Our Services

Inspections

Detailed roof inspections for property purchases, aging roofs, and long-term planning. We assess overall condition, remaining service life, and any problem areas so you can make informed decisions about repairs, replacement, and budgeting.

Repairs & Leak Response

Fast diagnosis and lasting fixes for leaks, seams, flashings, ponding water, and storm damage. We focus on solving the issue at its source to protect your building and minimize downtime.

Preventative Maintenance Programs

Twice-yearly preventative maintenance visits designed to extend the life of your roof. Typical visits include cleaning gutters and drains, removing debris, checking seams and flashings, and addressing minor issues before they turn into leaks.

Installation & Replacement

Full-scope projects for flat and low-slope roofs, including tear-offs, recovers, and code-required upgrades. We handle everything from planning and safety to final cleanup, so your facility can stay focused on business.

Standing Seam

Professional installation of 24-gauge standing seam and metal roofing systems with 25-year paint warranties. Ideal for commercial and industrial buildings that need long-term performance, clean lines, and reduced maintenance.

Metal Roof Restoration

Extend the service life of your existing metal roof with high-performance silicone, acrylic, or aluminum coating systems—often at less cost and downtime than a full replacement, when the roof is a good candidate for restoration.
