Excellence Roofing, is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Call us today!

"Excellence Roofing, and it's owner Sal, put more time into the initial inspection of my project, and discussing our concerns, than any of the other contractors bidding the job. I had a complete tear-off to deck (2 layers) and several replacement skylights. Excellence Roofing gave me a competitive bid (not the lowest, but nowhere near the highest) I had 6 contractors providing proposals, although one of them never got back to me. Excellence Roofing had my confidence, and they got the job. From start to finish, Sal and his team performed to the integrity that was promised. I was kept informed and consulted throughout the job. I could see the attention to detail given by all. The job was completed in the expected timeframe, and passed inspection with no issues. Actually, the inspector commented on the quality of work. Last, but not least, Excellence Roofing won't take any money for payment until the job is done and you're satisfied. Excellence Roofing, and it's owner Sal, is my recommended roofer."

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.

"I had siding replaced and very displeased with the entire process. The crew did a poor job for what I paid and have already had to be back out here 3 times in a month to fix their mistakes. Crew cheif never checked the work to determine if the quality was up to the company standard. The crew left the property a mess with my belongings scattered around the yard. They had leftover pieces scattered as well. The craftsmanship and quality was aubpar for the price. No care for the property. Damaged driveway, roof, windows, and garden bed. Chalking already cracking. Large gaps in the siding. Siding already buckeling. Seams not together. Asked to speak to a manager or supervisor multiple times and still no response. I was promised certain tasks at point of sale that company will not follow up on. Over all this company treats their customers as money and gets in and out with little oversight or quality check. I am very displeased with the product I got for the money I paid. Will never recommend."

Flat, foam, or single ply roofing installations and replacements FAQs

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.
