Mold Removal

Our certified mold removal process addresses attic mold at all stages of growth. We combine specialized equipment with industry-approved chemicals to eliminate mold colonies and prevent recurrence. The service includes insulation replacement, soffit cleaning, and bathroom vent upgrades to address moisture sources. All work is backed by a 10-year warranty, significantly exceeding the 1-2 year guarantees offered by most competitors.

Roof Repairs

We provide comprehensive roof repair services for hail damage, wind damage, and general wear. Our process includes replacing damaged shingles, sealing plumbing flanges, and evaluating ventilation systems. Using premium materials like 15lb tar paper and 25-30 year shingles, we extend roof lifespan while preventing water intrusion that could lead to mold growth in attics.

Roof Ventilation

Our ventilation solutions optimize airflow to prevent temperature extremes in attics. We install ridge vents, soffit baffles, and proper exhaust systems to maintain ideal conditions. This prevents premature shingle degradation in summer and ice dam formation in winter, while also reducing the risk of mold growth from trapped moisture.

Maintenance Package

This preventative maintenance program includes shingle replacement, vent sealing, and plumbing flange checks. We evaluate roof life expectancy and ventilation efficiency to identify potential issues before they become emergencies. Designed for roofs over 10 years old, this service helps homeowners avoid costly replacements through regular upkeep.

Insulation Installation

We install high R-value insulation after completing mold remediation or roof repairs. Our process ensures proper airflow while maintaining energy efficiency. We use baffles to prevent soffit blockages and address common moisture sources like bathroom exhaust systems, creating a balanced insulation solution that protects both structural integrity and indoor air quality.

We have used their services for Roof Installation and Snow Removal. Since last 4years Woow Roofing & Snow Removal company has been taking care of snow removal job, always on time and does a good job. We have renewed our contract for 2020-21. Even when we were away on vacation we could see on our security camera that our driveway was cleaned after every snow fall.

Tony & team did a really good job repairing our roof..he was prompt , efficient and effective in getting the job done right . Having had two previous roofers here in the past to repair our roof and only spend a few minutes nailing down shingles .Tony was the only roofer to inspect our attic and ensure we were getting proper air flow . Thank you Tony for being so knowledgeable and letting us know why and what we were getting done

Tony was the only roofer that bothered to check my attic. Just to make sure that I had proper ventilation to ensure a long life to my new roof. Some roofers my finish in a day. Tony had a team of guys here that worked hard and it did take them a while but the roof looks great.

Always punctual and delivered quality work. Even came out on Christmas Eve when no one else on our street had their driveways cleared by other companies. Always friendly and courteous. Salted and cleaned up in between snowfalls even when it wasn't set in my contract. I'll definitely be going with WOW again next year. Thank you so much for helping us through our winter. Definitely considering having them do snow removal and roofing at both my rental properties. It's always difficult to find a good contractor and we found one. ThanK you so much guys.

During the wind storm we had last week in the GTA, my roof and gutters were damaged. After a week of getting no where with voicemails and emails with other companies, 1 phone call was all it took for the owner Tony and his son JJ to come by and fix everything. I was able to book an appointment, agree on a great price and have THE JOB DONE all in matter of hours. If ANYONE, ANYWHERE IN THE GTA needs GOOD, TRUSTWORTHY ROOFERS, CALL WOW!!!!! Thanks again guys!

Great reliable service. Tony and his crew always show up, do the job as expected and has even went the extra mile to shovel my walk way and stairs as I am unable to do so as I am disabled. I've never once in the two years of using his winter plow service have had any issues. Thank you Tony for such an exceptional professional job! See you next winter!
