Bulldog Roofing is a family run business that was established in Longmont, Colorado in January of 2015. We believe it is our duty to take care of the people around us. Because of this, we personally take responsibility for the quality of service brought to your roofing project. Our founding partners formed Bulldog Roofing after experiencing how the roofing companies they worked for failed their customers. We created a company with the firm belief of being true to our word. This has been the driving principle behind building our team. We only hire contractors that share these core beliefs, and we never run from our mistakes. If Bulldog is taking the project on it will be up to our standards or we will fix it.

FAQs for flat, foam, or single ply roofing installation and replacement projects in Boulder, CO

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
