Question Rolled asphalt roofing?

Hi,
I need to get an addition on my house re-roofed soon.It measures 15ft x13ft.
it currently has rolled asphalt roofing on it,its old and wind damaged.
This roof slopes about 15-20 inches over 15ft.The rolled roofing seemed o:k,but didn't seem to last long compared to tab shingles???
I wondered what your thoughts were on doing a rubber roof on this instead?
Is a rubber roof cheaper?will it stand up better?I live in Mass.
Also can you tell me how much rolled roofing I need to buy for this roof?Also whats the difference bettween single and double rolled roofing?Thanks.
Iam trying to figure the cost of the materials first.Thanks

Rubber is great. Rolled roofing is cheaper. 60 mil reinforced EPDM is about $.65/sq ft. You will also need glue or their mechanically fastened hardware. Any roofing material supplier has this in stock. The rolled roofing comes in 100 sq ft (net) rolls. Actually 108 sq ft. Never heard of "single or double". Might mean a 2-ply vs. 1-ply system. 2-ply rolled roofing requires twice as much material and uses an 18" lap, instead of 3 1/2".

My father has some modified torch down roofs still holding up close to 30 years later. Of the hundred or so roofs he's done with torch down he's had no leaks. The material is basically a shingle in a roll which is very thick and durable. The rolls are 1 sq and very heavy. I've helped him on about 10 roofs with this method and they all turned out very good. There are six colors to choose from but I would not consider it a do it your self job. You have to torch down the roofing to a base sheet.

I've seen guys do TPO and Duralast flat roofs and thought to myself the roofing was very thin and wouldn't hold up for over 20 years.

1 or 2 ply?

so you would stick with the traditional methods I take it. I heard that torch down could be installed 3 layers thick as in base + center + top.

Flat roofing (low slope)

The slope on your roof is good for a self adhering modified bitumen with colored granules to match shingles.
They need a special base sheet.
Certainteed, GAF make good materials. Granules hold snow on roof so that it doesn't fall over thew edge.
On EPDM, TPO or PVC are smooth and the slope of the roof allows snow to slide off of it. Gutters will be torn off. Plants, hvac units and pedestrians are not good to have below the roof edge in the winter.

Torch down and Comfort Seal

A fellow installed a torchdown roof on my triple wide mobile home in Florida five years ago. Holding up with no problem. Color is grey.

I was wanting to cover with white Comfort Seal for a better appearance and also to reflect some heat away in the summer.

Now I was told by another party the torchdown needed to breath and to cover it would not be wise! Anyone familiar with this situation?

It would seem to me the Comfort Seal would be added protection. Thanks

I have not heard that a torch on needs to breath but before installing ANY coatings, you should call the manufacturer. You may have some compatibility issues.

Rubber Is Better

Ive Been Doing Rubber Roofs And The One Thing I Can Say Is If Your Roof Is That Size Your Better Off Going Rubber It Can Last Alot Longer Then Rolled Roofing And 1,000 Would Probally Do It
