replacing shingles on a roof with Naperville roofers

Many homeowners might be tempted to save time and money by opting for roofers who shingle over old shingles instead of doing a full roof replacement. This approach can seem appealing due to its lower initial cost and quicker completion time.

Layering new shingles over old ones can lead to underlying issues being missed, such as water damage or rot, which can compromise the integrity of the entire roof. Another concern is the added weight that multiple layers of shingles place on the roof structure, potentially leading to structural problems over time. Another issue that can happen is you can compromise your manufacturer’s warranty on your shingles by not having the proper roof components and installation process implemented per manufacturers’ recommendations and requirements. 

By choosing a full roof replacement, homeowners ensure that any hidden damage is addressed and the new shingles adhere properly to a fresh surface. This solution provides a longer-lasting, more reliable roof, offering peace of mind for years to come.

Understanding Roofing Fundamentals

Roofing systems are complex structures requiring precise installation and high-quality materials. Focusing on the vital components, types of shingles, and the necessity of ventilation and insulation helps ensure durability and effectiveness.

Components of a Roofing System

A properly built roof consists of several key components. The foundation is the decking, typically made of plywood or OSB (oriented strand board).

Underlayment or roofing felt, often made from asphalt-saturated materials, provides an additional layer of protection against moisture. Felt paper is another common choice.

Ridge vents and soffit vents are crucial for ventilation, preventing heat and moisture buildup. Insulation should also be appropriately included to maintain energy efficiency.

Types of Shingles and Materials

Different roofing materials cater to various needs. Asphalt shingles are the most popular due to their affordability and ease of installation. They come in various styles and colors, providing options for aesthetic preferences.

Metal roofing, known for its durability and long lifespan, is another common choice.

Other materials include wood shakes, clay tiles, and slate, each offering specific benefits such as natural insulation and unique appearances.

The Importance of Proper Ventilation and Insulation

Proper ventilation and insulation play crucial roles in any roofing system. Ridge vents along the roof peak allow hot air to escape, while soffit vents at the eaves enable cool air intake.

Additionally, adequate insulation reduces energy costs by maintaining interior temperatures. Preventing moisture accumulation in the roof’s structure helps avoid damage and prolongs the roof’s lifespan.

Why Full Replacement Matters

Full roof replacement ensures long-term durability and reveals hidden issues that layering new shingles over old ones can conceal. This approach aligns with building codes and prevents future costly repairs.

The Risks of Layering New Shingles Over Old

Layering new shingles over old shingles might seem cost-effective initially, but it can lead to significant problems. Weather, such as high winds, can easily lift poorly installed layers, causing leaks and damage. Hidden issues, like rotten plywood sheathing, remain undetected, leading to failures that a full replacement could prevent. Nails used in multiple layers might not fasten securely, causing the new shingles to loosen over time.

Inspection and Discovery of Hidden Issues

A complete tear-off allows a thorough inspection of the roof structure, revealing problems that might be hidden under existing shingles. Issues like water damage, holes, and rotting sheathing are visible and can be addressed properly. Ensuring flashing and starter strips are in good shape is pivotal to preventing leaks and extending the roof’s lifespan. Moreover, a full inspection uncovers poor installation practices and potential structural weaknesses.

Long-Term Benefits of a Full Tear-Off

While the cost of a full tear-off might be higher upfront, it is often more cost-effective in the long run. It ensures that only one layer of shingles is placed, enhancing the roof’s durability. New installations comply with building codes and integrate modern materials like ice and water shield and leak barriers, which protect against harsh weather conditions. Removing old shingles allows precise installation of roofing nails and flashing, resulting in a more stable and weather-resistant roof. The thorough approach prevents costly repairs and ensures the roof remains in good shape for years.

Choosing the Right Contractor

Selecting the proper roofing contractor can significantly impact your home’s longevity and curb appeal. This section outlines key factors to consider, including credentials and warranties, to ensure you make an informed, confident decision.

Evaluating Roofing Contractor Credentials

It’s essential to verify the credentials of any roofing contractor. Licensing and certification are critical indicators of a contractor’s legitimacy and adherence to local building codes. A licensed roofer is more likely to be up-to-date with regulations and better equipped for roof repairs. Memberships in professional bodies can also indicate a commitment to quality and ongoing education.

Experience matters immensely. Choosing a roofing contractor with a proven track record and experience with your specific roofing material, whether architectural shingles or another style, ensures they can handle the job’s complexities. References and reviews from past projects are invaluable for assessing reliability and workmanship quality. Always request to inspect previous jobs, especially if they used similar materials and styles, to get a sense of the finished product.

Local familiarity is another plus. Contractors who understand local codes and climate conditions, such as in Florida, are better candidates for the job. Estimates should be thorough and detailed, covering all aspects of the project, including labor, materials, and additional costs.

Understanding Warranty and Insurance

A solid warranty can offer peace of mind by protecting your investment. Reputed contractors typically provide warranties that cover both materials and labor. Ensure the shingle warranties align with manufacturer guarantees, which can vary widely in terms of coverage duration and conditions. Verify what the contractor’s warranty covers specifically, from defects in materials to problems arising from improper installation.

Insurance is equally critical. Reliable contractors should have general liability insurance and worker’s compensation to cover any accidents during shingle installation or roof repairs. Ask for proof of insurance to protect yourself against potential liabilities. Fully insured contractors ensure that any injury or damage incurred during the project doesn’t fall on the homeowner.

Regulations and Industry Standards

Roofing projects must comply with building codes which vary by location. Local building codes often dictate whether re-roofing over old shingles is allowed. Failure to adhere can result in non-compliance and potential issues during resales or inspections.

Contractors should be aware of the specific codes that apply to their projects. Common regulations include requirements for ridge vents for proper ventilation, securing drip edges, and ensuring proper installation in roof valleys to prevent water damage.

Reroofing standards are set to maintain safety and longevity. For example, architectural shingles might be required in some areas for their durability. Using new tar paper underlayment is typically necessary to protect the structure beneath the shingles.

Ensuring there are no defects in re-roofing work is critical. Proper techniques include using a circular saw to cut shingles accurately and securing them as per code. Full replacement might be mandatory if the roof structure shows significant damage.

Roofing products used should meet industry standards for performance. This includes quality checks for resistance to weather conditions and long-term durability tests. Proper installation techniques ensure compliance and effectiveness of these products.
