Ponding Water Compliance

Ponding Water On Roof Top - Flat Roof Replacement

Flat rooves are very common in Florida. Older flat roofs have a tendency to pond water following the rain. Florida law now requires installation of tapered insulation if a flat roof ponds water for more than 48 hours. Ponding water heated by the sun’s rays can cause a breakdown of your flat roof materials leading to leaks and other roofing problems.

Mark Kaufman Roofing has been installing flat roof systems in the Sarasota and North Port areas since 1988. We provide the experienced roofers you need for flat roof work and know. We are experts in the commercial roof replacement field and know the correct slope needed to eliminate ponding water. One of the ways we accomplish this is by building up the roof deck with a tapered isoboard underneath the membrane of the flat roofing system you choose.

Iso board Prep for Flat Roof Replacement by Mark Kaufman RoofingBenefits of Adding Tapered IsoBoard

One of the obvious benefits of installing tapered isoboard in the re-roofing process is that the slope created will allow water to runoff. Just a slight slope can prevent water from ponding. Tapered isoboard is a type of rigid roof insulation panel composed of a closed cell polyisocyanurate foam core. It is laminated to a variety of coverings, dependent upon your need. The construction of the isoboard adds insulation to the roof, which can lower your energy bills and add longevity to the life of your roof.

There are many different types of flat roofing systems available for you to choose from. Talking with one of our experts at Mark Kaufman Roofing can help you determine which system would best fit your roofing needs.
