RoofBLOCK Bat Box

The Eco-friendly RoofBLOCK Bat Box provides a better solution.

Despite the old saying "As blind as a bat", bats actually have fairly good eyesight and use a type of radar to locate objects. Bats are very special, they are the only mammals that can fly like a bird and we should all make an effort to accommodate them and a RoofBLOCK bat box makes ideal homes for this clean little creature. 

RoofBLOCK Ltd who make an innovative roof overhang in long-lasting masonry have adapted their concrete block to accommodate bats.  With a small slit in the base of a RoofBLOCK and one end sealed, the masonry bat box is designed to be built-in with another sealed end RoofBLOCK on the opposite side but without a slit to form a maintenance-free alternative to wooden or plastic fascias and soffits around the roof of a building. 

Bats don’t like draughts and need to be safe and hidden - RoofBLOCK makes an ideal roost for bats as they are contained within the hollow part of the block on the exterior of the building and cannot enter your home

RoofBLOCK bat boxes can also be linked with extra blocks to form a larger roost where they are located on a warm aspect of a building. Once occupied, it is an offence to intentionally or recklessly damage, destroy or obstruct access to any structure or place that a bat uses for shelter or protection.

Siting RoofBLOCK bat boxes

This advice is in respect of siting a RoofBLOCK bat box to provide a potential new roost for bats and is not to be used as advice where mitigation or compensation is required for an existing bat roost.

Aspect

It is helpful to install the RoofBLOCK bat boxes in more than one aspect of the building to allow a choice of roosting conditions. Bat boxes located on a shady side will remain cooler and will be more suitable for use during the hibernation period (winter) or by male bats all year round. Those located where they will receive heat from the sun are more likely to attract females to use as a maternity roost during the summer.

Other considerations

To make the bat box a potential roost for a wider range of bat species, it is helpful to consider whether there is nearby linear vegetation features such as hedges.  This is because some bat species use these features for navigation between their roosting site and feeding ground and to avoid flying in open and exposed areas. Do ensure that no artificial lighting will fall on the bat box or its immediate surrounds, as this will prevent bats from using it.

Wherever possible, and particularly on the warmer aspects of the building, it would be valuable to locate RoofBLOCK bat boxes adjacent to one another so that the internal void is continual for a greater length, thereby giving more room for use by female bats gathering to have their pup.

-----------------------------------------------

Bats are tiny little creatures, very shy and totally harmless. On summer evenings, at twilight they emerge from their roosts and flit across the sky, darting with impressive speed and agility in pursuit of insects.  They catch and eat around 3,000 insects an night!  This huge appetite is necessary to sustain the bat, who, measuring a mere 4cm (1½ inches) for the Common Pipistrelle with a wingspan of 20cm (8 inches) burns up a lot of energy in flight.

There are 17 species of bat in the UK, all are protected by law because their numbers have decreased so dramatically.  Roosting in concealed crevices, only the horseshoe bats sleep hanging free by their feet.  

During spring, bats return from migration or awaken from hibernation and the females begin having baby bats called "pups". Bat mothers only have one pup at a time and not always every year. 

Mothers congregate in summer months for several weeks to give birth to their young, which like all mammals are born alive and suckle on milk.  When the babies can feed themselves and fly the bats move on.  In winter the bat will seek out a cool safe roost to hibernate in.  

Incidentally, by Halloween our local bat population is tucked up in their roosts and not out looking for blood.  Of over 1,100 bat species worldwide only three feed on blood and they reside in Central and South America.
