How Roofs Work: From Shingles to Structure
A roof is a layered system that sheds water, controls air and heat, and transfers loads safely to structure. Cladding and underlayment manage runoff and UV; membranes provide primary water and air control on low-slope roofs. Insulation guarantees thermal continuity and limits condensation. Decking acts as a diaphragm; rafters or trusses resolve gravity, uplift, and […]
The Ultimate Guide to Understanding Your Roof
This guide explains roof types and selection by climate, pitch, and load paths. It compares materials—asphalt, metal, tile, slate—by lifespan, cost, and structural demands. It outlines components: framing, sheathing, underlayment, flashing, ventilation, and gutters. It flags early failure signs, including stains, granule loss, and attic condensation. It provides seasonal maintenance checklists and ventilation targets. It […]
