Key West falls in Florida Climate Zone 1 under the Florida Building Code, Energy Conservation (8th Edition). That means R-30 minimum for attics, with R-38 being the practical target for real comfort and utility savings. Many Key West homes built before 2005 are still measuring R-11 to R-19, which is a large part of why their summer bills are so high.

Yes. We install both open-cell and closed-cell spray foam throughout Key West, Monroe County. Closed-cell on the roof deck is the strongest option here — it air seals, controls humidity, brings your ducts into conditioned space, and adds measurable uplift resistance to your roof sheathing, which matters in a hurricane-exposed part of Florida.

We answer the phone 24 hours a day, 7 days a week. In Monroe County we can usually be on site for a free assessment within 24 to 48 hours, and emergency insulation removal after a roof leak or storm gets same-day priority whenever we can make it happen.

Cooling is roughly half of a typical Key West electric bill. Bringing an under-insulated attic from R-11 up to a properly air-sealed R-38 commonly cuts the cooling portion by 20 to 30 percent — and more if your ductwork is in the attic and we add a radiant barrier. On a $300 summer bill that's usually $30 to $45 a month back in your pocket.

It depends on your building and your budget, and we'll tell you honestly which one applies. If your attic is at R-13 and you want the most improvement per dollar, blown-in fiberglass to R-38 with proper air sealing is the answer. If your ducts are in the attic and you want humidity control and the biggest total comfort win, closed-cell spray foam on the roof deck is the answer. If your roof is more than twelve years old, do the roof first — we'll say so.
