Common questions
How often should a commercial roof be inspected
Twice a year is the usual standard, plus a look after any major storm.
Can a commercial roof be recoated instead of replaced
Sometimes, if the membrane is sound and the insulation underneath is dry. Wet insulation has to come out whatever goes on top.
