Professional Residential & Commercial roofing in Southeastern Pennsylvania and Northern Delaware


I decided on using Martini after seeing them install a new roof on my neighbors home. The same crew came to install my new roof. From start to finish they were great! Dennis, the job foreman, was terrific and a absolute nice guy. The way in which he coordinates the job is amazing. They take pride in their work and the end result is a testament to that pride. I felt they were here to earn our business and not to take our business for granted. We have just scheduled window installation with them based on the roof installation.

They did a great job putting a roof on my home last month. Their estimates were accurate. They finished in one day. They sent around a worker with a magnet to go over my property for any loose nails. They installed the new gutters properly. They delivered what they promised. No high pressure. And very knowledgable salesman and office staff they kept me up to speed. Every step of the way.

During heavy rain and wind, 2nd story gutter and downspout became unattached from my roof, They were able to have someone come out within a few hours and make the necessary repairs during the storm. Excellent job.
