Why CertainTeed shingles and siding?

CertainTeed has been around for over a century. They manufacture high-quality products, and they stand behind their work.

If you have one of their roofs, it's likely to last you until the day you die (unless you live in an area with frequent tornadoes).

CertainTeed also has a good reputation among homeowners and contractors alike—which means that when it comes time to sell your house, more potential buyers will be interested in buying your home than if you had chosen another brand.

CertainTeed products have a reputation for quality and are backed by a lifetime limited warranty.

CertainTeed products are also made in the USA, supporting American jobs and the economy.

CertainTeed Shingles

CertainTeed roofing shingles are the best solution if you want to protect your home from the elements while maintaining its desirability at the same time.

CertainTeed Siding

CertainTeed siding is an excellent choice for many homes. It's easy to install, offers a variety of styles and colors, and costs about the same as vinyl siding.

CertainTeed siding's durability makes it a long-lasting product that can retain its appearance for decades.
