Roof ventilation is a tricky subject but it is very important to consider when doing a roof replacement.
What is Roof Ventilation?
In a nutshell, roofing ventilation means allowing air to flow into and out of your attic area. The ultimate goal is to have the temperature of your attic to be as close to the temperature outside as possible.
Some people get the idea that you should insulate your attic and keep it sealed up. This is incorrect. You want your home to be sealed and insulated, but your attic should have nice open airflow at all times.
This allows hot air to escape in the summer, keeping the attic cooler. And in the winter it keeps the roof surface cold.
The reason you want the roof cold in the winter is that if the roof is warm, when it snows, the snow on the roof melts, and then freezes again when it gets Read Full Article »
This is one question that comes up a lot. Your roof is getting on in years but you are planning to sell in the near future. Is it better to let the next guy deal with it or should you take care of it yourself?
Well there are a few things to consider. For one thing you should know that any sensible home buyer is going to have a home inspection done before buying. And any home inspector worth a darn is going to take a good hard look at that roof. He is working for the potential buyer and he is going to make sure he finds every possible problem. That’s his job.
Then the buyer is definitely going to bring up any problems the inspector found in the negotiating process. And their game will be to use any problems against Read Full Article »
A Little Knowledge Can Save You Money
While there is no substitute for the opinion of an experienced professional, having a little knowledge about what to look for will help you make an informed choice about what action to take.
No one can predict exactly when a roof will start to fail and leak, but there are signs you can look for that show it’s time to start thinking about replacement:
Missing Granules from the Asphalt
Missing granules: viewed from the ground this looks like dark patches (or lighter patches if the shingles are black). What you are looking at are patches on the shingles where the granules have fallen off.You will also notice large amounts of granules in the gutters when you clean them. The granules themselves are not responsible for waterproofing so if they are missing you won’t necessarily get leaks, but the granules protect the asphalt in the shingle from being damaged by the UV rays of the sun. So once they go, the shingles will wear out faster. Read Full Article »

Well here we are again in Vancouver’s rainy season. Funny how it always feels like summer will last forever isn’t it? The weeks of hot dry weather can make it feel like you will never need to worry about heating, insulating or keeping the water out of your home. In fact, you worry more about how to keep cool!
But every year it comes sloshing back in, the sullen grey reminder that, beautiful as it is, we live in a Canadian rainforest. And with that comes the pressing need to keep our home dry.
Cracks and Roof Weak Points

Whenever it rains in Vancouver we get lots of calls for Emergency Roof Repairs.
Sometimes people don’t know their roof is leaking until enough rain falls to bring it through to inside of the house or garage. Then it becomes an emergency roof repair and that’s never a good thing.
This is why inspection and maintenance is important. An experienced roofer can often see that a problem is brewing if he can do an inspection of the roof. Obviously this is a better solution than waiting for internal water damage to happen.

However, there are times when the leak does not come from an obvious place. Where the water damage, or drip, or water stain finally comes out, may have no relation to Read Full Article »
Your house is beautiful; everything is freshly cleaned and painted; you’ve done all your home maintenance. But with the first fall rainstorm, you find a leak! Those dreadful leaks that you have NO IDEA where they come from. It seems like the problem should be ‘just above’ where it’s leaking, but it never seems to be that way. Water can easily travel sideways before passing through a joint in the roof sheathing. The true point of the leak can be a distance from the apparent leak location.
Actually, roof leaks normally start in areas where there are ‘details’ like vents, chimneys, flashing or where the roof has ridges and valleys. A valley is a line where two roof planes intersect and can become problematic, especially if the shingles were not trimmed correctly.
Chimneys Are Very Common Leak Sources
So four years ago, owner Doug Kerr started his own roofing company – Absolute Roofing Solutions.
“We found roofing the worst trade in the construction business,” says Kerr. “But when we got into the roofing business we really discovered just how bad it was.”
To help homeowners with their roofing problems, Kerr has written a free booklet, Roofer Madness: How to avoid the roofing rip off, which is packed with all sorts of useful tips.
For example, unless you know or trust your roofing contractor, Kerr recommends hiring an independent inspector who specializes in roofing.
”You may find you need only spend a few hundred dollars in repairs now and the expensive re-roof project can be safely put off for Read Full Article »
A warehouse in Burnaby collapsed on itself yesterday and a townhouse complex in Port Moody was evacuated because of a partial roof collapse.
Snow on Rooftops
Kerr Roofing operations manager Keith Kinvig said snow on rooftops would increase in weight as it sops up a steady supply of rain over the next couple of days. A roof covered with 25 cm of snow can weigh upwards of 300 kilograms per cubic metre. “If people have a lot of snow on their roof and it continues to rain, they should be concerned,” he said of homes 30 years in age or older.

“We have not only been pummeled by the snow. Throw in the suffering economy and you get job losses and a decline in building projects throughout the construction industry in the lower mainland,” says Doug Kerr, president of Absolute Roof Solutions. “ This has made it tough on Read Full Article »
