Roofs that hold — through monsoon, dust storm, and the next decade.
From a single ceiling stain in the bedroom to a full membrane re-do on a flat-slab villa, we trace the leak before we sell the repair.
Family-owned since 2007. We thermal-image every leak before quoting, write a 10-year workmanship guarantee on the invoice, and use only Sika / SBS-modified bitumen — never the cheap roof-coat that flakes off after one summer.
Roofs are the cheapest insurance you can buy — done right.

Peakroof started in 2007 after master mason Karim Bashir watched a neighbour pay PKR 4 lakh three times in five years for a "waterproofing" that lasted one monsoon. He decided someone in Karachi had to do it the way the spec sheet actually says — primer first, two coats minimum, mesh in the corners.
Today his sons Hamza and Adeel run the field crews. We do roughly 140 jobs a year, mostly referrals. Every roof we touch gets a 10-year workmanship guarantee on the invoice — not a verbal promise.

Concrete-slab waterproofing (RCC roofs)
SBS · PU · Liquid membrane
Slab cleaned, cracks routed and sealed, primer rolled, two-coat SBS-modified bitumen or polyurethane membrane, fibre mesh in the corners and parapet upturns. Ten-year workmanship guarantee.
Leak diagnostics & repair
Thermal imaging · Hose test
Most "roof leaks" are actually a parapet crack, a clogged scupper, or a failed AC drain penetration. We thermal-image the ceiling, hose-test from the roof, find the actual entry point — fix only what is broken.
Sheet roof replacement
GI · Aluzinc · Insulated panel
Old corrugated GI swap-out for insulated sandwich panels (rockwool or PUF core). Less noise during rain, 8–12°C cooler attic, slope corrected for proper drainage.
Parapet & flashing rebuild
Lead flashing · Cement parapet
Failed parapet cap or rusted flashing is the #1 cause of "the roof is leaking" calls. We rebuild the cap, install proper drip-edge, and seal all penetrations with butyl tape under the membrane.
Insulation & cool-roof coating
EPS · XPS · Reflective
50mm EPS or XPS board over the slab, mechanically fixed, then a reflective cool-roof topcoat. Drops top-floor room temperature by 6–9°C in peak summer.
Annual roof maintenance contract
Pre-monsoon · Post-monsoon
Two visits a year. Drains and scuppers cleared, parapet cracks sealed, AC penetration boots checked, photo report emailed. Catches problems before they become lakhs.

Talk to a plumberThree monsoons later — still dry.
Each winter we mail a postcard to last year's clients. These came back.
Three "waterproofing" companies before Peakroof. Every monsoon a new patch, a new bill. Hamza found the actual leak (a hairline parapet crack) on the first visit, fixed it in a day, three monsoons dry now.
They thermal-imaged the ceiling and showed me on the screen exactly where water was tracking — wasn't even close to the visible stain. Saved me from re-doing the whole roof.
