Flat roof woes


Guys I own a rental house with a flat membrain type roof.  It has mansoid sides and is two stories.  The existing roof is 8 years old.  It has several leaks.  I am going to sell the house shortly so I really don't want to change the roof.  What is the best way to have it repaired.  The leaks appear to be around A/C's and vents.

When I had my trailer, we used to use stuff called "Gold Bond" to seal cracks in the sealer of the flat roof. Here, it was sold at Home Hardware, a Canadian store, but maybe Lowes or Home Depot have it.

Hey Haffie, People use the word membrane to describe several types.

I will assume you have shingles on the steep sides and a very low slope top 2 sides. Good thing about that is it's nice and flat to work on.......just need a 2 story ladder to get up there.

Is it torch-applied membrane, EPDM (rubber, black), PVC (white) membrane or some other.

I hate to say it but a company specializing in flat roofs may need to be called. Low-slope roofs and membrane repairs are best done by people in the know. There are a few different PVC or Co-Polymer alloy roofs and repair procedures are different for each one. Repairs also must be made with the same like material.

Of course, on the bright side, it may only need some sealant but again, only certain sealants with certain products.

If there are leaks around vents on the shingles, that's just good ole roof mastic or Henry's or whatever black roof pucky stuff you want.

Where are you located??? I might be able to refer someone in the area but will need to know a little closer what product is actually up top.
A few pics would help alot. I know this is a froum to help out withinfo but this is one of those thing where I definitely need to see it.

Hope this helps, John

CHS thanks for the reply.  If I remember right, it was a black rubber type membraine.  The seams were heat sealed.  I am trying to find the roofer that installed the roof 8 years ago and have him repair the leaks, but most roofers don't seem to last 8 years.

Mello I agree.  Flat roofs are a pita.  The way the house is made it is almost impossible to change the style.  There are 2 AC units on the roof and a steel beam that supports half of the house.
I just want to sell it and get rid of it.

I can dig it - - - not worth the cost of a major restructuring is it???

I work for a commercial single-ply roofing company.
Being your roof is only 8 years old it's probably not a torch-down, most likely PVC or TPO.
It sounds to me like it was poorly installed as most single-ply roofs are usually good for 20+ years with a small amount of preventive maintenance.
If you can post a picture of your A/C unit curbs, I might have a suggestion. Could be that there was sealant/caulking used that has deteriorated and needs to be replaced.

By the way, there are two kinds of flat roofs.......those that leak and those that will leak! biggrin
