Why people call

Three ways a roof problem lands on your desk

The first step is always the same. A qualified contractor looks at the entire roof, and you get photos, a trusted opinion, and documentation you can hand to whoever approves the next step.

The roof is aging

Nobody can tell you how much life is left or what to budget.

Know your options

Repair, restore, or replace?

The recommendation starts with the roof, not a predetermined solution.

Repair

A localized problem with useful roof life remaining. Address seams, flashings or damage at the source.

Explore repair options

Restore

A roof suitable for restoration may benefit from coating after preparation and necessary repairs.

Explore restore options

Replace

When the system is beyond practical repair, plan a reroof around your building and budget.

Before you call

Common questions

Do you do residential roofs?

No. Commercial, industrial, institutional, and municipal buildings only.

Can you repair a roof you didn’t install?

Yes. We’re approved by the major commercial manufacturers, so repairs on warranted roofs stay within the warranty terms. Bring the warranty paperwork if you have it; we’ll work to it.

Will repairs shut down part of my building?

Rarely. Most of our work is on occupied buildings. Access, safety, and timing are set with your team before we’re on the roof.

What do I get after an inspection or repair?

Photos of what we found, a plain-English recommendation, and a record you can forward. Maintenance customers see all of it in the TotalSENS portal.

How far will you travel for a repair?

Repair crews cover roughly an hour from Ephrata: Lancaster, Lebanon, Berks, and nearby York and Dauphin. Larger reroof projects go further. If you’re unsure, call and we’ll tell you.

Is the inspection really free?

Yes, for commercial and institutional properties in our service area. No report fee, no obligation.

What’s the difference between the emergency line and the office?

The emergency line is for water coming in now. For everything else we call back during business hours.
