Most commercial roofs last 20-30 years. If yours is approaching this age with multiple issues, replacement prevents escalating repair costs.
When the same areas leak repeatedly despite repairs, underlying membrane failure typically requires full replacement.
Wet insulation and failing membranes waste energy. Cool roof replacements can reduce cooling costs by 15-30%.
Current building codes require improved insulation and drainage. Replacement brings your building up to modern standards.
A new warranted roof increases property value, improves tenant satisfaction, and makes selling or refinancing easier.
New roofs come with manufacturer NDL warranties covering materials and workmanship—no more repair surprises.
