Don't start your slanted shed roof upgrade before reading our top tips on how to and what roofing style to choose below...

Sheds are the perfect accompaniment to any garden whether you use them solely for storage, to hide those bulky (unwanted, really!) household items, bikes or tools, or for something a little more fun like a home cinema or even a micropub! Maybe your shed has become your new relaxation room, home office or hobby den. Whatever you use your garden shed for, you’ll want to make sure your shed roof stands the test of time so those bits and pieces, equipment or maybe even works of art don’t get ruined in the unpredictable UK weather!

But where to start? Our step by step guide will help you to build or upgrade your shed roof...let’s start.

Choose your shed roof style!

By choosing Onduline roofing, we have a wide range of shed roofing available, we even have clear ranges suitable for greenhouses, and whether you purchase via us or another shed roofing company, the style you choose may have an impact on the installation.

CLASSIC shed roofing

Corrugated sheets

For a classic design, corrugated shed roofing is likely to be the best choice and our (surprise, surprise) ONDULINE CLASSIC sheets are the original bitumen corrugated roofing sheet but, unlike some others, ours are made from 50 - 60% recycled materials offering your style and substance.

How do you install corrugated roofing?

We can’t necessarily speak for other providers but our corrugated roofing is super easy to install, - you can even install it over the top of existing felt! - just follow these steps…

  1. Lay the sheets over the gutter line with an overhang and lay them in the opposite direction to the wind
  2. Lay your second row so the first sheet is parallel to the corrugations but not in line with the first
  3. Fix the sheets at the eaves, overlaps and ridges with the correct fixings
  4. Fix a verge to the edge for ultimate aesthetic, waterproofing and wind resistance. Fix to the sidewall first and then the roofing sheets with an overlap

And you’re done! You can find out more by reading our full ONDULINE CLASSIC installation guide which also tells you about the batten rules, if you’re not fixing your new roof to a roof deck, and how to calculate the pitch of your roof. We also have a handy ’How to’ video.

CLASSIC Inspiration

We love seeing your installations and these are just two of our favourite CLASSIC looks.

Pastel pink shed with ONDULINE CLASSIC roofing sheets

Pretty in pink - Grey CLASSIC roofing

This style of shed is sure to stand out in any garden. We love how Gemma, of the Instagram account Caffeine & Cacti, has complimented her grey decking with a matching grey shed roof using our CLASSIC sheets. Any other colour and we think the overall look wouldn't have been so stylish. Would grey roofing suit your shed’s design?

Shed with green Onduline roofing sheets

Switch it up - Green CLASSIC roofing

If you’d prefer to make a statement with your roofing rather than the colour of your shed walls, then this design from Ella, of the Instagram account The Russells Home, is definitely up your street! We love how the green CLASSIC sheets add a touch of colour without being too overbearing. And how gorgeous does it look with the evening’s mood lighting?

Tiled roofing

Green ONDUVILLA roofing sheets on lean to shed

The continental look

Traditional tiled roofing can be difficult to install and costly too! It may not even be suitable for your shed roof. So, how do you achieve a quirky tile look without the risk? Our ONDUVILLA roofing tiles, of course. Again these are corrugated roofing tiles but they are made to replicate the clay tile look without the hassle.

How do you install tiled roofing?

  1. Apply the ONDUVILLA foam fillers at the eave of your shed roof
  2. Lay the sheets in the opposite direction to the wind, starting at the eave with a small overhang and fix the corrugations as you go!
  3. Lay your second row with a stagger so it is again parallel to the corrugations but not in line with the first row - correct overlapping ensures proper waterproofing!
  4. As with the corrugated sheets, fix a verge to the eave edge starting at the sidewall and then on top of the corrugation
  5. Apply the ONDUVILLA foam fillers on either side of the ridge line and cover the ridge with the slim cap - fix on each side
  6. Finish the ridge with the closure cap and you’re all done!

You can find out more by reading our full ONDUVILLA installation guide which also tells you what to do if the opposite end of your roof doesn’t finish with a corrugation, and how to calculate the pitch of your roof.. We also have a handy ’How to’ video.

Tile Look Inspiration

Here are a few of our favourite tile look installations…

Traditional summerhouse shed with ONDUVILLA roofing sheets

Summerhouse fun - ONDUVILLA shaded brown roofing

What a wonderfully traditional summerhouse, we can imagine ourselves enjoying the sunnier UK weather with the doors and windows wide open, or cosied up under a blanket with them shut tight in winter, a book in one hand and a drink in the other.

Roof Shingles

Grey BARDOLINE roof shingles on grey shed in garden

Flat rather than corrugated

Similar looking to felt in their flatter design (compared with corrugated sheets), roof shingles for sheds are typically better than felt because they are made from more robust materials and our BARDOLINE CLASSIC roof shingles are no different. Made from specially formulated bitumen and reinforced with glass fibres, they’re also AA Fire rated.

How do you install roof shingles?

Unlike some other shed roofing - like our CLASSIC and ONDUVILLA ranges - roofing shingles must be installed onto wooden decking, just like felt.

  1. Before you can install your shingles, you’ll need to install a watertight and bitumen underlay like our ONDUTISS membrane
  2. Prepare your first strip by cutting the headlap of the singles, apply some adhesive near the eave of your roof and place this strip on top, securing it with the correct fixings
  3. Then place your next strip of shingles by creating an overlap, securing with the correct fixings again
  4. Repeat this step staggering the shingles by shortening the strip until the roof is covered
  5. Cut some spare shingles to make a ridge - or use a BARDOLINE detail strip - and attach this to your roof using the correct fixings and adhesive, in the opposite direction to the wind

And you’re all done! Find out more by reading our full BARDOLINE roof shingles installation guide which also tells you in more detail how to create your roof’s ridge from your spare shingle and what tools you’ll need. We also have a handy ’How to’ video.
