How long does a typical roof installation take?

Most residential roof installations take 1-2 days depending on the size of your home, roof complexity, and weather conditions. We work efficiently while maintaining the highest quality standards. For new construction projects, we coordinate with your builder's timeline to ensure proper sequencing with other trades.

What's the difference between tear-off and overlay installation?

Tear-off removes all old roofing materials, allowing inspection of the roof deck to identify and repair any damage before the new roof is installed. This provides superior long-term performance and lets us upgrade ventilation and underlayment. Overlay installs new materials over the existing roof, which is faster and less expensive but doesn't allow deck inspection and provides less warranty protection. We recommend tear-off for most residential applications.

What roofing materials do you recommend for Indianapolis homes?

For Indiana's climate, we most commonly recommend GAF Timberline HD or Owens Corning Duration architectural asphalt shingles for excellent value and 25-30 year performance. For premium options, metal roofing offers 40-70 year lifespan with superior energy efficiency. We also install high-end composite and slate alternatives. We'll recommend the best option for your home's style, budget, and long-term goals.

Do you guarantee your installation work?

Yes, absolutely. Every installation we complete is backed by the manufacturer's warranty (typically 25-40 years depending on materials) plus our quality guarantee. We stand behind our workmanship and are confident in our professional installation standards. We provide complete warranty documentation so you have full protection.

How important is attic ventilation in roof installation?

Ventilation is critical for roof longevity and energy efficiency. Proper ventilation reduces heat and moisture buildup, prevents ice damming in winter, extends shingle life, and improves overall home comfort. During installation, we assess your home's ventilation needs and specify continuous soffit and ridge ventilation or powered systems. This is one area where cutting corners during installation can lead to problems later.

Can you install a new roof over my existing roof?

In some cases, yes. If your existing roof is in good condition and your home's structure can support the additional weight, we can install new shingles over the old ones. However, this doesn't allow inspection of the roof deck and limits our warranty. We typically recommend tear-off for most homes because it allows proper inspection, better long-term performance, and optimal warranty coverage.

New Construction Roof Installation

When building a new home in the Indianapolis area, the roofing system is one of the most critical components for long-term protection and energy efficiency. Our team works closely with builders and homeowners to specify and install roofing systems that meet the highest quality standards while staying within budget.

We handle all aspects of new construction roofing, including structural coordination, proper ventilation planning, underlayment selection, and flashing details. Our contractors are experienced with coordinating with other trades to ensure proper installation sequencing and minimize delays. We use premium materials from trusted manufacturers like GAF, Owens Corning, and CertainTeed to ensure your new roof will perform beautifully for 25-50+ years depending on the material chosen.

Roof Replacement

Professional Re-Roofing & Material Upgrades

Re-roofing an existing structure presents unique opportunities to upgrade your home's protection and appearance while maintaining your current structure. Whether you're replacing an aged asphalt roof or transitioning to a premium material like metal or architectural shingles, our installation process is meticulous and non-disruptive to your daily life.

SPG Roofing provides two installation methods: complete tear-off (removal of old materials) or overlay installation when the structure permits. Tear-off roofing gives us the opportunity to inspect the underlying roof deck, repair any damage, upgrade ventilation systems, and install premium underlayment and flashing. This method provides the best long-term performance and allows us to address any hidden damage before the new roof is installed.

Our re-roofing projects include removal and proper disposal of old materials, roof deck inspection and repair, ventilation upgrades, installation of ice and water shield in vulnerable areas, new flashing at all penetrations, and premium shingles or roofing materials. We protect your landscaping and property during the entire process and provide daily cleanup to maintain a safe job site.

Quality Materials

Premium Materials & Ventilation Systems

The materials you choose for your roof installation directly impact durability, energy efficiency, curb appeal, and maintenance requirements. SPG Roofing partners with the industry's leading manufacturers to offer homeowners options that suit their budget, climate needs, and aesthetic preferences.

Asphalt shingles remain the most popular choice, offering excellent value with modern architectural shingles providing superior appearance and performance. We also install metal roofing, offering outstanding durability and energy efficiency with standing seam, metal shingle, and corrugated profiles. Premium options include composite shingles, slate alternatives, and specialty materials that can transform your home's appearance while providing exceptional protection.

Proper attic ventilation is essential for roof longevity and energy efficiency. During installation, we assess your home's ventilation needs and specify continuous soffit and ridge ventilation, or powered ventilation systems when needed. Correct ventilation reduces heat buildup, prevents ice damming in winter, and extends shingle life significantly. We also install premium underlayment systems that provide additional protection against wind, water penetration, and condensation—critical for Indiana's variable weather conditions.

SPG installed a new roof on our new construction home. Their attention to detail was impressive—they coordinated perfectly with other trades and the roof looks fantastic. They explained everything about ventilation and how the system works. Highly professional team.

Jennifer MartinezIndianapolis, IN

We re-roofed with architectural shingles and couldn't be happier. The crew was efficient, respectful of our property, and the final result exceeded our expectations. Great warranty coverage and they left everything spotless.

David ChenFishers, IN

Excellent service from start to finish. They identified issues during the tear-off that would have caused problems later and fixed everything while they were at it. Fair pricing and they stand behind their work completely.
