Can You Replace a Flat Roof in Winter?

Flat Roof Replacement Baltimore

In a word, yes. If your Baltimore area home has a flat roof that’s seen better days or has sprung a leak, you don’t have to wait until spring to replace it. But you will want to work with a roofing contractor experienced in flat roof replacement in cold conditions (under 40 degrees).

That’s because the not all flat roof materials are suitable for a winter roof installation. If you think you need a new roof, the first thing to do would be to call us to do a roof inspection. We may be able to make temporary roof repairs that can last you until spring, but we can also complete a flat roof replacement in winter if necessary.

If there is snow or ice on your existing roof, that will need to be cleared in order to get a good look at the situation. And then the roof would need to air dry before we made any repairs. If we are replacing your roof, we would begin tearing off the old roof as soon as the snow and ice was cleared.

Flat Roof Materials for Winter Installation

While there are 4 basic flat roof systems, only two of them can be safely installed in winter – TPO and PVC. The other systems (EPDM and Modified Bitumen) use adhesives that can freeze, causing premature failure of your roof, and voiding any manufacturer’s warranties.

TPO and PVC, on the other hand, are thermoplastic flat roofing products, which we install mechanically, using plates and heavy-duty screws. We then use Hot Air welding equipment to seal the seams. This equipment uses high temperatures (800-1,000 degrees F.), ensuring the seams will not be affected by the cold.

TPO Roofing

TPO is short for thermoplastic polyolefin. It’s a single-ply white roofing membrane suitable for use in both commercial and residential applications. It reflects the sun’s rays, which can keep buildings cooler in the summer. When it’s installed properly, a TPO roof will last about 25 years.

PVC Roofing

PVC is short for polyvinyl chloride, which is made from processed petroleum. Like the TPO membrane, the PVC membrane is also white and has the same heat-reflecting quality. PVC is slightly more flexible than TPO and has been in use longer. When it’s installed correctly, a PVC flat roof should last approximately 20 years.
