Ice Dams And Roof Leaks Soak The Insulation At The Eaves
This work is most common after a hard winter. London sits on the edge of the Lake Huron snowbelt, with about 76 inches of snow a year and plenty of freeze and thaw. Heat escaping into the attic melts the roof snow, which then refreezes at the eaves and backs water up under the shingles.
That water drips into the insulation right where the roof is lowest and hardest to reach. A slow roof leak around a chimney or a vent does the same thing. Wet insulation holds very little heat and takes a long time to dry.
Soaked insulation in an attic can stay damp for weeks, even in summer. Cellulose packs into a heavy mat, and fibreglass holds water against the drywall, which can stain the ceiling below or make it sag. The longer it sits, the more likely the roof boards are to grow mould.
Once the leak or the ice dam has been dealt with, taking the wet insulation out lets the attic dry quickly. We leave the area open until it is dry and check it again before anything new is blown in. Early insulation removal also keeps the damage smaller and easier to document for a claim.
Bathroom Fans Venting Into The Attic Grow Mould On The Roof Boards
When a bathroom fan dumps its air into the attic rather than through the roof or a wall, the steam lands on cold roof boards. It condenses, drips back into the insulation, and black mould spots start to form on the wood. On American sites this is often called attic mold.
Taking out the wet fill is the first step, because mould cannot be dealt with while wet insulation is sitting against it. The fan duct then has to be run properly to the outside, and the roof boards can be cleaned or treated once they are dry.
Smoke-Damaged Insulation Holds The Smell Of A Fire
Insulation catches soot and smoke odour even when the fire was in a room below. The odour returns on every hot or humid day, and paint on the ceilings will not hold it in.
We take out the fill, clean and deodorize the attic, and new insulation can go in once the smell is gone.
Insurance Claims Go Better With Photos Of The Damage
Adjusters want to see what was there. We photograph the attic at every stage and hand you a written scope that lists what was taken out. Sudden water and fire damage is often covered, although no contractor can tell you in advance what an insurer will decide.
After everything has dried and been cleaned, new fill goes back in through attic insulation replacement.
