How the Stuff on Your Roof Affects a Roof Replacement

How the Stuff on Your Roof Affects a Roof Replacement

Just take a look at your roof and you would see it looks perfect and smooth. However, it is not that smooth as it has many vents, turret, chimney and dormer in the sight. All of this makes roof replacement an easy process. However, these things also make the roof replacement process a little trickier.

Working around the shapes and objects on your roof

Roofs with certain shapes and features can be more challenging to replace than others. If there is any deflection from a flat deck, there will be a ridge, valley or seam which will require extra attention from the roofers so that water penetration can be avoided.

Moreover, the base mat of the roof would require more custom cutting and you can use special flashing for the roof. You can also apply the shingles in a different manner and design. The roof would require ventilation and for that vents are needed. If your roof is not getting proper ventilation, it would start getting damaged prematurely. Let’s have a look at the way that can be used to address the roof’s unique waterproofing and ventilation needs.

The unique Roof and Its replacement

Chimneys and Exhaust Vents

The problem these two things can cause is leakage and the solution for them is cricket, flashing, sealant and underlayment.

Many homes have at least one chimney –even when there is no visible fireplace. Chimneys need extra attention during a roof replacement.

Is your chimney penetrating the roof deck?

If such a thing is happening, you can install a cricket at the side of the chimney closer to the roof ridge. The cricket is made of two small pieces of wood which can be joined at a ridge. The cricket is perpendicular to the house roof ridge.

If the water is flowing down the shingles and the cricket diverts the water around the chimney. Suppose there is no cricket there, then flashing can perform the job.

  • Chimneys also require a special flashing method. The unique step flashing or corner flashing can be used around a chimney. Moreover, underlayment is also used at such places to avoid any kind of penetration of water.
  • Next comes the exhaust pipes which will leave extra room for the water to penetrate which can be avoided with the use of flashing. This kind of flashing is called a flange and it fits over the pipe like a skirt. This flashing allows the water to run down the shingles.
  • Moreover, the roofing contractor Memphis must cut a hole in the shingle which comes above the vent and under the flange to provide an extra layer of protection.

Roof Style and Shape

The problem with the roof style and shape is the leak-prone valleys and the poor ventilation system.

The solution is simple but must be carefully implemented, such as underlayment, flashing, installation techniques and ventilation should be used.

Valley is present in almost every home’s roof. Water will flow down the roof through the valley and it will travel straight to the gutters. Let’s look at some of the features.

  • There must come underlayment under the valley as it will reinforce the performance and would prevent any kind of water penetration.
  • Roof contractors can use the metal valley flashing which can be effective in this case. Moreover, the installation of these flashing can be done in the form of open or closed style.
  • The shingles can be attached in the form of woven together to add an extra layer of protection to these vulnerable areas.
  • Ventilation methods vary from roof to roof as every roof has a unique style. This is why the right method and technique must be adopted for this purpose. All the vents must be kept clean and in the right position for the intake and exhaust of air.
