| Turn Your Rooftop Into A Usable

  Patio Area


When Magnet Forensics of Waterloo had Melloul-Blamey Construction design their new building, Magnet Forensics opted to create a patio area on their rooftop. An outdoor rooftop patio offers more than an unobstructed view and fresh air. It also provides an area where individuals can relax, enjoy a lunch and/or cultivate a rooftop garden or flowers. Interested in investigating this option on present of future roofs, call Grand Valley Roofing and Coatings Inc. for more information. Call 519‑623-4455.



| Worried About The Use of Torches (Open Flames)?


There are alternatives to hot applications which often require the use of torches (open flames). For example, Built Up Roofs (BUR) can be applied using a cold process and no flames. Also, Modified Bitumen (MODBIT) and TPO can be applied using a peel and stick self adhering membrane as shown in this Sandhills School roof. Interested in learning more about torchless roofing, call Grand Valley Roofing and Coatings Inc. for more information. Call 519‑623-4455.
