Why Choose Asphalt Shingles for Re roofing?
When evaluating roofing materials, asphalt shingles stand out for several reasons:
Asphalt shingles come in a broad array of styles, textures, and colours, making it easy to find a design that complements your home's architecture. Whether you have a contemporary build or a classic Victorian-style home, asphalt shingles can be tailored to suit your aesthetic preferences.
2. Exceptional Durability
Designed to withstand severe weather conditions, asphalt shingles are resistant to rain, snow, and high winds. Some high-performance shingles are even rated to endure winds of up to 130 mph, making them an excellent choice for areas prone to storms or hurricanes.
3. Budget-Friendly Option
Compared to materials like metal, slate, or tile, asphalt shingles are significantly more affordable. Their combination of lower upfront costs and relatively easy installation makes them a popular option for homeowners seeking value without compromising quality.
Modern asphalt shingles, particularly those with cool roofing technology, reflect more sunlight, reducing heat absorption. This can lead to lower cooling costs, especially during the summer months.
Types of Asphalt Shingles
Understanding the different types of asphalt shingles will help you make the right choice for your home:
3-Tab Shingles: These are the most economical option, characterised by their flat, uniform appearance. While they are lightweight and easy to install, they have a shorter lifespan compared to other types, typically lasting 20–25 years.
Architectural (Dimensional) Shingles: These offer a more robust construction and a multi-dimensional appearance, resembling wood shakes or slate. They are more durable than 3-tab shingles, with a lifespan of 30–50 years.
Luxury Shingles: Designed for homeowners seeking premium aesthetics, these shingles mimic the look of expensive materials like natural slate or cedar shakes. They are heavier and more durable, making them an excellent choice for high-end projects.
Key Considerations Before Re roofing
Re roofing involves more than simply replacing old shingles. Here are some factors to keep in mind:
1. Inspecting the Existing Roof
Before proceeding, it's essential to inspect the condition of your existing roof. Issues such as rot, water damage, or structural weaknesses need to be addressed to ensure a stable foundation for the new shingles.
2. Layering vs. Full Replacement
In some cases, new shingles can be installed over existing layers, saving time and money. However, if the current roof has significant damage or already has multiple layers, a full replacement may be necessary.
Your local regulations may limit the number of shingle layers allowed on a roof or require specific installation standards. Check with your municipality to ensure compliance.
4. Choosing the Right Underlayment
The underlayment, installed between the roof deck and shingles, is crucial for waterproofing and protecting your home from moisture infiltration. Options include felt paper and synthetic materials, each with varying levels of durability and cost.
Proper ventilation extends the life of your shingles by preventing heat and moisture buildup in the attic. Ensure your contractor addresses ventilation during installation.
The Installation Process: Step by Step
Re roofing with asphalt shingles follows a detailed process to ensure durability and reliability:
1. Preparation and Removal
The old roofing material is removed, and the deck is inspected for damage. Necessary repairs are made to create a solid foundation.
2. Underlayment Installation
The underlayment is applied to provide additional protection against water infiltration.
Shingles are installed starting at the roof's lower edge, overlapping to create a watertight seal. Careful alignment ensures a uniform appearance.
Critical areas, such as chimneys, vents, and skylights, are sealed with metal flashing to prevent leaks.
The completed roof is inspected to ensure all components are securely installed and meet quality standards.
Maintenance Tips for Longevity
A well-maintained roof can last for decades. Here’s how to keep your asphalt shingles in top condition:
Conduct biannual roof inspections, as well as after severe weather events. Look for loose, curled, or missing shingles, and address issues promptly.
Clogged gutters can cause water to back up onto the roof, leading to damage. Clean them regularly to ensure proper drainage.
3. Address Moss and Algae Growth
In damp climates, moss and algae can develop on shingles, causing discolouration and deterioration. Use a gentle cleaning solution or hire a professional to remove growth safely.
4. Trim Overhanging Branches
Nearby trees can drop leaves and branches onto the roof, potentially causing damage. Keep branches trimmed back to prevent issues.
The cost of re roofing with asphalt shingles varies depending on factors such as shingle type, roof size, and labour charges. On average, homeowners can expect to spend:
3-Tab Shingles: $2,500–$8,000 for a typical roof.
Architectural Shingles: $5,000–$15,000 for a higher-end installation.
Luxury Shingles: $10,000–$25,000 or more for premium designs.

Environmental Considerations
If sustainability is a priority, you’ll be glad to know that asphalt shingles are recyclable. Many recycling programs turn old shingles into paving materials, reducing waste in landfills.

Positive reviews and referrals.
