If your commercial roof is leaking, you may be comparing options for a new roof. Be sure to look into spray foam roofing, as it can be a durable, attractive, and long-lasting roofing option. Here's some information about the foam roofing system installation process.
Start With A Roof Assessment
A foam roofing system can be applied to both flat and sloped roofs. It can also go over most types of roofing such as membrane, metal, and asphalt shingles. One reason for a roof assessment is to determine how many roofing layers are present. Building codes usually limit roofing layers, so if your building already has two layers of roofing materials, the old roof will need to be torn off before a foam roofing system can be installed.
Choose The Installation Date
Spray foam roofing has to be applied in mild weather when the risk of rain and wind is low. It's good to schedule the roofing work for early in the warm season so you're not held up by cold weather when winter approaches.
Your roofer might need to reschedule due to weather delays because if the temperatures are too cold or if the roof is wet, work can't continue. However, your roofer has some installation practices that help.
The roofer might use compressed air to dry out a wet roof so work can start early in the morning. They can also use windscreens to block wind so the foam doesn't get blown around.
Clean The Roof Thoroughly
If your roof only has a single layer of roofing, the foam can be added on top of it. The old roof has to be cleaned first. The roofer might do this with compressed air, a broom, or even a power washer. Power washing is usually necessary for a metal roof because the foam sticks better to clean metal.
Apply The Roof System In Layers
The foam is sprayed over the roof. The foam comes out of the hose as a liquid and turns into foam as it hardens. The roofer is skilled at applying it and is able to get the right thickness and slope for your roof. Spray foam dries fast, and once it's dry, a coating is applied.
The foam roof system usually has two coatings, and the second one might be applied the next day so the first coat has time to dry out completely. The purpose of a coating on a foam roof is to protect the foam from UV exposure and damage.
