Frequently Asked Questions
Warranties / Emergencies
1. What should I do in the case of an emergency leak?
On a built-up roof, a can of flashing cement will do wonders. On a single ply roof system duct tape and urethane caulk may close off a hole. For all emergencies, it is best to contact Pfister Roofing’s Emergency Hotline at 1-800-367-2207 to keep damage and repairs minimal.
2. If a manufacturer warranties my roof can I make my own repairs or have my HVAC contractor flash a unit?
No! For the entire length of the warranty the manufacturer is responsible to keep the roof watertight. Call Pfister Roofing at 1-800-367-2207 for repairs or modifications to equip rooftop equipment.
3. How can I protect the roof from other trades and foot traffic?
By installing protection mats or a concrete paver system for high traffic areas (chillers, ventilation, cleaners etc). Call Pfister Roofing at 1-800-367-2207 to install protective pathways for rooftop foot traffic.
