Why Replace Your Commercial Roof?

Key indicators that replacement is more cost-effective than continued repairs

📅

Roof Age

Most commercial roofs last 20-30 years. If yours is approaching this age with multiple issues, replacement prevents escalating repair costs.

💧

Recurring Leaks

When the same areas leak repeatedly despite repairs, underlying membrane failure typically requires full replacement.

🔋

Energy Costs

Wet insulation and failing membranes waste energy. Cool roof replacements can reduce cooling costs by 15-30%.

📊

Code Compliance

Current building codes require improved insulation and drainage. Replacement brings your building up to modern standards.

🏢

Property Value

A new warranted roof increases property value, improves tenant satisfaction, and makes selling or refinancing easier.

Insulation & Energy Upgrades

Roof replacement is the ideal time to upgrade insulation. We install tapered polyiso systems that eliminate ponding water while dramatically improving R-value. Combined with reflective white membranes, these upgrades can reduce cooling costs by 20-30% and often qualify for utility rebates.

Replacement FAQs

Common questions about commercial roof replacement

How long does a commercial roof replacement take?
Most projects take 2-4 weeks depending on building size, weather, and system complexity. We provide detailed schedules before starting and keep you updated throughout.
Do I need to close my business during replacement?
No, most businesses operate normally during roof replacement. We coordinate work to minimize noise during critical hours and maintain safe access throughout the project.
What warranties are available?
We offer manufacturer NDL (No Dollar Limit) warranties from 10 to 30 years covering materials and workmanship. These are backed directly by manufacturers like Carlisle, Firestone, and GAF.
Should I repair or replace my roof?
Generally, if repair costs exceed 30% of replacement cost, or if your roof is over 20 years old with multiple issues, replacement is more cost-effective long-term. We provide honest assessments.
