Building Using Insulated Roof Panels.


Recommended Posts

In Cebu, Union Galvesteel is located in Consolacion (or was it Liloan - not sure where boundary is.. I think on Consolacion side though) right on the North Coastal Road, on the ocean side, about 1/2 way from the old Cansaga Bay bridge to the spot where the north coastal road joins back up with the main Cebu North Road in Liloan. It's a big place. Looks like a factory. They open at 8am. When you get there go through security and you'll be given a priority number (e.g. now serving number 8.. at 8:15 I was # 2 in the line) and sent into the main office. Most of the people arriving there are contractors who know what they want.. and some owners. Walls have lots of samples of the various products. They'll bring out a specialist.. and for those of you who've shopped at places like Wilcon you are in for a pleasant surprise.. as these specialists really do know their stuff. Even the receptionist in that room is very knowledgeable. If you talk to her about the stuff she might surprise you.

 

riklynbor is right, I think, that the Galvesteel he's using (i.e. bonded with insulation) is made at main Manila factory and was shipped to him from Manila. The Galvesteel I used was "made" in Manila as well, but is shipped to Cebu in a big roll.. and is unrolled and "formed" and cut to length there in that Consolacion factory. The Consolacion factory does not have the ability to apply the colour to the metal.. or fasten the insulation riklynbor used.. but it can do most "cut to order" on more standard jobs (i.e. without the insulation). I think Consolacion maintains inventory of all the standard colours.

 

If you do go to their office, it's a good idea to take your roof drawings with you, and the drawings of the roof beams and trusses. Photo's if you have them. If you ever place an order with Union Galvesteel they will need your full drawings, and measurements, because they cut all the roof pieces to order. which means a lot less waste for you.

 

Which reminds me.. riklynbor how did they do with the lengths of your pieces.. did you need to trim them? or was length good already?

 

Well as my intro says I am a jack of all trades and people who know me well will tell you I'm a master of some lol.

I  designed this house from the foundation up every measurement is mine there is not one thing I do not know about this house or one part I have not worked on. I worked out what I needed and order that. The panels are made to order they dont come in standard lengths.

I was blessed with good hands and a brain that wants to learn everything. Realy sounds like I'm blowing my own whistle here lol. But it is just who I am. :yourock:

So tired but there is progress. Fresh pictures hot of the press. Almost half the roof panels are up. First impressions are good. Today in the sun roof hot to touch but beautiful and cool underneath.

I haven't been this excited about pictures since I found my dad's playboy magazine at 9 yrs old.thanks

I am still around. The 8 meter wide folding doors are installed and look magnificent. The whole house is to be proud of. Still building it as we save money. No I am not on the Dole and nobody is givi

For my Texan friend Lavoy and I we had the opposite problem. We each wanted to build a house, fairly similar in size, in our chosen municipality WITHOUT having as much ability as you to be able to do as much of the work. Trust me when I was younger I would love to have rolled up my sleeves and got into it like you are in these photo's.. and I did do that with my first house in Canada.. and my second. But age makes it less and less a possibility unfortunately.. and Lavoy was 72.. so it really wasn't an option for him.

 

So Lavoy and I worked away at it as best we could.. Our first designs were done by the moonlighting municipal engineer who would have had to approve the plans, and he quoted on the full building cost at same time.. and after about a month of scratching our heads both Lavoy and I concluded he was both full of shit.. and trying to make as much as he could. In the end Lavoy got plans done through his wife's sister (friend of some cousin) and his wife's brother-in-law Hermes.. was Lavoy's foreman. and Lavoy had the entire house built while he was in Texas.. starting around 1 June 2013 and finishing 1 November 2013 all via phone calls.. while Lavoy and I reviewed costs and photo's as he went. Then I arrived to help him 1 September and he arrived 1 October. I'm sure that there was some wasted money, but really.. not much. Hermes proved to be a REALLY honest man (impeccably honest really), and he did such a good job that I hired him, and his entire construction team, to build my house after he built Lavoy's. The only difference is that I was there for the full job, rather than trying to do it from a distance. I wouldn't recommend that ANYONE do it the way Lavoy did.. from a distance.. simply too many things you need to be right there for. Small decisions.. like what color for XX or what size for YY.

 

Anyway.. the construction team moved from Lavoy's house to mine around 1 November 2013 (a week before Yolanda). By that time I had drawings prepared by the engineers at my local university, and I had all of Lavoy's monthly cost summaries, and I put together the building permit application and submitted it.. didn't get approved until about 4 weeks after I'd already started construction, but that proved not to be an issue. And away we went. and by the end of March 2014 we were moved in, with all tiles done, but lots of painting still going on (oh.. and no working kitchen.. cooking over a fire out back), and by May 10 or so the last construction guys left. and thankfully I stopped spending money.

 

Would have been nice to be as involved in the daily work as you.. but then as age happens there's lots of things I could say that about.. and wishing ain't gonna make it happen.. so one must be more accepting of one's limits.

