Finding a suitable tile or slate match
The council’s Whitkirk appraisal describes houses close to the pavement around the Selby Road and Colton Road junction, with more space in front of some properties farther along those roads. That difference matters when arranging access to the roof. Tell us whether scaffolding could stand within your frontage and whether there is a side passage; a street photograph can help explain a restricted approach.

Finding the cause
Ask whether the failed units are isolated and whether compatible replacements are available. Where earlier repairs have introduced a different covering, the roofer should explain how the junction works and whether correcting it is part of the proposed scope.
Planning your roofing work
Mention narrow entrances, side extensions and any roof over a bay or porch. These smaller structures can affect how the main roof is reached.
What belongs in your quote
A clear quote sets out the materials, access and waste removal, as well as the repair itself. It should also explain what happens if opening the roof reveals further damage, so you know how any extra work will be agreed.
Use the roofing quotation checklist or understand the main cost factors.
