What Roof Coating & Restoration Involves
Roof coating and restoration is worth understanding before you buy it, because it suits some roofs and is a waste of money on others. Where the covering is structurally sound but porous and weathered, cleaning and sealing can shed water better and tidy the appearance. Where slates are slipping, the felt has perished or the battens are going, a coating covers the symptoms and leaves the actual problem underneath. A contractor worth hiring will tell you which of the two you have.

Roof Coating & Restoration: Common Questions
Is roof coating a substitute for a new roof?
No. Coating treats the surface of a covering that is still sound. If slates are slipping across the slope, the membrane underneath has perished or the battens are soft, a coating hides that rather than fixing it. Any contractor who offers coating as an alternative to a needed re-roof is worth walking away from.
Which roofs are suitable for coating?
It suits concrete and clay tile that has gone porous but is not moving, and it is generally not recommended on natural slate, which does not need sealing and can be harmed by trapping moisture. The honest answer depends on an inspection, so ask what the roofer found rather than what the product claims.
How much does roof coating cost?
It is quoted on inspection, because the price turns on the area, the pitch, the access, the condition of the covering and how much cleaning and unit replacement is needed first. Ask for the preparation work and the coating itemised separately so you can see what you are paying for.
