Ridge Beam vs Ridge Board: A ridge board is a non-structural 1x member that aligns opposing rafters and carries no roof load, so it only works when ceiling joists or rafter ties tie the walls together. A ridge beam is an engineered structural member that carries roughly half the roof load down through posts to…
Standing Seam vs Corrugated Metal Roof: Standing seam hides its fasteners under raised interlocking seams and runs about $10 to $16 per square foot installed, lasting 40 to 70 years. Corrugated metal screws through the panel face, costs roughly $7 to $12 per square foot, and lasts 25 to 40 years. Standing seam wins on…
Joist vs Beam: A joist is a repetitive horizontal member, usually spaced 12 to 24 inches apart, that carries the floor or ceiling deck directly. A beam (also called a girder) is a single larger member that collects the loads from many joists and carries them to posts, walls or foundations. Joists spread load. Beams…
Metal Roof Snow Guards vs Snow Rails: Snow guards are individual pads or cleats spread across the roof in staggered rows. Snow rails are continuous bars clamped along the slope. Guards cost less and hide better but are only rated to roughly 45 psf ground snow load. Above that, rails are the engineered choice. A…
Joist vs Truss: A joist is one solid horizontal member that carries floor or ceiling load over a short span. A truss is a factory-built triangulated frame that carries load over a longer span with less lumber. Trusses run $5 to $14 per square foot installed and reach 40 feet. Joists cost less but usually…
TPO vs PVC Roofing: TPO vs PVC roofing comes down to exposure. TPO installs for roughly $5.50 to $12.00 per square foot and suits offices, warehouses and retail. PVC costs about $7.00 to $15.00 per square foot and resists grease, oils and fire far better, making it the standard for restaurants and industrial buildings. Both…
Metal Roof vs Shingles: Asphalt shingles cost about $4.50 to $8.00 per square foot installed and last 15 to 30 years. Metal roofs cost about $9.00 to $22.00 per square foot installed and last 40 to 70 years. Shingles win on upfront price and repairability. Metal wins on lifespan, wind resistance and cooling energy. Your…
Hip Roof vs Gable Roof: A hip roof slopes on all four sides and handles wind far better, cutting peak uplift pressure by up to 50 percent and earning real insurance credits in hurricane states. A gable roof has two slopes and two vertical end walls. It costs less, ventilates easier and gives you roughly…
Rafter vs. Truss: Rafters are cut and assembled on site from dimensional lumber, giving you open attic space and easy field adjustment. Trusses are engineered assemblies built in a factory, spanning further with less lumber and far less labor, but their webs fill the attic and you cannot legally cut them. Both build the same…
Rafters vs. Joists: Rafters are sloped members that carry roof loads down to the exterior walls and push outward as they do it. Joists are horizontal members that carry floor or ceiling loads in pure bending, with no outward thrust. Rafters need a tie or a ridge beam. Joists do not. That one-line split hides…
