Redoing my roof: how should I redo my insulation?


If you're getting your roofing materials replaced and the roof decking exposed, you have a golden opportunity! What you could do is add several inches (4+", preferably 6+") of roofing polyiso over the exposed roof decking (no need to remove it unless it's rotten or moldy) before installing new underlayment and roofing. Use foil-faced polyiso for the top layer, then install vented ridge-to-eave purlins and cover that with foil-faced roof decking with the foil facing down. Then install the new underlayment and roof over that. Many roofers--including nearly all who do commercial jobs--will be familiar with this approach.

This will transform your roof into a "hot roof" with a radiant barrier and ventilation over the insulation, and the attic will be transformed into "interior" space, if that's something that would be desirable. A part of this work would be to remove/block off the old soffit vents, ridge vents, turtle vents, gable vents, or any other vents. The only ventilation...

So you’re getting ready to put your house on the market. Moving is a big decision, whether you’re upsizing to fit your growing family, moving to a new city, or looking for somewhere smaller to settle during your retirement.

You want your house to sell for the best possible price – and you’re wondering whether redoing your roof will have a significant impact on the resale value of your home.

Well, one of the most important things that contribute to your home’s value is how well it has been maintained and kept up. Smart home buyers know that a house in good condition will serve them better in the years to come than one that is aesthetically pretty, but full of structural issues.

Fancy upgrades are nothing in the face of making sure the basics are in prime condition. The roof is absolutely one of those essential basics that must be addressed if you want to get top dollar for your property.

loss of grit

broken or partially missing shingles

bent, lifted, or curled edges

shingle edges don't look like they have "square" corners any more

look for places that have high water flow will be in worst shape.

when walking on it you feed 'soft' or bouncy spots that are not the same as other parts of the roof

if you can lift the bottom edges of shingles up from the ones they are supposed to be glued to - BAD!

When you have water dripping from your ceiling you definitely know its too late
you may actually have drips, it doesn't mean that you are going to see it. sometimes it can run down insides of walls, or make your attic insulation soggy and mouldy. you need to also inspect the inside of your attic to see that there is no water damage on the wood on the inside of the roof.
Also 2 layers of shingles is the wrong way to have done it. it does not offer any better protection than a single layer, and is very heavy and hard on...

I am building a log house and am at the point of insulating my roof. It is a metal roof with 2x10 rafters. The guys I am hiring to insulate said I have a couple of options. Condensed fiberglass R-30 batts are out because they are special order and I can't get them for 2wks and the guys are coming next week. I could put 2x2 furring strips to create the 12" I need for air flow and do regular R-30. I could do spray foam. They said 1". and then do the regular R-30. This woul give me about R-37. Or I could do blown in fibergalss insulation. They said with it being condensed I could get R-38. My concern with the blown in is the lack of air space to prevent condensation. They said that with it so densely packed in the air space wouldn't be necessary. It seems everyone has their own opinion about how things should be done. I am finding this throughout the whole project, 3 years in the making. : ) Thanks for any advise you can give me. We are covering the valted ceiling with T&G. I don't...

Your roof is an essentail home improvement. The roof is your umbrella to your home. The average roof lasts 17.85 years. So if your home was built in the 1990’s it is most likey due for a replacement.

You should replace your roof first- you live in Oregon!

If your roof needs to be replaced, put it at the top of your rennovation list. Oregons consistent rain can cause rot and mold to grow in your wood, drywall and insulation in your attic. Proper roof installation is the most important part of getting your roof redone.

Proper Installation Process

Full Tear Off Replace all rotted boards New 30 pound felt Then you can install the New shingles New flashing New valley metals

Roof Terminology:

Roof Square- A unit of measure equalling 100 square feet. Root Vent- The vent runs along the ridge of the roof, so that the roofing does not buckle and deteriorate over time. Shingles- also called the composition.

My roof leaks. Do I need to have it totally replaced?

Not necessarily. Leaking can result from damage done to a section of the roof or from flashing coming loose. A roof failure, however, is generally irreversible and result from improper installation or choice of materials, or from the installation of a roof system inappropriate to the building.

How should I prepare for the installation of my new roof?

You should remove all loose items from your walls and shelves. The constant hammering may cause enough vibration to shake these items down. Make sure you have your driveway clear as well as the areas surrounding your home. This is because of the chance that material from the tear off could fall in the driveway or the area directly around your home. This will also give your contractor a place to store the material for your new roof as well as a place for the dumpster. Make sure the contractor puts plywood down in the driveway to protect it.

