It can be frustrating when the closing date is coming up and not sure if the roof will perform as it supposed to. When it comes to a structure of a house or building the most important key players are the roof and the foundation.
If the foundation is in good standing and no moisture marks or leaks it is a good sign. If there are damp sections or visible cracks, it can be a potential problem eventually. I am not sure when the building code has changed about the waterproofing membrane against the foundation walls and whipping tile systems but if your house has water proofing membrane it is a good thing. If there isn’t a waterproofing membrane against the foundation, i would have the foundation walls inspected very closely because it will cost you tens and thousands to have it repaired properly. If there are minor cracks on the inside foundation walls, that can be injected with liquid expanding epoxy and have it fixed.

The roof may look in okay shape from 30 or 40 feet but there may be cracks, lack of underlayment or ventilation, lack of insulation or even shingles that are completely bone dry. An average roof repair can cost you anywhere from 250? and up depending on the roofing company you hire. Cost of replacing a roof is determined by the difficulty level, total square footage and how many valleys and hips. Installing proper ice and water shield and sealing the entire roof with tar/felt paper is a step before installing the actual shingles. It’s not about the name or brand of the product, how it has been prepped and how the shingles has been installed is the most important.

I have been installing shingles and flat roof membranes for a long time and there are many different brands of roofing products out there to choose from. They are all made from the same mixture of materials. One brand can be darker than the other or other brand may have variety of colors to choose from. I personally think that it’s not the brand of the shingles that matters. If you ask why; there are many factors involved in the life span of your roof, for example underlayment, ventilated soffit, roof vents, slope of your roof, location of your house and on and on.

You can install the identical shingles on two different houses in two different locations and the one that’s less visible to sun, better ventilated and with a better pitch will last a long time to age. On the other hand if the house is right under the sun all the time, poor ventilated and has low-pitched slope on it will get fried.

Choosing a mid range color is a key when it comes to replacing your roof. Darker colors will attract the sun and life span will be shortened. Lighter colors are in the same category but opposite reaction to the sun. Sun reflects of the brighter colors and there is still a big impact on the life span of the roof. Mid range colors are always out there but they are not flirting with the sun. Sun is a player and it will burn you down as soon as you turn around.

Always inspect your soffit to make sure it is not blocked by insulation and there is a path for the fresh air to flow. Ventilation is a must, your attic should be same temperature as the outside. Make sure according to the sqf of your attic, have enough ventilation installed.

Always hire a trusted roofing company that you can depend on. Ask family or friends for advice if you don’t know any. Search on the internet for reviews and ask for references.
