5 Unexpected Dangers of an Attic/Roof Leak

Because it is often out of sight and not used on a daily basis, damage inside an attic or roof isn’t typically visible to the average homeowner. As such, it's not always apparent that roof leak repair or attic leak repair may be required. In springtime, when seasonal rainfall engulfs the Greater Toronto Area, roof leaks and attic leaks start to show up.

The truth is, even a small leak can become a big leak and quickly penetrate the attic space, thus causing all kinds of damage. At EcoComfort, our attic and roof specialists provide the necessary repairs to get things back on track. Whatever the issue, it should be immediately addressed.

The Dangers of a Leaky Roof

A leaky roof can be a real pain, and finding a remedy can be frustrating. Beyond the inherent mess and potential damage to insulation, there could also be structural damage. So, the best approach is actually the preventive approach – and that may involve regular attic inspections.

Structural Damage in the Attic

A serious roof leak can easily damage the rafters and joints inside the attic cavity. But there’s more – water damage can affect ceilings and even walls. As well, ceiling-mounted light fixtures can be damaged along with ceiling fans. These signs point to the need for immediate repairs.

Mould Growth Through the Attic

Mould growth is one of the biggest problems resulting from a leaky roof. While mould tends to grow slowly and steadily, it can spread quickly, causing damage throughout the attic and roof cavity. One way or another, it has to be removed, and it must be remediated by a professional.

Fire Hazard with Water Damage

The attic typically has electrical wiring running from end to end. A leaking roof can easily short out the wiring, consequently posing a potential fire hazard. With severe water intrusion into the attic, it would be wise to shut down the main electrical in the home to avoid any calamity.

Possible Water Pooling Hazards

A leaky roof can cause water pooling in various parts of the home. While repairs are underway, it's a good idea to take preventive measures to avoid slips and falls (especially for young kids and the elderly). It sounds like obvious advice, but severe leaking causes high volumes of water.

Damage to Insulation Materials

Roof leaks will often cause existing insulation material to become waterlogged. Wet insulation is practically impossible to effectively dry out. In these types of situations, there’s no alternative but to undertake expert attic leak repair and roof leak repair followed by insulation replacement.

Very efficient service from quote to the completion of the job 2 days later. Thanks to EcoComfort, we now have baffles in our two attic spaces as well as insulation that went from extremely poor (builder's quality of 4") to R60. We're extremely happy with the work done and would not hesitate to recommend EcoComfort. Thank you very much!!

From inspection, quote, job, clean up and final inspection of the finished work, Eco Comfort Insulation did a fantastic job. They answered all my questions in detail during the initial consult, and did a great job. They cleaned up properly, and left after I was satisfied. I would highly recommend them to anyone looking to increase their attic insulation. Thank you.

I'm very pleased with EcoComfort. I called them for an attic insulation top up. After the first phone call, someone came to have a quick look at my attic. A few weeks later, two men and their truck came and increased my attic insulation from R21 to R60 with blown-in cellulose. I appreciate that they use Canadian materials (Climatizer Plus). The work only took a few hours and they left everything just as they found it, nice and clean. My house feels a little cozier now with the added insulation. Thanks a lot!

I had a wonderful experience with the Ecocomfort team. I originally hired them to top up my builder-grade insulation from 8 inches all the way up to 24 inches which is approx R-70 and they did a fantastic job. A huge shout-out to the entire team including Arnold, Patrick, Daniel, Louis, Adam, and Paul. Every one of them was friendly, professional and efficient.

Very unusual these days to find a home contractor who in fact lives up to or exceeds their claims and online revues. Wojtek was prompt, courteous, extremely knowledgeable and very patient.........he answered all my questions. Patrick, his brother and his two colleagues arrived on time, were careful and tidy, did an excellent job and cleaned up beautifully. I was skeptical of the purported benefits of adding attic insulation but during this recent late summer heat wave I have not required air conditioning during the day and only a bit overnight. Aside from potential future energy savings, the benefits were immediately evident. I would highly recommend Ecocomfort to anyone considering anything they do.

For 800 sq ft attics - EcoComfort Insulation price was HALF what 2 other insulation contractors quoted me. Very professional starting from the quote (Wojtek) - who explained the process, to the guys who did installation, very efficient and professional, - vacuumed and cleaned afterwards - can't wait to see how it retains the heat on these colder evenings. Highly recommend them.

Tom and co. were amazing!! They just completed the job within 3hrs and I had zero insulation to begin with so it was a big job. They were truly professional, cleaned up after the job and walked me through the inspection. Ontop of that, they also helped fix a small leak in the roof which they noticed during the job!! That's service beyond and above and truly appreciated!! Looking forward now to having warmth in the bedrooms this coming winter and would definitely recommend EcoComfort to anyone! You guys are awesome...

We had a great experience with EcoComfort. Arnold attended our home to provide us with a quote, and he explained the whole process and answered any questions we had. The insulation itself went well- two workers came to do the job. They cleaned up afterwards. We already notice a difference with our second floor feeling less hot in the summer heat now that we have our attic insulation done!

I hired EcoComfort Insulation after researching the more labour-intensive option to replace the batting by hand. It was like a mountain range of pink batts in the attic which was honestly a bit terrifying. Patrick sent a crew with a truck which sucked the old, dusty, pink stuff out and blew in new R60+ cellulose. I am so happy I went with this installation method and it was well worth spending the extra money.

I had Eco Comfort in recently to blow in new insulation after we had recently taken down and installed a new ceiling. Everything went very well. Everything from getting the quote, scheduling the work, and the team coming out went very smoothly. Everyone was very friendly and the crew did a great job. I would definitely recommend them to anyone.

The guys did a spectacular job in removing the old insulation and replacing it with cellulose. They were friendly, efficient and professional. They also installed a bathroom roof vent for better air circulation AND installed weatherstripping for our attic hatch. After work was done, they cleaned up the minimal dust that occurred and left our place as if they were never there. This company provides awesome service. Hire them!
