Roof composition

Roof composition is defined by the visible covering and structure at the top of a building: tiles, slates, metal sheets, shingles, membranes, or planted systems, depending on the roof type. It usually reads as a durable outer layer over insulation, waterproofing, and framing, with details such as ridges, gutters, eaves, and flashing shaping the final look. The composition is chosen to balance weather protection, weight, drainage, and the architectural profile of the house.

Frequently asked questions

Which roof material is best for my house type?

It depends on the structure, slope, climate, and local rules. Steeper roofs often suit tiles, slate, or shingles, while low-slope roofs usually need membranes or metal systems.

Can a roof composition be changed without rebuilding the whole house?

Sometimes, yes. A re-covering or replacement may be possible if the framing, insulation, and waterproofing layers are in good condition, but damaged structure usually requires deeper work.

Will the roof color affect the look of the facade?

Yes. Roof color strongly affects the building’s overall tone, especially when the roof is large or highly visible. Dark roofs feel heavier and more graphic, while lighter or earthy roofs read softer and more traditional.
