Stone and earth absorb and release moisture; lime plasters and paints allow this cycle, preventing buildup that breeds decay. A raised foundation lifts walls above splash zone, while capillary breaks block suction from saturated ground. Interior finishes remain vapor-open, balancing indoor humidity. Together, these choices create steady, forgiving environments where materials dry after storms, salts migrate outward, and structural cores remain protected without relying on sealed, brittle barriers that eventually fail.
Pitch, overlap, and texture matter more than material alone. Thatch, laid thick and combed, throws rain quickly, while wood shingles and clay tiles rely on courses, laps, and secure fixings. Ventilation beneath discourages condensation, and generous eaves protect walls. Valleys, ridges, and penetrations receive extra care to guide water harmlessly away. When maintained, such roofs become reliable guardians, exchanging occasional, predictable attention for decades of calm, dry rooms below.
Exterior coats must repel driving rain yet permit drying afterward. Limewash carbonates into a sacrificial layer, refreshed with a brush and a bucket as seasons demand. Clay plasters inside regulate humidity, easing respiratory comfort and protecting timber. Avoid hard, impermeable membranes that trap moisture where decay thrives. Think of finishes as coats you can mend, not armor you cannot remove, keeping walls honest, breathable, and easily cared for by future hands.
