We contracted Duane Mainardi Builders, LLC of 101 Marbel Avenue, Marlton, N. Jersey 08053 to replace roofs on Mainland Condominium Corporation's condos in Vineland, N. J. From their very informative personal proposal to their completion of the first phase of 6 double homes in our community, I find that they are totally professional, competent and efficient. They showed up at 7:00 a.m. with a large crew of experienced roofers and completely removed double roofs and damaged plywood and installed new GAF guaranteed roofs to each double condo and cleaned up and left the premises by 4:00 p.m.

The end result is beautiful and has already been tested by rain, snow and high winds. I would unequivocally recommend them as roofers. We intend to use them for the next phase of roof replacements in the very near future.

Duane was very responsive and knowledgeable from start to finish. I received an estimate in a timely manner that was very competitive. The crew was on time and professional. It was a positive experience and I will be recommending Duane Mainardi roofing to friends and family. Service: Roof installation

We were extremely happy with this company from the time of the estimate until the completion of our roof. Duane was extremely knowledgeable and honest with us about what our roofing needs were and he was always available to answer our questions and address our concerns. The people he sent out to replace our roof were professional and personable and from start to finish we could not have asked for a better experience. We highly recommend this company! The Hazen's.

Duane Mainardi is the real deal. 3rd generation builder. He knows it all and proves that to you when you first meet him. He literally takes every piece of material off of his truck and explains the entire process to you while providing you with the estimate. When he leaves you have no doubt that he's going to do the best job and not cut any corners(it's a roof, you may regret cutting corners). In 24-48 hours you will be emailed a full detailed estimate and then mailed a copy of the estimate, insurance, and details of the 100's of houses that he's completed within your area.

Every other estimate I received before him was a 1 page form that was completed in 5 minutes at your house while you weren't there. And their estimate was on par with the other 2 that I received. You will not be disappointed. He and his crew are masters at their craft. If you don't believe me, check out their website. There's hundreds of photos of houses they've completed(to include information on shingles used), a tool that shows you what the shingles will look like on your house, as well as a video that tells you why he's the best of the best.
