Roof Warranty Options Explained

Installing a new roof or replacing a damaged one can be a costly undertaking. This is why it is important to ensure that you use quality materials. At Greater Purpose Construction LLC, we source and install high-quality roofing products to help you maximize the value of your investment. Working with us gives you access to roofing products for different projects and budgets. We also stand by the quality of our roofs, offering warranties with nearly all of our products.

Our Roofing Warranties

GAF shingles roof warranty

Greater Purpose Construction LLC sources and installs shingles from GAF, the largest shingle manufacturer in the US. When you choose GAF shingles, you can expect a winning combination of performance and value. With these shingles, you also get a variety of styles and colors to choose from to complement your home and taste. Our GAF shingles carry a 50-year warranty against defects. In the event that the shingles fail, the manufacturer will replace everything at no extra cost. Specifically, GAF warranties cover the cost of new material, labor, and disposal of waste from the site.

IKO shingles

If you’re on a tight budget, look no further than Greater Purpose Construction LLC for affordable shingles. We install IKO shingles, one of the most affordable lines of shingles in the US, allowing you to find roofing products at competitive prices. But low prices don’t mean you’re sacrificing appearance, quality, or longevity. Our IKO shingles come with both standard and upgraded roof warranties.

A standard IKO warranty is 15 years, prorated, meaning that the manufacturer will cover less of the repair and replacement costs over time. This type of warranty only includes the cost of the material.

An upgraded IKO warranty is 20 years, prorated. The warranty lasts for 20 years and includes the cost of materials, labor, and disposal.


Metal roofs do not carry a warranty since the material lasts forever. However, these roofs need repainting from time to time to maintain their appeal and protect them from the elements. The warranty offered on metal lasts just as long as the paint’s warranty lasts, a period of between 25 and 40 years.

TPO roof warranties

TPO roofing membranes have become increasingly popular, owing to their excellent performance and installation advantages. The roofing product is reliable and resists corrosion, helping to protect your investment. Our TPO roofing has a standard 10-year manufacturer warranty. However, 15 and 20 year extended warranties are also available. In case of defects on the TPO, you are covered by the manufacturer. This includes replacing the TPO, paying for the new material, labor, and disposal.

The fine print

Most warranties come with restrictions, and roofing warranties are no different. For these roofing warranties to apply, property owners must ensure proper maintenance of their roofs. This includes removing leaves from the roof surface regularly to safeguard against damage and installing quality gutters to carry water off the roof.
