Installing a simple roof on a heritage home is a complex project. What is sure is that when the house was built it was probably done a little differently than a home is built today. The entire structure is older than your grandparents and tearing off the roof is pretty tricky. Even twenty years ago when roofers had a strange habit of going over the original roof that it is common to find Vancouver heritage homes with three layers of roofs. When hiring a roofing contractor they should definitely know how many layers you have before you sign on the line. Finding a extra layer during production is costly.

It can weigh quite a bit if there is suddenly an extra layer. What you will find out is the first layer is cedar. Good old, and I mean old Vancouver cedar. You cant get Cedar like that anymore, but it is definitely expired. In Vancouver heritage homes have steep pitches and weak decking. An increase of ventilation cause you probably getting laminate fibreglass shingles which means you getting a plywood deck.

Roofing on a Vancouver heritage house is quite is often done on a forty five degree angle. The house probably wasn't built to today’s building code and probably does not have soffit vents, this is a issue when vaulted ceilings sit below a new deck. Soffits vents can be installed but has to be inspected for each home by the roofer or carpenter first.

Vancouver heritage homes are clustered together with some gaps from eave to eave of each house actually overlaps. Heritage homes seem to be on average about two feet from each other. Protecting your neighbours home becomes a difficult task in some circumstances. Damaged siding can be expensive to repair on a heritage home and ruining a good relationship with your neighbour is a long term situation.

The roof deck on a really old home is probably strapping so plywood then has to installed. I haven't seen any heritage homes getting a cedar shake roof but I am sure there are some. A common negative issue with heritage homes is the chimney is pretty old and often falling apart. depending whether you use this chimney or not is a big facture on the options you have.

Most siding is still the siding the house was built with. Wall flashing and step flashing was not built with the house and so installing flashing can be impossible in some cases. Flashing means the metal that stops water from sliding between things like a wall and roof. Old siding on heritage homes in Vancouver can mean that the roofer only has the choice of a short term barrier like caulking or gluing the flashing above the siding. Watch out and make sure they do not damage a well preserved heritage house. If the owner insists that flashing be installed the roofer will often hand over the liability of the siding over to you. Dry rot is a major issue with these old houses so be prepared for carpentry work.

Each and every heritage home has it's own issues and one must play it by ear. Most problems you should see before the situation arises but always be ready for the unexpected when dealing with a Vancouver Heritage home