We don't give out forms here, as that would be considered entering into an attorney-client relationship and is against state law if we are not meeting face to face. However, I can give you some suggestions on what you may like to include in your own form. First let me tell you a little bit about the law with regard to this.

This question is far more complicated than it might appear. It has been the subject of a number of appellate court and Supreme Court decisions the last few years. If a contractor doesn't have worker's compensation, and a worker gets hurt while working on your home, then the worker can bring a claim with the Uninsured Employers Fund and also bring a personal injury action against the contractor. Success depends on whether the contractor was somehow negligent, but it can nearly always be shown that the contractor was at least partially negligent if someone gets hurt on his jobsite. Plus, if the contractor didn't have worker's compensation then a...

The question ‘how often should I redo my website,’ yields some questionable results on Google’s results page. Article after article told me I should redesign my website every 2-3 years to keep customers happy and engaged.

Asking when to redo your site is like asking how often you should call your mom. Well, how often do you call her now? Is she happy with the amount you call her? Are you happy with it? In what ways could you both benefit from talking more or less? The answer completely depends on your situation and can’t be answered reasonably without much more information from you.

So back to answering the question. How often should you redesign your website? It depends. But it all comes down to your answer to the following question.

“Is my website continually producing satisfactory results?”

If your answer to the question is “yes,” and you haven’t updated your site in 5 years, or just redesigned last month, your decision should be obvious. To...

To the OP:

Don't let all the cautions from all of us scare you off the job. What they should do is make you realize a) roofing is hard physical work, b) it can be dangerous (fatal), and c) there's a lot you need to know about.

There is nothing technically difficult about the majority of roofing tasks. The key is getting yourself educated about them. Personally, I will and have tackled almost any home repair/maintenance/improvement job around the house that I'm pretty sure is within my physical abilities. I often have to learn on the job, but there are lots of good sources of information available. The library is certainly your first stop. The places that sell material supplies may also have some experienced people who can give good advice -- however, you'll also run across bozos that don't know what they're talking about -- and it's you're job to figure out who's who.

If I were in your shoes, I'd try to find a roofing contractor who would let you help (for free) on a...

Dear Mr. Rafferty- My husband joins me in thanking you for completing the job of replacing our roof with speed, efficiency and professionalism.

if this is a worthwhile exercise?
Depends if your roof need work other then a coat of paint. Money wise I think the answer is no, unless you do it yourself. The industry from my experience and my parents experience is that there's alot of dodgy applicators out there to make some easy cash and do less then average jobs. I thought I was using a good company...turns out they are no longer in business and we were taken for a ride...the company subbed out to a bunch of idiots.

in 5 years time does it end up looking the same?
mine had faded around the 4-5 year mark, and not just that it lost it's gloss, it faded 2 shades of colour...was charcoal and is now close to slate grey if I look at the colour chart we still have.

do they use a sealant also?
they should have, but I wasn't around when they did I don't really know.

It's now 9 years since my roof was 'restored'. Great term that...don't expect restored means it will...

I was recently chatting with a neighbor who asked, " We love our 100 year old home. However, it sure is a drafty old place! We're interested in blowing insulation into the walls, what do you think Bob?"

Let me start by saying, if you live in an old house you are part of a large group of plaster dust lovers. I have great respect for and kinship with people choosing to live on tree-lined streets full of unique old homes with character.

Having said that, it's time for an old house reality check. If your goal is to continue loving your old house, make it energy efficient while keeping your costs down, then you absolutely don't want to blow insulation into the sidewalls.

One of the top reasons for exterior paint failure, termites and structural damage to old houses is loose cellulose or fiberglass insulation blown into the sidewalls. "Hey, wait a minute Bob, if we can't insulate the sidewalls, how can we afford to heat our old house?" That's a valid question but you...

I was about to launch into an article on insulating empty wall cavities in an older house when I realized that the topic is best broken down into two sections: a survey of the products you can use to insulate your wall cavities, and a discussion of installation techniques and methods. I'm just glad I realized that in the first paragraph as opposed to the fifth page. So this article will focus on insulation materials.

Important Note: In this article, I am only talking about insulating existing wall cavities in an older house. This article is not about wall insulation in new construction. I would've had to take a “No Country for Old Men”-style air gun to the head to tackle that large a topic in one post.

Also, we're only talking about closed wall cavities. We'll deal with roof trusses and gut rehab jobs another time.

Five options

Short of gutting the wall cavities, which would allow full access (and all possible options), there are five insulation...
