Single-ply roofing sounds simple, but the quality of material you select for your building will actually spell the difference between years of reliability or immediate reinstallation after a few weeks.
Before deciding on the right material (and subsequently, the contractor), consider what roofing in San Diego the material will be used for. Ask yourself:
- What is the building’s height? What kind of floor plate does it have? What is the type and slope of the deck? How about roof access – will the roof be able to accommodate industrial equipment on-site? If yes, what is its maximum capacity?
- Climate is a crucial factor. Do you get more heating over cooling days, or vice versa? How many inches of rain in a year? How about the wind speed? Do you get wide temperature swings?
- There are also location-specific factors. What kinds of materials are available from local contractors? How many are qualified to install commercial roofing in San Diego, CA?
- The purpose of the building can also be a factor. Will it be a school? A food service business?
- Sustainability and environmental issues are factors as well. Some materials like EPDM are not recyclable. Does the roofer in San Diego have its own or can they recommend a recycling program? Which material is sustainable?
- And finally, government requirements. What are the building and fire codes in the area? How about zoning laws? Are there local ordinances that affect the building’s appearance, construction hours and noise levels?
Once you have these questions answered and the facts on hand, use the following guide for selecting the material for your single-ply roof:
- Choose the appropriate color membrane for the building. The rule of thumb is: use a dark-colored membrane when heating days are dominant and light-colored ones if you get more cooling days.
- Wider membranes for wide open spaces. Seams are the most vulnerable part of a membrane, so the lesser the seams, the better.
- Pick the attachment method for the insulation (or direct membrane). While single-ply roofs are commonly installed using mechanical means (i.e. screws and plates), adhesives may be more appropriate, especially on concrete decks. The contractor should also ensure that, regardless of method, any surface deterioration should be addressed before performing any attachment procedure.
- Choose a system that is appropriate for the building’s purpose, i.e. a puncture-resistant system for a school; use a corrosion-resistant termination bar if the site is exposed to corrosive factors like sea air; and make sure a hard substrate supports the membrane.
