Roof types
Flat and low-slope roofs
Low-slope roofs are common in Central Florida over porches, Florida rooms, carports, additions and some mid-century homes. Shingles do not work at these slopes, so the roof needs a continuous membrane and, above all, good drainage. Standing water is the enemy.
Low-slope systems
- Modified bitumen, including self-adhered options
- Single-ply membranes such as TPO
- Roof coatings over a sound existing roof, where it is a good candidate
- Tapered insulation or crickets to correct ponding
Where they fail
- Ponding water that sits for days after rain
- Blisters, splits and open seams
- The joint where a porch or addition roof meets the house wall
- Clogged scuppers and drains
- Old patches layered over old patches
Flat roof questions
What counts as a low-slope roof?
Generally a roof with less than about 3 inches of rise per 12 inches of run. Asphalt shingles are not allowed below 2:12 and need extra underlayment between 2:12 and 4:12.
Is a roof coating a good idea?
Only on a roof that is still sound and dry underneath. A coating over wet insulation or failed seams traps the problem. We check before recommending one.
Why does my porch roof leak where it meets the house?
That wall-to-roof joint depends on flashing that is often missing, short or failed on older porches and Florida rooms. It is one of the most common leaks we look at.
