The Self Build Self Help Site roof design

Ridge tiles - continued

If you are to have overlapping ridge tiles, and want to be finicky (we do) then ask your roofer to get the ridge tiles symmetrical. Many roofers just start at one end with a whole tile, and then cut the last one at the other end to the right length - see pics below. To get them symmetrical all it needs is some prior planning and to cut two ridge tiles - easy enough to just get that bit of detail right.

If you want to push the boat out a bit, then you could consider decorative ridge tiles and finials - see the pages from the companies advertised in the Product Finder - Roofing page.

Roof membrane

It is a good idea to use a vapour permeable (breathable) membrane, even if you are using over fascia or soffit vents. Its just belt and braces - the last thing you want is the roof timbers getting damp. You also won't have to worry whether the over fascia vents or soffit vents will get blocked over time.

Soffits, fascia and barge boards

The first consideration for these is often whether to have uPVC or wood. uPVC is low maintenance and only slightly more troublesome to put in. Other factors are the depth of the fascia and width of the soffit, and these are often dictated by the pitch of the roof - in that the soffit must not encroach below the top of the window - see diagram where the lintels are shown.
