Finding roofing contractors.
Make sure that you obtain several quotations for any work that you are planning, for comparison and ask about the tradesman about membership of
professional bodies such as the National Federation of Roofing Contractors. The NFRC is the UK?s largest roofing trade association representing
over 60% of the roofing industry by value.
Some tradesmen are regulated by the Trustmark scheme, check this for further peace of mind.
Roofing problems.
Cracking
Tile and slate can both crack, due to severe weather
as well as natural deterioration.
Cracking around the nail or peg holes also occurs. A
natural weakness, the expansion of rusting iron nails
or even swelling wooden pegs can exacerbate any
imperfection, such as ragged holes. (Continued below.)

De-lamination of the underside of the covering is characteristic of slate that has deteriorated through water ingress.
Clay tile is also affected by a similarly destructive process, but because it is man-made and not natural, it crumbles rather than delaminates.
Capillary action also occurs along the joints of tiles and slates and is then drawn to the under side of the covering and into the fabric.
Nail sickness
This is the term applied to nails that are so severely rusted that they can no longer perform their task properly. Years of condensation or rainwater ingress affect the integrity of the iron nails, which can finally fail.
Lack of maintenance can also be a problem, particularly on flat lead valleys, where a build up of detritus can occur. This can lead to the subsequent build up of rainwater and the eventual overspill of water into the roof void.
