How to Keep Seagulls Away From Your Roof and Chimney

Written and reviewed by Elaine Bliss, Technical Manager, PestFix

The most reliable way to keep seagulls away is to stop them landing on the places they use. On most homes that means stainless steel seagull spikes on ledges and parapets, triangular ridge spikes or post and wire along the roof ridge, a chimney spike on the pots, and netting over larger areas such as flat roofs and light wells. Scarers such as hawk kites and distress call units can help on open sites. Because all gulls are protected and they nest from spring, you should have the proofing in place well before the nesting season starts. Seagull spikes cost £3.36 per metre from EnviroGuard, including VAT, and you can request a free installation quote if you would rather not work at height yourself.

Which product for which surface

Gulls are bigger, heavier and longer legged than pigeons, so the products are sized for them. The right choice depends on where the gulls are landing, so start by working out which part of the building they are using.

Roof ridges

If gulls are standing on your roof ridge, triangular ridge spikes are one answer. They are made from 304 grade stainless steel with a triangular base that sits on the ridge tile, and they are fixed with silicone adhesive. The spikes are 140mm high, which protects against both pigeons and gulls, and they cost £12.00 per metre.

If you would prefer something less visible, post and wire runs a sprung wire above the ridge so gulls cannot settle on it. The seagull post and wire kit for triangular ridge tiles and the seagull post and wire kit for half round ridge tiles come in 15 and 30 metre lengths, and each kit contains the brackets, wire, springs, crimps, adhesive and a drill bit. See the full posts and wire range for other surfaces.

Chimneys

Chimney pots are a common roost on houses. The Chimney Bird Deterrent Spike is a stainless steel strap, 1096mm long, that wraps around round and square pots of any UK size, with 223mm pins designed to deter both pigeons and the larger gulls. It costs £29.75 and carries a 25 year no rust guarantee. For the gaps around the pots, the Scarborough chimney spike is a flat-packed set of 3mm stainless steel rods that you bend to shape and fix inside a pot, between rows of pots, or in the V where the stack meets the roof. It costs £32.40. You can find both in our chimney protection range, and if you are thinking about capping a chimney that is no longer used, our chimney cap cost guide covers the options.

Ledges, parapets, window sills and gutters

Stainless steel seagull spikes cover ledges between 185mm and 210mm wide and stand 165mm high. Gulls need that extra height, not just a wider spike. They are sold per metre at £3.36, have snap-off points so you can cut them to length by hand, and need one tube of adhesive for every 10 metres. For longer runs, the seagull spike and glue bundle includes 30 metres of spike and 3 tubes of adhesive for £118.26. On a half round or ogee gutter, the seagull spikes gutter kit holds 1 metre of spike on 6 gutter clips, from £8.32. Our seagull spikes buying guide explains what to look for in more detail.

Flat roofs and large roof areas

Where gulls are using a whole area rather than an edge, netting is the answer. Our 75mm seagull netting is knotted, UV stabilised polyethylene with a 75mm mesh, and when it is installed correctly it is the system that can be used with confidence where gull numbers are high and birds roost at night. Stock nets run from £9.50 for 5m x 5m to £152.14 for 20m x 20m, or you can have a net made cut to size at £0.46 per square metre plus a £15 cutting fee per order. On industrial and commercial flat roofs, non-piercing roof mounts weighted with paving slabs let you net the area without piercing the roof. See the seagull netting range for sizes and fixings.

On a large roof you may also use the Daddi Long Legs rotating bird spider. Its stainless steel wires rotate and bounce in the wind, and spacing several of them across the roof means gulls come into contact with them when they try to land. The 1.25m version costs £34.00 and the 1.8m version £41.95.

Gardens, bins and open sites

Gulls come back to places where they find food, so keeping bin lids closed and not feeding them takes away much of the reason to visit. On open ground, industrial roofs and landfill, a tethered hawk kite flies over the area and scares pest birds off. The kit with a 7 metre pole costs £37.68, and it should be brought down in strong winds. The BirdXPeller Pro plays the distress calls of gulls and other species and covers up to an acre of open ground at full volume. It costs £423.24 and, as its product page advises, it works better alongside visual scarers. Browse the full bird scarers range for other options.

Seagull deterrent prices

A worked example

Suppose gulls are standing on an 8 metre triangular ridge and on the two pots of a chimney. Eight metres of triangular ridge spikes at £12.00 is £96.00, and two Chimney Bird Deterrent Spikes at £29.75 each is £59.50. Your materials cost is £155.50, plus silicone adhesive for the ridge spikes. If you would rather have the work done, a fitted price depends mostly on access and height, whether a scaffold tower or cherry picker is needed, and how much cleaning is needed before fitting, so it is quoted after a survey.

Timing and the law

All wild birds, including every species of gull, are protected under the Wildlife and Countryside Act 1981. It is an offence to intentionally take, damage or destroy a nest that is in use or being built, or to take or destroy its eggs. Herring gulls and lesser black-backed gulls have been removed from the general licences because their conservation status has worsened, and the herring gull is red-listed. That means there is no general licence you can rely on to remove a gull nest that is in use, and that includes a nest on your own roof.

Stopping gulls from landing or nesting in the first place needs no licence, provided the method does not injure a bird or trap it. That is why spikes, post and wire, netting and scarers are the routine answer for gulls. Gulls nest from around April to August, with eggs from around May, so roof proofing should be finished well before spring. In practice, autumn and winter are the time to do it. If a nest is already active, the lawful option is usually to wait until the young have left and proof the area afterwards. Our guide to bird control and the law explains the rules in full, including the different arrangements in Scotland and Wales.

Common questions

How do I keep seagulls off my roof?

Protect the places they stand. Fit ridge spikes or post and wire along the ridge, a chimney spike on the pots, and seagull spikes on any ledges or parapets. On a flat roof, netting or rotating bird spiders stop gulls settling across the whole area.

What is the best seagull deterrent?

For a building, the most direct approach is physical proofing, because it stops gulls landing rather than trying to frighten them away. The right product depends on the surface: seagull spikes for ledges, ridge spikes or post and wire for ridges, chimney spikes for pots, and netting for larger areas.

Do seagull scarers work?

Scarers such as hawk kites and distress call units are designed to move birds on from open areas such as playing fields, industrial roofs and landfill. The BirdXPeller Pro product page advises using it alongside a visual scarer for better results. On a house roof, spikes, post and wire and netting stop gulls landing in the first place.

Can I remove a seagull nest from my roof?

Not while it is in use. Removing or damaging an active gull nest, or its eggs, is an offence, and there is no general licence that covers it. Wait until the nest is no longer in use, then proof the area before the next season.

When should I put up seagull deterrents?

Before the nesting season. Gulls nest from around April, so autumn and winter are the best time to fit proofing, while the roof is clear.
