Top Tips For Your Ridge And Hips

Heritage Styles Of Ridge

A lot of our customers want that old york stone look to their property. However the cost of real york stone isn’t viable for a new house build or main roof re-roof.

In this case a buff mark 2 ridge is a classic solution and look great with matching wall cappings also from tombola, or you can choose the recon concrete cappings as an alternative to give your property a new modern feel.the chiselled texture on the surface is formed by machine chiselling along a computer drawn template. The ridges are then scored with a diamond blade as the concrete sets in order to achieve an authentic hand hewn look.

The range represents the most popular profiles of ridge used in the conservation roofing sector.with our traditional range of stone-cut styles you can create the look of specific regions across england. Our conservation ridges allow you to achieve a ‘picket fenced’ cottage garden effect with old hundred year old rural and urban style backyards, retaining walls and hedged areas.we can safely assume that prior to the installation of artificial slate in the mid to late 1800’s, stone ridge tiles were all roof tops would have had.

This was a fairly primitive solution for a pitched roof as around a quarter was lost due to the pitch of the roof.stone ridges offer authentic hand carved textures teamed with the modern step free lipped edge design. Stone ridges are available in buff, grey and york stone colours. Traditional fillers, including oak end offs and dovetail joints are all included as standard.

Pitch Considerations

Pitch is the slope of a roof – 100% being a completely flat surface and zero being vertical. Once you’ve established a pitch, it’s essential to design the roof accordingly, otherwise it could become distorted or compromise the building’s structural integrity.

The rafters are sized to support one another in such way that they transfer loads from one to another and ultimately to the foundation. This also helps ensure that the ridge beam is properly supported which prevents sagging in between rafters.new builds will often have the smaller pitch (12.5) set for standard off-the-shelf components.

The common angle for these would be 12.5 allowing your windows and dormer to fall into a plane with the main roof section. The vertical pitch of most steeper pitched roofs is around 45 degrees, as this is the angle that lends itself to most guttering systems and best covers any lean-to extensions at a shallow slope from the main roof section.the pitch is the angle of the roof, and in that sense it is the steepness of a roof.

It is usually referred to as the rise over run, or r.r., as in 1:12 for instance, which would be a 1 inch rise for every 12 inches run. Before we talk about the different types of roofs and the pitch considerations associated with them, lets discuss what causes pitches to become steeper on some roofs rather than others.


The majority of right traditional finials are made from copper, this was due to the ease of shaping and the ability to coat with copper sulphate solution (cus04) quickly.

Finials were usually placed above each ridge tile of a roof covering the ends of the ridge timbers at the apex of a roof.

They acted as counter weights to prevent damage and/or toppling down through heavy snowfall.

Ridge And Hips Installation

Ridge and hips are the primary elements that make a roof waterproof and safe to walk on.

Gluing it in place is arguably more important than which brand or type of tile you use. It’s essential that tiles are fixed using a flexible, self-levelling and moisture-curing adhesive.installation of ridge and hip tiles is not too difficult as long as you take your time, lay out the tiles and mark out on a tarpaulin.

Then using the correct adhesive a layer of glass mat and then finally the ridge and hip tiles.installing ridge and hip tiles is more simple than you think.

The first step is to lay out your ridge tile so that you can cut it to size. For the best cut, use a hacksaw and cut along the highest point of the roof ridge.

Comparative Cost

There is a dry ridge and a flash-and-batt type. My builder used the flash-n-batt which is a combination membrane to protect against water penetration and then battens of wood called hips over it to hold the extra weight of the tiles in place.

This works out quite well as they are cheaper because you only need to buy them once. The second time can be saved for not using flash-and-batt, costing $200-250 per pitch versus $1000+.the main difference between a ridge roll and hips roll is that ridge rolls sit on the apex of a roof while hips rolls cover the hips or valley at the sides of a roof. Dry-ridge rolls come in polythene or epdm membranes.

Polythene dry-ridge rolls are available in three sizes: 3m x 15m, 3m x 20m and 3m x 25m.the most popular packs are the 10m roll-out membrane (8-10 rolls per membrane), and the 3m roll-out membrane (around 5 rolls per membrane). This means that a 10m pack of ridge and hips is less expensive than a 3m dry-ridge pack.a typical hip may cost up to $200 but a ridge could cost as much as $400. Also, the more membrane you purchase the bigger your discount will be and the less you will pay per roll-out.

Ridge Repairs

We had someone come to look at the tiles on our roof and the ridge beam. There is buckling in a corner of the ridge, it was worse this morning when the sun came up. The man uses a ladder to get to the top of the house.

He says it could be dangerous and said we should strip off the slate tiles and replace them. It is going to cost £5k but he says we can claim it back on insurance.”. Second on the list of required repairs would be ridge and hips.

If tiles are loose, or if the ridge has subsided substantially, they should both be replaced at the same time to avoid cracking the tiles with access to the lower section of roof is now easier from reaching it via the offending side of the roof!. Be careful with decorative strut tiles, they are not made to support the roof and can easily be damaged by tradies walking on them. In most cases loose ridge or hip tiles are a sign of roof movement and replacing these tiles is important and needs to be done carefully.check the ridge tiles up to 1m from the edge of the roof (near gutters) for a hollow sound when tapped. Also look for continuous cracking whether in vertical or horizontal lines.if you have loose ridge tiles the overall condition of your roof is likely to be compromised – find out now.
