Today in our master class,
We’ll learn more about parapet (secret roofing), its INs and OUTs, and why it’s a good option, and reasons you may have issues with it (leaking).

Let’s get started
The advantages of parapet roofing are but not limited to;
1. It’s cost efficient
2. Requires fewer roofing materials
3. it’s modern (aesthetics)
4. easy to install

But the big question is,
“Why does secret roofing have so many problems; Leaking especially, WHY?
Secret roofing is a bit tricky and funny to construct. It’s no secret that most artisans discourage people from doing secret roofing, because they’ve limited knowledge.

I’ll run commentary on some basic errors people make when installing secret roofs and juxtapose it with some suggested solutions.

1. Choice of Roofing Sheets
The first problem I’ve realized with many secret roofs is the type of sheets used. Using standard roofing sheets instead of long span. This is the genesis of the menace.
Using standard roofing sheets will necessitate the use of nails to join several roofing units.
This practice leaves the roofing system with a lot of perforations, which later serves as conduit for water to percolate. The gentle slopes of secret roofing does not allow quick run-offs of water. Therefore, the longer water stays on top of the roof amidst nails and overlap fractures, the higher the chances of leakages.

On the contrary, long span sheets are cut according to your roof dimensions and it covers the entire roof stretch without joining separate pieces. The absence of nail holes and overlaps makes it almost impossible for water to pass anywhere.

2. Gutters
Gutters (marked blue) are made to collect water from the roofs.
Some artisans use normal blocks and mortar to create the parapet wall on the slab, forgetting that block and mortar joints cannot prevent water percolation. It’s just a matter of time until they lose their bond.

There are special ways of constructing these gutters. One way is to raise a concrete

My advice to engineers and builders.

If your client wants you to implement something that will affect the structural aspect of the work.

Resist and explain why that will not be possible.

If the persist, tell them to put it on the paper and sign with their photography that if any thing goes wrong on that aspect they will be the one to be held responsible.

Boom, they will run away.

The problem with some of the engineers and builders is the boldness to tell their client the basic truth because of money.

This profession needs honesty, truthfulness and boldness.

Enjoy your day.

Happy 🆕 month to all my wonderful clients
