Project Overview
The homeowner contacted us to resolve persistent moisture ingress and modernize the exterior weatherproofing of their semi-detached home. The property suffered from an aged, deteriorated flat roof extension prone to standing water, crumbling mortar along the gable end verges, and tired, high-maintenance roofline timbers.
We delivered a comprehensive exterior overhaul: stripping and installing a multi-layer torch-on mineral felt system, repointing and sealing the main roof verges, and fitting low-maintenance white uPVC fascias, tongue-and-groove soffits, and high-capacity black half-round gutters.
Challenges & Initial Condition
Failing Flat Roof Membrane: The existing extension roof had weathered, showing surface blistering, loose joints, and signs of ponding water.
Degraded Verge Mortar: The roofline along the brick gable suffered from weathered, cracked cement bedding, exposing the tiles to wind uplift and rain penetration.
Dated Roofline Trim: The original timber fascias and soffits were deteriorating, requiring regular painting and failing to channel rainwater efficiently away from the brickwork and window frames.
Our Solution & Execution
1. High-Performance Torch-On Felt System
- Stripped the extension roof down to sound structural decking.
- Prepared the deck and laid a heavy-duty, reinforced Danosa elastomeric underlay membrane with fully bonded laps.
- Applied a durable, mineral-surfaced cap sheet designed for maximum UV stability, impact resistance, and long-term waterproofing.
- Formed neat upstands against the adjacent tiled elevation and finished the perimeter with clean drip edges to guide rainwater run-off straight into the drainage system.
2. Gable End Verge Re-Bedding & Sealing
- Erected safe access scaffolding to service the steep gable roofline.
- Removed cracked, loose mortar from the tile edges along the verge.
- Mechanically bedded the edge tiles using a durable, weather-resistant sand-and-cement mortar mix, creating a flush, uniform, and water-tight edge against high winds.
3. Low-Maintenance uPVC Roofline Overhaul
- Fitted heavy-duty, clean white uPVC fascia boards and tongue-and-groove ventilated soffits around the perimeter.
- Installed sleek black half-round gutters with heavy-duty brackets to ensure optimum gradient fall for rapid rainwater discharge.
- Protected the window headers and exterior walls from back-splatter and moisture staining.
Results & Impact
- 100% Watertight Protection: The combination of a robust, multi-layer mineral felt roof and freshly sealed tile verges ensures full defense against harsh seasonal weather and wind-driven rain.
- Curb Appeal Modernization: The crisp white soffits, glossy fascias, and black guttering create a striking contrast against the red brickwork and clean up the entire roof perimeter.
- Zero Maintenance: Replaced decaying timber elements with UV-stable uPVC that will not rot, flake, or require repainting.
