Frequently Asked Questions (FAQs)
If your roof’s been giving you grief for a while—leaks, soft spots, cold drafts- it might be trying to tell you it’s done. A full replacement might cost more upfront, but it’ll save you the headache of constant fixes and interior damage.
Flat roofs, sloped systems, metal, TPO, EPDM—you name it, we have worked with it. Our crew’s got hands-on experience with a full range of commercial setups. Whether it’s a fresh commercial roof installation or keeping your existing system running strong, we’ve got the tools and know-how to get it done right.
That depends on what’s going on up there. A small leak fix? Not so bad. Major membrane damage or soaked insulation? That’s a different story. Instead of throwing out ballpark numbers, we’d rather swing by, take a proper look, and give you a straight answer. Just give us a ring at 647-519-5447 and we’ll make it easy.
Re-roofing adds a new layer on top of the old one—quicker, but only possible in certain cases. A full commercial roof replacement means breaking it down and starting fresh. One’s faster, one’s longer-lasting. We’ll walk you through which option makes sense for your roof, not just what’s easier for us.
Absolutely. Every project is backed by both the material warranty (from the manufacturer) and our own workmanship coverage. Whether it’s a simple patch or a full commercial roof replacement, we make sure you’re covered.
TPO stands for thermoplastic polyolefin. It’s that white roof you’ve probably seen on top of a lot of commercial buildings. Flat roofs, mostly. It’s durable, reflects heat like a mirror, and doesn’t give you too much grief over time. Is it right for your place? If you’ve got a flat roof and want something that handles weather swings without soaking up energy bills, well.
Yes, we do. Roofing issues don’t exactly wait for business hours. Whether it’s a sudden leak or storm damage in the middle of the night, PWCR has a team on standby to help. Just call 647-519-5447—we pick up, no matter the hour.
