Considerations Before Installing Asphalt Shingles in Missouri
If you’re planning a new roof installation in Missouri, asphalt shingles are a popular and cost-effective choice. However, before moving forward, it’s important to consider key factors before asphalt shingle installation to ensure your roof withstands Missouri’s unpredictable weather, from heavy storms and high winds to hot, humid summers.
At One Way Roofing LLC, we specialize in high-quality Asphalt Shingle Roof Installation designed for Missouri’s climate. In this guide, we’ll explore the ten most important factors every homeowner should evaluate before installing a new asphalt shingle roof.
1. Missouri’s Climate and Weather Conditions
The weather in Missouri is a major factor in roofing durability. With hot summers, severe storms, and occasional ice storms in winter, your shingles need to be resilient and weather-resistant.
- High Temperatures and UV Exposure: Choose UV-resistant shingles to prevent fading and deterioration.
- Strong Storms and Wind Resistance: Opt for impact-resistant shingles rated for high winds, especially in storm-prone areas.
- Winter Ice and Snow: Proper attic ventilation and ice barriers help prevent ice dams and water damage.
In areas like St. Louis County and St. Charles County, we recommend installing shingles with a Class 4 impact resistance rating to protect against hail damage.
2. Roof Slope and Drainage Considerations
Your roof’s pitch (slope) affects the type of asphalt shingles you need.
- Low-Slope Roofs: Require additional waterproofing layers to prevent leaks.
- Steep-Slope Roofs: Allow water to drain easily but may require specialized installation techniques.
A professional roofing assessment will determine the best shingle type for your home’s structure.
3. Local Building Codes and Permit Requirements
Missouri, including St. Louis and St. Charles counties, has specific roofing regulations that homeowners must follow.
- Fire Ratings: Some areas require fire-resistant roofing materials.
- Wind Resistance Codes: Roofs must meet wind uplift standards, especially in storm-prone regions.
- Permit Requirements: A roofing permit may be needed, depending on your location.
At One Way Roofing LLC, we ensure full compliance with Missouri’s roofing codes and help homeowners navigate permit requirements.
4. Choosing the Right Asphalt Shingles
Not all shingles are the same. Consider these types.
- 3-Tab Shingles: Affordable but less durable, lasting 15 to 20 years.
- Architectural Shingles: More durable with better weather resistance, lasting 30 years or more.
- Luxury Shingles: High-end appearance with maximum durability, mimicking slate or wood.
In Missouri, architectural shingles are ideal for handling storm damage, temperature fluctuations, and high humidity.
5. Proper Underlayment and Ventilation
Quality underlayment and proper ventilation ensure a long-lasting, energy-efficient roof.
- Underlayment: Adds a waterproof barrier to prevent leaks.
- Ventilation: Reduces moisture buildup, preventing mold and premature shingle wear.
Missouri summers can reach over 90 degrees Fahrenheit, making attic ventilation critical for cooling efficiency and preventing shingle overheating.
6. Hiring a Professional Roofing Contractor
Choosing an experienced, licensed, and insured roofing contractor is essential for a long-lasting installation.
At One Way Roofing LLC, we provide:
- Certified installations backed by warranties
- Local knowledge of Missouri’s unique roofing challenges
- Reliable service with a focus on durability and quality
Avoid out-of-state contractors who offer cheap roofing services but disappear after installation.
7. Budgeting for Asphalt Shingle Roof Installation
While asphalt shingles are affordable, costs depend on several factors.
- Shingle Type: Architectural shingles cost more but last longer.
- Roof Size and Complexity: A larger, steeper roof requires more labor and materials.
- Additional Features: Flashing, ventilation, and waterproofing impact the total cost.
We offer free estimates and financing options for homeowners in Missouri.
8. Tear-Off vs. Overlay for Asphalt Shingle Roof Installation
- Tear-Off: Completely remove old shingles before installing new ones for better longevity.
- Overlay: Adds new shingles over existing ones, which is cheaper but may reduce durability.
Many counties, including St. Louis County, limit overlay roofing due to structural weight concerns.
9. Energy Efficiency and Eco-Friendly Options
Energy-efficient shingles reduce cooling costs and improve sustainability. Look for the following features.
- Cool Roof Technology: Reflects heat to reduce AC use.
- Recyclable Shingles: Choose brands that recycle old shingles into new materials.
- Energy Star Rated Products: Improve home insulation and reduce energy bills.
Missouri summers can cause high energy bills, and energy-efficient shingles help cut cooling costs by up to 25 percent.
10. Best Time of Year for Asphalt Shingle Roof Installation
Timing affects both cost and quality.
- Spring and Summer: Ideal weather but higher demand, which may mean longer wait times.
- Fall: A perfect balance of good weather and contractor availability.
- Winter: Installation is possible but requires specialized techniques for cold temperatures.
Many homeowners in Missouri book roofing projects in late summer or early fall to avoid storm season delays.
