Since 1921, McDonald & Wetle has been offering expert commercial roofing service throughout Washington and Oregon, with offices in Seattle and Portland. When your commercial building needs a new roof, we help you determine which roofing system works best for your situation. Your commercial roofing options hinge on your budget and the pitch/slope and complexity of your roof. We offer several roofing systems suitable for flat or sloped applications.
Many commercial buildings have roofs with a low slope. Flat or nearly flat roofs are common for industrial buildings and medical facilities with wide roof spans. Your commercial roofing options:
- Built-up roof (BUR) systems are moderately priced and the best choice for industrial buildings. BURs are appropriate for flat roofs and most low-slope roofs with a 3-in-12 pitch or less.
- Single-ply roof systems provide long-lasting, cost-effective options. The three most common types used for commercial roofing applications utilize EPDM (Ethylene Propylene Diene Monomer), PVC (Poly Vinyl Chloride) or TPO (Thermoplastic Polyolefin) membranes.
Options For Sloped Roofs
Sloped roofs are common for banks and commercial buildings with historical significance. Many retail establishments and restaurants also have pitched roofs, which is any roof with slopes greater than 3-in-12. Exact costs vary depending on your aesthetic choices and difficulty of installation.
- Asphalt or composition shingles are quick and easy to install and come in a diverse array of colors and styles. They’re a popular choice for businesses on a tight budget and appropriate for roofs with 3-in-12 slopes or greater.
- Clay tiles offer distinctive styles and colors. More durable and more expensive than shingles, tiles are a popular option for adding architectural style, especially for Spanish or Mediterranean designs. Appropriate for roofs with 4-in-12 slopes or greater, with sufficient load-bearing capacity.
- Natural slate tiles are the longest-lasting, most expensive option. They’re appropriate for roofs with 4-in-12 slopes or greater with sufficient load-bearing capacity. Slate is a popular option for historic or high-end commercial buildings.
