Vancouver Roofing Contractor And Laying Plywood Of Shiplap

When you get a roofing estimate from a Vancouver roofing company and you have a shiplap deck then the roofer should have a peak inside your attic. Standard rules amongst laminate fiberglass shingles is that if the shiplap is between six and eight inches in width and your roof is well ventilated then you should be safe. If you have shiplap that is wider or exhibits gaps between the boards then plywood is highly recommended.

What some roofing installers fail to realise that with bad shiplap, temperature mixed with moisture is the enemy. With the extremes of winter and summer the shiplap moves around and back and forth. The roofing shingles are nailed down and move around to. This movement can be neutralized with good ventilation, which brings me to the second problem. On top of all this movement which is due to under ventilation and bad shiplap, the shingles cook and freeze sitting on the outer layer of a extreme temperature range attic. Generally this situation occurring on a home will not see the end of the warranty. Which is not covered unless the shingle was faulty to begin with, which rarely happens

Plywood is laid down and a reliable roofing company will ventilate to today's building code. This will ensure a roof for at least thirty years and in the future not have to deal with the shiplap issues. There are some asphalt shingle roofing companies out there who will not deal with shiplap unless plywood is being laid down.

Ask for two estimates if possible to get an idea of the cost of your roof if plywood is a notion you might proceed with. Every home is different, I know in the Greater Vancouver region that some homes only need twenty years and are happy to lay over shiplap. At the end it is your home and there is no law saying you have to get plywood. But you have been warned, sometimes getting plywood is a good choice to make
