Request a re-roof quotation0800 433 2215Think about the junctions as well as the main roof
Chimney flashings, valleys and the meeting point with a neighbouring roof can all influence a replacement. A roof survey needs to consider the source of problems, not just where a damp mark appears indoors. Tell us what you have noticed and whether the roof has been repaired previously.
Replacing a roof on a terraced or semi-detached property
Where the roof joins another home, the existing covering and levels affect the boundary detail. Access for the work and removal of materials also need planning. If there is a porch, bay or rear extension, let us know whether it is part of the proposed job so the quotation is clear.
Confidence comes from a clear agreement
Compare the proposed covering, underlay and battens, leadwork, waste arrangements and VAT as well as the final price. We normally use a 30% booking deposit and 70% final payment, with agreed stages on larger jobs. Roof replacements have a minimum 10-year guarantee, with the scope and terms in the documents.

Before you book your Seaforth roof replacement
Does a replacement roof come with a guarantee?
Yes. Our roof replacements come with a minimum 10-year guarantee. Your quotation and guarantee documents set out the scope and terms. The guarantee is provided by Roofing Ninjas. We are working towards certification for insurance-backed guarantees; these are not currently available.
Will my quotation include clear VAT and payment details?
Yes. We are VAT registered and show VAT and the total payable. We normally take a 30% booking deposit and 70% on completion. Larger projects can have agreed staged payments linked to completed work. We accept credit cards but do not offer finance ourselves.
Can I send photographs before arranging the next step?
Yes. Send your postcode, a short description and any existing photographs on WhatsApp. Photos help us understand your enquiry, though they cannot replace a full assessment of the roof.
A roof we can put our name to. Or we do not take the job.
It is understandable to worry about cowboys when so much of the work is out of sight. We would rather show you what doing it properly means: clear preparation, suitable materials and care with the details you may never see from the ground.
We will not agree to hide known defective work beneath new tiles or use a specification we cannot stand behind. If a job only works financially by cutting those corners, we would rather turn it down. Taking longer and earning less on a job is preferable to leaving work we are not proud of.
Most of our work comes through referrals and word of mouth. That reputation matters more to us than rushing onto the next booking.
See why the preparation matters
On one roof we corrected, older roofing had been left beneath the later work. We stripped it, renewed the felt and battens and carried out new leadwork. See the actual correction.
