dc3driver 378 Posted May 18, 2013 Share Posted May 18, 2013 We have been out looking at houses & it seems almost all are metal roofs. We looked at 1 house, built by a foreinger that had a shingle roof. It looked like a lot of houses I have seen in the US. What would be the advantages or disavantages to a shingle roof here? Thanks.

Headshot 29,393 Posted May 18, 2013 Share Posted May 18, 2013 Disadvantages: More expensive More heat adsorbent (holds the heat longer) than metal roofing of the same color (especially if the metal roofing has a foil/foam underlayment) Must have plywood underneath which is susceptible to termite and mold damage More likely to be damaged in a typhoon since the wind can get a better "grip" and can tear out single or multiple shingles Takes longer to install and is more easily screwed up Lack of craftsmen who know how to properly build an asphalt shingle roof Advantages: The only advantage I can think of for having an asphalt shingle roof in Cebu is appearance if you like the look of shingles 1 Link to post Share on other sites
Knowdafish 1,772 Posted May 18, 2013 Share Posted May 18, 2013 What was the composition of the shingle roof you were looking at? There are shingle-looking roof materials available in the Philippines other than asphalt based. Some are reinforced plastic/fiberglass, while others are steel. Some look cheap and cheesy while others look quite good, at least while looking at them from ground level. In the U.S. shingle type roofs are most often asphalt based but also come in concrete, slate, and steel, among others. Here I have seen steel, reinforced plastic,concrete tile and non-reinforced plastic, but not asphalt. As mentioned before, I think all shingle roofs need need a strong and heavy backing, which I would assume to be plywood which is a potential problem. Steel vvv Link to post Share on other sites

A tip, if you are very curious, take a small pair of binoculars. They work out well for checking out a roof, even a second story one, from ground level. Link to post Share on other sites

Like the lookand want something more unique then the metal style or just wondering if theirs any benefits? Edited May 18, 2013 by Dolsos Link to post Share on other sites
dc3driver 378 Posted May 18, 2013 Author Share Posted May 18, 2013 (edited) I'm not interested in shingles in themselves. It is just that a house I looked at had them & I haven't seen a house here with shingles here before. Seems not to be common. Edited May 18, 2013 by dc3driver Link to post Share on other sites
SkyMan 24,401 Posted May 18, 2013 Share Posted May 18, 2013 Advantages:Much quieter in the rain than metal. These: handle the wind much better than the traditional like these: Link to post Share on other sites
Headshot 29,393 Posted May 18, 2013 Share Posted May 18, 2013 (edited) Here is the color scheme I am using on my house (this isn't my house...but I will also be using stucco and moldings in the same colors. The big thing on the picture, though, is the roof. This is how my roof will look (even the same color). My roof will be a simple hip roof, with no gable ends, so there is less for strong winds to catch. This is a metal roof. Click the picture to make it bigger, so you can see more detail.

Knowdafish 1,772 Posted May 18, 2013 Share Posted May 18, 2013 (edited) Sharp look! (pictured above) I am curious though, why do most houses here go with a dark colored roof (blue, red, brown, green, medium-gray) which gets VERY hot versus a cooler color like light blue or white.

As long as you use the foil covered insulation under the steel sheeting, and vent the roof properly, it really doesn't make that much difference what the roof color is. I will have an exhaust fan in the roof (near the peak on the back side) to pull hot air out of the attic area if it builds up. Link to post Share on other sites

I will have an exhaust fan in the roof (near the peak on the back side) to pull hot air out of the attic area if it builds up. Exhaust fans are great, but color makes a HUGE difference--White repels and dark attracts. Touch a dark colored car in the sun and touch a white one. My builder has been in the business for many years and he is amazed at the difference now that he has been inside our house on hot days.! 1st white roof he has ever installed-white galvelume with 2 coats of Boysen Laguna White roofguard. Too late now, but I wish we would have had a hip roof instead of gable, but too late now. Plus side, it sure does help with the cooling. We also did the necessary work in attic so it would be easy to add 2nd floor if we ever desire. 4 Link to post Share on other sites
Headshot 29,393 Posted May 19, 2013 Share Posted May 19, 2013 I have a white truck. It is hotter than Hell if it has been left out in the sun. Oh...and you can burn yourself on that cool surface. Link to post Share on other sites

Aren't there special solar reflective paints? I thought I had heard of them a while back, maybe thats what he meant? I'd still like to cover my roof in photovoltic panels and run some big ass ac's.

Headshot 29,393 Posted May 19, 2013 Share Posted May 19, 2013 (edited) I believe the key to house cooling is in insulation and setting up adequate convection currents in the attic. If you can set up air flow where cool air is being pulled in through vents in the eaves, and heated air is escaping through vents high in the roof, then the attic area will remain close to the outside temperature. I will add a fan to that passive system to help if the self ventilation falls behind, but that shouldn't be very often. Now, it is possible to coat your roof with coatings than will prevent adsorption of heat, or you can simply insulate against that heat. I don't particularly care for the look of a white roof. It reminds me of the crap they put on mobile homes to reseal the roofs. So...for me it is partially an aesthetic question. http://www.mrinspector.net/mutual-resources-psds/Attic_ventilation.pdf http://www.nrca.net/consumer/attic_ventilation/passive.aspx I also believe that it is extremely important that you adequately insulate the area just above your top floor (living space). If I ever decide to build in living space into my attic, then I will put insulation in the roof trusses, but for now, my main insulation layer will be below the attic (and above my second floor). I will also have the roll-type foil-backed foam insulation just under the roof sheeting Therefore, I believe that if you set up adequate convection currents in conjunction with proper insulation, you really don't need to worry too much about roof color. You can choose the roof color that looks good to you. Edited May 20, 2013 by Headshot Link to post Share on other sites
