Snow is melting across Chicago — and this is when roof problems quietly surface.

Freeze–thaw cycles, trapped moisture, and ice damming often expose damage that went unnoticed all winter.

Every spring we see:

• Membrane seam separation
• Flashing failures at parapets and penetrations
• Blocked drains causing ponding
• Ice damage at roof edges
• Early-stage water infiltration into masonry walls

By the time ceilings stain or leaks appear, the damage is already advanced.

For condominium associations and multifamily buildings, March and April are the best months for a focused roof condition assessment — before small issues turn into structural repairs or insurance claims.

A proactive inspection now can prevent mid-summer emergency work and unexpected special assessments.

If your building hasn’t had a recent roof evaluation, this is the time.

Design 21 specializes in these evaluations
