Concrete Roof Replacement
Concrete roof replacement is what BST Roofers handles when a poured deck or concrete tile roof starts cracking, spalling, or holding water it should shed. We are licensed and insured, and the finished work carries a warranty. Get a free estimate and we will give you a same day quote.
Signs your concrete roof needs replacing
A concrete roof fails slowly, then all at once. These are the signs we get called out for most.
-
Visible crackingAcross the slab surface, often widening after freeze-thaw cycles.
-
Spalling concreteThe surface flakes and exposes the reinforcement underneath.
-
Water poolingIt sits more than 48 hours instead of draining off.
-
Sagging or deflectionThis can point to a weight load problem in the structure.
-
A failing waterproof membraneIt lets moisture reach the slab below.
Cracking or spalling that followed a storm belongs on our storm damage inspection page instead.
How we assess and replace a concrete roof
We treat a concrete deck as a structural job first, a roofing job second.
-
01
Structural inspection
We check the slab for cracking, spalling, and weight load concerns before scoping the work.
-
02
Tear-off
The failed surface and old membrane come off down to sound, reinforced concrete.
-
03
Crack repair and resurfacing
We repair and resurface the slab so it is ready to waterproof.
-
04
Membrane installation and drainage correction
A new waterproof membrane goes down, and drainage gets corrected so water stops pooling.
A concrete roof is one type of low-slope system. Our low-slope roof replacement page covers the wider range of flat-roof work we do.
What affects your replacement cost
Every concrete roof prices differently once we have seen the slab. Four things drive the number most.
Estimates are free, and we can usually turn around a same day quote after walking the roof.
| Cost driver | How it affects price |
|---|---|
| Square footage | Larger roofs mean more material and labor hours. |
| Extent of structural damage | Deep cracking or exposed reinforcement adds repair time before resurfacing starts. |
| Tear-off complexity and accessibility | A hard-to-reach roof or multiple layers raises labor cost. |
| Permit requirements | Structural work often needs a permit, adding time to the schedule. |

Built for every flat-roof property
We replace concrete roofs on residential homes, multi-family buildings, and Brooklyn brownstones, as well as apartment buildings, commercial properties, and mixed-use flat-roof buildings. The slab and the load on it differ by building type, and we scope each one accordingly.
Larger commercial and mixed-use jobs are covered in more depth on our commercial roofing replacement contractor page.
Concrete roof replacement FAQ
How long does a concrete roof replacement take?
A residential job typically takes a few days to a week. Structural repair, slab size, and weather can add time, and we give you a firm schedule once we have inspected the roof.
Can you repair cracks instead of a full replacement?
Yes, when the slab itself is sound. Surface-level cracking over intact reinforced concrete can often be fixed with crack repair and resurfacing instead of a full tear-off.
Do you handle multi-family or commercial concrete roofs?
Yes. We replace concrete roofs on brownstones, apartment buildings, and commercial and mixed-use properties across Brooklyn, scheduling around occupied units where needed.
Is the estimate really free?
Yes. We walk the roof, assess the slab, and give you a written quote at no cost, often the same day.
