Moss Prevention - Copper and Zinc Strips

22nd January 2021

At this time of year, damp can be a problem in even the most well-ventilated homes. Aside from the most well-known causes of damp, moss can contribute to the problem by acting as a sponge which soaks water into the structure of a building.

When it comes to maintaining the condition and value of your home, prevention is very often better than cure. And that is most certainly the case when it comes to moss growth. When placed just below the roof ridge, zinc and copper strips can prevent the growth of moss and algae. Here’s what you need to know.

How do copper and zinc strips prevent the build-up of moss?

Moss grows anywhere that is shady and has access to moisture. Grass, fences, roofs; especially if they are north-facing or shaded by trees. The use of zinc or copper strips inhibits moss growth by releasing particles of the metal onto the roof with rainwater.

Do copper and zinc strips work on thick moss?

The strips are effective at inhibiting growth, but they do not eradicate moss and algae altogether. As the strips are dependent on the run-off of rain from the roof apex downwards, the concentration of metal compounds reduces with the flow of water. As a result, zinc and copper strips may prevent moss at the top of the roof, but could be less effective in the lower parts. That’s not to say that they are not worth using; it is much easier to remove moss from the lower areas than the top ridges.

How should I install copper and zinc strips?

Zinc or copper strips are most effective when they are installed when a home is built, or a new roof is installed. If you are looking at getting your roof replaced or repaired, speak to your roofer about moss-prevention. If fitted retrospectively, it is important to make sure that all moss and algae is removed before the strips are fitted below the roof ridge.

How else can I prevent moss?

Aside from regularly removing moss and installing zinc or copper strips, you can help to reduce moss growth by removing the factors contributing to it, such as cutting back overhanging trees and branches. If you are looking for a long-term solution, you may consider investing in tile coating, which weatherproofs your tiles and prevents moss and algae growth.

Do I need planning permission for a home extension?

Plenty of extensions don't need planning permission - they fall under Permitted Development. Whether yours qualifies depends on the size, location, and type of build. Single-storey rear extensions up to four metres on a detached house often get the green light, but side extensions, two-storey builds, and properties in conservation areas usually do need permission. Always check with your local planning authority before you start - building without the right approvals can mean being made to undo it all.
What is involved in building a conservatory?

You're looking at groundworks and foundations, the frame and glazing, the roof, and then the internal fit-out - flooring, heating, electrics. Most conservatories under a certain size fall under Permitted Development, but they still need to comply with Building Regulations, especially if you want to use the space as a proper room year-round. On the roof: solid or tiled options make a huge difference to usability - traditional polycarbonate can be unbearably hot in summer and freezing in winter. Most projects take two to six weeks.
Do I need a structural engineer for my home renovation?

Not for everything - but if structural changes are involved, yes. Removing a load-bearing wall, putting in a steel beam, touching the roof structure, or adding a sizeable extension all need a structural engineer to design the solution and produce the calculations for Building Regulations approval. A builder might tell you whether a wall is load-bearing, but only a structural engineer can specify the right beam and carry professional liability for that advice.
Do I need planning permission to install patio doors?

Usually not, if you're replacing an existing door or window in the same opening - that typically falls under Permitted Development. But if you're making the opening larger or creating a new one in an external wall, you may need planning permission or Building Regulations approval. Conservation areas, listed buildings, and properties with an Article 4 Direction have tighter rules, so check before assuming. Any structural work to the opening, like fitting a new lintel, needs Building Regs sign-off regardless.
Does my extension need Building Regulations approval even without planning permission?

Almost always, yes. Planning permission and Building Regulations are two separate things. Extensions need to meet regulations covering structural integrity, fire safety, insulation, ventilation, and drainage - regardless of whether you needed planning approval. Your local authority's building control team can confirm exactly what's required. And don't skip it - missing Building Regs sign-off can cause real headaches when you come to sell.
How long does a typical home extension take?

A small single-storey extension usually takes eight to twelve weeks from groundworks to completion. Add several months if planning permission is needed before work can even begin. Bigger builds - two-storey additions or anything needing significant structural work - can take four to six months or more. Get a realistic timeline from your builder upfront, and factor in a buffer for the unexpected.
