House Constuction [Merged]

Problema nyan is village restrictions, here, we are allowed to choose from 6 colors only, bawal pa ang pareho magkatabi and white is not in the choices. With regards to roof, we are required to use asphalt shingles, wala ring white nito hehe

Gusto ko rin sana asphalt shingles kasi maganda tingnan but nung nalaman ko na poor performance pala sya sa hot climates, metal long span na lang pinalagay namin.

Shingles poor in the tropics? Where did you hear that, sir? They don't corrode & when installed to factory specs, they hold the factory material warranty assigned to that particular variant, 20/30/50years....
I've seen metal roofs suffer way more typhoon damage than properly applied asphalt shingles. These are the reasons why top tropical resorts specify them.
Again, key here is to strictly follow the minimum roof slope, the proper underlay material & thickness, the proper moisture barrier, & the correct proportion of ridge ventilation. Improper install, cost/short-cutting may have given this type of roofing the false negative impression.
Amongst the available notable brands we've tried, IKO from North America has been the most consistent. Guess, them being the lone vertical roofing & waterproofing conglomerate got its pluses. Even IKO's granules are produced in-house. Owens & Certainteed outsource their raw materials from 3M & other companies. Some of their lines come from different plants, too. Consistency of batches over time come into play when the roofing will require sectional repairs or overlay.
Where metal roofs have the advantage over shingles? The latter requires a high minimum slope of 15°. Shingles can't do flat roofs. And, where you have a secondary & lower shingled roof, avoid it used as a relay to heavy water volume from roof valleys above them to avoid visible wear patches long term. Those said valleys above lower roofs, we normally apply selective sectional welded stainless gutters.
Roofing material choice(shingles/tiles/metal) is usually dictated by application, design intention & cost. When properly done, all these can perform to expectations.

Our previous architect told us that asphalt shingles hold more heat than GI sheets which reflect some of the heat, so went with that. We also have hidden roofs and just a small area can be seen so roof aesthetics were a small factor.
Sana pala ikaw na lang contractor namin hehe
Good thing youre here in the boards to give excellent advices![emoji1360]

No argument re heat retention & how colors & materials play a role in heat reflectivity. That's where the compensating components come in. Insulation & roof venting.
The various types of roofing have their respective pluses & minuses. Terracotta would've been ideal & great here, but are often shunned due to the cost of having them above our heads. And neither can clay do flat roofs. The added costs don't stop at roof quotes....Being in the tropics w/ a ton of rainfall, these need an added layer of metal undersheathing to get em watertight. Plus, the much higher density of clay requires beefier structural components that would continue down to the foundation.
Where susceptibility to corrosion isn't a factor, a good insulated thicker gauged metal roofing provides an ideal balance of function & cost. Now, pretty....that's what the designers are paid to do.[emoji4]
Me, just blessed to have had chances here & there to touch & test 1st hand them materials I personally can't afford. Every project provides valuable lessons w/ time's aid. I humbly deem sharing a pledge & duty to spare anyone from redundant, costly & proven mistakes.[emoji120]

Yung pang waterproof ba ng swimming pool ok ipang waterproof sa firewall? And what's it called?

May nakausap kasi ako regarding sa pagpapa-waterproof ng isang firewall namin. He recommended something that's supposedly used for swimming pools. Costs 5k per 4-gallon bucket but he couldn't remember what it's called.

Check w/ Sika, they've a number of options. Crack Isolation Membrane(viscous liquid form), & Cementitious waterproofing among them. Unlike pool conditions where concrete won't be dehydrated nor be subjected to constant significant thermal fluctualtions due to them holding water, firewalls will require periodic attention/reapplication.
Should you want a permanent solution where possible, go for longspan prepainted roof sheets installed vertically onto your firewall. Make sure to overlay a good flashing layer to cover the area where the wall meets the roof.

Is there an aesthetically better way of permanently waterproofing walls?

Yup, depends on the look you're after. Opaque Graphicote Glass or Aluminum Cladding are a couple & are pricier, but INFERIOR to longspan ribbed metal roofing for the application. Why? Those 2 rely on sealants which have lifespans shorter than the material they seal.
If you prefer retaining the look of concrete/masonry, there's a nonDIY system...EIFS. Pleko, Dryvit, Parex, LaHabra are some of the brands.

An advantage of using long span for walls is one contractor will do the roof flashing along with the walls and roof. He can also do the waterproofing. Less pointing fingers in case of issues. I believe the long span roof flashing also requires sealants such as Sikasil G8.

But it will look out of place in residential applications. Actually ACP will also look out of place.

What we do for new construction is use an admixture for the plaster such as Sika 1. We also use it for walls without ledges above.
