"Finding skilled pros to work on a Blue Slate roof and replace a Yankee gutter is hard enough, but Alte was more than just proficient at doing so, they "nailed" it. The crew arrived around 8am and the entire job was cleaned up by 3:30pm. New copper, new slate, cleaned up and it looks and performs beautifully! Professional, courteous and a fair price for a great value."
"They were awesome!! Only roofing company I’ll use from now on! Dan and his team are so professional, and truly care for their customers. 10/10 recommend!! The team came to repair my roof, and cleaned everything up as well. They handled the entire process extremely well, and will be recommending them to all my friends and family from now on"
"Dan and his team are so professional. They arrived a few days after calling for an appointment, and took care of my family. They are the best company in the NJ area!! 10/10 they were so respectful and professional, I am amazed by the wonderful work."

- "Alte did an awesome job replacing the roof on my home. I was nervous since the house was built in 1829. They cleaned up great, no nails in the driveway, no debris. I was waiting for a check from my home insurance company and they did not rush to get their payment. I highly recommend their services."
- "After significant due diligence, I chose Alte Exteriors to install a new GAF Asphalt roof on my house. Alte has been in business for 50 years and is clearly very experienced in roof installation. Dan and his team were prompt, friendly, and very knowledgeable. The crew worked diligently from sun-up to sun-down. They were very respectful and attentive to the property. I had direct access to Dan and Mike (project manager) throughout the project. Both communicated quickly and precisely. I am confident their responsiveness will continue post the project if needed. My new roof looks fantastic! If you need a new roof Alte Exteriors is your "go to" roofer!"
- "Extremely professional contractor. I met with their salesman who went over their products and services offered. Very prompt turnaround between time I signed my contract to scheduling my roof install. Alte team of professional installers covered around the property making sure none of my landscaping was damaged by debris. Installation and clean up took half a day. The crew cleaned up everything and left my property looking as it was before. Project manager met with me after the instillation was completed to make sure I was satisfied with the job done. Highly recommend these guys."
