roof repairs

If you are thinking of replacing your roof,you might find yourself wondering what other parts of your home might need to be replaced or updated. With regards to this, most homeowners find themselves wondering if during a roof repair they will need to remove, repair or replace the roof insulation before the process kicks off. And if the insulation needs to be removed or replaced, what are the steps the roofer needs to take?

Below are answers to some of these questions that will help you go through your roof repairs and replacements smoothly.

What Exactly Needs Replacement?

Will the roofer need to get rid of the roof insulation in Ottawa before the replacement process starts? Well, this depends. But in most cases, he will not have to. Provided the decking is intact and does not show any sign of damage, the roofing company you contract to carry out the roof repairs will leave it intact. They will only tear out the asphalt and shingles to gain access.

The roof insulation is located below the decking right against the roof sheathing and studs. As such, there is no need to tamper with the insulation. This is unless some damage is noticed on the decking. Then you just might have to replace insulation after the hired roofer has removed the decking.

You should note that different homes feature different insulation in Ottawa. These things need to be handled differently. If you are not well-versed in roofing insulation, you should not worry. Most roofers are knowledgeable, well-trained and familiar with the various roof insulations. They will know what they need to do in the event your insulation needs replacement.

Rot, Mould, and Leaks

In homes that have leaks, roof damages usually follow closely. And here is the worst thing about leaks, they are not always brought to light by drips from the ceiling. Some tend to be covert, and you only notice the damage caused when the roofers tear off the shingles for replacement.

If the roof leak was serious, there are high chances that it got to the roof insulation. When the fiberglass insulation gets wet, the thermal properties are highly compromised. Water molecules replace air between the pieces of glass and mould grows with time. If the fiberglass batts get wet in the process, the insulation will need replacement.

If the professional roofer you hire notices signs of leakage on the interior wall, then he will recommend taking more intrusive and aggressive measures to remedy the situation. This may include hiring an expert and professional mould remediation company. But before you freak out, before things get to such critical levels, there will be some warning signs that might help you catch the problem in its early stages.

Insulate During The Roof Replacement

If you feel your roof could do with some insulation, seize the opportunity during the roof replacement project to get it installed. This is especially if you intend to install the rigid foam insulation which involves removing the shingles to gain access to the sheathing.

If you have roof insulation already, but still feel drafty or chilly, you should consider adding to it. Improving on the insulation will help reduce your expenditure on energy bills.

Conclusion

While getting a new roof installed may provide you with an opportunity to have the insulation inspected and repaired, it is not a requirement to get rid of it before the project commences and the assessment is done.