 

There was still lots for me to do though.. as buying stuff for all the "finishing touches".. like plumbing and electrical fixtures.. kitchen counters.. tiles.. paint.. and 1000 other small details consumed LOTS of time nonetheless. I own a 1995 Toyota Tamaraw there.. it's a member of the family.. and the old girl carried lots of stuff back over the mountains from the city.. one load was close to 2000 pounds of just paint and paint related supplies.

 

Great experience.. enjoyed it all.

Well dave we had similar problem. Î drew up the plans for it house as we would in Australia but that was not acceptable here so I had to get a local architect to redraw my plans but up to Pinoy specs. He also offered his services to oversee the build for a fee of P250,000 he would go and check the house sometimes. Also his materials list was a bit to be desired one item that was on the list that made me suspicious was paint well the 200 litres of primer and 600 litres paint he wanted money for to buy. I did not use his services either.

Even though the house is costing more than his quote we have used materials not in his list such as steel decking, stronger concrete, more concrete, or own CHB and the roof panels to name a few. Also a lot more glass than in the original design. I think or cost wil be about 40% higher.

In my area, if someone goes into a hardware store to buy materials on my behalf, they get a commission from the hardware store. So If I send Hermes into the store to buy 5,000 peso of "stuff", then he will get a commission (i.e. cash kickback) of 3% to 5% (150 to 250 peso), depending what items were purchased. Of course, I bought hundreds of thousands of materials in those stores.. so this commission would be quite sizeable over a full project. Likely 30,000 to 50,000 peso.. just for routine building supplies (coco lumber, CHB, rebar, steel, nails, Portland, etc etc).

 

So what I did was I went to the owner of the store and asked him:

 

a) what discount he would give me if I purchased mostly from him

 

b) Would he extend credit, so that Hermes could order supplies whenever he needed, and sign a delivery receipt, and I would go to the store once a week and pay the total.. with all the signed delivery receipts.

 

I think I got an average of about 4% off.. Not HUGE .. but that money remains in my pockets.. not someone elses.

 

And BTW.. This is not "foreigner pricing".. this commission scheme works for everyone. I even bought stuff there myself for 1000 peso.. listed price.. and pay with a 1000 peso note.. and had then give me 30 peso commission.

 

As for the paint I WAS surprised how much we used. The concrete just sucks up the primer like a sponge.. I used mostly Boysen paints.. and a product called Boysen AcriTEX (sp?) which is like a thin putty and which they apply on the walls after the primer to fill in holes and smooth the wall. Then they sand it.. and apply again.. and sand again. and apply again and sand again.. for what seems like forever. Must have used 200 sheets of sand paper at least. All hand sanded. End result does look pretty good though.

 

The lead painter I had was pretty good.. and he taught the wife's brothers how to paint. Before.. they just slopped it on and made a mess and I don't speak enough of the language to correct them. Now, they do quite well.

 

Also my all-in bottom line cost was lower than what had been quoted.. but not by much.. But that's more MY doing than anyone else's, as I decided part way through to put nicer finishes in a number of areas then we originally planned. Simply decided if I'm gonna live there then F**K IT.. I want it comfortable.

There is a hardware store here in Maasin that charges the same price to foreiners as the locals unlike all the other stores. You can tell coz it is where you find foreiners looking for hardware. Mostly if i feel im gettong ripped of ill send one of the workers to get a price for me and if it is lower I will confront them. They drop the price soon enough if you tell them you take your business elsewhere.

This thread has dried up...what happened.??

Glad you miss me hehehe.

Well the roof is finished I guess.

Been back in Australia about 3 months now sadly during which my dad passed away from pancreatic cancer. I was hoping he would one day visit the house.

 

The house is finished rendering and just this last week gave the go ahead to start making the glass windows and doors. Not sure when I will return to Philippines. Would prefer to go with my wife next time instead of alone.

 

Had a accident cooking Pansit behon this week. Find out if tomorrow I need a graft.

No just a small JVC Camcorder. I mounted it on my helmet did quite a good job. Even better before quality was reduced for YouTube.

I'm a (retired) Electrical Engineer, but from a vintage that learned a bit about all sorts of other versions of engineering too.

There was some comment earlier in this thread about roof loading and talk about the weight of roofing material (and people standing on the roof).

Generally, wind loading on roofs dwarfs the above static loads in strong winds.

The basic formula for wind load on a flat plate is:-   ( In imperial units for the benefit of the elderly and Americans - Lol! )

 Pressure (in lbs/sq ft) = knots * knots / 400  ......... so in a cyclone at 100kts (about 110 mph)  P = 25lbs/sq ft

This can add up to a serious load (up or down) on a big roof.

Real calculations need to take account of the angle of the roof to the wind, if there is pressure on one side and suction on the other and a bunch of other things.

A job for an experienced Civil Engineer!

Cheers,

Oz Jon
