About Our Company


Built On Integrity

Since our inception in 1989, Advance Roofing, Windows, Siding & Doors has become widely recognized as the Delaware Valley’s first choice for exterior remodeling projects. President and Founder, Gary Derrick, began working in the remodeling industry at a very young age and in doing so gained valuable insight into delivering top quality products and a great customer experience. As an engineer, Gary worked in the vinyl replacement window manufacturing business where he learned the importance of offering a premium product coupled with professional installation, all at a reasonable price.
With Gary's experience,  Advance Roofing, Window, Siding & Doors is dedicated to offering superior building products installed by certified professional installers at a price that’s affordable.

Our Promise

All building products offered by Advance are accompanied by a comprehensive no nonsense warranty that homeowners can rely on. Advance proudly boasts a Lifetime Workmanship Guarantee on all products we install. Advance is a family owned business that is fully bonded, licensed, and insured. We look forward to making your remodeling project a great experience; from start to finish.
Our success as a company has everything to do with being up front, fair, and honest with our customers. Because we control everything about our Roofing, Windows, Siding and Doors – from measuring to installation and service – we stand behind the promises we make. We hope you’ll give us the opportunity to show your family how our products can enhance the beauty, comfort, and efficiency of your home. Please give us a call for a free estimate and find out just how affordable your next project will actually be.
