How to Prevent Roof Condensation

Roof condensation is generally considered a tricky problem. It often looks like a leak, with “sweating” walls and running water inside your home. But when you look for the source, it’s likely that you won’t find any physical damage to your roof.

That’s why you should hire a roofing professional to conduct a proper roof inspection. This is the best way to confirm if the issue involves leaks or condensation problems. If it’s either, you need to take steps to correct it, but it’s important to understand how condensation forms and what you can do about it.


Roof condensation usually occurs in winter and early spring when temperatures are cool. What happens here is that the cold air and water on your roof comes into contact with the hot air in your attic and roof spaces. Since warm air has moisture, the moisture then condenses on the inner roof surfaces when it comes into contact with cooler temperatures.

This resulting problem is often due to improperly installed insulation. When there’s too much insulation, it tends to trap warm air near the roof, causing condensation. It can be a long time before you notice this problem. But with regular roof inspections, you might be able to catch the issue and carry out roof repair before it’s too late.

Wall and wood damage is also another common cause of roof condensation. When the wooden supports of your roof get wet, they naturally become compromised. This can later on result in sagging rooftops as well as mold or pest infestation.


The main preventive measure for roof condensation is maintaining proper ventilation in your roof and attic area. Ensure that this part of your home is protected from water infiltration and there is natural air circulation. Generally, at least one square foot of venting per 300 square feet of attic floor space is recommended. An even split of ridge and roof vents also enables natural wind movement that pulls warm air from the attic as intake vents bring in new air.

No hassles, no stress roofing contractor.

We've worked with a number of contractors over the years doing home improvement projects and I can say that, without question, working with Pressure Point was about as easy as it gets.

Everything about the project, from sales all the way to final inspection, went like clockwork and without a hitch.  They delivered more than they promised, on time and within budget.   We could not have been happier with their personnel, products and services.  Highly recommended!

I've changed my review from a 1 star to a 4 stars. Matt Stone got right on a pretty poor job done installing a skylight. He had his guys remove the skylight, move it, repair the roof and inside ceiling to its original state, paint it, repair some external trim that was damaged, and all within a few days after talking to him about the multiple problems. It was really an eyesore from the inside. I'd give a 5 star if this had been done well the first time. The skylight just didn't fit the space I first wanted it and was told it would. More communication about the potential problems might have allowed this to be done right the first time. But, Pressure Point Roofing gets 5 starts for making amends and correcting a pretty ugly problem, very fast! Thank you.

I needed someone to come out to take a look at a leaky roof. I contacted Pressure Point Roofing, Inc. and they came out the same day. They gave me a quote to fix the problem and I agreed to their terms. It was about 4PM and I knew they closed at 5PM but they stayed and fixed the leak at no additional cost. I was very happy and impressed. Would recommend them to anyone. Thank you Pressure Point Roofing for earning our families trust. Will definitely be doing business with you again.

I am so happy I chose Pressure Point to replace my 40-year-old roof.  The crew was professional, efficient, and answered all my questions, addressed the few concerns I raised, and made me feel comfortable, trusting them with such a big project.  I couldn't be happier with their work and the look of my new roof.
