Clearing Gutter Channels
Flat roofs collect debris. Autumn brings wet leaves from suburban lime trees right into box gutters, leading to hidden ponding above master bedrooms. Check the lead flashings around cheek walls every winter. Without seasonal clearance, stagnant rainwater creeps upward under cedar shingles or felt seams, dripping onto new bedroom ceilings.
Checking Window Trim Seals
Dormer windows face fierce wind. Driving rain batters vertical timber cladding, silicone perimeter beads, trickle vents and UPVC frames directly facing prevailing westerly winds. Timber fascias twist when unpainted. We remind homeowners that maintaining a Dormer loft conversion in Hounslow involves stepping outside with binoculars twice annually to spot cracked mastic before internal wallpaper bubbles.
Vapour Barrier Health Checks
Condensation damages hidden rafters quietly. Warm air from unvented en-suite showers rises through downlight holes into cold roof voids when extractor fans get switched off prematurely. Inspect loft access hatches. Damp insulation rolls lose thermal efficiency rapidly, leaving cold patches across dormer ceilings where mould spots start breeding behind bedroom wardrobes.
