The Anatomy of a Roof: Understanding Basic Terms

Why Knowing Roofing Terms Matters

You don’t need to be a builder to understand your roof. A basic knowledge of roofing terms helps you spot problems early, avoid miscommunication, and feel more confident when speaking with roofing contractors.

As an NVQ-qualified roofing company serving Norfolk and Suffolk, Advanced Roofing Specialists believes that every homeowner should be informed about their roof.

This guide covers the essential roof parts and what they do.

1. Roof Covering: Tiles, Slates and Flat Membranes

This is the outermost layer and the one we see first.

Tiled roofing is common across Norfolk and Suffolk. Clay or concrete tiles add charm and protect against harsh weather.

Slate roofing, often found on traditional homes, offers longevity and a classic appearance.

Flat roofs, usually on garages or extensions, use membranes such as felt, GRP, or EPDM. These materials are highly durable and require expert installation.

2. Roof Decking or Sheathing

Under the tiles or slates lies the decking — usually plywood or timber boards.

This layer supports the entire roof structure. If your tiles become damaged, the decking can suffer, leading to leaks or sagging.

Regular inspections by trusted roofers near me can help avoid long-term damage.

3. Underlay or Membrane

The underlay sits directly on the decking. It acts as a second barrier against moisture.

Modern underlays are breathable. They allow moisture to escape while preventing rain from getting in. If you're having your roof redone, ensure underlay is included.

4. Roof Structure: Rafters and Trusses

These internal supports are the framework of your roof.

Rafters run from the ridge to the eaves, while trusses are prefabricated units designed to hold the structure together.

Any weakness in these elements can affect the entire roof and should be handled by accredited roofing contractors UK.

5. Fascia, Soffits and Guttering

At the edge of the roof, you’ll find fascia boards. These hold the guttering and give a finished look.

The soffits are tucked under the eaves. They help ventilate your attic and prevent pests from entering.

Advanced Roofing Specialists offers both UPVC and traditional timber fascia and soffit installations.

6. Flashing and Lead Work

Roof joints are vulnerable areas where water can seep in.

Lead flashing is used to seal these junctions — especially around chimneys and skylights. It’s flexible, durable and recyclable.

We specialise in professional lead work that’s both secure and long-lasting.

7. Ridge, Hips, and Valleys

The ridge is the top of your roof where two slopes meet.

Hips are the outer corners, and valleys are internal angles that collect water.

All three need precise installation to prevent water ingress. NVQ qualified roofers will ensure these are watertight and durable.

8. Ventilation and Skylights

Proper airflow in your roof prevents condensation and mould.

Roof vents are key to this. Skylights and roof lights not only add natural brightness but also aid ventilation.

We supply and fit both pitched and flat skylights, tailored to your home’s needs.

9. Chimneys and Chimney Stacks

Older homes often feature chimneys. These require specialist maintenance, particularly around the base where the chimney meets the roof.

Look for signs of damaged flashing or cracks. Regular checks can save expensive repairs later.

10. Eaves and Overhangs

The eaves are the lower edges of your roof.

They protect your walls and foundation by directing water away from the house. Damaged eaves can lead to water seepage and even structural problems.

Our roofing company in Norfolk and Suffolk ensures your eaves are fully protected.
