An old roof rarely fails all at once. It's a damp patch on the ceiling one monsoon, a hairline crack the next, and upstairs rooms that get hotter every summer as the coating wears thin — small signs of water damage building toward a bigger repair bill. Whether you searched for roof waterproofing, heatproofing roof protection, waterproof in roof solutions, or proof roofing for a house that's already built, this is Ghar Plans' service for restoring that protection properly on an old house — not just patching the spot that's leaking today.
How Ghar Plans Restores an Old House Roof
This service takes a roof that's already showing wear — leaks, heat coming through, or both — and rebuilds its protection in four stages:
Step 1: Primer Coat. The process starts with a primer coat of Sikalastic-510, applied to prepare and strengthen the existing roof surface before any waterproofing goes on. On a roof that's already been through years of sun and rain, this coat is what gives everything applied afterward something solid to bond to, rather than sealing over a weak or chalky surface.
Step 2: First Waterproofing Coat. With the surface prepared, we apply the first full waterproofing coat of Sikalastic-510 across the roof. This is where the actual sealing begins — closing off the hairline cracks and worn patches that have been letting water in, and starting to build the heat-reflective barrier that keeps the rooms below noticeably cooler.
Step 3: Fiber Mesh Reinforcement. Next, fiber mesh is installed over the first coat. Embedding the mesh into the system, rather than leaving it exposed, reinforces the waterproofing layer from within, so it resists cracking again as the roof continues to expand and contract through Pakistan's weather — the same movement that likely caused the original damage.
Step 4: Top Coat. The process finishes with a top coat of Sikalastic-510 applied over the mesh, sealing the entire system. What's left is a continuous, jointless, heat-reflective waterproofing layer — your roof's protection fully restored, not just patched at the one spot where it was leaking.
Together, these four stages take a roof that's already lost some of its protection and rebuild it from the surface up. If your roof also has deeper damage — larger cracks, structural wear, or old coating that needs to be removed first — our team assesses that on site before this system goes on, so what you get matches your roof's actual condition rather than a one-size-fits-all job.
Restoring Protection Before Water Damage Gets Worse
By the time a roof is old enough to need this service, water damage usually isn't hypothetical — it's already visible somewhere, even if it's just a faint stain or a room that runs noticeably hotter than the rest of the house. Left alone, that damage doesn't stay put: a small roof leak becomes a damp wall, then cracked plaster, then a repair bill far bigger than the roof itself. This service is Ghar Plans' answer to that — proper waterproofing of roof and heatproofing materials applied once, so the damage stops spreading and the roof goes back to doing its job.

Frequently Asked Questions
What does this roof waterproofing and heatproofing service include for an old house?
Four stages, all built around Sikalastic-510: a primer coat to prepare the surface, a first waterproofing coat, fiber mesh reinforcement, and a final top coat that seals the system.
What waterproofing materials does Ghar Plans use for old house roofs?
The core waterproofing materials are Sikalastic-510 — a liquid-applied, heat-reflective coating — applied in multiple coats, with fiber mesh embedded between them for reinforcement against future cracking.
What's included in the waterproofing of roof process before heatproofing starts?
On this page's process, waterproofing and heatproofing happen together rather than as separate stages: the primer and first coat of Sikalastic-510 seal the roof, while the same coating system reflects heat once it's fully applied and finished with the top coat.
Is heatproofing roof protection included, or is this waterproofing only?
Both. Sikalastic-510 is a heat-reflective “cool roof” coating, so the same coats that waterproof an old roof also reduce how much solar heat it absorbs — you don't need a separate heatproofing product on top.
Does this service include repair work like crack filling if my roof has deeper damage?
If your roof has larger cracks, structural wear, or old coating that needs removing first, our team addresses that as part of an on-site assessment before this system goes on — message us with your roof's condition and we'll confirm exactly what your roof needs.
What's the difference between this service and your water damage prevention service for new houses?
This service is for a roof that's already built and already showing wear — it restores protection that's degraded over time. The new-house version is applied during construction, before the roof has anything to protect yet, so it prevents that damage from happening in the first place rather than restoring it after the fact.
Which cities does Ghar Plans provide this service in, and how do I book it?
This service is currently available in Lahore, Sialkot, Rawalpindi, Islamabad, Gujranwala, and Gujrat. Message our team on WhatsApp or reach out through our Contact Us page with your city and your roof's condition, and we'll arrange a site visit.
