Recover vs tear-off — which is right for me?

If moisture is low, deck is sound, and code allows, a recover can reduce cost and downtime. Wet insulation, multiple layers, or major design issues typically require a full tear-off.

How long will the project take?

Duration depends on size, height/access, weather, and system complexity. We create a phasing plan to keep entrances safe and operations open whenever possible.

Can you improve drainage and energy performance?

Yes—tapered insulation, new drains/scuppers, and reflective membranes can reduce ponding and cooling loads. We design for both code and ROI.

What warranties are available?

We offer manufacturer system warranties (often 20–30 years) when installed to spec, plus our workmanship coverage. We’ll align warranty terms to your goals.
