We are disappointed in their response to our calls...

We are disappointed in their response to our calls on when they need to repair the roof. We have a TPO 15 year roof installed by Queston for the previous owner of this house. Queston inspected the roof previous to our purchase of the home.The roof passed Queston's inspection for closing. They also did some repairs around the parapets prior to our closing.(no warranty on that procedure) There was still 4 years left on the roof warranty. The roof began to leak about 2 months or so after we closed on the home. It has leaked quite a few times. They sent one man out with a chalking gun a few times. It takes them a few days to a week to send the man with the chalking gun out. The damage on the inside is not covered under their warranty. They have gotten tired of me calling them. We have not had a flat roof before and we were not aware of the maintenance required. Finally we just gave up on Queston Construction. We have paid another roofing company to re-weld seams and to maintenance the metal spouts that the water drains out of on the sides of the roof. The other roofing company is much better than Queston and they informed us about things that need to be serviced etc. The next time we do need roof repair or a new roof I will call this other company. Dealing with Queston Construction has been stressful and a waste of time. Their warranty is not worth anything at all.
