TPO Roofing Systems
In the 20+ years that TPO has been in the field, it's become one of the most popular products used for low-slope commercial roofing.
 
Short for thermoplastic polyolefin, TPO is a single-ply roofing membrane that offers excellent performance at a cost-effective price. Heat-welded seams provide superior strength. TPO's long-term heat, UV, and natural fungal resistance, plus flexibility without the need for plasticizers also make TPO a reliable low-slope roofing system. TPO roofing systems are an excellent choice at keeping your building cool as the material reflects heat rather than absorbing it.
 
PVC (polyvinyl chloride)

Reliable and versatile membrane with excellent flexibility, as well as increased resistance to UV light, chemicals, tears, and punctures. PVC membranes feature heat-welded seams, a white, reflective color, and ease of repair.

Liquid Membrane Systems

Flexible, highly-reflective, and easy to repair, liquid-applied-roofing is constructed from high-quality components that all work together to provide excellent protection from the elements.

Re-roofing

Missing a few tiles or are your shingles damaged? Re-roofing can be the way to go. Reroofing is the process of replacing your current roof covering material with new material. This is a great option if your roof's deck is in good shape and you are looking to change the look.

New Roof Replacement

You will need a roof replacement if your roof's deck is experiencing damage, rot or water leaks. Often times when people try to DIY their reroofing or hire rookie roofers is that they reroof over damaged decks. This can cause more roof damage and double the costs to replace than doing it right the first time around.

Don't fret about having to replace the entire roof over damage. If damage is minor like less than half your roof, you can ask your roofer about a partial replacement.

It's been a long time since I've had such professional work done and amazing service.
They got the right financing program for my needs and the entire project was done in a very short time...

Yelp Review

I got bids from Sunrun and SolarCity. Simmitri was comparable to Sunrun and slightly cheaper by just a hair -- what made me go with simmitri in the end was their great customer service.
