Roofing question

For all the engineers and architects out there,
I have a question regarding roof standards in our country.My sister planned of making her dream house.She hired an engineer and gave the plan she wanted for the house.But the engineer revised the plan and made a plan(with the floor plan/interior close} yet the exterior design is totally different from the original plan.He said the roof is not applicable in our place since we are experiencing rainy seasons a lot.Now she is kind of "not satisfied" with the plan the engineer had revised.Is it really true that the roof in the attached .jpg is not applicable in our country?[img][/img]

nope...! applicable yan...! if you can visit some subdivisions mostly in makati you can see a lot of that kind of roof. there is a proper way of installing that roofing... even here in my place in tagaytay some of the houses here have that kind of roofing. sana makatulong....

nga pla... curious lang... Why approach an engineer kasi not an architect???

Not true at all. as long as nadidrain ang tubig ulan ok lang, kahit anong roof pa yan. basta walang naiipon na tubig na ikasisira ng bubong, ok lang.

You can actually ask a separate contractor who specializes in roofing to do the job. kayang kaya nila yan. good luck!

Simple lang yan bro...
Try to consult an architect in your area, marami dyan magagaling.

not sure with this...good topic to..abangan ko mga sagot sa thread na to.

oo nga,bat sa enginner kayo nag aapproach? dapat sa architect,baka iniisip nya yung budget sa construction kaya ayaw nya yung ganun na roof,di sya kikita

ma engineer man o architect basta ang importante yung quality ang pagka gawa at walang tumutulo.. wag niyo naman e sisi sa engineer mga bro.. na hurt po ako...

tama...pede yan poh sir yang roof...basta may tibay at ganda....

kung yan talaga ang design na gusto ng client, walang magagawa ang engr or contractor kundi sundin yan! kung babaguhin nya yan kelangan nya muna iconsult ang designer den ang designer ang magpapaliwanag sa client sa napagusapan nila! imho lng po...may napuntahan ako place sa bohol na ganyan ang design ng roof, ang problema pag umulan sa window pumapasok ang tubig... maybe un ang dahilan ng engr. pero kung yan talaga ang design, may treatment naman dyan. un lng po, baka makatulong..

Sabi ko na nga ba bro, naisip ko din yan kanina. Pro aside from bawal sa law, Medyo mahihirapan talaga magdesign ang isang engineer. kasi 5 years din na design learning process ang dinaanan ng isang architecture graduate. Although subjective ang design, madaming mga standard ang kailangan matutunan dito. Hindi basta basta ang pagdedesign.

It's good that you are eager to learn the process. kaya bilib ako sayo.

totoo yan ser bok... at sa kabilang side naman, d rin tayong mga architect pwede gumawa ng trabahong pang engr...

applicable yan sir, siguro magandang tanong dyan ang practicality ng ganyang klase ng bubong,,,sa mga nakikita ko kasi, prone talaga sa tulo ang inside gutter pero there are lots of ways to prevent it.

wow daming replies ah!Thanks a lot guys medyo may idea na ako ngayon.

Ewan ko nga ba kay ate yun kasi recommend ni papa kasi parang kakilala niya.At saka isa pa nga pala nabayaran na kasi yung engineer sa contract (parang 1 year ata yun) kahit di pa nasisimulan ang construction ng bahay.Kainis nga eh kasi ang dami nilang demands regarding sa building permits at kung ano2 pa at hanggang ngayon di pa nasisimulan.
Paano yun?Pwede pa bang bawiin yung bayad at maghire uli ng isang architect?

Thanks sa reply sir.May i know po ba what are the preventive ways na pwede para sa ganyang situation?

pasensya po s mga engineer.... im just asking me_here? not to offend or blame you mga ser

since semi circle ang magiging shape ng inside gutter mo dito, cguro i will suggest concrete inside gutter tapos use yung membrane type for the waterproofing,,,medyo mas mahala nga lang,,,

im sure meron pa dyan na may mas magandang suggestions!

do you mind posting the drawings? with dimensions if possible. if the area to be roofed is too small there might be a problem. let's see the drawing first.

this is the cad file of circular roof area. And the orig file and revised of the engineer.

looks like the engineer downgraded your expectations. from a mediterranean to a contemporary. he might be concerned about your budget.

some issues:
1. metal sheet roofing won't work for a small area like your stairwell. result will be unsightly stitching of roof panels to follow the circular shape of the stairwell. clay roofing tile may work but the stairwell should be much bigger (as in your ref image). bigger to an extent that the laying of the clay tiles will also be pleasant.
2. the engineer's proposal works structurally to accommodate the full height glass windows where the weight of the roof is imposed on the semi-circular beam probably anchored on columns or structural walls, unlike the reference image where dead loads are imposed on the round wall (or might have columns within).

if the construction have not commenced yet, you can insist to revamp the design until it meets your expectations (you are the client afterall-you have the right to reject). but be prepared to spend more coz clay roof cost a lot more than sheet metal, not to mention a more complex trusswork to form the shape of the roof. and if you really want the ref image to materialize, i suggest a bigger-grander stairwell coz it will look like trying hard with such a small area. with such an adjustment, the whole design will need to be relooked.

on the side, why the need for so many steps as you enter the house? (refer to the plan)

Thanks a lot for such a very helpful info sir ...How much will it cost kaya for that kind of roof and the whole circular area including the window?Kasi my sister also wanted to know how much the house will cost per square meter although meron naman siyang estimated cost.Baka kasi kulangin yung budget niya

you are welcome! sorry i won't be able to advise with regards to costing as i'm based in singapore. since you've already paid an initial sum to the engineer and he has the blueprint let him do the maths. but i really suggest you hire an architect to protect your interest.

baka nga talaga dahil sa budget ang problem bro.

GI longspan na tegula design cost around 700-1200 per sqm. depende sa thickness. ok din to kasi lightweight, kaso fake talaga kasi yero, pro depende din sa execution, baka kayang pagandahin.

Concrete Tiles/ Claytiles cost around 1,500 to 3,000 per sqm. Medyo mabigat, kaya more expenses din sa roof truss at mga accesories pa.

Kaya madami din talagang factors sa paggawa nito. good luck!

Ganun pala yun sir.Medyo nalilito na po ako pagdating sa mga budgets2 na yan.Pero po kasi ang estimated cost po ni ate per square meter dun sa bahay niya is 6,000PHP sa 1st floor then sa 2nd floor po is 8,000 per square meter.Di ko po alam eh kung kasama na roof doon.At medyo malaki2 rin ang first payment nila dun sa contractor na yun.Sa ganyang budget is it possible to achieve the desired plan?
Siyanga po pala mga sirs, babae po ako.

at meron pa po pala ako gustong iinquire kasi po sabi ni ate 84 blue prints po ang ginawa para po daw sa building permit.Medyo nashock po kami kasi po parang medyo marami lang siya.tama lang po ba yung 84 blueprints para dun sa pagawa ng bahay?
