Your home roof is one of its most essential components — the shield that stands between your family and the elements. It protects your home from rain, wind, heat, and snow while contributing to your property’s overall energy efficiency and aesthetic appeal. At Peak Windows & Doors, we understand that a roof is more than just shingles and underlayment — it’s a long-term investment in the safety, comfort, and value of your home.
While our reputation has been built on superior window, door, and siding solutions, we proudly extend the same craftsmanship and dedication to our roofing services. Whether you need a complete roof replacement, a new roof installation, or expert repair, our certified roofing team delivers durable results backed by premium roofing materials and professional installation techniques.
We work exclusively with Owens Corning Roofing, a leading name in the roofing industry known for its innovation, performance, and beauty. When you partner with us, you get more than a roofing product — you get a system built to protect your home for decades.
A properly installed and well-maintained roof provides lasting protection, insulation, and peace of mind. It prevents moisture infiltration, reduces energy loss, and withstands seasonal temperature swings. Over time, however, even the best roofs can show signs of wear and tear.
Cracked shingles, leaks, sagging, or missing granules are indicators that it may be time for a new roof. Ignoring these issues can lead to water damage, mold growth, or structural deterioration, resulting in costly repairs down the line.
By investing in professional roofing services, you not only preserve your home’s integrity but also enhance its curb appeal and resale value. At Peak Windows & Doors, our mission is to ensure that your roof provides lasting protection while complementing the architectural beauty of your home.

As a trusted name in Delaware for home improvement, Peak Windows & Doors is proud to install premium roofing products from Owens Corning, a company recognized for setting the standard in durability, performance, and design innovation.
Owens Corning shingles are crafted with advanced materials that deliver superior protection against weather extremes, algae growth, and fading. Their wide range of styles, textures, and colors allow homeowners to achieve both the look and performance they desire.
Owens Corning isn’t just another manufacturer—it’s a brand known for reliability and cutting-edge roofing technology. Their shingles are designed to endure harsh conditions while maintaining exceptional beauty. Some standout features include:
• TruDefinition Color Technology: Offers vibrant, long-lasting colors that resist fading.
• SureNail Technology: Reinforced nailing zones improve wind resistance and installation precision.
• StreakGuard Algae Resistance: Protects your roof from unsightly dark streaks caused by algae growth.

With Owens Corning, you’re not just getting shingles—you’re getting a complete roofing system designed to perform under all conditions while enhancing your home appearance.

Before recommending a new roof, we perform a complete inspection of your existing system. This allows us to assess its current condition, detect hidden leaks, and identify areas of weakness.

The roof is only as good as the team installing it. Our highly trained technicians follow Owens Corning’s strict installation guidelines to ensure your roof performs as designed. From underlayment and flashing to ventilation and final shingle placement, every detail is executed with precision.

If your current roof has reached the end of its life span, we offer complete roof replacement services. Our experts carefully remove old roofing materials, inspect the deck for damage, and prepare the surface for new installation. This ensures a clean foundation that supports your new Owens Corning roof for decades.

Storm damage and unexpected leaks can’t wait. Our responsive team provides quick solutions to restore protection to your home.

A new roof offers far more than aesthetic improvements. It’s a critical upgrade that delivers lasting performance, safety, and savings.
Older roofs often allow heat to escape during winter and trap excess warmth in summer, driving up utility bills. Owens Corning’s energy-efficient shingles help regulate temperature and reduce the strain on your HVAC system.
Your roof can account for up to 40% of your home’s visible exterior. A beautifully designed new roof dramatically improves curb appeal, giving your home a refreshed, polished look.
Homebuyers value a well-maintained and recently replaced roof. Installing a new roofing adds significant resale value, making it one of the best investments you can make in your property.
A new Owens Corning roof provides unbeatable protection against wind, rain, hail, and UV rays. With advanced waterproofing barriers and superior shingle strength, your home remains secure throughout every season.
When you work with Peak Windows & Doors, you receive the assurance that your roof is built to last. We combine quality craftsmanship with manufacturer-certified materials to ensure your investment stands the test of time.
Asphalt shingles are the most common roofing material due to their durability, affordability, and design flexibility. Owens Corning’s premium asphalt shingles offer superior granule adhesion and advanced color blending for a sophisticated look that lasts.
For homeowners seeking a high-end appearance, architectural shingles provide extra thickness and dimension. These shingles replicate the look of natural wood or slate while delivering enhanced weather resistance.
Reflective roofing options help reduce heat absorption, improve indoor comfort, and lower cooling costs. Owens Corning’s ENERGY STAR-rated shingles are an excellent choice for eco-conscious homeowners.
A complete roofing system involves more than shingles. Proper ventilation, moisture barriers, and underlayment layers are essential for maximizing roof performance and longevity. We ensure that every component works in harmony for optimal protection.
Once your new roof is installed, proper maintenance ensures it performs optimally for years. While Owens Corning roofs are designed for longevity, regular inspections and cleaning can extend their lifespan even further.
We recommend:
• Inspect your roof twice a year, especially after major storms.
• Keeping gutters clear to prevent water buildup.
• Check flashing and sealant areas for wear.
• Removing debris and moss buildup promptly.
Our maintenance programs are designed to catch minor issues early, saving you from costly repairs in the future.
