Roofing & Roof Repairs in Bexley & Kent

Reliable Roofing Solutions Built to Protect Your Home

Your roof is one of the most important structural elements of your home. It protects everything beneath it — from the structure of the building to your belongings and everyday comfort. When roofing issues are ignored or poorly repaired, they can quickly lead to leaks, damp, heat loss, and costly structural damage.

At P J Dunbar Builders Ltd, we’ve been carrying out professional roofing and roof repair work across Bexley, Bexleyheath, Sidcup, Dartford, Eltham, Welling, Orpington, and the wider Kent area since 1994. As a long-established, family-run building company, we approach roofing work with the same care, planning, and attention to detail as any major structural project.

Whether you need a small roof repair, ongoing maintenance, or a complete roof replacement, our experienced team delivers safe, durable roofing solutions designed to last.

Our Roofing & Roof Repair Services

Every roof is different, depending on the age of the property, materials used, and exposure to the elements. We assess each roof carefully and recommend practical, long-term solutions rather than temporary fixes.

Roof Repairs & Leak Investigations

From slipped or broken tiles to damaged flashing and persistent leaks, we carry out thorough roof inspections to identify the true cause of the problem. Our repairs focus on resolving issues properly — preventing repeat damage and protecting your home long-term.

Pitched Roof Repairs & Renewals

Many homes across Bexley and Kent have traditional pitched roofs constructed with tiles or slates. We repair and replace roofing materials where required, ensuring correct fixing, weatherproofing, and ventilation throughout.

Flat Roof Repairs & Replacement

Flat roofs require specialist knowledge to ensure correct drainage and waterproofing. We carry out repairs and full replacements using durable, modern systems designed to withstand the elements and reduce future maintenance issues.

Ridge Tiles, Flashings & Roofline Details

Ridge tiles, lead flashings, valleys, and junctions are common points of failure on older roofs. We repair and replace these critical components to maintain weather resistance and structural integrity.

Chimney Repairs & Roof Penetrations

We carry out chimney repointing, flashing repairs, and structural maintenance to prevent water ingress and deterioration around roof penetrations.

Guttering, Fascias & Soffits

A roofing system is only as effective as its drainage. We repair and replace guttering, fascias, and soffits to ensure rainwater is safely directed away from the property and roof edges remain protected.

Benefits of Professional Roofing Work

Protect Your Home from Water Damage

Timely roofing repairs prevent leaks from developing into serious structural issues, damp problems, and interior damage.

Improve Energy Efficiency and Comfort

A well-maintained roof reduces heat loss and draughts, helping keep your home warmer and more energy efficient throughout the year.

Extend the Lifespan of Your Roof

Addressing small issues early can significantly extend the life of your roof, delaying the need for costly full replacements.

Maintain Property Value and Safety

A sound roof is essential for maintaining the value, safety, and insurability of your home — especially in older properties.

Got Concerns About Your Roof?

If you’ve noticed leaks, loose tiles, damp patches, or general wear and tear, it’s best to address the issue early.

Our process

Our Roofing & Repair Process

With over 30 years of experience, we follow a clear, reliable process for roofing and roof repairs. From initial inspection through to final completion, our approach focuses on safety, clear communication, and quality workmanship — ensuring your roof is repaired or replaced properly and built to last.

Initial Contact and Advice

We begin with a conversation about the issues you’ve noticed and any concerns you have. This helps us understand the urgency and nature of the problem.

Roof Inspection & Assessment

We carry out a thorough inspection to identify damage, wear, and potential weak points. This ensures repairs address the root cause — not just the symptoms.

Clear Recommendations & Quotation

Based on our findings, we explain the options available and provide a clear, itemised quotation outlining the recommended work.

Pre-Repair Planning & Safety Measures

Before work begins, we plan safe access, scaffolding if required, and materials to ensure the job is completed safely and efficiently.

Roof Repairs or Replacement Work

Our skilled, long-standing team carries out all repairs or replacement work with care, precision, and attention to detail — ensuring durability and weather resistance.

Final Checks & Ongoing Support

Once complete, we carry out final checks and remain available for future maintenance or follow-up advice.

Roofing & Roof Repair FAQs

How do I know if my roof needs repair or replacement?

Common signs include leaks, missing or broken tiles, sagging areas, damp patches, or excessive moss growth. We assess whether repairs are sufficient or if replacement is the better long-term option.

Do you offer emergency roof repairs?

Yes. Where urgent repairs are required to prevent further damage, we aim to respond as quickly as possible.

How long do roof repairs take?

Minor repairs may take a day, while more extensive work can take longer depending on access, weather, and the extent of damage.

Will roof repairs be disruptive?

We minimise disruption wherever possible and explain any access or scaffolding requirements in advance.
