Dry Verges are becoming more and more popular on roofs. This is both because of updated building recommendations as well as the prohibitive cost of maintaining old mortar. However, some people who are considering taking up dry verge might be put off by how expensive it seems to be.
However, often dry verge can be significantly less expensive than we think. This handy article will take you through how much it costs to buy a dry verge for your whole roof.
Counting Courses
Before you even consider dry verge you should look at how many gables your house has. A gable refers to where a tiled roof suddenly ends to the sides of the tiles. If two sides of a roof meet that is called a hip, not a verge. If your house has no gables then it will not need dry verge, but dry hip instead.
However, if you do have gables, this means that you can benefit from dry verge. You will then need to examine your roof and count how many courses of tiles there are on one side. A course of tiles just means a single horizontal line of tiles. This is important since dry verge pieces will fit just over on one side of their own course.
Once you have counted courses, multiply that number by the number of gables you have on your house. The final answer is the number of dry verge pieces you will need. You will also need one starter unit per verge and one end cap for every pair of verges. Some dry verges are ambidextrous and use any piece for any side, but some are not and require you to buy half in a “right hand” variation and half in a “left hand variation”.
Calculating Dry Verge Costs
Once you have discovered how many verge pieces you need, then you can move on to calculating costs. Simply select one of our main dry verge brands – like Easy Trim, Klober or Timloc. Then add the cost of your starter units and end caps, then how many starter units you need. Often we offer bulk discounts on our verge pieces so even if you have a bigger roof there’s no reason not to install dry verge.
For instance, imagine if I was installing an Easy Trim dry verge on a house with 20 courses of tiles on each side of the roof. The roof has four verges. So I would purchase four starter units, two end caps and 80 pieces of dry verge. This total would run me to £23.96 for the starter units, £9.98 for the end caps, and £111.20 for the verge pieces, allowing me to assemble all the pieces I would need for a dry verge of my entire for the low, low price of £145.14.
