My Flat roof project-help!
 
Hi everyone my first major post. been reading for hours about roofs here. I got a old tar and gravel flat roof and a steeper shingled roof right now. the roof is leaking badly on the gravel side.

So i got a couple different bids. but i need help deciding whats the best option:

1-johns manville granular APP mod bit. $5k

2. firestone epdm. $7k

3. pvc $18k (yikes)

for all the experts out there ( ed, TRG, etc) which option do you think is best? i think at this point i am going to tear off the existing shingle roof and replace with whatever material i decide to go with.

also, how do i insure the roofer i pick is legit? i asked for references and insurance, but what else? thanks for all the help!!!!

Don't know what state you are in. I can tell you in Washington you can go to the state's Dept of Labor and get all pertinent info on a contractor. License, insurance, bond, lawsuits, tax status. In Idaho it's not nearly as detailed. So it varies from state to state.

As for the type of roof, you'll be lucky to get 10 years out of the APP. The EPDM all depends on what material and who is installing it. Same as the PVC. Honestly, the best system you could put on (besides low-slope metal) is what's not on your list but is already on your roof. A 4-ply gravel BUR is good for 25-30 years properly maintained. Unfortunately not many people do them anymore. They learn how to do single-ply and call themselves roofers.

I must say the PVC price does seem inordinately high compared to the epdm but I don't know what either plans on doing. It does look like you definitely need something done though. What is the square footage of the deck in question?

I'd go with EPDM, but whether it leaks or not is all up to how it is put on, and I wouldn't replace the shingles with EPDM just the flat part of the roof then just get some new shingles for the rest.

Have you considered a standing seam metal roof?

federer 08-21-2010 08:09 PM

thanks for the input gentlemen. yea BUR is old school and noones proposed it. noone proposed metal either. i have read up on everything system except metal. is there a big advantage to using metal? i mentioned replacing the shingles side too because 2 squares need to be fixed on the shingle roof as well. something is pushing up from underneath and causing it to push up through the roof.

oh and i am in the DC metro area. we had the crazy insane crazyyyyyyyyy blizzard you guys prob heard about

A high-end standing seam metal like Imetco Series300 is your best option. May cost a little more up front but, properly installed, you will never have to worry about it again. I'm not talking about something you buy from the big box, Series 300 is a very well-engineered system and worth the money.

You still never told us how large the area in question is.

thanks for the reply. i need to research into metal. the flat slope side is about 750 sq ft, and the shingle side is a little less maybe 700.

So the prices you listed are for an 8 square job? Wow, what else is being done besides tearing off existing and installing a new roofing system? Or is this for the entire house?

I would hope you will close in and get rid of what’s left of that window in the process.

I'm pretty sure thats the neighbors house.

:laughing: Ok I'll shut up. :drink:

I have see that before though. :wink:

federer 08-22-2010 10:41 PM

so the best way is to call the manufacturer of the roof you want and ask them whos qualified to install the roofing system they make
