I have a flat roof with shingles. I am planning to change to a epdm rubber roof. I have spoken with two contractors one says that the shingles need to come off and the other says that they don't. Who is right and what is my best option. I plan on living here for quite a while. Any info would be gladly appreciated.

It is always 'best' to remove existing shingles so that the roof deck can be inspected for structural problems and repaired, but it is often not 'necessary' to remove existing shingles.

So long as there are not already more than two layers of roofing AND so long as there does not appear to be any sheathing or rafter under the shingles, there is no reason to remove the shingles to install the edpm roof.

I wanted to provide some clarification and additional information on the issue of installing an rubber roof cover over an existing shingled roof.

Firstly, the homeowner mentioned that the roof was considered at flat-roof, which would imply a slope of less than 2/12 (two inches of slope within a twelve inch run). If this is true, then conventional three-tab roof shingles should not have been used initially. Three-tab shingles are not approved for roofs with a slope of less than 2/12.

Secondly, rubber roof covers should always be installed in solid roof decking. Either plywood, OSB sheathing or other acceptable substrate must be provuded. The manufacturer of the rubber roof material will not honor any warantee associated with their products if the roof materials are not installed to all the required specifications.

Lastly, it is highly recommended that rubber roof installations only be preformed by a licensed or certified roofing contractor. In the absence of such licensing requirements (many cities do not require licesure of roofing contractors) then a verified list of references should be obtained from all prospective installers.

Specific installation requirements for each manufacturer's rubber roof systems can be obtained online or by directly contacting the manufacturer. It is always recommened that a building owner conduct background research independently to ensure a satisfactory outcome to any construction project.

I had a "flat roof". I asked the contractor to only put the rubber roof on. I took the old off and checked the plywood underneath. A couple pieces needed to be replaced. When I opened it up I also found the insulation had gotten wet and needed to be replaced which could not be done from the attic which was too small.

You may want to do the removal yourself and save yourself a little money. Don't forget ventilation.

Good luck,

"The manufacturer of the rubber roof material will not honor any warantee associated with their products if the roof materials are not installed to all the required specifications."

Rubber roof manufacturers do not normally warrant application of their products on residential roofs anyhow...so what is your point?

Rubber roofs are COMMERCIAL products and warranted ONLY if the product is applied over a commercial structure.

Rubber roof manufactures offer NO warranties whatsover for roofs applied to residential structures.

Any warranty you may have for a rubber roof is offered soley by the installer, not the manufacturer.

Also, a rubber roof 'may' be properly installed directly over a shingled roof without removal providing that the shingles and base sheathing are sound AND the rubber membrane is applied over and additional layer of approved substrate applied directly over the shingles.
