Double garages are a common feature on many Downend properties, and their roofs - typically larger flat expanses than a single garage - are exactly the kind of structure EPDM rubber roofing was built for. It's a well-suited option, and understanding why can help if you're weighing it up against other coverings.
One of EPDM's practical advantages on a double garage roof is that the membrane can often be supplied in large sheets, sometimes covering the entire roof area in one piece with no joints at all, depending on the exact dimensions. On a roof of this size, minimising or eliminating seams significantly reduces the number of potential weak points compared with a material that requires multiple joints to cover the same area.
Double garage roofs in Downend are often more exposed than roofs closer to the main house, sometimes standing slightly apart from other structures with less shelter from surrounding buildings or trees. EPDM's strong resistance to UV exposure, temperature swings and driving rain makes it well suited to this kind of more exposed position, where a covering needs to perform reliably without the benefit of much shelter.
Garage roofs also often carry a certain amount of foot traffic during installation, maintenance, or if the garage roof is ever used to access other parts of the property, and EPDM's flexibility and durability generally cope well with this kind of occasional use, provided reasonable care is taken, compared with more brittle alternatives.
As with any flat roof, the falls and drainage need to be properly designed on a double garage roof, since a larger flat area means more water to direct efficiently towards outlets during heavy rain. Getting this right at installation avoids ponding water building up in the middle of the roof over time.
The condition of the roof deck matters just as much on a garage as on any other structure. Older garages in Downend sometimes have decking that's deteriorated over years of a failing felt covering, and this needs proper attention and repair before a new EPDM membrane is installed, to make sure the new roof performs as it should.
If the garage roof will also carry any additional load, such as solar panels or a roof light, it's worth mentioning this at the assessment stage, since it can affect how the membrane and any upstands are detailed. Planning for this upfront avoids complications later and ensures the finished roof performs exactly as intended.
Overall, EPDM's combination of durability, flexibility and minimal seams makes it a dependable, low-fuss choice for a structure that's often somewhat out of sight and out of mind.
