Yes, Easy Slate and Plain Easy along with the Easy Roof System as a whole can be used alongside reclaimed products. Many renovation projects rely on the Easy Roof System to weatherproof historical roofs while using as much of the original materials is preserved as possible. Have a look at some of our Case Studies by clicking here to learn more.
Providing the integrity of the slate or plain tile meets the criteria set out in BS5534 and is fit for purpose, East Slate and Plain Easy are ideal for ensuring a weatherproof roof with reclaimed products.
Permavent can offer off-the-shelf and bespoke solutions for this application. If you would like to discuss your requirements you can follow this link to speak to your local Permavent representative: Contact Your Area Sales Manager.
When installing onto traditional sarking boards with no additional slating battens, we advise that you use Easy Verge Trim.
Yes, Easy Soaker provides a replacement for traditional lead flashing and because it is made with high quality plastic instead of lead it is cheaper to produce and thus cheaper to purchase. It also offers time and labour savings that are significant, being easy and intuitive to install. We estimate that savings of up to 80% are achievable using Easy Soaker instead of lead.
The Plain Easy system is designed to weatherproof a plain tile roof at a low pitch. Since valley and hip tiles are manufactured to be used at standard pitches rather than low pitch the Plain Easy system would not be required. As such, alternative detailing is recommended, please speak to one of the technical team for further information. You can find contact details by clicking here.
Plain Easy separates the tiles from one another and presents a small gap which stops the capillary action that would cause water to be drawn under and around the tiles, significantly reducing the occurrence of freeze-thaw related cracking caused by this kind of water ingress.
Yes, in accordance with guidance provided by BS5250 and fibre-cement slate manufacturers.
Permavent roofing underlays should be affixed using clout nails. It’s important that the nails are located beneath laps, to ensure that the underlay prevents water penetration.
Different membranes have differing requirements when it comes to ventilation and that requirement can rely on a variety of factors. Please speak with a member of the technical team, who will provide the correct information to find the right product for your design. Click here to find contact details.
In accordance with BS5534 the laps of a roofing underlay can be restrained in 3 ways:
1. Restrained with an integrated or external tape.
2. Restrained with a ‘fly’ batten.
3. Restrained using the existing tile/slate batten line. The most cost-effective and quality-assured way of achieving this is by installing a roofing underlay with a double integrated tape system.
Please install Easy Valley with the fixing that holds the cap in place at the higher end of the strip. This better helps to prevent water ingress.
No. The Easy Slate System ensures that water cannot penetrate into the roof system, even via wind-driven rain. The unique design stops water ingress and channels water off the roof.
When pitched at 12 degrees, Easy Slate is approved for use with a maximum rafter length of 8 metres.

A site visit is not a requirement for the guarantee, but images of the project before, during and after completion are necessary alongside the guarantee application. Read more about the Easy Roof System and Diamond GRP guarantees by clicking here.
Yes, the Easy Roof System can be installed unaffected by the addition of rooflights. The Easy Roof System is installed beneath the tiles or slates and also includes components for use at abutments, so including a rooflight or multiple rooflights will not disrupt the installation.
To ensure the integrity of the roof please seek guidance from the rooflight manufacturer as to the minimum pitch when using their products.
Yes – please see image of copper disc rivet application with Easy Slate.
Yes, Easy Slate can be installed using traditional hook-fixing methods.
No, since Easy Slate is installed beneath the edges of the slates it can be installed using traditional slate headlaps, there’s no need to increase the headlap. Please see our fitting instructions for more information: Click here to open/download.
As referenced in the Permavent BRE wind driven rain test report 273-259, Easy Slate is tested and approved as low as 12 degrees within areas of severe exposure.
No, in order to qualify for the 40 year guarantee the following criteria must be met:
The installation must be installed as per the manufacturer’s instructions and in accordance with BS5534:2014 + A2:2018.
The specified membrane must be PERMAVENT DRY+.
The specified tape must be PERMAVENT BUTYL TAPE.
The contractor must record both in-progress and completed project images to be supplied alongside invoices at the tie of guarantee application,
Guarantee applications must be submitted no later than 1 month after project completion.
Please note each Easy Roof installation requires its own submission.

Yes, as man-made or fibre cement slates have uniform properties they work extremely well when installed with Easy Slate.
The minimum pitch for plain tiles is recommended in BS 5534 as 35°.
By using the Plain Easy System it will allow you to install plain tiles as low as 17.5° and still be weatherproof.
The Easy Slate System will allow the installation of both natural and man-made slates at a pitch as low as 12°. The Easy Slate system will allow for the use of most kinds of slate, woch makes it ideal for heritage and listed refurbishment projects.
When installed in accordance with BS5534 the following Permavent construction membranes are suitable for all UK wind zones:
Permavent construction membranes are tested and verified UV stable for up to 3 months, so they’re fine to be left exposed. Almost all of them also boast an impressive W1 head of water resistance which makes them able to form part of a weatherproofing solution during construction.
Permavent APEX is the most cost effective Air-Open membrane on the market. The reduced lap (100mm) will decrease the membrane usage. The unique integrated double tape system will save time and labour, as well as eliminating the need for restraining battens or additional ‘fly’-battens.
The drying out period is the period over which the building dries. The building will have collected moisture during construction, especially if there has been inclement weather, as well as the materials themselves retaining some moisture. Once the membrane and roof is installed the internal area will begin to dry.
This period can very in duration for a number of reasons from the size and layout of the internal structure and perhaps most importantly the time of year. A building constructed in summer will dry out much faster than one built in the winter.
This drying out period can lead to condensation forming, which must be carefully managed via proper ventilation.
Permavent APEX is an air and vapour permeable roofing membrane that allows for condensation control in the roof without the need for additional ventilation. Read more about Permavent APEX by clicking the link here: Permavent APEX
The majority of breather membrane manufacturers recommend installing their membranes with a 150mm lap (225mm for lower pitches). Permavent APEX Taped with double-integrated tape, has been tested and approved for installation with a 100mm membrane lap.
A VCL is not required for non-ventilated cold roof installation. For further design support please contact a member of the team.
Yes, it can. Permavent APEX is UV stable for up to 3 months.
