First things first, swap out old, rotten timber battens should you need to. Once this is done, regardless of replacing battens, install a waterproof membrane under the battens. Step one: Start off with a double eaves course of shingles, leaving a minimum overhang of 38mm.
Maintain a broken bond pattern whilst nailing or stapling each shingle twice. Step two: When shingles are laid mark the position of the batten underneath, so you can achieve the most accurate fixing location when nailing and stapling. This will also aid in a straight line of fixings to improve the final look. Step three: Lay courses of shingles up the roof gradually until you get to the ridge. Step four: At the ridge, trim each shingle to create a shortened ridge course and then fix each shingle along the ridge twice.
Step five: Use pre-formed shingle ridge tiles and, nailing twice, fix these into place with a minimum overlap that is the same as the shingle gauge on the roof covering. When installing ridge and hip shingles, work inwards from the edges.
Top-tip: Use a waterproof membrane under the batten and counter batten to make sure the roof doesnt leak. For advice on products, installation and fixing, contact our customer service team on The better the quality of the materials, the more life youll get out of your roof.
Common grade is the cheapest and most inferior of the 3 types. Theyre randomly cut and made out of any part of the tree. These cedar shake shingles will be the first ones to split and warp.

Each one of these is hand-selected and straight grained. When the grain is straight, the shingles lay flat and you dont have to worry about them curling up. Your homes roof pitch is the angle, slope or slant of your roof.
The roofs pitch helps professionals estimate the number of materials needed to complete the roofing and decide on the best roofing materials. When it comes to slope for cedar roofs, pitch is determined by how many inches the slope rises every 12 horizontal inches.
For example, if the roof increases in height 4 inches over a span of 1 horizontal foot, then you have a four-in pitch or just a four-pitch. There are two main types of roofing slopes: a steep slope and a low slope.
Most homes are considered steep pitch, ranging from four-pitch to nine-pitch, but more dramatic rooflines may haves roof slopes of pitch to pitch. Low slopes are more typically used in commercial properties, but in the s, it was trendy to build homes with a low-pitch roof with just a bit of slope to allow for drainage. For determining how much material your roof will require, typically for steep slopes, the cedar shingles will have greater exposure to weather and the roofer will want to purchase more materials so each shingle has lessened exposure.
It is an option that is highly durable. It contains no organic material, so it does not break down very quickly. In addition, it requires much less maintenance than real cedar shakes. The roofing material is also much lighter than real wood shakes or cedar shakes. Unlike real cedar shakes, synthetic cedar shake roofing usually only lasts around 30 years.
The material can also start to fade over time. Another common mistake people make when choosing to install a cedar shake roof themselves is not aligning the shingles properly. Like with anything in construction, if you do not take the time to align the shingles, it can lead to countless problems.
If they are too close together, they can overlap too much, which can change their shape and damage them more easily. On the other hand, if they are too far apart, it can create space for precipitation to seep through and cause water damage. Many people opt to have a new chimney installed when they have a new roof placed on their home if their old chimney is leaning, cracking, or failing.

A roofer will measure the roof to calculate the square footage. These should be fixed with a 45mm x 2. Use the same gauge as the shingles at the ridge to give a more uniform appearance. This means ridges should be cut when they meet the central point. To speed up installation, use pre-formed hips and ridges.

The wood might expand or contract depending on temperature and moisture levels. Place the shakes or shingles under cover and off the ground outdoors.
The amount of acclimation time will depend on the wood you choose and your region. Use stainless steel, galvanized, or aluminum two-inch nails when working with cedar. If you use stainless steel, choose your alloy based on your distance from the ocean. Use a alloy if you live less than 15 miles from saltwater; otherwise, use a alloy. Using a nail with ring shanks prevents the nail from popping out as your cedar roofing expands naturally. Nail guns tend to fire the nail too far into the shingle, causing it to crack and eventually fall off.
Also, firing the nails quickly can cause you to miss the skip sheathing beneath the shingle. Any missed nails will be more likely to cause shingles to crack and curl. To avoid this, hand-nail two nails into each shingle. Place the nails four inches from the top and one inch from each side.
Starting at the bottom row, overlap each shingle at least an inch and a half over the edge of the roof, with the thick end at the top for the bottom row only. Then, add shingles above that with the thick part at the bottom. Leave about a quarter-inch space between each shingle so they can expand naturally. To achieve proper ventilation, you can use a cold roof system to ventilate your roof and keep it temperature balanced.
The three essential parts of a cold roof system are eave venting, ridge venting , and skip sheathing. Now that you know what to watch for, your roofing installation should go according to plan. Whether you hire a professional contractor or not, just make sure to do your research and equip yourself with the proper knowledge before you get started.
