SolarFlash® installation on plain tile roofs


SolarFlash® installation on plain tile roofs

Description: The SolarFlash® system is a simple and effective waterproof solution to refitting roofing slates or tiles around a roof bracket when installing solar photovoltaic, or other, panels. By installing with SolarFlash®, it can help you to ensure that all your installations are MCS 012 compliant.

SolarFlash® is very easy to install and enables you to do an excellent job and leave the roof with a clean, reliable, and weatherproof finish, without any additional expert knowledge or training. Our installation video shows you step-by-step how to easily and quickly install SolarFlash®.

SolarFlash® is in use all over the UK as well as in a growing number of countries. It is used by solar installers, housing associations, roofers and developers.

Why you need SolarFlash®

The existing method of dressing a flashing material around the bracket is fundamentally flawed, as the bracket moves and in doing so can move the flashing material, which can potentially lead to damaged or cracked slates.

This impacts the weathertightness of the roof and means that the installation is not MCS 012 compliant.



When an installer approaches an existing roof they’ve often got a fear of where’s that rafter going to be. I’ll explain why it doesn’t matter with our method. You’ll usually find every fifth tile is nailed. If you need to get a nailed course out, take to a drip of it and you can access the nails.

This rafter is in position A, where it’s between these two tiles. We’ll explain further. We’ve designed this bracket specifically for plain tiles, often called rolls. What’s important about it is it has two fixing points: one through the rafter, one through the batten, through the rafter. But this is what’s critical: this elbow has to come from the bottom of the batten because of the length of these tiles.

If the elbow came from the top of the batten, you end up having three courses of tiles to cut. With this, you have to show you how it works. The positions of the bracket and the rafter are the same as with slates. There can only be three different positions in relation to this course of tiles or slates, whatever you’re using. This is position A between those two slates; position B in the middle of this slate; and this is position C between those two points.

If a rafter is to be put anywhere else, it would be in one of those positions in relation to another tile. So you will always have the same group of cuts. You’ll need this clearance and you need this angle to get away from the thickness of this tile. So, we have position A. As with a slate, it’s 1 under and 2 over. Now, it wouldn’t be practical to use this. You use that as one under. You might get away with it, it might be strong enough, but if they broke, the tile comes out. But that is impractical for that one. What you would do is you put the full tile in, mark it with an angle grinder, cut the bottom off, then you end up with this. That’s one under, form on solar flash on, do over it. The solar flash comes up to here, the next tile comes down to here.

Position B: it’s 2 over, 1 under. Solar flash on. Now, this one over, even though this is as flimsy as the other one, if they broke off, the roof is still intact. They would come down the roof or you could leave them on. It leaves a better-looking job. If you wanted to, you could just use that or you could put a piece of tile behind it. The only difference it makes is you can see some extra solar flash. It’s still going to be waterproof. This last one, position C, is between position A and position D. It’s in the center. You have one cut, then dip, fall on solar flash on, one over, and then a full tile to finish it up.

So no matter where you open the roof up, no matter where the rafter is, it will always be one of these three sets of cuts. This is one under, two over. This is two under, one over. This is one under, one over. So wherever you open the roof up, it should take you five minutes to put a bracket using this method and this material. It’s a guaranteed waterproof aesthetic finish that will leave your customer happy.
