Common problems
Flat Roof Problems We Fix Around Venice
Flat roofs fail in their own ways. These are the issues we see most often on Westside homes.
Blisters and bubbles
Trapped moisture or air lifts the roof surface. Blisters can split open in the sun.
Open seams
Where two sheets meet, heat and movement slowly pull seams apart.
Clogged drains and scuppers
Leaves and sand block drains, so water rises and spills over the flashing.
Cracked parapet caps
The short walls around flat roofs crack at the top and let water into the wall below.
Worn-out surfaces
Years of sun dry out the top layer until it cracks like old leather.

Flat Roof Systems We Install, Side by Side
There is no one best flat roof. The right choice depends on sun, foot traffic, budget and how the roof drains.
| System | What it is | Best for | Learn more |
|---|---|---|---|
| TPO | White single-ply sheet with heat-welded seams | Reflective, clean-looking roofs | TPO single-ply roofs |
| Torch down | Layers of modified bitumen bonded with heat | Roofs with some foot traffic | Modified bitumen roofs |
| Built-up (hot mop) | Several layers of felt and hot asphalt, often with gravel or a cap sheet | Older buildings and repairs to existing systems | Covered on this page |
| Roof coating | Liquid layer that seals and reflects | Sound roofs that are worn on top | Roof coating systems |
| Deck membrane | Walkable waterproof surface | Rooftop decks people use | Waterproof roof decks |
Your options
Repair, Recover or Replace a Flat Roof?
A flat roof does not always need a full tear-off. We pick the option that gives you the most years for your money.
- Repair when the roof is mostly dry and the problems are in a few spots.
- Recover by adding a new membrane over the old one, when the old roof is dry and code allows it.
- Replace when water has soaked the insulation or decking, or the roof already has too many layers.
We often use moisture checks to see if the roof below is wet before we recommend a recover. If the wood is damaged, we will add rotted deck repair to the plan.
Drainage first
How We Stop Water From Ponding on Flat Roofs
Flat roofs are not truly flat. They need a slight slope to move water to a drain. When that slope is missing, water sits and the roof wears out early.
- Tapered insulation adds slope under the new roof surface.
- Crickets are small sloped ramps that push water around walls and chimneys.
- Bigger or added drains and scuppers let water leave faster.
- Clear gutters and downspouts make sure drained water keeps moving. See gutter work.
Fixing drainage during a re-roof costs far less than fixing it later. Have questions about our team or how we work? Visit our roofing company home page.

Flat roof questions
Flat Roofing Questions We Answer Daily
Short answers about ponding, roof life and repair choices.
How long does a flat roof usually last?
It depends on the system and how well it drains. Many flat roofs last 15 to 25 years with good care. Roofs that hold water or get heavy foot traffic often wear out sooner.
Is some standing water on a flat roof normal?
A thin film right after rain is common. Water that is still there two days after the rain stops is a drainage problem that should be fixed.
Can I walk on my flat roof?
Light foot traffic for maintenance is usually fine. If you plan to use the roof as a hangout space, it needs a walkable deck surface made for that.
Can a new flat roof go over the old one?
Sometimes. If the old roof is dry and there are not already too many layers, a recover can save money. We check the roof before recommending it.
