Flat Low-Slope Roofs
- Torch-on Roofing: make sure you leave this roof repair to the qualified experts at D&D Roofing as we use high heat and open flame to melt and unroll the modified bitumen or asphalt single-ply solution.
- Tar and Gravel Roofing: as there are multiple layers of material used in this type of roof (waterproof material, tar, and smooth river stone), you’ll need the D&D roofing experts to identify and repair leaks and drainage clogs.
- Rubber Roofing: the experts at D&D will ensure the chemical glues are properly applied and special attention is paid to pipes and ventilation to prevent leaks.
- Thermoplastic Roofing: great for planted “green” roofs, our reliable single-ply roofing solution uses heat to weld the seams together, resulting in a very strong, water-tight bond that doesn’t degrade over time like a chemical weld might.

Whether your roof uses metal sheets, panels, tiles, standing seam, corrugated metal, metal cladding, galvanized, galvalume, interlock, or any other specialized metal roofing solution, we can help you with your metal roofing repairs. We can even colour-match to your existing roof.

- Curved, Vaulted, and Barrel Roofing: don’t risk your safety with these varied pitch roofs. We have experience and equipment for safely dealing with the inspection, maintenance, and repair challenges of these types of roofs.
