How we do flat roof leak repair in Valrico, FL

  1. Find it.Flat roofs hide leaks well. Water can run along the deck before it drips through a light fitting. We trace it from inside and out, and hose-test the house joint if needed.
  2. Check the deck.Soft or stained decking means water has been sitting a while. It gets replaced, not covered over.
  3. Fix the cause.Proper flashing at the wall, re-sealed seams, a patch at the ponding spot. Not another layer of caulk.
  4. Show you.Photos before and after, and a written price before any work starts.

Why only in sideways rain?

A lot of lanai leaks only show when storms blow in against the house wall. Valrico's afternoon storms push rain into that joint hard. See why roofs leak only in heavy rain.

Flat roof leak questions

Why does my lanai roof leak where it meets the house?

That joint is the weakest point on most porch and lanai roofs. Many were sealed with caulk only, which dries out and splits in Florida sun. A proper fix uses flashing and membrane run up the wall.

Is ponding water on a flat roof a problem?

Water that sits for more than a couple of days after rain wears the membrane faster and finds any small split. It's a sign the roof needs better drainage or a patch at the low spot.

How much does flat roof leak repair cost?

Most flat, patio and lanai roof repairs in the area run $500 to $1,200, depending on the size, the membrane and whether the decking underneath is wet.

Can a flat roof be repaired, or does it need replacing?

Most leaks are at seams, edges or the house joint and can be repaired. If the membrane is cracked and brittle across the whole roof, or the decking is soft in several places, replacement makes more sense.

Do you work on screen enclosure roofs?

We work on solid flat and low-slope porch and lanai roofs. Aluminium screen enclosures are a separate trade.
