Built by roofers. Run on straight answers.
Delfi Roofing is a roofing and siding contractor working with homeowners across Pennsylvania and New Jersey. One rule runs the company: document everything and tell people the truth about their roof.
Why homeowners keep sending their neighbors.
Most roofing complaints aren't about shingles. They're about not knowing what's happening on your own property. So we work around visibility: photos before, during and after, and one point of contact you can actually reach.
We install quality materials to manufacturer specification, we protect the property while we work, and we clean the site every evening before we leave.
We serve homeowners across Pennsylvania and New Jersey — from city rowhomes to suburban and shore properties that take a beating every winter.
High Quality Work
Roof systems installed to manufacturer specification, with the flashing and ventilation details done properly rather than covered over.
Clear Communication
One point of contact from the first inspection to the final walkthrough, and a straight answer whenever you ask a question.
Clean Job Sites
Landscaping protected, debris removed and a magnetic nail sweep run before we leave your property each day.
Attention To Detail
Valleys rebuilt instead of patched, penetrations flashed correctly and trim lines kept straight — the parts you only notice when they're wrong.
Customer Satisfaction
We walk the finished roof with you, review the work together and don't consider the job done until you're happy with it.
Serving Pennsylvania & New Jersey
Local crews working for homeowners across both states, with free written estimates and fast response.
One point of contact
The person who quotes your roof stays with the project through the final walkthrough.
Clean job sites
Debris cleared and magnetic nail sweeps run before we leave the property.
Honest scopes
If a repair will hold for five more years, we'll tell you that instead of selling a replacement.
