Honestly, you have really tried for me. It shows the kind of person you are. Someone like you will always get help even from where you are not expecting it. I think I will consider the 2 options you have suggested. I guess I should ask architect to sketch out how the penthouse_like roof will be so that it does not disfigured the house. Also if the cost is negligible, I will put it on 3D just to be sure of how it would be on the house. Then I will still go ahead to do bitumen and felt as suggested. I kuku have an engineer introduced to me by my cousin but it was later I realized that the man is ill experienced engineer. I guess he is only used to bungalow�. Once am convinced that it won't disfigure the house then I will go ahead. I will go to site today and snap the picture of how it is currently and send it here. Thanks for your advice and I really appreciate it.

Did you say Polystrene is cheaper?

The quote l got nearly doubled what l spent on casting in-situ.
or may be the price has reduced drastically in the last three years?

Make l go price am, l might need it around next year

HOuse, please what could be the reason for low water pressure for taps within a house. The water Tank is on a slab on the roof of the duplex. all external taps have very good pressure. i dont want to use a pressure pump.

diordaves:


This is very obvious; not enough gravity. To harvest the required gravity for a good water pressure inside, the water tank should be a minimum of one meter above the levelling blockwork AFTER the lintel. It is possible your water tank is almost practically sitting at the same level as your water heater or shower. You may only experience good pressure if your water tank is full; when half tank, little pressure. This is the classical disadvantage of on roof water tank construction. It needs careful planning and thought. It happens almost all the time with such roof tank adoption. External taps and downstairs kitchen should experience good pressure though. If your downstairs kitchen is not experiencing good pressure as well, look at the plumbing work. Smaller pipework produce better pressure.

For a simple solution, you may need to raise the height of your tank by two or three courses of blocks on the slab and then place the tank on the top of the blocks. You can only adopt this solution if you have the headroom to do so.

That's correct sir. If Location is Lagos, there is a company around Sangotedo axis that sells from N15,000 a piece(A piece is 3 meters i.e N5,000/m) depending on sizes, and labour shouldn't cost you more than N1,500/m

b2212:
thank you so much for this. i will try to raise the tank with some blocks. the house was designed with a slant roof and the slab was placed after 3 coaches. external taps have perfect pressure but kitchen also experiences poor pressure.

Hello great minds in the house.
Please does anyone know where know Air condition supplier that sells those with 4 indoor split units connected with 1 outdoor unit. The individual split units can be controlled independently to different temperature/speed.
Kindly help with supplier contacts and prices.

Thank you.

Is it a good idea to use blocks, considering the weight of the Full-Tank that will be placed on it?
Why not just do small lengths of three feet high concrete beams that the tank will sit on, and then put something flat (like Hard Wood Planks) on it, if you dont want to slab/deck it with concrete?

Like @diordaves said, it has to do with Pressure, size of pipes used.
I have heard Plumbers say If you run the Pipe from the Tank, downstairs first and then run everything (all supply pipes) from there, Upwards, it will equalise/improve the Pressure of upper floors.

Also, there are some "pressure pipes" (if that si what Plumbers call it) that allows air to enter each discharge pipe taking water to each flat from the tank.
The principle as l undersrand it is that as the water reduces in the tank, it takes more effort to suck the water out. If air is not sucked-in (for closed tanks) to replace the water being sucked out, the pressure will fall rapidly. The air-pipes serves to reduce the inside pressure of the tank so it can easily give-up its water to the upper flats especially (increase the pressure).
I have it done when l had same problem and it improved the pressure for the upper flats. Give it a try, if you dont have it already.

This is a wrong approach!

Just tell him to share his drawing here so that professionals and others who can help him, can see it.
If he sends it to your own box, how will others have access to it and advice him, say as Home Owners who have just gone through the same process?
Note: I am not accusing you of anything. I am focused on the sharing of drawing only.


He is not looking for another Contractor, he just wants advice on Pricing, Items included and Quantity

@Chingymas:
It is difficult to offer any advice/suggestions without knowing the parameters of your build.

For example, length of Cables can be affected by the dimensions of your house, even by the shape or how you intend to run the wiring (Conduit vs. Surface). Number of Toilets in the building, where your Overhead Tank is placed, size of Kitchens, presence of Showers, outlet for washing machines, location and number of Septic Tanks, etc, can affect your plumbing needs

This is why your Drawing would help others to give you valuable opinion, aside letting you know how much some items are going for in the market and how many of such you might need, within some measure of tolerance.

You can (if you want), share your drawings here, while removing any sensitive personal information on it.
Just the bare bones.
A current picture of your build that cannot show where it is located, might also come in handy.
You can also share the current Invoice you were given by your workmen.

Cheers.

I plan to roof a single storey building (5-bedroom ensuite) and need rough idea of the total cost using steptile aluminium sheet.

I will also want to know if parapet (cast in-situ and not the precast type) is necessary other than for aesthetic - the advantages/disadvantages. Cost idea for that too will also be appreciated.

Cost for both roofing and parapet should be all encompassing...wood, nail, sheets, etc.
Thanks.
