"Quick! Super clean work site. Roof removal is messy! Except for the beautiful new roof you canâ t even tell they were here! It looks so good with the new paint color."

"I really liked the work"

"Excellent product! The lifetime warranty provides priceless peace of mind in an area prone to hail and high winds. The style of material created a unique and attractive upgrade to our home. Owner was extremely knowledgeable and patient answering all our questions. NO pressure sale!! Most importantly, owner was on-site performing the install w/his crew no subcontractors. His craftsmanship attention to detail is precise. Impressive clean up of site afterwards. Thoroughly pleased."

"They replaced the garage roof at my home.  It took forever to hear from them once we signed the contract.  The Roof itself looks great.  They kind of just showed up whenever the mood struck.  No specific times were ever given, even after they told us they were coming to do the roof.  The price was not what was agreed upon in the contract.  I called & asked if it was possible to have an approximate date (even within a week) when they were coming & they flat out said "No".  Most of the roofers did not speak English, so that was a problem.  They did not do a good job of cleaning up after themselves.  If I had not looked in the driveway after they left, I would have run over a nail!!  There were also other stray nails on the sidewalk & in the grass.  They did not do a very good job of cleaning up the whole area.  They were great until they got the contract signed... then not so great."
