my old roof starting blowing away!


Hi, i have an older maybe 60 yr. old custom cape cod with big dormer. Above the dormer the roofing material started to blow away last night after heavy winds. My father in law called the material cold roll or something like that. It looks like wide, maybe 2 ft. heavy roofing rolls layed down. Anyway, the roof is in bad shape and needs replaced. Also, the pitch isn't steep at all, and it is easy access to this roof, i just climb out my window and small ladder up. Probably measures about 20x15 ft., somewhere around 300 sq. ft.

I am thinking about replacing with a rubber roof, what do you guys think?

EPDM
TPO
Torchon
Self Adhered Mod

Lots of options for that type of structure.
Check out ABC Supply and look at their Low Slope roofing systems and find the one you feel best about.

What you have is what we call 90 LB mineral roll. Some people call it roll roofing, however with so many products coming on rolls we prefer not to use such a generic term. It's really a cheap roof covering.

My advice would be to tear of your roof. Always tear of the roof IMO. Then the type of roof you installc an vary greatly. I even think, from the pics you posted, that the roof is adequate enough for shingles. The manufacturers would likely have additional underlayment requirements such as double layer of 15# felt or entire coverage of ice shield. The other option is a low slope roofing membrane.

If you intend to do this project yourself, my only advuce is self adhering modified bitumen. CertainTeed makes a product called flintastic SA. THis is rated anywhere from 12-20 years and I highly encourage you go with the 20 year spec.

TPO is currently my preferred low slope membrane of choice, however I prefer not install it on a residential project such as yours for one reason... it's look. The roof will be visible from the ground, and most people won't like the look of a pure white roof. There are some products that have a pattern printed on the tpo membrane, but I haven't used them yet.

Is this something you intend to do yourself? If you intend to hire a professional roofing contractor I suggest you read these two articles first... http://reliableamerican.us/articles/...contractor.htm http://reliableamerican.us/articles/...questions.html Oh heck one more... http://reliableamerican.us/articles/...a-shingle.html

Hi Grumpy, i guess 1 good thing is that this roof is not visible from ground level. It is a small 20 x 15 ft. roof. It is a slight pitch, just wondering if shingles will do the job. There is an air vent to deal with on top too. It would be nice if i could do it myself, i am pretty handy, just never did a roof job. How much would applying a rubber roof be ballpark for a trained pro.? Or what would be my options for DIY? Thanks

Shingles are good down to 3/12, some manufacturers allow 2/12. However at those slopes you either need to double up your felt or do entire coverage with ice shield. Having said that, you're probably better off with a low slope membrane.

If there is an air vent, meaning exhaust ventilation, then you want to get yourself a one way breather vent, look into portals plus. please do yourself a favor and not use a shingle style vent on a flat roof.


If you are going to do this yourself, do yourself another favor and order the installation manual and video from which ever manufacturer you choose. If you are going to do it DIY, I suggest a self adhering modified bitumen like CertainTeed Flintastic.

As for a ball park, that's a hard one. It depends on the roof type you wish to put back. Also pricing varies regionally. You'd be looking at 2 guys a full day plus materials and disposal. Around here if I were to install that little roof, you'd be looking at $1,750-$2,500 complete. There'd be no doubt that you could find a "handy man" in my area to do it for half that, but insurance and running a legitimate roofing company costs money.
