Common issues

Solving common commercial roofing problems

Commercial roofs face constant stress from sun exposure, temperature changes, foot traffic, and rooftop equipment. Over time these conditions cause serious problems if left unaddressed. Early identification prevents interior damage and costly structural repairs.

Cracked, blistered or ponding membrane
Deteriorated flashing around units and curbs
Poor drainage causing accelerated aging
Aging roofing materials past service life
03
Repair vs. replace

Expert repairs and full replacements

Not every roofing issue requires a full replacement. Nuon specializes in precise, cost-effective repairs that extend the life of existing systems when the structure is sound and materials are still within service life. When a roof reaches the end of its lifespan, we install modern systems designed to improve durability, energy efficiency, and Title 24 compliance.

Commercial Roofing FAQ

Can you install solar on our existing roof?

+
If your roof has 10+ years of life left and passes a structural review, yes. If it's near end-of-life, we recommend re-covering or replacing before PV goes on so you don't have to remove and reinstall the array in five years.

How disruptive is a commercial re-roof?

+
We sequence work in zones, mobilize early morning, and keep the building operational throughout. Most re-roofs happen without interrupting tenant or warehouse operations underneath.

What warranty comes with a commercial roof?

+
Up to 30-year NDL (No Dollar Limit) manufacturer coverage plus Nuon's own workmanship warranty. NDL means the manufacturer covers the full cost of leak repairs, not a prorated amount.
