We chose Trenton Roofing & Siding for our roof replacement because they are a GAF Certified company. They are also a great value. AJ was our project manager. He was always available for questions and support. The crew was efficient and professional. I am planning to work with this company again for my siding needs.

Trenton Roofing and Siding did an amazing job replacing my roof. They are communicative and professional. Their employees are knowledgeable and helpful. The cost was as expected and not outrageous as some of the other quotes I obtained.
