Roof verges: Do I repoint or go for plastic dry verges?

If your roof verges are in need of some maintenance, you might be wondering whether to repoint them or whether to instead opt for plastic dry verges. Plastic dry verge systems cover the joint between your roof tiles and brickwork without the use of traditional mortar.

Here, we’ll look at the differences between them to help you make the right decision for you.

Repointing versus plastic dry verges

Here are the main factors you’ll need to bear in mind when choosing between the two.

• Cost. Repointing will initially be cheaper than installing plastic dry verges. However, it will require more maintenance so will typically be more expensive in the long run
• Durability. Dry verge systems will last for at least 10 years. In contrast, mortar is less durable and can crack and dislodge due to natural movement and bad weather
• Maintenance. Dry verge systems are pretty much maintenance-free. On the other hand, when traditional mortar verges get damaged, this can give rise to problems like roof leaks and birds nesting
• Protection. If installed well, plastic verges offer more protection to the joint between your roof and walls. However, if they don’t fit correctly, they can come off in high winds
• Suitability. Not all types of roof tiles are suitable for plastic verges. For instance, slate roofs can’t have a dry verge system fitted
• Appearance. Dry verge systems can look neater than traditional mortar verges and will continue to look slick and new for longer. That said, some people dislike their plastic appearance and prefer a more traditional finish

Should I repoint or go for plastic dry verges?

When it comes to choosing whether to repoint or opt for plastic dry verges, there’s no one right answer. However, it’s worth noting that plastic dry verges are more durable, offer greater protection, and are virtually maintenance-free.

While the dry verge cost may initially be higher than the cost of repointing a traditional mortar verge, they’ll usually be cheaper in the long run. This is because you can expect to repoint a mortar verge two or three times during the lifespan of a plastic dry verge, which will usually last at least 10 years.

Find a roofer

Some roofers will offer both repointing and dry verge systems. If you’re still unsure which to go for, why not ask for their opinion? Not only will they be able to give you advice that’s bespoke to your roof, but a good roofer will also be able to complete the job to a high standard for you once you’ve made your choice.
