Overview

Choosing the right gutter system for your UK home is crucial for effective rainwater management and protecting your property from water damage. This guide explores two popular materials—PVC and steel—and two common profiles—half-round and square—for residential buildings, helping you make an informed decision.

PVC Guttering

PVC (uPVC) guttering is a cost-effective, lightweight, and low-maintenance option, widely used in UK homes since the 1960s. It’s easy to install, making it ideal for DIY projects, and comes with a standard 10-year guarantee. Available in colors like black, white, brown, and grey, PVC suits various aesthetics. However, it has a higher thermal expansion rate, requiring space for movement (e.g., 7.2mm for a 4m length in a 30°C temperature range). PVC is best for smaller residential properties like lean-tos or sheds but may not withstand extreme weather as well as metal alternatives.

Steel Guttering

Steel guttering, such as SAXON STEEL’s Stal system, offers superior durability and a premium look, with a life expectancy of over 50 years. Coated with magnesium zinc alloy, it resists corrosion and requires minimal maintenance. Steel is slightly heavier than PVC but easier to handle than cast iron, with a 15-year warranty on coated products. It’s ideal for homes in coastal or high-rainfall areas and suits both modern and traditional designs. However, steel is pricier, costing 20-30% more for a 3-bedroom semi-detached home compared to PVC.

Half-Round Guttering

Half-round gutters, typically 112mm in diameter, are a classic choice for UK homes. Their curved, semi-circle design ensures smooth water flow and reduces debris buildup, making maintenance straightforward. They suit traditional properties or cottages and are available in both PVC and steel, offering a balance of style and functionality for areas with moderate rainfall.

Square Guttering

Square gutters, usually 114mm wide, provide a modern, angular look and higher water capacity, making them suitable for homes in wetter climates or with larger roofs. Available in PVC and steel, they fit neatly against flat walls but may require more frequent cleaning due to debris trapping in corners.

Choosing the Right System

Consider your home’s architectural style, local rainfall, and budget. Half-round gutters suit traditional homes, while square profiles complement modern designs. PVC is budget-friendly and easy to install, while steel offers longevity and resilience.
