Roof Upgrades with RENOTEC® Roof Coating in Dorset & Hampshire - A Smarter Alternative to Roof Replacement
At Proofterior, we help homeowners across Dorset, Hampshire, and the South of England protect and extend the life of their roofs using the RENOTEC® Roof Coating System, a premium, long-lasting alternative to full roof replacement. Designed for ageing but structurally sound roofs, this advanced roof coating restores tile appearance, seals out moisture, and defends against moss, algae, and weather damage, delivering a cleaner, brighter roof for up to 10 years.
Engineered with advanced hydrophobic technology, RENOTEC® creates a water-repellent, self-cleaning surface that prevents water absorption and reduces biological growth. Rainwater runs freely off the tiles, helping the roof stay cleaner for longer, maintain colour vibrancy, and gain extended protection against environmental wear, UV exposure, and ongoing moisture damage.
RENOTEC® Roof Coating System
When a roof is structurally sound but showing signs of ageing, surface wear, or moisture exposure, full replacement is not always necessary. The RENOTEC® Roof Coating System is a premium, long-lasting upgrade that protects, refreshes, and extends the life of existing roof tiles without the cost or disruption of re-roofing.
RENOTEC® roof coating can:
Delay the need for re-roofing
Improve roof performance and appearance
Reduce ongoing maintenance
Enhance weather resistance without major structural work
When correctly specified and applied following professional assessment, RENOTEC® seals out moisture and protects against moss, algae, and weather damage, delivering a cleaner, brighter roof with long-term protection of up to 10 years.

How RENOTEC® Works
RENOTEC® is engineered with advanced hydrophobic technology that creates a water-repellent, self-cleaning surface. Rainwater beads and runs off the tiles, carrying dirt and contaminants away rather than allowing them to settle.
This hydrophobic layer:
Reduces moisture absorption into roof tiles
Resists moss and algae regrowth
Protects against environmental wear and UV exposure
Helps maintain colour vibrancy and surface integrity
Extends the service life of the roof covering
Unlike cosmetic coatings, RENOTEC® is designed for performance as well as appearance.

The Problems RENOTEC® Solves
Over time, roof tiles can become porous and absorb water, making them vulnerable to moss growth, surface breakdown, and recurring leaks. These issues are especially common in exposed or shaded areas where moisture lingers.
RENOTEC® addresses common roof problems such as:
Water absorption through ageing or porous tiles
Moss and algae growth holding moisture on roof surfaces
Surface degradation caused by UV exposure and weathering
Fading, discolouration, or uneven roof appearance
Early signs of tile deterioration where replacement is not yet required
By sealing the surface and improving water resistance, RENOTEC® helps prevent these issues from worsening.

How Proofterior Delivers RENOTEC® Roof Coating
Proofterior provides RENOTEC® roof coating as part of a survey-led roofing upgrade, ensuring the system is applied only where appropriate.
Assessment
We inspect roof condition, tile integrity, moisture behaviour, and exposure to confirm suitability for RENOTEC® coating.
Preparation
Roof surfaces are thoroughly cleaned and prepared to remove moss, algae, and contaminants, ensuring proper adhesion and performance.
Application
The RENOTEC® coating system is applied by our in-house team using approved methods to achieve consistent coverage and protection.
Protection
Once applied, the roof gains enhanced resistance to moisture, biological growth, and weathering, supported by clear reporting and aftercare guidance.
Areas We Cover
Proofterior provides independent damp surveys and specialist damp proofing services across Dorset, Hampshire, and surrounding areas. We work with homeowners, landlords, property managers, and buyers who need clear answers, accurate diagnosis, and long-term solutions, not guesswork or sales-driven recommendations.
Frequently Asked Questions
How long does RENOTEC® Roof Coating last?
RENOTEC® Roof Coating offers up to 10 years of proven protection, maintaining colour vibrancy and resisting moss, algae, and weather damage.
Is roof coating better than roof replacement?
For structurally sound roofs, coating is more cost-effective than replacement, improving appearance and extending tile life without the disruption of a re-roof.
Will roof coating change the colour of my tiles?
Yes — RENOTEC® offers a range of premium, UV-stable colours to refresh and enhance your roof’s kerb appeal.
Does roof coating stop moss and algae growth?
RENOTEC® uses hydrophobic, self-cleaning technology that helps prevent moss, algae, and dirt build-up, keeping your roof cleaner for longer.
How long does the application process take?
Most roof coating projects in Dorset and Hampshire are completed within 2–3 days, depending on roof size and weather conditions.
Can roof coating improve my home’s energy efficiency?
By reducing water absorption and protecting tiles, roof coating helps maintain the roof’s insulation performance, which can contribute to better energy efficiency.
