Flat and low-slope roofs need specialized attention. Unlike steep shingle roofs, flat roofs depend heavily on drainage, membrane condition, seams, flashing, roof edges, and proper installation. Small problems can become expensive if water sits on the roof or enters the system.
Professional Roofers is a licensed and insured Toronto roofing contractor serving homeowners and businesses with residential flat roofing, commercial flat roofing, roof repair, replacement, emergency repairs, and related roofing services.

Common warning signs include:
Flat roofs are not truly flat. They need proper slope and drainage so water can move away from the building. Poor drainage can shorten roof life, increase leak risk, and damage insulation or decking.
Some Toronto homes, additions, garages, porches, and low-slope sections use flat roofing systems. These areas need proper membrane details, flashing, and water control.

Commercial flat roofs often have larger surfaces, rooftop equipment, drainage systems, and higher maintenance needs. Professional Roofers provides commercial flat roofing and commercial roof repair.
Repair may be enough if the damage is limited and the roof is otherwise performing well. Replacement may be recommended when there are repeated leaks, widespread membrane failure, insulation damage, poor drainage, or aging materials.
Professional Roofers has 25+ years of experience serving Toronto and the GTA, with residential and commercial roofing services backed by strong local trust signals, manufacturer certification, BBB accreditation, HomeStars recognition, and hundreds of public reviews.

PROFESSIONAL ROOFERS (a division of UXDU Contracting Inc.) offers one of the best residential and commercial warranties around.
Whereas most warranties cover only labour charges, leaving the customer to pay for material, tear off and disposal, Professional Roofers strives to go the extra mile and provide the customer with peace of mind and offers a non-prorated* warranty.
Our non-prorated* warranty covers: LABOUR, MATERIALS, TEAR OFF, and DISPOSAL.
If you have problems with your new roof and which relates to a defect in the materials. Professional Roofers will cover you according to the manufacturer’s warranty specifications for the materials we used on your house or building if the manufacturer fails to fulfil its own warranty for some reason other than the act(s) or default(s) of the customer.
ROOF SHINGLES: Our non-prorated* warranty is from 10 to 15 years depending on the package you choose when you sign the contract.
METAL ROOF: Our non-prorated* warranty is 15 years depending on the package you choose when you sign the contract. Our warranty does not cover animal damage, wind damage or any other acts of Mother Nature, discolouration, fading, corrosion, rust, fire, falling objects, or if the roof is mishandled, modified, or altered.
FLAT ROOF: We offer a five (5) year limited* warranty with respect to defects in installation.
EAVESTROUGH AND METAL WORK: We offer a five (5) year limited* warranty with respect to defects in installation and a twenty-five (25) year limited* warranty with respect to defects in materials.
SMALL REPAIRS: Normally we offer a one (1) year warranty for the area which we repair, only. However, if the problem occurs again during the one (1) year period, we are always willing to go back one more time to try and find a solution free of charge. If the problem continues thereafter, Professional Roofers will usually suggest a larger repair or new installation for which there will be an additional charge. If a whole new roof is required, the fee for the repair previously charged will be deducted from cost of the new roof.
