof underlayment acts as the unsung hero, providing a critical layer of protection between your roof deck and the shingles. Choosing the right underlayment can significantly extend your roof’s lifespan and improve performance.

Here are the main types of roof underlayment to consider:

1. Asphalt-Saturated Felt (Traditional Option)
A time-tested choice, this underlayment provides decent water resistance and breathability. It’s affordable but less durable than modern alternatives.

2. Synthetic Underlayment (Modern Standard)
Made from polyethylene or polypropylene, synthetic underlayment is stronger, lighter, and more resistant to tears, moisture, and UV damage, a smart choice for Houston’s hot, humid climate.

3. Rubberized Asphalt (Premium Protection)
For maximum waterproofing, rubberized asphalt is ideal. It offers superior adhesion and flexibility, making it perfect for vulnerable roof areas like valleys or low slopes.

Proper underlayment installation during roof repairs ensures better insulation, weather resistance, and long-term performance. At Houston Roofing & Gutters, we use top-grade materials and expert craftsmanship to keep your home protected and comfortable for years.
