Your new RUBBER roof !!! 😉

Went to Worldbex in Manila last week.
Partly was looking for something to seal my 220sqm cement flat roof.

In the past I've thought about:

- Flame sealing: only as good as installation
- More elastomeric: seems to last 2 seasons at best

But I found a kiosk at Worldbex run by Ames... They seem to have a really cool rubber based product:

1. Scrape off bubbles, loose paint
2. Apply their primer
3. Apply seam tape both inner / outer corners and over joists that may hairline crack
4. Apply multiple coats of their super elasto-barrier (it's a thick gray rubber)
5. Apply a coat of their Maximum Stretch (white rubber to reflect sun)

It's NOT a cheap alternative - but I saw some of the rubber samples - 3 - 5 coats feels and stretches just like a wheel inner-tube. They say it's even good for pooling areas - since it creates a seamless rubber sheet.

If part of the roof is going to be used for hanging out on - they have a liquid granite you apply with a trowel on top - sort of felt like a hard plastic.

Has anyone had any experience with this product? Seems too good to be true!

I have a few low areas that tend to pool - any advice how to raise them up prior to application? just scrape the paint off use more cement?

Re: Your new RUBBER roof !!! 😉

This is very interesting bro ghost, thanks a lot for sharing this as this will be very useful since most new houses constructed now a days are opting for roof decks due to the changing times and weather patterns like continuous rains that causes flooding.

Oh by the way were you able to ask how much per can of its components , the sealing tape, the primer and the final rubberized coating ??? :p

Thanks again for sharing !!! 😉

Re: Your new RUBBER roof !!! 😉

it appears to be a really good system - they will write you back the same day (so far) i sent photos of my roof, and dimensions and they did all the leg work for me.

the idea of a seamless rubber roof is truly awesome. this is what we all want, right? an innertube that stretches across the entire roof and up the sides.

Again it's pricey - you can look on their site to see what the prices are in USD. it appears to be about $150 usd per 5 gallon tin. in my case I need 30 tins (OUCH). But that's primer, gray, and white. What does a tin of Boysen go for these days?

Still - with elastomeric - it just doesn't seem to last more than two seasons on my roof. the cost of getting people out every two years, putting down 3 additional coats of boysen etc - probably will break about even. IF their product truly delivers.

right now checking on prices from MNL or direct shipment. will update.

from our emails:

(me): How do i know when the product has reached the end of it's life cycle - will it flake like elastomeric? How do i remove to re-apply.
(them): As long as you keep it maintain it can last as long as the roof. If you begin to see any of the grey color Super Elasto Barrier then maintenance coat(s) should be applied

(me): Do the number of coats add additional 'years' - meaning if i use 5 undercoats will it last for 10 years, vs 3 undercoats for 5yrs?
(them): You typically get 1-3 years per coat. For a full coat system I suggest maintenance coats every 7-10 years. If the water ponds maintenance on those areas may be needed sooner as needed.

Concrete may seem stiff and solid but actually it bends and expands in reaction to changes in temperature.

You may be able to apply a perfectly flat surface at a particular time of the day but it won't be the same flat surface at noontime or in the evening.

If the pooling are acceptable now, let them be.

Is the roof leaking presently?

With the fantastic cost of the rubber compound, I would consider an asphalt based solution covered with a shallow layer of soil - instant roof garden 🙂

Ewan ko kung buhay pa yung garden ng SM North Edsa sa level 2 nya. I was impressed when I last saw it.

I haven't checked the price locally yet - from the manufacturer I'm looking at 225,000p for all three layers of the rubber compound (about 30 tins (5 gallon)) - that includes shipping - but not customs.

so yeah - expensive. however, over 10 years 25k a year - not a crazy amount more than repainting over and over.

yes i have some hairline cracks that drip water, mostly from the joists where the walls meet the roof, one or two around the drains... i've filled them with compound for now and no more leaks with the occasional rain we've been having.

interested in your idea of soil - by adding soil / grass are you saying that i would avoid the pooling water (grass suck it up) and have less chance of leaks? would be pretty cool to mow my roof. lol - i've got some brochures for the roof garden companies - most of them show a layer of 'something' beneath their soil/mixture - but none go on to explain what this waterproofing layer is. how deep would you make the soil? wouldn't that facilitate a constantly moist / wet roof required to keep that grass green?

i'm at a loss really - of what to do - i can probably get by this upcoming season with compound / vulcaseal but really should take care of the problem now.

The grass sucking up the pooling water is only one bit of advantage of a roof garden. Major ones include:
1. Greater thermal insulation for the space being covered.
2. Environment friendly in producing oxygen and not reflecting back the sun's rays to the atmosphere (thus warming it even further) compared with a white or tiled finish.
3. Potential of growing decorative flowers or herbs for cooking.
4. Much more aesthetic than tiles when used with garden furniture.
5. One item to boast to visiting family and friends.

I understand you are still in the process of "collating" the various possibilities your existing roof can potentially be.

It may be helpful for us "usiseros" some background from you on the story behind the concrete roof. What was your initial intention in its design and construction.

Keeping the grass and other plants healthy comes with the package. That can be either torture or therapy. It depends on the kind of person you are.

Of course you can always hire someone to do the regular upkeep of the garden.

Garden design is a specialty in itself. It should suit the needs and desires of the owner.
